Dinner with friends that turned into a partner swap

Just before the summer, my girlfriend and I ended up in a spontaneous group sex with a couple of friends of ours. Here is a brief summary of the parties in this story:

Vilde Thi (31)
She is together with Kristian, and they have been together for around 3-4 years. Vilde works as an IT consultant and is hired out to companies that need system developers.

Vilde was born and raised in Stavanger. Her parents moved to Norway from Vietnam to work in the oil industry. Her face is dominated by dark eyes, and a small and wide nose just above a perfect mouth. She has long, glossy, jet-black hair that she constantly has to adjust. Vilde is 164 cm tall, and grew slightly taller than her parents.

Vilde has a body that only someone so young could have. She has a thin waist that you can only imagine teenagers or mannequins in clothes shops having. It's almost an impossibility. Her hips are perfectly balanced from her waist, and her arse is in the same vein.

I've seen her get down on all fours to find something under the sofa, and can reveal that her bum makes a perfect heart shape when you see it from above ♥️. Her breasts are quite a bit bigger than what might be normal, so I'm guessing she has a B-cup. At least. She gets quite a lot of cleavage when she wears the right bra, and when she goes without - as I've noticed she does in the summer - I see that they have a shape that is simply perfect. Plump breasts.

Kristian (33)
He is together with Vilde. Kristian runs his own company with several employees where he offers services such as residential and wedding photography. He always has a camera of some kind slung over his shoulder and is keen to take photos when we're socialising. He is originally from Lillehammer.

Kristian is the complete opposite of Vilde! He's close to 190 cm tall, and with his strong bone structure and rather thin and slightly muscular body, I wouldn't be shocked if I saw him in the TV series Vikings. It's almost comical to see Vilde and Kristian standing upright together. The height difference is enormous! He's blonde and has quite a long beard and a man-bun of the "Grünerløkka hipster" type (despite never having lived there).

Marthe (34)
She's my girlfriend, and we've been together for almost 10 years. Marthe is a colleague of Vilde, and the two of them often work on the same development team when they are hired out.

Marthe is originally from Mo i Rana, but she moved to Oslo when she finished her studies in Trondheim. "It was in Trondheim that we met and got together.

Marthe's face is very defined. Her eyes are large and blue, while her nose is quite prominent but not too big. Her mouth has full lips, and is quite large - but not too large, and it matches her defined but feminine jawline. Her hair is brown-blonde in colour, and goes down to her shoulders.

Marthe is full-bodied and shapely. Full-bodied may not be descriptive when I think about it. You can imagine her having the same body as Kate Upton, but with a little more body to love. Her waist and hips give her an incredible hourglass figure. When she gets down on all fours, just like Vilde, her bum takes on a perfect heart shape ♥️ Unlike Vilde, Marthe has big, C-cup boobs. They're not enormous, but they look perfect for the body shape she has to be. At 177 cm above the ground, Marthe looks incredibly sexy in tight clothes and dresses.

Me (39)
Then there was me. Born and raised in Trondheim. I'm together with Marthe, and have had her as my girlfriend for almost 10 years. I consider Marthe my life partner and my best friend. I work as a developer in a large company here in Oslo. I met Marthe in Trondheim where we were both studying, and I came with her to Oslo because this is where she found a job.

My body is not so different from Kristian's, but I'm maybe a little thinner - and I'm not as tall as he is. I'm around 184 cm tall. I used to look more muscular when I was training MMA and lifting weights, but it's been a long time since I've done that.

I'm mostly clean-shaven in the face, and have short hair on top with a graduation on the sides. I'm getting a touch of "silver" in my hair, which is probably appropriate as I'm about to turn 40.

Time to start telling you what happened:
I was at work when Marthe sent me a message that her good friend and colleague, Vilde, had invited us to dinner this coming Saturday. We've had several such dinners with Vilde and her boyfriend Kristian, but most often it was at our place and on our initiative. "Now it was your turn," Marthe wrote that Vilde had said. I wrote back that it sounded fine, and that we should bring the wine they liked so much last time.

Wednesday became Thursday, and Friday became Saturday. Marthe spent a lot of time showering, washing her hair, applying make-up and dressing up. She found a rather tight dress with a zip at the back, which I noticed I was very excited about. It emphasises her shape in an incredible way. Especially the shape of her bum. Unfortunately it was full coverage in the front so she didn't have a neckline, but I saw that she was going braless and the tight dress revealed her boobs very well. I helped her with the back zip before putting on a pair of denim trousers, a matching dress shirt, a playful tie and then a blazer.

Vilde and Kristian live in Bøler here in Oslo, so Marthe and I took the bus from St.hanshaugen to Jernbanetorget to catch the metro. On the way, we bought several bottles of wine that we thought would go well with the Vietnamese food Vilde had said she would make for us.

We hopped off the metro and found the terraced house Vilde and Kristian live in. Vilde gave us both a hug at the door when they opened it. I had to bend down a bit because Vilde is so short. Kristian gave Marthe a hug, while I only got a "masculine handshake". Vilde asked us to come in, and we started taking off our shoes.
Kristian sneaks a glimpse of Marthe's arse

I noticed that Vilde and Kristian were wearing matching aprons. I got down on my knees to untie my shoes. As Vilde walked back to the kitchen, I saw that she was wearing a tight and short backless dress with a tie at the neck. Her incredible waist and the way she wiggled her hips as she walked made me stop to look. The dress went down a little over her bum, but wasn't very short. I saw her soft and brown thighs. Then I noticed Kristian still standing there. His eyes went from looking at what was in the bag from the liquor store to studying Marthe's arse. As she took off her shoes, she bent down with her knees straight to untie her shoelaces and put on the heels she had brought with her. I didn't see it, but I think Kristian got a very good impression of what her arse looks like.

