This horny stepbrother can't resist the allure of his stepsister's panties. He sneaks into her room, drawer by drawer, sniffing each pair, his cock hardening at the intimate scent. He pulls out a lacy pair, his hands trembling as he brings them to his face. The aroma sends him over the edge, and he strokes himself furiously, cumming into the panties, his body convulsing with pleasure.
