Warning this series is fundamentally a bisexual (MMF) threesome story. If bisexuality makes you feel uncomfortable, you should probably stop reading now. Also, I have illustrated versions of these stories in PDF format for anyone who would like a visual to go along with the words. I hope you enjoy. M

I walked down the hall and into our room and just stood there. A part of me wanted to just run away, to walk into the night. While another part of me wanted desperately to pull my cock out and finish jerking off. How the hell this could have happened?

His name was David. We worked together via phone and email for the last year, but up until this afternoon, we had never met in person. When I heard he was coming to town, I invited home for dinner to meet my wife, Carol.

Looking back, the evening had all seemed unremarkable. Everyone hit it off well, but if there was some flirtatious chemistry between the two of them, I missed it completely. We mostly talked about work and politics and baseball. We grilled out on the patio. It was hot as hell, so after dinner I loaned David a set trunks, we went swimming, and had a few frozen drinks.

After an hour or so, Carol went in to make another batch of margaritas and David excused himself to use the rest room. When some time passed and neither of them returned, I went looking for them. Now, barely a half hour later, my wife was bent over the bathroom counter, cooing like a kitten, while David's cum was slowing dripping out of her pussy and down her leg.

I was shaking and a little dizzy. I sat on the edge of the bed; my mind flooded with thoughts and emotions. The word "cuckold " felt like a rock pressing against my chest. I could hear movement in the other room. I knew I would have to confront Carol, but I was hoping that David would be gone. With luck, I'd never have to face him again.

After a few minutes there was a light knocking at the partially opened door. I looked up to see David, dressed once more in my swimming trunks. "Paul? Paul, I'm so sorry. I don't know what happened."

"You just fucked the hell out of my wife is what happened!" My voice was sharp and cutting, but the truth was I didn't know how I felt. Standing, I looked past him. "Where's Carol?"

"She's taking a shower." David stepped into the room, closing the door behind him. "Listen, Paul, she doesn't know you saw us. She doesn't ever have to know if you don't want her too."

"Like that's going to change anything! What I don't get is how the hell it happened! Did I miss something? Did you two have something going on the side I don't know about!?"

"No! No... it's not like that." David blushed and looked down at the floor. "Look, I know it's no excuse, but I've been so horny lately and your wife looked so damn good in that bathing suit..."

"So, what? You decided to seduce her?'

"That's not what happened."

"So what did happen?"

"I... uh..." He took a deep breath and blurted out, "I was jerking off in your bathroom and she walked in on me." His face was crimson red.

"What the fuck! You were jerking off in my bathroom and what? She decided to give you a hand?"

"God, Paul, I don't know what to say." He seemed genuinely flustered. "Believe me, it's not her fault. She didn't know I was in there. I was standing at the sink and she practically walked right into me. And, it just... just kind of happened." He seemed at a loss for words and fell silent waiting for me to respond.

"Happened how?"

"Do you really want to hear this?"

My voice was barely above a whisper. "Yes."

He paused for a minute, seemingly searching for words. "At first we just stood there. She caught me in mid-stroke. I was so close to cumming when she walked in I just kind of froze. I didn't know what to do. Here I was jerking off, thinking about you guys and suddenly she was there, standing so close my cock was practically touching her."

He paused, and, without thinking, I looked down at the outline of his semi-hard cock beginning to stir in his swim trunks. 'Jesus,' I thought. He's getting a hard on just telling me about it.

"Go on. What happened next?"

"Like I said, at first we just stood there like two deer caught in a headlight. She gave a little startled cry and put her hands up as if she was going to turn and run away, but instead she just stood there looking down at my cock. She looked kind of stunned and everything got real quiet."

"Honest to God, Paul, I don't know what possessed me. I should have just left, but instead... I... uh... I took her hand and placed on my cock. Even then she didn't move. She just stood there with my cock throbbing in her hand... and then I kissed her."

"At first it was all one way, but after a minute she started sucking my tongue into her mouth and she brought her other hand up to my cock and began to stroke me. I know you don't want to hear this, but it was one of the hottest moments of my life. I damn near came right there in her hands."

But he was wrong. I was dying to hear it. I needed to hear it. My heart was pounding in my chest. His eyes left mine and looked down to where I was unconsciously rubbing my cock through my trunks. I felt a flush of embarrassment, but his voice relaxed a little and he moved closer. Embarrassment gave way to a rush of excitement as he openly started rubbing himself and continued to talk.

"After that, I couldn't stop if I wanted to. I didn't think about you, or where I was, or what we were doing. All I could think about was getting my cock into her. It was like someone flipped a switch and, for a minute, the world just went crazy. I slipped her swim suite off her shoulders. She hesitated for just for a moment and I panicked. I thought, 'Oh God, she's going to stop me and scream rape or something.' But then, I cupped her breast and started sucking on her nipples and she just kind of melted."

