I don't know why, but this is one of the most erotic images I have ever seen. It's the short boy's ripped, broad-shouldered body, and his toned pecs, and his large, very erect nipples. It's the rape-fantasy, I guess... a boy who normally wouldn't let anyone but the most perfect men touch him is being assaulted -- and unable to resist -- by a freak.
It's also a highly creative photo. And creativity arouses me.
