A young man named Hikaru confesses his feelings to the most beautiful girl in class, Hinano. Despite being married, he succumbs to her seductive advances, unable to resist her alluring body—with its transparent skin, G-cup breasts, and face that seems reserved just for him. As she teases him relentlessly about not giving her what she wants (presumably referring to creampies), Hinano takes matters into her own hands by grinding against him until they both reach climax. In the end, Hikaru can't help but apologize for losing control amidst their passionate encounter.
