The neighbor conspiring with the wife to keep a chaste hubby horny is a stand-out. My other favorite is the husband whose wife passed the keys on to her lesbian lover. Obviously, I like the idea of the females teaming up against a locked guy.
This is one of the few times I have been successful in predicting which ones might attract your comment. The swimming girl seems so delighted to toy with the chastity victim, even though the situation pretty much just fell into her lap.