"You found your way here easily?", Kristian asked after he'd calmed down. "Yes, it was easy to find," Marthe replied as she bent over and fixed her hair and jewellery. When we entered the living room, we each got our drink glass in our hands. It was a margarita. We went and sat down on the sofa and watched the two of them cooking in the kitchen.

The drinks go down quickly, as unfortunately margaritas often do, and we get a glass of wine set in front of us. "It's not long until dinner," says Vilde. "It will be a variation of pho and some other snacks from Vietnam." The food arrives on the dining table and we move to it. While we eat, we talk about everything between heaven and earth, laugh and have a lot of fun. Just like previous dinners, we get a rare good and genuine tone. We share things we're worried about at work and how we're feeling otherwise. We simply bond more as a couple of friends.

After dinner, the four of us sit on the sofa with several drinks and a few bottles of wine. The sofa is a kind of corner sofa meets chaise longue, and we sit on either side of a table. The conversation turns to how we met our boyfriends. Kristian asks how Marthe and I met, and how we both knew we were going to be together.

"It was probably when we kissed for the first time," Marthe says. "He's a really good kisser," she says, grinning flirtatiously at me.

"What does he do that's so good, then?" asks Vilde, genuinely interested.
"It's hard to explain, but he combined the use of his lips and tongue in a good way, and he was very playful with his fingers," says Marthe, giggling. "He stroked my neck, around my ears and in the hair at the back of my head."

"You'll have to show us, master kisser!", Kristian shouts out into the room and laughs. I look at Marthe, and then I slowly move towards her. I grab her head with both arms and bring her towards me. I open my mouth and let my tongue be the first thing to meet her tongue. As we kiss intensely, I stroke her throat and neck with the fingers of one hand. I place my other hand on her hips and stroke down towards her arse, squeezing lightly. While we kiss for a period of time that was probably inappropriately long when you're visiting someone else. We pull away from each other's mouths. We both cream and adjust our clothes, before looking over at Kristian and Vilde with embarrassment.

The expression on Vilde's face is a mixture of shock and a little lust. "Damn, that was quite a show... I don't know what to say," says Vilde. Kristian's face is equally shocked.

"Why don't you try it with Vilde," I say to Kristian. "Remember that a kiss should be a pleasant mix of lips and tongue, and if you want to signal that you want something more: use your fingers on the neck and throat.

Vilde and Kristian looked at each other, and then they started kissing. I could see their tongues meet and how their lips moved towards each other. Vilde started with her fingers on Kristian's neck, and I could see that he got goosebumps. His fingers went to her neck, but I think he was inspired by me. The other hand started going down towards her hips and her arse.

Marthe looked at me with a playful look as she smiled. We also started kissing again. So here we were, well grown-up people, sitting on a sofa and making out like teenagers.

While Marthe and I were in deep kissing mode, I looked over at Kristian and Vilde. Kristian had one hand firmly placed around one of her arse cheeks, squeezing it and pressing her against him. Something came over me and I started to do the same with Marthe. I could tell by her breathing and kissing that she was enjoying it. She ran her fingers and nails on one hand around the scalp on my neck, while the other held me.

I looked over at Vilde and Kristian again, and saw that he let his fingers go from her arse to touch her tits outside her clothes. The first thing I thought was that now Kristian has gone too far, and now Vilde doesn't want any more. It's one thing to make out in front of people, but it's another to have your tits grabbed at the same time. To my great surprise, she leaned her back against the back of the sofa, which gave Kristian better access to both tits.

I'm not going to lie. I'd been hard as nails from my first kiss with Marthe, but I realised this was a new stage in my arousal. I thought I had to try it too, and I let one hand slide from her arse up to one of her tits and squeezed lightly. I knew it, of course, but I was reminded that Marthe wasn't wearing a bra. I did it with the hand I knew was visible to Kristian.

I felt Marthe press even harder against me with her mouth and kiss me more intensely. Her breathing became heavier and heavier. I leaned back in the corner of the sofa while holding Marthe against me. I did this so that I could get an even better view of Vilde and Kristian, and because I knew that Marthe's bum shape would be even more visible to Kristian. I remember seeing him looking at her when we took off our shoes. I waited until I realised that Kristian was staring at us. Then I brought one hand down to her arse, stuck it as far under the sofa as I could, took a firm grip and lifted a little as I pulled her towards me. At the same time, with the other hand I held her waist and pulled her towards me. This made Marthe's back arch and her arse stick out more. I knew that Kristian could see the shape of her arse cheeks. The tight dress did the rest.

Kristian sees me looking towards them. Vilde's dress has a v-neck that ties at the neck and he takes an extra firm grip on Vilde's chest before letting go and slipping it under the one piece that covers her breasts. I hear Vilde breathing heavily and making a small sighing sound. Kristian takes his hand out and pulls Vilde towards him so that he can get a better look at what Marthe and I are doing. He mirrors us by bringing one hand down to Vilde's bum and the other around her waist. But makes a small difference. He pulls her in such a way that she only sits on one hip. Both buttocks point towards me and Marthe. He takes a firm grip on one of them and presses Vilde against him.

I stop kissing Marthe and hold her against me while I whisper in her ear: "Are you okay?". She just says "mhm" with heavy breathing, as she strokes me through my hair and up and down my back. Through Marthe's hair, I see Vilde climbing into Kristian's lap. Marthe leans back on the sofa and looks at Kristian and Vilde, while she strokes her hand up and down my thigh. Only occasionally does she touch my hard cock, as if she wants to tease me.

Vilde and Kristian kiss intensely. Vilde's dress is short, and since she's straddling Kristian, it has slipped so high that parts of her arse and thong are showing. Kristian "helps" the dress to come a little higher, and he uses both hands on her arse. He looks at us with one eye as he does so. Marthe smiles, turns to me, and pushes me back on the sofa and straddles my lap. Her dress also jumps up quite high since she's straddling me. I take a "Kristian" and help it up a little further and let my hands fill with bum balls. Marthe is also wearing a thong. She giggles and starts kissing me.

