Camping Trip With My Mom And Girlfriend

This summer my Mom and her boyfriend, as well as me and my girlfriend, all rented a cabin for a weekend getaway. It was intended as a normal and innocent fun family activity, which it was for the most part. Except that there was lots of drinking involved, and on our first night there, we all ended up having sex together in the same room. All of us meaning me with my girlfriend, and my mom with her boyfriend. This ended up happening twice over the course of the entire stay.
There was no "crossover" so to speak, meaning we both stuck to our respective partners. That's not to say we were reserved at all; we all got pretty down and dirty right next to each other, even on the same bed the second time around.

Though there was no inappropriate touching between me and my mom, nor my girlfriend and Mom's bf, I hate to admit that there's a part of me that wished there was. I kept imagining how hot it would be to see my Mom and gf play with eachother. I was even a little turned on by the idea of my girl fooling around with my Mom'a bf. The worst part is I even had an urge to feel up my Mom. I wanted to grab her boobs or better yet, suck on them (they happen to be extremely nice) but unfortunately did not have the balls to go for it. Not in front of her bf and my gf at least.

Maybe if it ever happens again, though it probably won't, I'll take it a step further.
