Yuno, the No. 1 girl at a sex shop, was in trouble. She seems to be in love with a customer named Uchida, who has a strong libido. He doesn't seem to be in love with her, but is excited by her face and appearance as she orgasms. Uchida is not satisfied with just her orgasmic face, and the more she convulses and distorts her beautiful face, the more he is excited by the contrast. He is the ultimate pervert. Uchida has a request for her again today... I wonder how many times he has to make her orgasm before she is satisfied... But before long, Yuno's body is unable to forget Uchida's techniques... "I've changed my clothes. Does it suit me?... Are you going to make me orgasm again today?" "Of course. Yuno's ahegao face is the best." "But please be gentle. If you orgasm too much, your work after this will be in trouble..." "It's okay. Leave it to me. As long as you feel good, that's all that matters." As a result of leaving it to him... he will be made to orgasm to the point of going crazy. Yuno's naughty instincts are awakened as she is tortured using the full range of toys available. She climaxes many times with nipple teasing, blowjobs, titjobs, collaring, restraints and blindfolding. Kokoro and body are corrupted by choking sex and spanking training play, and a large amount of sperm is ejaculated inside her. It seems that Yuno's body has become one that cannot forget Uchida...