Vilde and Kristian whisper a little together before I suddenly see Kristian stand up while holding Vilde. He carries her from their part of the sofa to our part, and sits down right next to us. She squeals playfully. I notice Marthe watching and laughing as she meets the grin on Vilde's face. Vilde leans back a little and laughs into the air with her face towards the ceiling, before leaning towards Kristian again to kiss more.

Since Kristian and Vilde took this step, I decide to test the boundaries a little more. As Marthe sits against me and we kiss, I slowly start sliding my hands up and down the zip at the back of her dress. I start to slowly pull it down from just below her neck, and down. Fiddling a bit at first because her hair is in the way. I feel every click the zip takes, and I feel the tension increase. Marthe giggles and smiles as we kiss. After about five slow clicks, I pluck up the courage and pull it down as far as I can. Then I grab each side of the dress and pull it down Marthe's arms. To my great surprise, she straightens up and pulls each arm out of the dress, folds it down over her stomach and her breasts appear in front of me.

In my peripheral vision, I see Kristian watching closely as Marthe's large breasts pop out of the garment. Marthe looks at Kristian and laughs as he does the same with Vilde's clothes, but in a too quick and clumsy way. Marthe laughs so hard that her tits bounce up and down. Vilde has to help him untie the knot because he's pulling her hair. Vilde unties the knot and pulls the top of her dress down. This is the first time I see Vilde's tits in the open. I've only seen the shape of them when she goes without a bra, but now I see the small and perfect tits with quite dark nipples and areola - but only for a few seconds before Kristian presses Vilde's tits against his face and starts sucking on them. I do the same with Marthe. Vilde and Marthe squeal and laugh.

I rub my face against Marthe's tits, and I suck and lick her nipples. I look out and see Kristian doing the same. Then I feel some hands start fiddling with my belt buckle. I push Marthe away so she has to stand up. The speed makes her tits jiggle quite a lot. I open my belt buckle and the buttons on my trousers. Marthe grabs my trouser legs and helps me. The method is unsexy, but Marthe, Kristian and Vilde laugh. I rip off my shirt, and I twist off my boxer and throw it somewhere random in the room. My cock flops out of the box, hitting my stomach on the way down to the sofa before standing straight up and pointing towards the ceiling. Marthe takes the subtle hint and kneels down between my feet, starts running her tongue up and down my shaft before licking just below the head of my penis.

Vilde weighs nothing. Kristian lifts her up and sets her on the living room table in front of him so that the wine glasses tip over. She almost falls backwards onto the table and has to support herself while laughing. Vilde laughs widely and I look straight into her knickers. A few black hairs are sticking out of the side of her knickers. Kristian wrings off all his clothes in record time and slinks off and sits back on the sofa with his cock sticking straight up. Vilde quickly gets up from the table and stands over Kristian and starts taking off her skirt and finally her thong. Marthe now takes the whole cock in her mouth and moves her head up and down, but occasionally glances over at what Kristian and Vilde are doing while laughing with her mouth full.

I've seen the shape of Vilde's tits when she's gone braless and I saw them before, but what I'm looking at now is something I'm seeing for the first time. When she takes off her thong and bends back up, I see that her ***** is unshaven. It's a perfect triangle of black hair that grows in a fairly controlled manner. The pubic hair is not frizzy, but perfectly straight. That's how it grows naturally, because I don't see any signs of her waxing or shaving. Vilde goes straight down on her knees between Kristian's thighs. She grabs his cock and brings it to her mouth, kissing it playfully and running her tongue up and down his shaft before taking the whole cock into her mouth.

As Marthe sucks me, I bend over to grab the last part of the zip on her dress. I can't quite reach, so she helps me with the last part without stopping to suck me. I pause to savour the sight of the shape of Marthe and Wilde's heart-shaped asses. Vilde's is completely naked, while Marthe still has her thong on. When I look at Wilde's butt, I can sense how the skin changes colour as it approaches the crack of her butt. From very light skin to darker. Occasionally, when she leans back to lick Kristian's balls, I get a little better idea of what's down there between the butt cheeks in the form of some black hairs that I know are sticking out from her ***** and labia - but I can't see everything I want to. I grab Marthe's head and lean down and whisper "take your knickers off" in one ear. She stands up, and bends down and pulls them off in one smooth motion with straight legs. Marthe's tits become pear-shaped as she bends forwards, and I see in my peripheral vision that Kristian is staring at Marthe. I know he would have liked to be standing behind Marthe right now to get a better view of her perfect arse and the ***** that undoubtedly sticks out between her thighs as she bends over.

Marthe takes off her knickers, poses with them, and then does something I didn't expect. She throws them at Kristian's face. She doesn't hit him, but just grazes him and the knickers land on the back of the sofa close to his head. I see that Kristian first looks quickly at what flew past his face, until he looks back at Marthe and takes in the goddess she is. Her ***** is shaved, but she has what she calls a landing strip right from around where her clitoris is and up towards her stomach. Everything else is clean-shaven. I couldn't see Vilde's labia when she stood on the sofa and took off her knickers. Kristian can see everything. Vilde looks diagonally up at Marthe and giggles. Marthe laughs and sits down on her knees again, and starts sucking me.

I can hear the sound of Vilde sucking, and how Kristian's breathing and other sounds follow suit. Vilde suddenly goes very deep on the cock, before taking it out and almost "attacking" the string under Kristian's glans. I see how Kristian's whole body is in tension every time it happens. Marthe tries it too, after seeing what Vilde does, but she doesn't get it so deep before she realises she's going to gag. But using her tongue on the string under my cockhead, she's good at that. I jerk on the sofa every time she does it, and then Marthe starts giggling.

