I'[M] fucking my neighbors girlfriend….with him

So to cut to the sweet stuff. I’ve seen my parents a lot less because they’ve been busy from work, so I’ve been spending more time with my neighbours which I rarely do. Honestly they’re great people. They were telling me about how they afforded the house next door, their jobs and we end up playing games a lot at night.

So a couple times the girlfriend (Let’s call her Alice) called me cute. I noticed her staring at me too, with hunger. Her eyes were almost drooling sometimes. It gave me a hunch but I never thought too much of it

Maybe early December he was drunk (I don’t drink, they do) he was falling all over the place so we dropped him into bed. After me and Alice went downstairs we talked a fair bit, got close and I looked at her and kissed her. She very enthusiasticly pulled me closer. I realised I fucked up and pulled back. I apologized, but then she slowly explained to me that they’d been in “that lifestyle” for a while.

I was confused, so she calmed me down and she talked about how they were “swingers” showed me pictures which made it a bit more believable.
