Jay Romero's stepsister, Madi Collins, is so extra that it's really holding her back. Jay tries to indulge her, but eventually his patience wears thin. He offers to help Madi stop being extra. Madi accepts, so Jay instructs her to put on a bathing suit and meet him in the shower. Madi's first challenge is when she walks into the bathroom and sees that her stepbrother is naked. Jay patiently explains to her that no one wears a swimsuit in the shower unless they're extra, so Madi agrees to take hers off. She joins Jay in the shower, where he says he's going to start with warm water and then slowly make it colder.

Madi wants out ASAP once the water starts cooling off, but Jay tells her she needs to wait until her nipples are extra hard. Madi insists he feel them to see if they're hard enough. With Jay's hands on her tits to make sure she doesn't have to endure any more discomfort than necessary, Madi learns how to master cold water. Next, Jay tells his stepsis that she's going to have learn how to take big cock. That's the only way Madi will learn how to tackle hard things. Madi is nervous, but Jay insists she needs to learn. Eventually Madi agrees, but she can't like it because she's Jay's stepsister. Leaning forward against the shower wall, Madi takes every inch of Jay's big one while agreeing that maybe it is, in fact, okay to like hard things. She also realizes she doesn't care if Jay is her stepbrother; she just wants him to fuck her.

They get out of the shower and into bed where Madi climbs on top of Jay and tries him on for size in reverse cowgirl, which gets her feeling nice and hot for more. Climbing off to lick her own juices off Jay's fuck stick, Madi turns around on her hands and knees so that Jay can fuck her from behind. Getting it in doggy makes the horny redhead moan long and loud, which just makes Jay double down on how hard he gets her to take it. He rolls Madi onto her back next and pins her knees up at by her shoulders to open her up nicely. Watching that pussy gobble his dick and knowing his stepsis has even squirted for him is the ultimate aphrodisiac for Jay as he eventually spoons behind Madi to give her one more big O. When Madi has sucked Jay to the brink of cumming and then opened her mouth to take his cum shot like a good girl, Jay pronounces her well on her way to fixing her extraness.
