I'm so excited...can I remain an anal virgin any longer? Sayuri, a petite, healthy, and cute-looking girl, was curious about sex and asked me to film her first anal sex. As she wished, we started with anal finger insertion, then toy expansion, then her first anal ejaculation, and finally she experienced the pleasure of double penetration... This work is a documentary of a loli anal first infidelity and anal ejaculation, depicting the tension, anxiety, and anticipation of a girl having her first anal sex.
