First Time Sharing My Girlfriend[FMM][Cuck][Accidental sex]

(Everything below is a work of fiction)

“We brought rum,” said Emma, as her friend James opened the door. Emma was my girlfriend of the last year. We met online, and had a long distance relationship with the consent of her parents. I was in town visiting for a week, her mom even let me stay in her room. “You remember I told you about my boyfriend, Andrew.”

“Yeah, how’s it going?” James asked me. James was a thin guy, a bit dorky, and shorter than me. I could tell why Emma thought he was kind of cute. They had been friends for a couple of years, and he definitely had a crush on her.

“Pretty damn good,” I say, flashing a smile at Emma.

James let us in, and walked us up to his room. Our original intent was just to stop by and buy some weed. However, his dad was gone for the weekend, so we figured it would be a good place to drink a bit. We didn’t think her parents would appreciate the drinking.

James’ bedroom was what you would expect from a guy his age. He had a twin size bed with basketballs and baseballs on it. He had a big desm with a nice gaming computer. I assumed he streamed, based on seeing multiple cameras at the desk. There was a bookshelf with some old action figures, and a television with a video game console.

James took a seat in his desk chair, Emma climbed into his bed and crossed her legs. I sat on the edge if the bed, and we toasted to parents not finding out.

It was a fun night, we laughed and joked as we drank and smoked weed. We were definitely spending the night, so Emma changed into a pair of purple pajama pants, and a little blue tank top. I could tell she went without a bra. Her long brownish blonde hair was down, but she had a few hair ties around her wrist. James and I were both wearing ball shorts, mine white, his black. I had on a comfortable blue t-shirt, and he wore a baseball t-shirt, I assumed his favorite team.

Over the night I noticed the way James looked at Emma. I couldn’t blame him. She was adorably cute, bouncy and optimistic. She had a tight body, stood about 5’8″, and the perkiest tits you ever saw. When she leaned forward a bit on the bed, I could tell James was looking down her tanktop.

I didn’t expect it, but seeing that made me get a bit hard. That’s when I first had the idea, but I had no idea how to act on it. I went back and forth in my mind about it, but the more I thought about it, the harder I got. I kept having to try and hide by boner in my shorts.

We had talked about threesomes before. Of course, I wanted to have a three way with another chick. Like a lot of guys, I hadn’t been too hot on the idea of involving another guy. Maybe it was the alcohol… but tonight I was being turned on by the idea. If we did it, she would have to let us do it with another girl.

“Isn’t that the chair you said would be perfect for having sex in?” I asked Emma, and looked over to James, sitting in said chair.

“Yeah,” Emma giggled and nodded. “A girl’s legs could easily fit between the back and the arm rests.”

I noticed James blush.

“I dunno,” I say, feigning skepticism. “I don’t see it. Sit on his lap and show me.”

James’ eyes went wide, and I looked over at Emma. She was a bit of a free spirit and definitely got horny when drunk. She stood up, grinning and walked over to James.

“Are you sure?” He asked, looking up at my girlfriend.

“We aren’t naked,” she said, with a shrug. She walked up to hin sitting down and put a hand on his shoulder. She awkwardly lifted one leg and put it over him. Then she lifted her other leg, standing up over him for a moment. His face was just inches away from her tits, and he was staring at them through the blue tanktop.

My boner twitched and she slowly sat down on his lap, facing him. I watched as they looked into each other’s eyes for a moment, before giggling.

“See?” She said, looking over at me and wiggling her hips. “There it is,” she said with a grin, realizing she must be sitting right on his boner. I wondered how big or small he was.

“I mean, you can sit on him sure,” I say, shaking my head. “But I can’t tell if you can really do it at the angle. Take your pants off and try it again.”

Emma grinned at me, and didn’t hesitate to climb back off. James was wide eyed and speechless, watching her every move. Emma stood up, turned her back to James and bent down, pushing her pajama pants down. She had on a tight pair of pink boy short panties on. I watched as James stared at her ass, before she turned around and he stared between her legs.

There was precum leaking in my boxers, I imagined just the same for James.

“James, wanna be a bud and take off your shorts?” I asked, hoping he wasn’t too weirded out by the situation. “For scientific purposes, clearly.”

“Y-yeah, sure thing,” he said, and I saw a spark of eagerness in his eyes. He was definitely cool with this. He stayed in the chair, pushing down his ball shorts. He had on a pair of baby blue boxers, and I could see his erection making a noticeable tent.

Emma say it too, as I caught her looking down at it she then sat back down on him, just as before. I could see a little blush on her cheeks as she sat right down on the tent.

“Hey there,” she said to James, giggling as she wiggled her hips a bit. I wonder if she was getting wet yet. James giggled too, also blushing.

