Secretly film the wife? Haha! You'd need to work at a women's attire store!
She'd freak out if she actually knew someone was doing it. But the remote chance that she is being watched or filmed gets her excited.
And I would let you as long as it's a lot of cum. I like o make sure my hubby is well fed from my c*nt. I'm glad you're stroking your dick to me. Which story are you talking about? I've had a lot of stories here. Tell me which one and maybe I can tell you more about it and get you to squeeze a little more cum out of your dick.
