When you're having sex while playing games with your
boyfriend/girlfriend.
Does not matter who or what you're fighting - if your other half wants to have sex and play games, you're having
game sex.
During the act, you're free to
change styles but you must keep having sex until you're done playing.
Me:
Dude, what the hell happened? You just disappeared from Skype last night!
Friend: Me and my wife had
game sex while fighting the final
boss.
Me: ...What in the actual fuck?
