I’ve been to a sex party and a separate “gang bang” in London.
The sex party was door fee, probably 30-40 people in a mansion 2.5:1 male:female (most female were professionals). Condoms required for all activities but I did get to do some DATY. Some great views, but don’t go if you’re worried the biggest dick you’ve ever seen will scar you for life.
The GB was supposed to be 2 girls, but one dropped, and only 4 guys or so were there. It was in the basement of a different mansion, felt a bit scary to getstarted but it was fine. Bare is much more available there and I creampied her twice, once while another guy was in her ass then mouth.
I’ve also done a 2 girl threesome at an Asian apartment that was quite nice. Haven’t had the best luck otherwise with 3somes.
I think if we could get a crew to host a party with 2-4 girls and roughly those ratios (like $140 hot a couple hour party) it could work nicely.
I’m in San Jose but maybe with the right level of planning I could make it to socal or would be interested in a threesome partner/party up here.
