Hidden from prying eyes in the dark confines of their closet, these siblings surrender to their taboo desires. The brother, his cock throbbing with need, guides his sister's small hand to his shaft. She strokes him tentatively, her inexperience evident, but her eagerness clear. He teaches her, his voice a low growl, showing her how to grip him, how to move her hand. She learns quickly, her breath coming in short gasps as she watches his cock grow harder, longer. He can't hold back much longer, his body tensing as he spills his load into her waiting hand, their sinful secret safe in the darkness.
