Yui Tomita is a serious and shy girl who works at a local tofu shop, her heart fluttering with anticipation for a fated encounter. With the passing of a new anti-declining birthrate law, she finds herself suddenly falling deeply in love with her first partner. Having no prior experience with men, her body's delicate reactions—shyness and nervous tension—are vividly portrayed. As teasing foreplay and intimate moments build, excitement reaches its peak, leading to an intense scene of bareback creampie on her first time. This release features selected scenes from MDTM-466, scheduled for release on January 11, 2019, culminating in a special ending where their bond connects on a genetic level.
