Katarina goes into Miles' room to borrow something and catches him masturbating. Shes grossed out and covers her eyes, telling him to cut it out, but he doesn't. You could help me out he suggests, but this notion seems repulsive to her, since he's her brother. But his buddies told him about the other night at a party when she sucked 4 dicks in a dark room at a party. He knows she likes it and if she looks at the wall and just focuses on the dick itself she doesn't have to think about it being attached to her brother. He pleads with her, and she agrees to give him a blow job and that's it. So she starts to suck his already hard cock, drooling all over him and loving it. She moans as she shoves his dick all the way to the back of her throat. He vigorously rocks his hips, pounding her face hard until he cums and she swallows his load.
