Your lesbian bestie KNOWS that you're gay. It's clear. Everybody knows it. She just wants you to admit it. She even pulls her own tits and pussy out to prove it - look! Your cock is barely hard at all, she says. But once she shows that ass hole, and it starts to wink at you - that's when your cock really twitches. You can stroke to her ass, and if you cum - that'll be all the proof she needs that you're gay.
