I've had a MMF threesome with my fuck buddy and a girl. She watched us suck each others dicks for a bit, then my fuck buddy fucked me. After that, she joined in and we both fucked her.
I've had a MMFF, just fucked the girls.
I went to a male orgy, got my dick sucked by a couple of guys, fucked a guy, sucked a couple of cocks, got fucked by a couple of guys, and got spit roasted.
