Just watching? I think you underestimate moi.
My 2 Mistresses did that to me long ago.
Why, why, why do most associate fucking a man's ass as gay or him being feminine? That's a giant load of crap. Dress him up like a woman WTF never! Love masculine men and love giving them the strongest, longest screaming orgasms ever and yes that does involve the prostate.
