Ryuuta, a popular young hairstylist who often gets hit on by older female clients, works closely with various women's hairstyles and makeup, gradually nurturing a desire to become beautiful himself. This time, he chooses the name RENA and prepares to transform with an idol-like outfit. Ryuuta carefully examines her body, testing the sensitivity of her nipples and anus. As the process unfolds, she increasingly becomes more feminine. In a strange turn of events, she ends up receiving a penis while simultaneously squirting cum like a tube of toothpaste.
