My boyfriend gave me the green light to fuck his best friend and his girlfriend [FFM]

For context, I’ve been fantasizing about my boyfriend’s (Ben) best friend (John) for some time. I’d picture him fucking me and even masturbate thinking of it. But I would have never thought of actually doing it, I accepted that even if we break up one day, I’d never do it out of respect for him.

Two months ago, we invited John and his girlfriend (Vicky) over to drink. Ben and John work together and spend all day long sitting next to each other in a truck. So we figured that if one of us would get the covid, all four of us would catch it the next day anyway. They’re the only friends that we see.

So we were all pretty drunk and some of us (mostly John and I) got pretty horny. We started playing with each other, I think that Vicky wasn’t that much into it but she wanted to please her boyfriend. Ben wasn’t into it at all, he was laughing and feeling quite awkward. He didn’t wanna be touched, so we stopped. But John kept teasing me and I was getting pretty wet… I honestly don’t remember how, but it got to a point where I was about to have a threesome with John and Vicky. I went to talk with Ben one on one, I asked him if he would mind. He said that he honestly didn’t care. I asked again a few times, like “Are you really sure?”, I couldn’t believe he was giving me a free pass. But he promised me that it was okay.
