Gianna Dior needs her stepbrother Lucas Frost's help to practice for her beauty school exam. She asks if she can cut Lucas's hair, and he initially says no. After some negotiation, Lucas agrees to do it for a blowjob. When that doesn't work, he tells Gianna that he'll just be looking down her shirt the whole time but that he'll do it anyway. Relocating to the kitchen, Lucas lets Gianna put the cape over him before noticing a hole at a very convenient spot. He asks Gianna if she's been jerking off other guys as she gives them haircuts and she denies it.
As he told her he would, Lucas pervs on Gianna's bra as she leans in to cut his hair. When he's nice and hard, he pops his dick through the hole in the cape. Gianna freaks out, but Lucas convinces her to touch it by claiming that the only way it'll go away is if he gets a handie. Gianna reluctantly agrees and then stays quiet as Lucas undoes her shirt so he can palm her big breasts. He takes the opportunity to coax his hot stepsis into sucking him off.
Now that Gianna has gone as far as a blowjob, it's no problem for Lucas to talk her into sex. She starts by pulling her panties aside and riding his fuck stick as he sits in the chair. They both shed their clothes, then Gianna climbs into a different chair and spreads her thighs so Lucas can dominate her nicely trimmed snatch. Leaning over the table, Gianna lets Lucas fuck her from behind until he pulls out and covers her back in jizz. Satisfied, Lucas peaces out on his sis instead of helping her prep for her exam.
