Serene-sama decides to take personal boxing lessons. Her cute smile and large breasts visible through her cheongsam immediately catch the trainer's attention. She enthusiastically engages in training, throwing sharp, powerful punches that gradually excite the trainer. Noticing the bulge in his groin, Serene-sama's demeanor suddenly shifts—the pleasant atmosphere vanishes as her sense of justice awakens and she becomes filled with righteous anger toward perverts. She overwhelms the trainer with face punches, body blows, and direct groin strikes, then proceeds to punish him further with electric massagers, groin kicks, and mounted punches. The session culminates in a relentless barrage of facial punches that send him into blissful oblivion. Recommended for those who enjoy being disciplined and pummeled by a charming, attractive woman.