I'm not sure how long it's been. I have my head back on the backrest and am looking at the ceiling and just enjoying it all. I feel some unfamiliar fingers on the inside of my thigh. Marthe has both hands on my thighs, so it's not her. When I bring my head down again to see what's touching my thigh, I realise that it's Vilde who has reached out a hand and is touching me. She lets her hand slide up to my balls, which she lightly caresses with her fingernails, before stroking her hand down again. She looks at me with her dark eyes while she has Kristian's **** in her mouth. Kristian sees what Vilde is doing and strokes her head tenderly. My balls tingle and shrink a little from the tickling. Marthe giggles when she sees what's happening. She moves one of her hands away, as if she wants to make it easier for Vilde to get a grip. Then she wraps her other hand around my cock as she takes it out of her mouth, and then she points it at Vilde's hand in a sort of 'here you go' gesture. Vilde touches my balls on the way up my wet shaft, and I jerk a little. Marthe lets go, and now it's just Vilde holding my cock and slowly jerking it, then she lets her hand slide over my wet glans and foreskin. Kristian's cock hasn't left Vilde's mouth while this is happening, and we have eye contact the whole time. I look quickly at Kristian. He does something that is awkward and a bit out of character for him: he gives me a thumbs up and grins stupidly.

Marthe, who is good at taking extremely subtle hints, leans over and puts her hand under Vilde's chin and grabs the lower part of Kristian's shaft while Vilde licks under the head of his cock. Vilde leans a little more towards me to get a better grip. Marthe lets her hand slide up Kristian's wet shaft and up to the glans and foreskin, where she twists it a little, before grabbing the foreskin and pulling it lightly up and down. I see how intensely Marthe is looking at Kristian's cock, before her and Vilde's eyes meet. They look at each other for a few microseconds before they start laughing. Kristian again does something that seems uncharacteristically awkward: he leans forward and touches one of Marthe's boobs and just holds it. Nothing else, like pinching her nipples or anything like that. He just holds the tit as if he's been caught doing something wrong. Marthe looks down at her tit, and then at Vilde before they both laugh.

Marthe stands up and looks round. "But... You have a great apartment, but we haven't seen where you sleep...?", Marthe says hesitantly with a wry smile and her shoulders lifted towards her head. Vilde looks surprised by the question. Suddenly she realises what Marthe means and smiles broadly. She wants us to continue this in the bedroom.

"Yes! You have to see that before you leave! I have to admit that my knees hurt now," Vilde replies with a smile. Vilde stands up and at the same time makes fake "old man noises", then she takes Kristian by the hands and pulls him off the sofa. Marthe does the same with me. We start walking towards the bedroom with the girls in front of us. I look at Kristian, who looks at me again. I don't think either he or I understand how this could happen.

"Shit! The windows!", Vilde shouts and starts running with Kristian in tow. Marthe looks over my shoulders and I turn round. The curtains weren't closed and they have neighbours. Lots of them. We also start running while laughing. The sound of bare feet and laughter fills the apartment on the way to the bedroom.

On the way to the bedroom, I caught a glimpse of Vilde's dissing arse. It wasn't as big as Marthe's, but it had a good bounce and looked firm and nice. Kristian towers over her. Marthe's arse was as it had always been: big and lovely, and with a lot of dissing that I just love. I slapped Marthe's arse lightly just before we got to the bedroom door, and she squealed and laughed. Vilde let herself fall backwards on the bed with her hands in the air, and in the light from the hallway from the bedroom door I saw how her tits dissed lightly as the bed caught her and cushioned her fall. Vilde turned over on her stomach and leaned into the centre of the bed and started rubbing herself on the bed with her bum slightly up, as if she was dancing. I can catch glimpses of parts of her ***** every time she lifts her bum a little. I got to see a little more now, but I still wanted to see more. Marthe does the same as Vilde and falls down on her back on the bed, her tits bouncing even more. They laugh as they look at each other.

Kristian switches on the light, takes out the elastic in his hair so that it falls down and starts rummaging through some drawers. Marthe sits up in bed and watches Kristian close a drawer, then turns and walks towards the bed with his cock sticking straight out. I lightly stroke Marthe up from the crack of her arse, up her back and shoulders and down towards both her tits, which I squeeze lightly. I go to another part of the bed, and let myself fall down on my back on the bed on the other side of Vilde, and try to get one of my hands to "accidentally" lay on her arse. I see how her arse squishes slightly when I hit the bed, and then when my hand hit her. I let it rest there for a bit to assess the situation. She lay still for a while, before she started play-wiggling her bum while giggling and humming something I couldn't quite get the hang of. My hand lay palm up against the ceiling, but I quickly turn it over and grab one of her bum cheeks and squeeze lightly. She keeps wiggling her bum and giggling, so I move my hand so that I can grab further in on her butt cheeks, towards her sex and bum hole. I squeeze again and she squeals lightly. I adjust my grip once more and move my fingers even closer to her ***** and arsehole. I can feel it's hot and clammy there, and my fingertips are getting wet. She looks at me and smiles, and I smile back.

"Smile," I heard Kristian say. I turned towards the sound and saw that Kristian was standing there with a hard-on but with a camera to his face. That's why he started rummaging through the drawers! He pointed the camera straight at Marthe. "Damn it, Kristian! Now you've ruined everything!", I thought. My first thought was that Marthe is probably not in favour of this. To my great surprise, I saw Marthe jump out of bed and make a face for the camera before grabbing both her tits and squeezing them together while laughing. She then turns around with her bum facing the camera, and turns back with her upper body over her bum with her finger to her mouth, pretending to look surprised. Kind of like old-fashioned pin-up shots, or Betty Boop. Her clean-shaven ***** sticks out between her thighs and bum cheeks, and Kristian takes more pictures while they both laugh. It's clear that Marthe just thinks it's fun to be photographed.

