Watching another man with his hands all over my wife is one of the exciting lead ups to sharing her. Especially if they are on a dance floor and he doesn't realize I'm watching him feel her tits and squeeze her arse in public.
Happened by accident last weekend. I was not "letting" anything, she slept with a guy while she was on a business trip and she said he was pounding her so hard that his condom broke before he came.
I suspected, since she took condoms and lube with her. She didn't remember telling me. As I fucked her, I asked about her tryst. Also pissed to hear her say the condom broke when he shot his load, because he was pounding her so hard. .
