You have to know when Ray is in the locker room, some lads who thought of themselves as straight might start to do some soul searching. They can't stop looking at that, and then they get a funny feeling in their tummy.
And then when they're in bed that night and trying to wank off to a fantasy about some big-titted skank, they can't stop thinking about what they saw hanging between Ray's legs. And then they realize it's not the skank who is getting them hard -- it's what they saw in the locker room.
