Marilyn Sugar is living with her stepbrother, Stanley Johnson. Their arrangement is growing tense as Stanley grows sick of Marilyn sleeping all day. He wakes her up and instructs her to start taking more personal responsibility. In retribution, Marilyn gets out of bed and peels her nightclothes off right in front of Stanley. Stanley is really taken aback by his stepsister just flaunting her hot body like that, but now that Marilyn has committed, she isn't about to back down.
Putting on a bikini, she tells Stanley to rub sunscreen onto her shoulders. She likes the way his big hands feel on her body, so she turns around to have him rub down her collarbone. In return for her stepbro's help, Marilyn reaches out to feel that he's nice and hard. She coaxes him onto the bed and opens wide so she can suck his cock. Her greedy pussy is already nice and wet when she peels off her bikini bottom and then climbs on top of Stanley so she can rub herself all over him before adjusting her hips so he can slide on home into her tight twat.
Once he has his hot stepsis riding his cock, Stanley can't wait to get even more intimately acquainted with her. He lets her indulge in reverse cowgirl, then flips her on her back so he can eat her out and give her a firm pussy fingering. As Marilyn rubs her own titties, Stanley slides on home once again. He flips Marilyn onto her knees so he can fuck her in doggy, squeezing and spanking her ass until Marilyn cums hard. Then Marilyn returns the favor, blowing her big stepbrother's fuck stick until he rewards her with a mouthful of cum. Now that they've gotten intimately acquainted, they agree that it'll be much easier to live together.
