REBO-028 - Insane hips.. The brutal training of Yuumi's underdeveloped, curvy ass

Yuumi has massive breasts that are obvious even through her clothes. She hates the attention, but to us, she's a total treasure. We get her into a swimsuit to check out her body, and it turns out her ass is just as insane as her chest. We convince her she could be a star, and she's so desperate to make it big that she gives in and lets us have our way with her.