"I felt some eager movements next to me. It was Vilde who had jumped around, and was now sitting on her knees next to me quite close. Kristian pointed the camera at us, and Vilde mimicked Marthe, but Vilde's breasts were not so big that it was quite the same. While Kristian continues to take pictures, Vilde grabs my cock and grins big at the camera. She adopts several positions and different smiles, until she bends down and opens her mouth wide and sticks her tongue out and holds it close to my cock. Without touching it. On my cock, I feel the warmth of her breath. Kristian moves closer and takes lots of pictures of Vilde's face and my cock from different angles.

Marthe laughs and draws closer and closer to Kristian. Finally, she stands right next to Kristian, and holds him while he takes pictures. Vilde is still holding my cock, and is quite close with her mouth. Then she makes a kissing motion while holding it in front of her face, pretending to look at it in shock. Kristian's cock was still hard, and I could now see that it was dripping a little - he was ready for more, I thought. It reminded me that I had felt Vilde was wet, as I brought my fingers in at her ***** and arsehole. I again lead my hand back to Vilde's arse, and began to knead and explore. Feeling her stiff pubic hair, and I got to feel some of her soft labia. Vilde now starts to play-kiss my cock with loud smacking sounds, while making small movements with her arse. I look over at Marthe and Kristian. She has her hand around his cock as she slowly moves the foreskin back and forth, feeling the wetness coming out of his cockhead.

Marthe suddenly says very seriously: "I think we all might know where this is going. Is that okay with you?". That last bit was directed at me. I just looked at Marthe with wide eyes while she still has Kristian's cock in her hand, and said: "mhm!". Vilde had frozen in the middle of a play kiss when Marthe said what she said, and she made big eyes as she looked at each of us. Kristian asked Vilde: "What are you thinking?" Vilde laughed and answered by licking my cock from root to glans and then taking it into her mouth and out with a distinct "pop" as she looked at Kristian. Kristian says, while laughing: "I'll take that hint!". Everyone laughs. Kristian jumps onto the bed next to Vilde. Marthe also jumps into bed next to me.

Marthe lay on her back, and I lay next to her and kissed her neck, around her ear, and then down her neck again. All the time I had a hand on one of her tits, and pinched her nipples lightly. Her big tits spread out to either side, and I watched them jiggle every time Marthe got a hard-on. I started moving my hand down from her tits and stomach towards her *****. She was as wet as Vilde. She sighed lightly when I grabbed her *****, and started moving my fingers around her lips before I worked my way up to her clitoris. Behind me were Kristian and Vilde. I took a quick break from sucking Marthe's earlobes and looked behind me. Vilde and Kristian were doing the same as us. I saw Kristian sucking Vilde's nipples while he had his hand firmly planted in her sex. Vilde lay there with her eyes closed, making little noises and yelping every time it tingled in a good way. I want to experience this, I thought, and quickly jumped to the other side of Marthe, who started laughing at how acrobatic a 40-year-old suddenly became. I continued rubbing her clitoris and kissing her neck and ears.

I looked over at Vilde and Kristian again, and now saw that Vilde had her eyes open and was looking towards us. Kristian did the same as he sucked on her nipples. Kristian had now gone from lightly massaging her ***** to inserting his fingers. I could tell by the angle of his hand, and how Wilde's face changed emotions as he moved his hand and did things with his fingers. I could also hear wet sounds every time Kristian increased the pace. Her tit, which was facing us, dissed lightly as Kristian fingered her hard.

Now I wanted to taste Marthe. I took my hand from her ***** and rubbed her juices against each nipple before licking them clean. Marthe laughed and lifted her head up to look: "What are you doing?!" After getting a taste of her juices I had smeared on her nipples, I moved from her tits, down her stomach and then to her sex. I lifted both thighs up so that I could get a good grip, and then I started kissing the inside of her thighs. It obviously tickled Marthe, she wriggled and giggled, but there was only a deep sigh when I went all in towards her clitoris with my whole mouth. I know Marthe well, and I know she likes it best when I use a flat tongue against her clitoris with my whole mouth. I therefore took a firm grip on her hips and started licking and nibbling. Marthe gradually went from small sighs to making some small noises. She has never been one to make a lot of noise, but I know her sounds well.

With my eyes closed, I worked on Marthe's clitoris, and I felt her hips start to move more and more. Suddenly I felt someone sit on my back. It was Vilde. I paused for breath and asked what she was doing, laughing. "Taking pictures of Marthe and my Kristian," she said with a smile. I went down to Marthe's clitoris again, but this time I looked up. I saw Marthe's tits as she twitched. From one side I see Kristian leaning towards Marthe's face. They kiss heavily a few times, and I see that they share heavy breathing with each other as he strokes her forehead and hair. They kiss again, and I see Kristian whisper something to Marthe and she opens her eyes and looks at him and nods. They kiss again and Kristian grabs her first on one boob, brushes his hand against the other boob and squeezes lightly. Kristian kisses Marthe playfully on the nose, and she smiles. Then he sits up and leans forwards so that his cock moves towards her mouth. The sight of Marthe actually reaching for his cock, leaning towards it to receive it, makes me extra horny. She grabs it to make it fit better in her mouth. Horny juices drip from Kristian's cock onto Marthe's forearm, and I see it glistening in the light from the ceiling. Marthe pulls the foreskin back slightly and twirls her tongue around the tip of the cock a little before it slides slowly into her mouth, between her lips.

