Kinky Couple - Balls - Imagine how he feels?

A girl flirts with a guy who is wearing the smallest possible chastity belt. A guy with no dick and only balls. And the girl flirts with him, licking his balls. He cannot get excited and realize his sexual energy. He can only enjoy the way she sucks and licks his balls. Unusual fetish. The guy feels completely helpless and just looks. And the girl continues to play with his balls.