I closed my eyes and pictured it in my mind, Carol's reluctance slipping way as his tongue played across her nipples and she stroked his cock.

I knew how excited she gets having her nipples sucked and could well imagine the thrill of having a strange man and strange cock added to the mix.

"I know I'm not telling you anything you don't already know, but your wife is fucking beautiful, Paul. You must love playing with those beautiful tits and the way her nipples get so long and hard when she's excited. When I pulled her bottoms off to reveal her pussy, she was sopping wet. And when I slid my fingers down to her pussy, she spread her legs and humped against my hand, the whole time kissing me and moaning into my mouth. That's when she came the first time."

A small moan escaped my lips when he said that. The truth was I loved the idea of her so excited... spreading herself for him... cumming on his fingers.

I sensed a change in his voice and opened my eyes to find him standing barely a step away. The outline of his hard cock was clearly visible through his trunks. Our eyes met and his voice took on a faraway quality as if he was reliving events as he told them.

"I think a part of her came to her senses a bit after that. Where everything was in a kind of slow motion up to that point, suddenly she seemed rushed. Before I realized what was happening, she pushed me back against the counter, dropped to her knees and slid my whole cock into her mouth. God, it felt wonderful. And looked wonderful.... her looking up at me, sucking my cock. I never felt so big... and there she was taking my cock all the way down to the balls."

"Her hair was still wet from swimming and I put my hands on either side of her head. I wanted her to stop, but she just bobbed her head and started fucking my cock with her mouth. I told her she was going to make me cum, but she just moaned and slid her hand between my legs and played with my balls. I could see she was fingering her pussy the whole time."

He closed his eyes and I watched as he reached into his trunks and took out his cock. It was 7" , circumcised and still wet with a mixture of their cum. While no longer than mine, it was thicker and somehow heftier looking. His pubic hair was neatly trimmed and his balls swung heavily as he stroked himself.

I had never seen another man like this before. The sight of his cock had me swooning with excitement. I didn't know what was going to happen, but whatever it was, I wanted it. After a moment's hesitation, I slipped my own cock free of my trunks and we began to jerk off together, our cocks side-by-side.

"Your wife wanted me to cum, Paul. I was fucking her sweet mouth and she was massaging my balls and I wanted to sooo bad, but I knew if I did it was over. I pulled her to her feet and I told her I was going to fuck her. I'm ashamed to say there was nothing gentle about it. It wasn't a request. She couldn't have stopped me if she wanted to. She started to protest but I shoved my tongue into her throat and filled my hands with her titties and she just moaned instead."

"When I turned her around and bent her over the counter, the juices were literally running down her legs. Even soaking wet, her pussy was so fucking tight and she started coming again almost as soon as my cock slid into her pussy. I know it was wrong, but we were both just so damn hot, we couldn't stop ourselves."

"I guess that's about the time you walked in." He suddenly seemed to remember where he was and what he was doing. He stopped stroking and his voice took on a pleading tone. "I know it's no excuse, but we just got carried away. I never meant to do anything to hurt you or your family."

I was close to cumming and honestly didn't know what to say. 'Right' and 'wrong' were the last things on my mind. Looking down, he reached out and placed his hand over mine. "Let me make it up to you, Paul. We can make this right." Suddenly, I had a pretty good sense of what my wife must have felt.

I didn't say anything as he gently pushed me back on the bed and dropped to his knees. My cock had been close to the bursting point since the moment I saw him sliding into my wife. Whatever misgivings or anger or insecurities I might have had were simply washed away by desire. I groaned as he stepped forward and pressed the lengths of our two cocks together. Then, dropping to his knees he brought his mouth to my cock. I could feel his breath followed by the wetness of his tongue and kisses along my shaft.

Looking up and fondling my balls he said, "Let me do this for you, Paul. Let me do for you what your wonderful wife did for me." And with that, he let out one long vibrating moan and took my entire cock into his mouth. The sensation had my ass raising off the bed and my hands wrapping around his wet hair. On each upward stroke he would take me out of his mouth and lick and suck and kiss the head of my cock as he pumped me with his hands.

My cock was slick with saliva and pre cum as he repeatedly moved his mouth up and down my shaft. I could feel my orgasm building in my balls. "Cum in my mouth, Paul... fill my mouth the way I filled your wife's wet pussy."

With that, my cock erupted, spewing spurt after spurt of hot white cream into his mouth as he continued to pump up and down my shaft. I could feel my cum leaking out the sides of his mouth and down between my legs where he massaged it into my balls.

As intense as my orgasm was, what really amazed me was how long it seemed to last. Even after swallowing the last of my load, David slowly sucked my cock clean until the sensation got to be too much and I had to beg him to stop.
