A curious college friend of the step-sister drops by, eager to meet her older brother. As they chat, she notices his growing bulge and, unable to resist, leans in to suck his throbbing cock. She expertly takes him deep, her big tits pressing against him as he groans in pleasure. She teases him, playing with his balls, before taking him back into her mouth, eager to taste his load. He cums hard, coating her tits in his warm seed.
