Tim Monster Cock's step-sister, Siri, knows what she wants, and it's not her boyfriend's dick. She wants Tim's big cock, and she's not afraid to take it. She sneaks into his room, finding him asleep, his massive cock tenting the sheets. She strips, her body bare and ready, and wakes him with a blowjob. Tim, aroused, flips her onto her back, fucking her hard. Siri's tight pussy struggles to take his thickness, but she loves every inch. Tim pounds her, their bodies slapping, until he cums inside her, filling her with his load. Siri, satisfied, cleans his cock, swallowing the remaining cum, ready to face her boyfriend, knowing she's been well-fucked.
