Bride-to-be Sumire visits a bridal spa with her fiancé, only to discover that her therapist is a former classmate. Jealous that the woman he once idolized is about to marry, he slips her an aphrodisiac and turns the treatment into sexual conditioning, pounding her slender body until she squirts, convulses and pulls a glassy-eyed climax face. He even gives her a breeding creampie before her future husband gets the chance. Is Sumire really ready to walk down the aisle after being left spread wide and lost in pleasure?
