Yes, one thing that I didn't mention was that the last thing that I saw of him and the girls was that he had one of those girls sitting on his lap in a dark corner a little out of the way, while the other girls sat close by and watched them, and he and that girl were getting really passionate with each other;
they were as close to each other as possible with arms around each other, and French-kissed and fondled.
The girl was feeling his arms and upper body, and he casually touched her breasts, her butt, her belly and between her legs, and the girl was actually making various half-suppressed moaning sounds at that point.
I am not sure how a situation like that would end, given that there were also those other 2 girls with them, but I am 100% sure that he had sex with that girl at the very least.
