Dated a girl, Laura (24F) for about 3 years. We were very in love, but we were also young, and near the end pretty much hated each other (arguing, both cheating). It’s been some years now but we have made a pretty miraculous turnaround. We see each other at bars and gatherings (still have a lot of mutual friends) and always have fun teasing each other and hanging out. We know we aren’t compatible so we keep it platonic (there are definitely some inappropriate comments and teasing and flirting that goes on, but come on, that’s just fun).

Anyway, last night there was a massive party and she had brought her sister, Veronica (19F). While Laura was tall and petite, Veronica was a bit shorter than us, and a bit of a Sydney Sweeney type.

As the night goes on, Laura leaves to drive someone home, and immediately Veronica starts flirting with me. One thing led to another and between the flirting and the booze, we sneak upstairs to one of the bedrooms and start hooking up. It was a fucking thrill. The fact that she was my ex’s younger sister, we were drunk, and I’d always dated petite girls, so having sex with someone who has huge tits and a round ass had me cumming real quick.

I was fucking her from behind, holding her up from her elbows I could see everything jiggle in the mirror. She told me she wanted me to finish inside her, and as I was finishing, her sister burst through the door screaming. Veronica started screaming back, Laura was hitting me, so I just grabbed my clothes and ran. Apparently someone at the party called her to tell her they saw us sneaking upstairs together.

Fuck.

So now I’m hiding out not really sure what to do. Veronica says she wasn’t on birth control. Laura wants to kill me. Veronica wants to keep sleeping with me. I know I’m an asshole. But I kind of want to keep sleeping with her too?
