[Ninomiya Ryouzou] Ultra C de Yacchao (COMIC Megastore H 2007-06) [CulturedCommissions]

An athletic girl in a form‑fitting leotard draws the lustful gaze of a neighbor, sparking a heated exchange that turns the gym into a stage for a reckless TKACHEV flip and relentless cumming. She screams that her pussy is stretching and that the man is pulling everything out of her, while he declares he’s fucking her in her leotard, driving the tension to a breaking point. The scene culminates in an intense, taboo climax that blends extreme pleasure with the raw edge of an unusual insertion.