As I lick Marthe, my beautiful girlfriend, I see from up from her sex and the landing strip, up between her big and dissing tits, that she is sucking a man other than me. He slides in and out of her mouth, supporting himself with one arm beside her. I watch as she alternates between sticking her tongue out while sucking and taking it out, pulling back the foreskin and using her tongue on the cockhead. Kristian only supports himself on one arm, and uses the other to touch both her breasts and pinch her nipples. I hear camera clicks above me. Vilde is taking pictures of her boyfriend being sucked by another woman. She quickly strokes my hair and jumps off. She walks over to Marthe, who takes Kristian's cock out of her mouth to whisper something to Vilde, who whispers something back again before they both giggle lightly. Vilde and Kristian kiss deeply as Marthe takes his cock in her mouth again, and Kristian takes a firm grip on one of Marte's tits before touching one of Vilde's tits and pinching her nipples. I see how Marthe uses her tongue as she sucks. Vilde and Kristian whisper a few words to each other before kissing some more. Then Vilde takes a few more pictures of Marthe sucking Kristian before she walks behind me.

Vilde grabs me and pulls me off Marthe and onto her side of the bed. She kisses me on the mouth, and then she turns on her stomach and pulls me towards her. I see that Marthe is now on her knees in the bed while Kristian lies down on his back in front of her, but with his head right under her *****. Marthe straddles his head, sits down, grabs his cock and pulls his foreskin back and continues to suck him. Kristian starts licking her while keeping a firm grip on Marthe's big arse. Vilde lies in front of him on her stomach, and removes the hair from her neck. I take the hint and start kissing her neck. She lifts her arse up so that she teases my cock with it. As I kiss her neck and suck on her earlobes, she sighs heavily and moves her arse. As she lifts her arse up, I feel one of her hands grab my cock and push it in between her butt cheeks. I feel her tighten around it, and use her hand to position it straight. Between her bum cheeks, it's wet and warm. I moan lightly as it happens, and Vilde giggles and grins as I continue to suck on her earlobes. While she has my cock between her butt cheeks, she moves her arse up and down and jerks me off. On the way up she doesn't tighten, but on the way down I feel her tighten. It's the first time I've been wanked like this before. It's hot, smooth and incredibly wonderful and I can feel the head of my cock touching her labia and her stiff pubic hair. I smell her hair on the head as she jerks me off, and I breathe in her heavy breathing and lick her ear. She starts to speed up a lot, and I have to pull out from her wet arse cheeks before it goes for me. Her skin glistens in the wetness as I look down at Vilde's arse.

I think Kristian was also realising that his orgasm was too close. He has put Marthe back on her back again, and is between her thighs. He's seen what I've done to Marthe and has decided to copy me. I see Marthe's tits jiggle every time he hits something that feels good. Vilde gets up on her knees and takes close-ups of Kristian. I take the camera from her and force her down on her stomach. She squeals and laughs. I hold her hands firmly on her back and press my face between her buttocks, and use my tongue on her arsehole and *****. She howls, laughs, and moves, but I hold her down firmly and decisively. I let my nose press against her arsehole as I lick and suck on her labia. Marthe has realised the commotion and has lifted her head and is laughing. She sees the camera and takes pictures of me and Vilde. Kristian laughs too, but it's a subdued laugh as his mouth is full of Marthe's clitoris. I keep on working, and Vilde eventually calms down and starts making heavy sighing sounds, moaning and breathing heavily. I keep her hands firmly on her back, and I alternate from licking her ***** to licking in and around Vilde's arsehole. It tastes different from Marthe. Vilde is a little less salty. I let go of Vilde's hands and she stretches them out and puts her head on them. I look up at Marthe, who still has Kristian between her thighs. She has the camera in her hands, and occasionally takes a picture of Kristian as he goes down on her.

Marthe strokes Kristian's hair while he licks her assiduously, and she lets out quiet little moans every time I see a thrill go through her body. She now looks at Vilde, who is breathing heavily and making more noise than before. Marthe reaches out her hand and strokes Vilde's face, and from between Vilde's buttocks I see Vilde turn her head towards Marthe and search for her hand. Marthe's face alternates between pleasure and smile as she looks at Vilde, and I assume Vilde does the same. On pure impulse, I grab Vilde's back and signal for her to turn more towards Marthe. She twists at my command. The camera is in the way between them, so I take it and move it to the other side. Then I signal again for her to lean forwards towards Marthe. Vilde moves a little more forwards. I give the signal again, but when Vilde strokes forward I press my face against her bum so that she has to take two strokes forward. Marthe and Vilde are now close enough to share the same breath, and they look at each other and smile. Marthe strokes Vilde's face again.

As they breathe heavily together, Marthe, with Kristian between her thighs, and Vilde, with my tongue and nose between her arse cheeks, I see that they share a kiss. First a small kiss, but repeated several times before they share a deep kiss together, and I see their tongues meet. I fumble for the camera, and manage to get a few shots of it as I press my nose down against Wilde's arsehole, and lick and suck on her labia. It's the first time I see my girlfriend kissing another woman. I see Martha's hand slide under Vilde's torso, which lifts up so Marthe can grab one of Vilde's perfect little tits. Vilde kisses Marthe deep and long, before moving her head down towards her tits, grabbing them with one hand and starting to suck and lick around the nipple. Kristian looks up from Marthe's *****, and I see him smile and glance over at me quickly. I take a few pictures of Vilde and Marte making out, and Vilde sucking and touching Marthe's tits before I put the camera down to concentrate better. Vilde is now resting her forehead against Marthe's forehead, and Marthe sighs deeply. Suddenly I feel some fingers that are down my mouth by Vilde's *****. It's Marthe's fingers that are exploring. I take one of them in my mouth to signal that I know what she's doing. She strokes my chin. Like the kiss earlier, this is the first time I've experienced Marthe touching another girl's *****. I alternate between licking Vilde's arsehole and labia combined with Marthe's fingers. I feel that Marthe has a finger between her labia and rubs them against her clitoris.

