New employee Hasegawa, who hates his boss, ends up staying at a hotel during a business trip. Unaware of the aphrodisiac in the alcohol he drank in his room... he is assaulted while sleeping and his overly sensitive body involuntarily orgasms and experiences sex with ejaculation inside. Despite it being the lowest act imaginable, the middle-aged boss's slimy techniques and perfect sexual compatibility cause a brain-frying orgasm. Repeatedly violated until late at night, drooling and sweating profusely while moaning in ecstasy. As the intense sex escalates, he is made to experience internal ejaculation multiple times, gradually becoming addicted to his boss's penis... The new employee seems to be overly affected by the aphrodisiac.
