From beginning to end! A seductive, large-assed personal trainer, Yayoi Mizuki, reveals her sexual desires to prey on her students (DVEH-037).

Personal trainer Mizuki uploaded training videos to attract fans interested in sexy buttocks and diligently taught students who wanted in-person training. However, Mizuki has a bad habit. When students get erections because of her large buttocks, she can feel the shape, hardness, and size she likes through her clothes, so she abandons the training and focuses on penile training instead! No matter how many times she ejaculates, Mizuki's emergency large buttock training is always breathtaking!
