A curious young Chinese man, alone in his room, decides to explore the intense world of fisting using a glass bottle. He starts slowly, lubing up his tight hole and the bottle before cautiously pushing the head in. His breathing deepens as he works the bottle further inside, feeling every inch stretch his ass. He moans, pushing through the brief pain, and soon finds his prostate, sending waves of pleasure through him. He picks up the pace, fucking himself harder, until the bottle slips in fully, causing his ass to prolapse slightly. He gasps, a mix of shock and intense pleasure, before pulling the bottle out, leaving his hole gaping and red.
