To verify the rumor of "precocious anal sex," we contact a shy high school girl who is an anal virgin and calls herself "Seiko." We start with sensitive anal masturbation. We force her to masturbate in front of the camera, and she climaxes with her own hands. After that, we finally try real anal sex. After persistent anal caressing leaves her anus gaping, we have her first anal sex of her life. Then we have an enema that makes her agonize and feel shame. Next, she is given an enema while wearing her school swimsuit and bloomers, and she lets out a shameless fart from her anus, and finally she squirts a lot of raw juice and gets anal bukkake. And finally, we have two-hole sex!! This is the real anal life of today's high school girls!
