Bored and horny, a sister confesses her arousal to her brother before their shower. She playfully asks him to help her "take the edge off," and he obliges, fingering her wet pussy and rubbing her clit until she's squirming. She teases him, saying she's already "raw," and begs for more. He obliges, pushing his thick cock into her, fucking her hard and fast until she's moaning and climaxing, her pussy clenching around him.
