It's the semester break for Nathan Basic (Jake Adams) and after the ups and downs of his term at the Hentai Sex School, Nathan could USE a break. So, it's with excitement that Nathan arrives home at the apartment he shares with his stepsister, professional sex competitor Nadine (Carter Cruise). Anxious to tell her about his adventures at school, he greets her warmly, coming in for a hug. To Nathan's surprise, Nadine gruffly refuses his hug, insisting that she's sweaty from training. She rushes off, leaving Nathan surprised and disappointed. Later that night, Nathan, still wanting to spend time with Nadine, tries to get her to take a break. When she rebuffs him again, Nathan is even more disappointed. Nathan doesn't give up, and the next day, he arrives home with a bag of Nadine's favorite groceries, excited for the family bonding time that cooking a meal together will give them. Again, Nadine doesn't share his enthusiasm, swatting the bag out of his hand and insisting that he got the wrong groceries. As Nadine stalks off, Nathan shakes his head. What is going ON with her? Determined to find out, Nathan approaches Nadine the next day, interrupting her workout. Nadine begrudgingly listens as he tells her how confused he is about her attitude. She and Nathan used to be so close - more than siblings, they were best friends! But ever since he got accepted to Hentai Sex School, she's been acting weird. Nadine lashes out, angry that Nathan got into Hentai Sex School for no apparent reason while she's been working her ass off for years and they never accepted her. Nathan tries to apologize, but that only gets Nadine more fired up. What did they see in him when she's better at sex than he'll EVER be? Insisting that she'll PROVE her sexual superiority, she strips off her clothes and yanks Nathan's pants down, sliding his cock into her pussy in one motion. This faceoff seems to be what Nadine needs, but what will it take for her to realize that there’s no rivalry?
