I've heard it suggested that faggots love 2 things ie. feet and cock. Seeing her lovely bare feet being humped by a big stiff cock is the perfect combination. We don't see the final outcome but I'm sure he cums very hard to the feel and sight of those gorgeous soft soles.
I like that she is a beautiful teenager and he is probably a fully grown man maybe in his 20s. His body is great and he has a big penis.. I think a footjob is so kinky. She is an angel!
