First ... wow to all the PMs I got! Thanks everyone (who was nice) :)
Here's pretty much what happened...
Two of the three guys showed up, so with my FWB, that left 3 guys. At first, I fixed them some drinks and innocent flirting. I got grabbed a small amount and liked it. Then we watched a video of me, it was just one thing (I thought there would be more). It was late night anal sex where I farted bad at the end, he thought it was funny and still humiliating. I didn't care either way.
