My first [M/F/M] group experience | 2016

It was a generally uneventful night, not unlike most others, when out of the blue I received an IM from a couple on a particular adult dating/hookup website I frequent. Mind you, I'm usually wary of such things. I'll typically say I might be interested but am very straight and won't "play" with the male. This is typically a deal breaker as most bi males in couples want a male that both partners can play with. I cautiously accepted the IM and explained my strict heterosexuality and, to my surprise, he was fine with it. He explained his desire to help fulfill his girlfriend's fantasy of him finding a stranger to come surprise her in the shower and then tag team her in bed. After a quick back-and-forth of due diligence verifying neither of us were impostors, it was off to the races.

Needless to say, I was a little nervous when he let me in and led me into the shower where she was bathing. She was certainly surprised when he pulled back the curtain, but was immediately pleased that her request was being fulfilled. He needed to take a phone call and left us to get acquainted. She and I showered together and made small talk. Instead of jumping straight into it, I took the opportunity to make sure I was as fresh and clean as possible before getting started.

We moved things to the bedroom and things escalated quickly. In no time, I was going down on her while he was making out with her. Then she sucked on my cock while he went down on her, before switching it up with her sitting on my face and stroking me while sucking on him. Next, she was on her back getting pounded by him while I fucked her mouth. After a while he invited me to fuck her, and I obliged. She offered herself up to me, doggy style, back arched, pert little bubble butt sticking out and begging for cock. I grabbed her hips and slid in to her, growing harder listening to her moans. She quickly got loud, insisting that I fuck her as hard as possible. Eager to please, I granted her request and pounded away as she yelled epithets of encouragement and enjoyment.

We switched things up yet again, and she sucked my cock while he ate her out. Next, she was riding me and yelling again, but we soon had her on her back again and I fucked her as hard as I could. You might even say I fucked her violently. She screamed out in pleasure as I achieved a rather intense orgasm. In no time, I was kneeling next to her head getting sucked and stroked as he ate her out from the edge of the bed. That's when the slapping and choking started.

He had told me she liked it, but said he'd take the lead on ratcheting it up. I was taken a little bit by surprise with the suddenness and force with which he slapped her face. I might have even been worried had she not gasped with such pleasure, and it wasn't long before I was poking my dick into the inside of her cheek and slapping her as well. I'd never choked a girl before, and it was with no small amount of trepidation that I eased my hand around her throat before being encouraged to grasp more aggressively. Just as she was about to squirt into his throat and all over the bed, she asked me to fuck her throat and get as hard as possible in order to fuck her asshole.

And just like that, that perky little butt was aimed at me again, this time with a tight little butt hole politely requesting the presence of my cock while she sucked him off. After generously lubing up to make sure I didn't cause any discomfort, I shoved my throbbing erection into her eager asshole. The epithets were louder and more encouraging than ever, and I grabbed her hips and fucked her ass enthusiastically before cumming extremely hard.

While we caught our breath, a cellphone timer went off. The ball was over; she had work in the morning and needed to get at least a little sleep. I thanked them again for the lovely evening and they thanked me for coming over on such short notice. I got dressed, went home, took a shower, and fell asleep. It was a pretty incredible experience. Today, I was informed that she enjoyed it very much and will likely invite me for some one on one time in the near future. Talk about happy holidays!

P.S. Reddiquette question: If a comment asks which site it was, is it acceptable to answer? I deliberately left that out of the post in case such things are frowned upon.
