Riko, who has a problem of not only breasts but also general frigidity, visits the "Boob Research Institute". She is made to drink "pleasure inducer" there, and while she is massaging her big tits, she gradually becomes sensitive. In addition, she is whole body low frequency, electric massager, rotor torture. She was restrained and she was painted with a special lotion all over her body, received pleasure treatments such as intense milk rubbing & intense Irama torture, and completely sexually developed. In a 3P with her directors, she shakes her big tits and goes crazy and cums!
