I actually watched this film starring Setsura Yuuhi, and it's truly a masterpiece for anal fetishists! The story follows Yuuhi as a stepdaughter who, three years after her mother's remarriage, gets manipulated by her stepfather over a school cheating incident. At first, she seems to endure bravely, but gradually becomes enthusiastic, making the plot irresistible. In her sailor uniform with twin tails swaying, her perky buttocks stand out, revealing a beautiful, light-pink anus. Long close-up shots showcase the anal ring with minimal pigmentation and neat wrinkles in an erotically beautiful way.

The stepfather character, played by Ozawa, delivers an intense anal licking scene that's awe-inspiring, with realistic depictions of tongue movements and the anus contracting. Each time she feels pleasure, the anus伸缩, boiling brain juices and sparking excitement. The transition from licking to anal insertion, culminating in a creampie scene where both vagina and anus tighten during climax, evokes hot sex reminiscent of times with an ex-wife. Post-sex details like semen and a pubic hair stuck on the anus are overly erotic, heating up the groin.

Despite Yuuhi's cute appearance, her masochistic acting shines, and the surprise moment when she utters 'gold〇' adds to the thrill. The wife role by Yoshii Miki hints at potential similar works, but this film focuses solely on anal themes. The pace is fast, with mild play like licking and vibrators, but the extended close-ups allow full enjoyment of the anus. As a punishment for a naughty girl, the butt play is a must-see for fans!
