The university's bathroom transforms into a steamy playground as a student's anal cravings lead him to bend over the sink, his ass exposed and ready. The sound of water dripping echoes as he fingers his hole, his breath hitching in anticipation. The thrill of the forbidden sends shivers down his spine, and he imagines a thick cock replacing his fingers. As he hears footsteps approaching, he tenses, unsure if it's a fellow student or a professor about to catch him in the act. The door swings open, revealing a familiar face, and the student's heart races, wondering if this unexpected encounter will lead to a taboo lesson.
