To experience the current phenomenon of "early anal intercourse," we meet a shy and pure schoolgirl named Seiko, an anal virgin. It begins with her naturally sensitive anal masturbation, and when forcefully stimulated in front of the camera, she reaches orgasm using her own hands. Intrigued by her sensitivity, we proceed to genuine anal sex. Her anus is gradually stretched through persistent foreplay, leading to her first-ever intercourse through the back door. Overwhelmed by the pleasure, she writhes in ecstasy, then undergoes the embarrassing experience of an enema. Dressed in her school swimsuit and bloomers, she is given an enema into her anus, and the sight of her shamefully releasing indecent farts from her rectum is astonishing. Finally, she releases a flood of natural juices, receives a creampie on her anus, and moves on to double penetration. The real anal truth of today's schoolgirls revealed here!
