We want to protect the ever-decreasing number of girls with small breasts! The long-awaited fourth installment of "Bin Cinderella" features Kotoba Kotoha Shizuku , the Cinderella of the small-breasted world. Her virgin, undeveloped body has been transformed into an erogenous zone all over. Her body has become so sensitive that it reacts just to a water pistol hitting her chest. When a huge penis that was big enough to get caught in the entrance entered her, her nipples became erect and she screamed. Minimum wholeheartedly supports girls with small breasts. (Small breasts are a talent) *There are no performers under the age of 18 in this work.
