Do not waste your time. There is no bi and no party. The guys do nothing with the females except suck on their strap-ons. The 2 females do a couple of the guys with the strap-ons, but none of the sex is exciting. The girls never spread their leags so you never see their pussy or assholes. It took almost 50 mins before any sex started. Instead of jerkin to the movie, I was busy visualizing mental images of other past movies just to get off.
