double adapter 

A gay man in the middle of a gay threesome .
He takes it and gives it at the same time.
Timing is everything along with good rhythm.

Rod is just a giver and bob is a real taker but Ben swings both ways so he plays double adapter in the threesome.

When a man inserts his penis into a woman's vagina and another man inserts his penis into her anus.

Up for some double adaptor?