“I dunno,” I say, leaning forward a bit, and tapping a finger to my chin. “Bounce up and down, like you were doing it.”

Emma didn’t even look back at me as I spoke, nor did James. Their eyes were locked, and as instructed, she started bouncing on his boner. I watched with great intensity, and my own boner throbs. I reach a hand into my shorts, and squeeze it.

I watch her do it for a moment, James starting to make little moaning noises.

“I’m still not sure,” I say, squeezing my cock one more time before pulling my hand out. “I mean, as long as you guys are wearing underwear, I don’t think we will know for sure. Wanna just take them off?”

Again, neither of them looked back at me. Emma shrugged, but couldn’t keep herself from blushing and grinning.

“Definitely,” James said, almost as if in a trance. Emma cimbed back off him, and felt nice enough to go first. She hooked her thumbs into her panties, and pulled them down. She used a foot to fling the panties at me.

I caught them with one hand, and held them.

James was staring between her legs, and Emma just stood there and let him. She was shaved amazingly smooth, my visit definitely had sex planned. Sex with another guy… was terribly unplanned.

James finally shook his head, and stayed sitting while pushing down his boxers. His boner flopped out, super hard. Emma stared at it. He was about 4″, I guessed, nothing huge. It was a little thick though, circumsized. Just a little smaller than my own.

“Okay, so how should we do this?” Emma asked, stepping back up to James.

“Sit on it, just like before,” I said. My eyes watched intently as she did just that. I could see the lips of her young pussy sit right on the shaft of his cock.

They both sighed in unison. She had to be wet, she was way too into this. She didn’t wait for me to instruct her before she started wiggling her hips and bouncing on it.

They were so close…

“Wait…” I say, standing up from the bed and walking over. I knelt down behind and beside the chair. I smiled up at Emma, and then down toward her hips. I saw her pussy sitting right on his shaft, and saw precum leaking from the tip. “Raise up a bit, sweetie,” I say to Emma, smiling. “If you were having sex, his cock would he standing up.”

She raised her hips up off of him, and his boner sprung up. It was almost as if it was reaching to be inside her. I could see her pussy, definitely wet. Emma had only had sex with me, and with our infrequent visits, she was still extremely tight.

“It might actually work,” I say, smiling. “Touch the tip of his dick to your pussy.”

The tension in the air was crazy. I watched, just a foot away, as she lowered her hips a bit. Her right hand came down, and the tips of her fingers gently touched the tip to the entrance of her pussy. She was so wet.

No one said anything, as she held it there for a moment. James was breathing a bit heavy, more precum leaking from his cock as he stared at Emma.

Emma stared back at him, her nipples now quite poking through her tanktop. Her fingers would twitch a bit, rubbing the tip of his cock against her pussy. I saw the head of his cock pressing into the entrance.

Still, no one said anything. No one mentioned that he wasn’t wearing a condom, though I knew she was on reliable birth control.

What happened next was almost inexplicable. Perhaps it was divine intervention, if you believe in that sort of thing. I sat there and watched as my beautiful girlfriend teased the head if another guy’s cock against her pussy, and the the chair’s hydraulic height gave a little.

The chair suddenly slumped straight down, maybe only an inch. Emily gasped as she fell forward a bit. Her chest pressed against James’, and there faces almost smack into each other. James’ groaned, as he felt the entirety of his cock slip into Emma’s pussy.

My eyes were wide.

“That was an accident!” Emma said, looking at James and then at me. James said nothing, but his face was that of a newly non-virgin young guy.

“Well,” I say, heart racing and precum leaking into my boxers. I can’t help myself, I push down my boxers and free my cock. My right hand squeezes around it, and I start stroking slowly. “It’s already in, might as well run the full experiment.”

Emma grinned at my, and looked back at James. They stared at each other for a moment, his cock deep inside her. She puts a hand on each of his shoulders, and starts to wiggle her hips.

James groans, and I’m am just here for the show.

All three of us gasp a little when she starts bouncing her hips up and down. James has no idea what to do with his hands, both of them just holding on to the armrests. Emma finds a rythym, and before long she is properly fucking her virgin friend in his desk chair, as I stroke myself just a few feet away.

I’m watching with baited breath, as Emma starts to moan a bit. Suddenly, I see James tense up a bit, and lets out a long groan. Emma comes to a slow stop, and let’s his dick rest inside her.

“He just came in me,” Emma say, looking at me and giggling.

“Holy shit,” James and I say in unison.

Emma slowly climbed off him, and looked down at me. I stood up, pushing my shorts and boxers off, and taking off my short. Emma took her shirt off too, and we crawled into James’ bed.

He sat there and watched as we fucked right in front of him.
