Kenji, who finally landed a job at his dream company, decides to stay with his aunt and uncle in their Tokyo apartment while he searches for a place of his own. Though it's temporary, he's thrilled to be living under the same roof as his beloved aunt. With her husband away on a long business trip, they find themselves alone together. Kenji's feelings for his aunt grow stronger each day, and he eventually takes the bold step of using her lingerie as a sexual stimulant. Unable to resist the intoxicating scent wafting from her freshly removed panties, he wraps his cock around it... only to run into his aunt at the worst possible moment.
