You and your wife are visiting your mother in law for the weekend. You and your mil have never gotten along and she's always mean to you. She drags you into her room in the middle of the night while your wife is in bed so she can tell you that you are no good for her daughter. She insults you over and over again but all you can do is stare at her cleavage in her nightgown. She notices you aren't listening to word she says and sees where your eyes have rested, and notices the bulge in your pants. She aggressively grabs your hard cock through your pants and insults you more. You're such a no good loser for lusting after your wife's mom! She starts to jerk you off all the while insulting you but that only makes you more hard. When she can see you're about to cum she pulls away. You don't deserve to cum. You probably sit at home jerking off thinking about your cock between your mother in law's tits don't you? She starts to titty fuck you and you of course don't complain. You're such a p.o.s for cheating on your wife while she's down the hall in bed. But all you can do is enjoy watching your mother in law bounce her huge tits up and down on your cock while insulting you, and you explode all over her massive boobs, proving your mother in law's point that you are no good for her daughter!