Vilde moans lightly and starts moving her hips and rubbing against my tongue on her clit. I pull my face out quickly, lift her up by her hips, give her a good slap on one bum cheek before grabbing my cock and putting the tip against her ***** just after she gets on all fours. She squeals when I slap her, but it quickly turns into a moan as I penetrate her. Marthe looks at us in surprise, but she's taken aback when Kristian finishes his licking just as quickly, almost jumping up on his knees and lifting her feet backwards and up in the air and out to either side. She squeals and laughs, holding on to the bed cover. He takes his knees far out to the sides, and eels in towards her sex with his cock like a homing missile. I watch it move from side to side as he eels closer. He leans on one of Marthe's thighs, while his other hand grabs his cock. I watch wide-eyed as he pulls the foreskin back a little before lightly touching her labia with the head of his cock, feeling for a bit where it's right before pushing the first cock after mine slowly into my girlfriend's shaved *****. Marthe puts her head back and moans quietly and I see her body twitch as Kristian presses the cock head between her labia, and into Marthe. I think Kristian was ready too, and just needed confirmation from someone else about what was going to happen next. After I put my cock inside his girlfriend, he became a man with a goal!

Now I get my wish from the moment I saw Vilde take off her thong. I see her perfect heart-shaped arse, her butthole and her *****. The skin changes colour slightly from the light brown butt cheeks to slightly darker skin towards the butthole, which is completely free of hair even though Vilde is otherwise untrimmed. I take a hand and place it on Vilde's back, and she arch her back even more. This makes her arse even more heart-shaped, and the labia around my cock become more visible to me. I put a little pressure on my arsehole with my thumb, and Vilde sighs heavily. As my glistening cock slides in and out of Vilde's *****, I can't help but watch and enjoy the sight. This is the first girl I've had sex with since I got together with Marthe - and for Marthe, it's the first boy she's had sex with since we got together. I alternate between watching myself sliding in and out of Vilde, grabbing her bum cheeks and squeezing and using my thumb against her arsehole, to watching Kristian sliding in and out of Marthe. I pick up the camera and take pictures straight from above of Vilde's perfect heart-shaped arse as I slide in and out of her *****. I take a few shots vertically so I get the whole hourglass shape of Vilde, from her arse to the back of her head, and how my **** slides in and out of her *****. Then I point the camera at Marthe and Kristian.

Kristian stops a bit and takes a few deep thrusts towards Marthe, and I see how her face changes to pleasure when he thrusts. Her tits are bouncing extra hard. She has her hands around her thighs close to his knees, and I see her sort of pull him towards her when he thrusts hard and there are distinctive slapping sounds. He leans forward and kisses Marthe intensely and long, before working his way down her neck and tits - all the time moving slowly but firmly in and out of Marthe. Hearing her breathing heavily and making little noises especially then grabbing both her tits, pressing them together and sucking on both her nipples at the same time as he drives his cock in and out of her *****. With one hand on Vilde's brown heart-shaped arse, I lean back a little to try and see between Kristian and Marthe's legs, and catch a small glimpse of his cock parting her clean-shaven labia, part of her arse, and his cock wet and shiny as it goes in and out of her all the way down to her balls. Marthe's wet arsehole occasionally contracts and twitches. I try to take some pictures of what I see, but the angle is a bit weird so I reach out my hand with the camera and take a few pictures blindly before giving up. Marthe signals to me that she wants the camera again. She takes pictures of Kristian while he fucks her. I see her bring the camera down towards her ***** to take pictures of his **** sliding in and out of her ***** from where her landing strip starts.

Vilde falls forwards, causing my cock to fall out of her, and she throws herself down on her stomach and turns round quickly. She lifts and spreads her thighs and looks me in the eye. I adjust myself down so that I'm in the same position as Kristian, with my knees out to the side, and I move towards her *****, aiming my cock straight at the target. Her ***** is covered in hair, but I can see through the hair where it's wet. There's a glistening on the sides of her thighs. I grab one of her thighs and push her back to lift her arse up, and I grab my cock, pull the foreskin back a little and feel for where it naturally slides in easily. I hear the camera clicking a lot, and see Kristian taking pictures of another man about to penetrate his girlfriend. Through Marthe's light moaning, I hear Vilde sigh deeply as I push the cockhead in, wait a bit and then push it all the way in. I quickly adjust myself and put my other hand on Vilde's thighs and lean on them as I start moving my hips. I look down as my cock slides in and out of her hairy *****. Her brown and perfectly shaped tits are squeezed between her thighs, yet I see them move when I thrust. I hear her breathing change as I thrust and pick up the pace, and she has her head up off the mattress as if to meet my face and get closer as she holds me around my thighs and knees and pulls me towards her. She furrows her eyebrows and looks at me intently. Her wild black Asian hair spreads out behind her on the mattress.

Marthe and Kristian are lying face to face while Kristian fucks her rhythmically, and occasionally there are slapping sounds when their bodies meet. Marthe has both hands on Kristian's arse and I see her grab and almost push him when he thrusts in. They kiss deeply and intensely, and go back to sharing their breath again by pressing their foreheads together. Kristian picks up the pace, and so does their breathing. I hear how Marthe's breathing is characterised by Kristian increasing the pace and intensity. She takes one hand from his arse and holds it to his face, and she says something I can't hear. He nods and looks at her. Marthe, smiling and moaning softly, takes her hands and holds them around his shoulders and pulls him close.

Vilde pulls me towards her and kisses me deeply. She holds me in the crook of her neck as I move my hips and I slide out of her. In my ear I hear her breathing heavily and moaning quietly. I move my head down to her tits, touching them and feeling what they actually feel like. They're not as big as Marthe's, but they're incredibly beautiful. I suck on her dark nipples and run my tongue around her areolas before switching tits and repeating the action several times. I move my head up and meet her mouth again and we kiss deeply. She whispers something, almost into my mouth with her breath: "I'm coming soon. Are you coming?". "Soon," I say, increasing the pace firmly. I straighten my back again so I can push even harder and see Vilde better. She looks deep into my eyes while her mouth is open and I hear her moaning quietly.

