A reclusive man becomes infatuated with Mirei, a cafe worker, and after a chance conversation through a job ad, attempts to approach her—only for his bizarre behavior to leave her confused and uneasy. Though she politely rejects him, the heartbroken man somehow makes her feel responsible, prompting her to offer counseling. However, his "consultation" quickly turns into near-sexual harassment, and though visibly shaken, Mirei ends up servicing the shut-in. As she gently gives him a handjob, he suddenly feels a spark when his hands touch the goddess-like Mirei's breasts. The man then lunges uncontrollably, burying his face between her legs and relentlessly going down on her until she climaxes. While receiving fingering, Mirei squirts a massive jet of fluid directly onto the recluse's face. Turned on, she starts masturbating him and shyly asks, "Can I lick your cock?" before giving an eager blowjob. Pushed past his limit, the man attempts penetration but fails to put on a condom properly, thrusting his bare cock deep inside. Initially protesting, "No, no, bareback is bad!", she soon erupts in pleasure with each powerful thrust, climaxing repeatedly. Lost in ecstasy, he pounds her relentlessly with nonstop piston strokes, filling her with a creampie. Confirming the creampie, he immediately thrusts in again without pause. Ruthlessly bringing her to orgasm after orgasm, he machine-guns her with his hips. Without mercy, he cums inside her a second time, and before she can recover, he plunges his cock in once more. Even as Mirei, nearly passing out with rolled-back eyes, pleads, "I can't anymore! I have no strength!", he creampie-fucks her yet again. He flips her onto her back, mounts her in missionary, and delivers a crushing final creampie. She collapses, spent and unresponsive, but the sex-crazed monster keeps slamming into her—ultimately unleashing a fourth creampie in his insatiable climax spree.
