Uh, mom, now i am obsessed with your asshole. When can we get that out of my system? Or into your system? Yeah, I definitly need to fuck you in the butt, or i won't sleep tonight.
She shouldn't have said "get it out of your system" a dozen times, but me, offering me those big giant jugs and jacking me off, I'd blackmail to do it whenever I wanted or I'd rat her out, lol
