"I will never have anal sex in my life! Even virtual sex would bother me!" says Saki Ninomiya, who completely refuses anal sex. For her fans who are dying to have sex, she tried virtual anal sex just once. This is the first time that her anus has been so closely observed, touched, and humiliated! The sound realism has also been improved dramatically in this work, so imagine Saki's anal sex and masturbate!
