After he's locked up I'd have him sit down and write a long letter to the fat slut with whom you caught him cheating. Tell him to describe in detail the nature of his relationship with his wife... that because of his cheap indiscretions he must now have his penis locked up in a cage and wear women's underwear... and that he's very willing and even happy to do this in order to make you happy.
He should explain that his wife is the one who decides in their family who has sex and who doesn't, not him, and that you are free to have sex with whomever you please while he is happy to grovel at your feet and do whatever he has to to earn your permission to orgasm, even if that means blowing your lover to get him nice and hard for you and cleaning you both up afterwards. And, he should also describe in detail how it feels to be locked up, in panties and a bra, sitting on the floor of your bedroom watching his wife fuck her lovers in their own bed.
I'll bet the fat slut would show the letter off all over town!
