Scenario- you get home at 2am, your wife is in the loungeroom waiting, she's angry. She explains she knows you have been living out your footcuck fetishes at the local strip club. Your wife beings to play on that as she masturbates while you worship her soles, just the way you like it. She insults you, calling you a "footcuck" and "footbitch", and makes you thank her as you lick her soles. She then stops and gives you the ultimatum, she wants to be able to fuck whoever she wants whenever she wants, all while you worship her feet at the same time. The temptation is to great and of course you give in like the little cuck you are. Finally you cum as your licking her soles and worshipping her.
