Two siblings, bound by taboo, find solace in each other's arms. The brother, unknowingly tempting, sports a throbbing erection, while his sister, a captive of her desires, can't help but lust after the familial forbidden fruit. She offers a hesitant handjob, her small hand struggling to contain his massive cock. As she pumps him, his pre-cum lubes her grip, driving them both to the edge. Finally, he explodes, coating her hands and stomach with his hot, sticky cum. They freeze, a moment of shared guilt and ecstasy.
