I’ve known this dude for years, and there’s been a lot of mutual sexual tension between us. We hooked up once but have never had sex because one of us would be seeing someone when the other is single. He messaged me last week saying his girlfriend was planning a surprise for his birthday, and they were wondering if I would like to “join them”. I’m bi and have never had the chance to have sex with another girl, so I eagerly agreed.
I told my friend-with-benefits pal (who is also the Dom to my sub) about the threesome and he told me to come to his house beforehand so he could give me a dildo to have inside me while I drove to/from the hotel where I was meeting the couple. I got to my friend’s house and he wanted to fuck quickly before I left but another friend was there, so we snuck into the bathroom. He immediately pulled down my pants and started fingering me, and after I came he bent me over the sink and fucked me from behind. He pulled out and told me to suck his cock clean, so I did. When I stood up, he fingered me some more, even bending over to lick my clit, and then put the dildo inside me. Unfortunately the dildo hurt too much when I sat in the car, so I messaged him saying that I was taking it out, and he replied that I would have to be punished for that later. I told him I understood, and then headed off.
