Lexi Luna is trying to get ready for a function and she needs her stepson, Jay's, help getting her necklace on. Jay is put off by the way Lexi waltzes into his room half-naked wearing a demi bra, panties, and a short robe, but he does as she asks. Late, Lexi walks in on Jay in the bathroom while he's masturbating. Jay is embarrassed, but Lexi acts like it's nothing. The next day, Jay is still in bed when Lexi goes into make sure he's up for school. He already had morning wood, but seeing his mommy in another bra and panty combo gets him stroking it.Pulling the covers off, Lexi comments that Jay can't go to school like that. He keeps on stroking it since Lexi is encouraging it. She helps out by popping her titties out of her bra so he has some visual stimuli. When that's not enough, she leans in to deliver a big titty fuck. Still more desperate measures call for mama to start sucking Jay's hardon with a deep throat BJ that she hopes will do the trick. Jay still can't cum, so Lexi resorts to truly desperate measures.Peeling off her panties, Lexi hops onto Jay's dick and starts riding him as her big boobies bounce around. When she turns around for a reverse cowgirl ride, Jay gets an eyeful and a handful of that big ass! He gets to enjoy Lexi's big booty even more when she lets him pound her doggy style. Jay is close to his finish line, and he crosses it as Lexi turns over so he can stick it back in. Her big jugs are the perfect place for Jay to pop his load as he finally gives in to mommy's orders and cums.
