In a steamy twist of fate, a brother's private moment is interrupted by his sister, who finds him jerking off to porn. Instead of being embarrassed, she offers to help, kneeling before him and wrapping her small hand around his throbbing cock. She strokes him expertly, her grip tight and steady, bringing him closer to the edge. His breath hitches as she leans in, her tongue flicking out to taste his pre-cum. She moans, the sound vibrating through him, pushing him over the edge. He explodes, his hot cum spurting onto her eager hands, coating them in his sticky seed.
