Personal trainer Mizuki uploads workout videos to gain views from followers seeking erotic buttocks, and diligently solicits students who want in-person training. However, Mizuki has a bad habit. When she realizes a student's erection, due to her large buttocks, is the shape, firmness, and size she likes through their clothing, she neglects training and focuses on penile development! Even after ejaculation, the erotically writhing large buttocks won't let go! Intense pleasure is guaranteed with Mizuki's Spartan large buttocks training!




















Wow... the sheer size is overwhelming. She used to be the 3rd most 'pure' idol, and now she's the 2nd biggest-assed woman?! Go wild with the incredibly seductive mature lady, Misuki! Definitely a keeper, for real.
The ass was amazing, but the boobs were no joke either! A masterpiece, I admit. I want to watch it again...
Mizuki-chan's butt and training wear combo is just *chef's kiss*! The innuendo is so subtly done, it's impressive. I'd love to get a workout from a big-bootied older sister like this... Definitely a keeper!
Honestly, it feels limited. It's cheap and feels hastily made. You can tell she hasn't been working out her glutes. That raw ejaculation scene in the middle was just unnecessary. Lacks depth...
