After a month-long period of abstinence, Riku and Kanna Misaki lose their inhibitions and give in to overwhelming sexual desire. They passionately tease and dominate each other's bodies, endlessly serving one another until utterly satisfied. The prolonged abstinence has driven them to the edge—no matter how many times they climax, it's never enough. Riku's large penis drives Kanna into deeper pleasure than ever before, as the two chase ultimate ecstasy toward the end of their after-school encounter.
