Body Insurance: Sign on The Bed (1981)

In this outrageously erotic whirlwind, Mai ditches financial drudgery by diving into the sultry world of insurance seduction. Under the provocative tutelage of the debonair Fuyumi, she’s pushed to flaunt every inch of her tantalizing fertile body, using wild, over-the-top allure and sexual shenanigans to seal scandalous deals. Her steamy exploits escalate into an intense orgy of forbidden passion, targeting the irresistible female CEO with a dizzying blend of temptation and debauchery. As rival seductions clash and bizarre, masked deviant encounters add shock-value to the mix, every signature becomes a brazen vulgar climax—a wild, unapologetic celebration of lust, sex, defiance, and pure, over-exaggerated carnal ecstasy.
