An interesting threescore sexually btwn MMF, FFM, MMF+, etc. at the same time. I.E: she's giving him head as she's being pleased by s/he either oral or penetrating. Think A-frame, only lying down. And switching positions is some hot-ass fun for dessert in the best-ever orgasms....A nice cream sanmich!
Sam: I had me some good A-frame with my boo and her girlfriend from the club last night as a late night snack.
Ty: Yeah, well, my dessert was better'n a hot nice cream sandwich.
