Bisexual Monkey Thrust
This one takes three and some acrobatics. You've got penis-haver # 1 in the middle doing the most work. Vagina-haver wraps their legs around the penis-haver, being fucked / fucking. Both should contribute. Seemingly standard stand-up sex. Finally, you have penis-haver # 2 fucking penis-haver # 1 in the ass. Legs also wrapped penis-haver # 1. So if all 3 get their rhythm and thrusting right, it's magical. But requires the right people for sure.
Confused friend: Wait wait wait. So you're saying you were fucking your partner while also being fucked in the ass by some dude? And standing up, supporting both their weight just thrusting into each of them? What the fuck?
Penis-haver # 1: Bro, you haven't lived until you've experienced a bisexual monkey thrust. Trust me.
