He'll just look at their sex

«He will sit on the sidelines and watch how passionately and depraved his hot girlfriend has sex with his friend. He will not hide that it turns him on insanely and greedily, his penis is already strained in his pants from explicit scenes. His girlfriend's clothes have already fallen off, she's already sucking another's dick and it doesn't drive him crazy in any way, on the contrary, it excites him very much.»
