Mommy stops by her son’s house, where it seems him and her daughter-in-law have been trying to get pregnant but have had no luck.. She says she can help them out if they really want to have a baby. You see, Mommy is actually a Futa and has a great big cock that is extra fertile and ready to impregnate when she's in heat!
Mommy whips it out and shows it to both of them, while talking about how easy it is for Futa to breed. Mommy sees they are both getting turned on and tells her son to take out his cock first. She sees how tiny his penis is, realizing it's no wonder he can’t get his wife pregnant!
She doesn’t give her son a choice and makes him suck her enormous cock to get it nice and lubed up.
