With the issue of the declining birthrates becoming more severe, men with exceptional sexual prowess are valued and sought after in this modern Japan. In a school filled with beautiful women, you and your ugly mug spend your days living as an unpopular and shunned outcast. One day, rich heiress Kotone, one of the most beautiful and popular girls in school, catches you popping a boner. Having thought yourself bellow-average in every aspect your whole life, you're shocked to learn your member is actually world-class, top-tier schlong! At her invitation, you and Kotone have sex for the first time, and the result is the large-breasted, angelic princess going crazy for your dick, reduced to an onahole who devotes her everything to you! Having now realized the unrivaled greatness of your own cock, one after the other you seek to claim the top beauties of the school as your eager sex toys. From the disciplinary committee president to the swimming club's ace to the cute gyaru, their huge tits and lewd holes are yours to fuck any way you want in the high-school life of your dreams!
