My Wife busted me trying to take a sneaky candid this morning. I thought she was asleep, but those pretty blue eyes popped open and I got, "Here, let me make this easier for you."
Your wife is pretty much just a sex object for your bully. Nothing but a toy for him. So why would he share his sex object with you? Isn't it only reasonable you never get to see her naked again? He owns her tits, not you.