Next to me I hear familiar sounds from Marthe. Marthe holds Kristian close to her, and I can almost see how her fingers and nails make red marks on his back. Kristian has really picked up the pace and together with the deeper and faster sounds Marthe is making, I know that they are both coming soon. Kristian increases the pace so that the slapping sounds become louder. He holds both hands around the side of Marthe's head, and I can see he's pushing hard with his whole body. Marthe starts to make deep moans, and I see how her toes curl and straighten out. I lean back a little to look between Marthe and Kristian's thighs again, and where the ***** and cock meet. Kristian's cock goes in and out of her ***** quickly, and I see her labia join in with Kristian's cock. His balls occasionally hit Marthe's arsehole, which has now become a little wetter since I last saw it. Marthe is squeezing her arsehole more rhythmically now, and I see her occasionally lift her hips up which makes me see the shape of her arse better.

Vilde starts making louder noises, and I look away from Marthe and Kristian and down at Vilde. She looks at them before looking at me. I speed up and there are slapping sounds. Her tits move up and down in rhythm. She moves her mouth: "Are you coming?" I nod and see that Vilde closes her eyes and tightens the muscles in her body. With my hands, I grab Vilde's breasts firmly, using them as handles to grip even harder when I thrust. I can feel her ***** contracting and the twitching coming. I speed up even more because I'm also close to orgasm. I hear the sound of Marthe, with her deep but quiet throaty moans as she comes and the contractions happen. I hear Kristian moaning lightly and the pace of his hips slowing down as he comes inside her. Vilde lets out a loud and short squeal, jerks again, and her ***** grips my cock and her hips move. I tighten my lower abdominal muscles and hold my breath to be able to hold back and have a more powerful orgasm. Holding it for as long as I can. I moan deeply as I come in Vilde's *****, and I slow down to ride the pulsations of my orgasm - slower and slower, until I stop and lie down on Vilde and breathe. From her breasts, I see how Marthe and Kristian are lying in the same position as us and just breathing. Kristian lifts his head and looks at Marthe, and makes a face. Marthe starts laughing as she covers her mouth. Kristian chuckles. I look at Vilde and we laugh.

I slowly pull out of Vilde and lie down next to her on my back. My cock is still a little stiff, but it slowly becomes more and more flaccid. Vilde quickly jumps out of bed and runs to the bathroom and disappears for a little while. Neither of us say anything. We just lie there and breathe, while I look at Marthe and Kristian who are still holding each other. Kristian straightens up a little, and he holds his cock as he slowly pulls out of Marthe's ***** and lies on his back next to her, and I hear them whisper something I can't make out. Kristian's cock is pulsating as it gets looser and looser. They giggle and kiss deeply several times. I start thinking that this is the first time I've come in any other girl than Marthe, and that it's the first time a man other than me has come in Marthe. Vilde returns from the bathroom with towels, which she gives to Marthe. She lifts one thigh and dries herself downstairs, and gets up to go to the bathroom too. Vilde comes first to give me a deep kiss before she goes and lies down next to Kristian, they kiss and whisper together until Marthe returns from the bathroom. She stands in the centre of the doorway and looks at us. The light from the corridor frames her figure nicely, and she holds her hands on both door frames. She looks at me and smiles.

"What do we do now, then?", I say without actually directing the question to anyone. There's silence for a few seconds before Marthe says, in the sound of northern Norwegian: "I don't know about you, but I'm hungry as hell!" Everyone laughs. "There's plenty of food left," says Vilde and jumps out of bed with Kristian. We follow. I hold Marthe's hand as we walk. Suddenly Vilde shouts: "Noooo! The windows!", she moves back to the corridor and hides behind Kristian, who looks a little frightened. I wrap my hand around my **** and balls and run into the living room towards the windows, stop and wave in a stupid way, before closing the curtains. Everyone else laughs out loud.

Vilde and Kristian start to take out of the fridge and heat up pho, some meatballs and spring rolls. Everyone is still naked. Marthe and I sit down at the dining table. I reach out a hand to Marthe, and she grabs it and squeezes it. I say quietly with my mouth: "I love you". She replies back with her mouth: "I love you too". After we ate a little, we went to sleep - they in their bedroom, while Marthe and I took the guest room. The next day we woke up quite late, and had some breakfast we ordered via home delivery, and then we took the train home.

The following Monday, around lunchtime, I was contacted by Kristian who asked if I had Signal. I said yes and gave him my phone number. Shortly afterwards, I was sent photos from the weekend's festivities. There were pictures of Marthe's imitation of Betty Boop with her ***** clearly visible between her arse cheeks and thighs, of Vilde on her knees posing with my cock, of Marthe lying on her back being licked by me while she sucks Kristian's cock and he pinches one of her nipples, of me with my head deep between Vilde's arse cheeks where Vilde's face is a mixture of laughter and pleasure, some pictures of Kristian and Marthe where one was of them in 69 and the other is from when I took pictures between Kristian's thighs of his cock going into the ***** just above Marthe's arsehole, then two pictures at the end where I take Vilde from behind and the moment I penetrate Vilde in missionary while she lifts her head up and looks at me intensely. Just after the pictures, a message comes in: "Hope you won't be offended that Vilde and I have looked at the pictures often, and that we make love while doing so?" Before I have time to reply, another message arrives: "Vilde has spoken to Marthe today at work. They agree that we should have dinner together soon!"

I replied: "We have another couple of friends in the neighbouring apartment, maybe we can invite them over for dinner?" Kristian sent back five or six emojis, which reminded me of when we were on the sofa with the girls between our legs. There were five or six big thumbs up.
