My b/f walked in on me getting my ass reamed by our newspaper kid, who is an early teen but is hung nicely. B/f was initially pissed but then made a deal to fuck one of his co-workers whom he knows is hot for him, in front of me. I said, "hell, why not?"

What happened while I was watching them surprised me and it was a giant turn on so I undressed and gradually joined in. As it turns out, she's far better as a sex partner than he is so now I see her on the side. We go at it like mad. She was my first bi lady and I'm sticking with it.
