"I mistook my sleeping mother-in-law's ass for my wife's ass and immediately inserted it without knowing it was my mother-in-law. " The first omnibus of the series! I felt good when she squeezed me tighter than usual... Eh, my mother-in-law!? 480 minutes of accidental sex with someone I thought was my wife. I'm going to fuck her in a wide-open anal position! I'm going to hold her bouncy, plump ass and piston her from behind to fill her with plenty of seeds! Even though I know it's my mother-in-law, I can't stop now!
