Two shaved-pussy beauties, Yui Tenma and Ririka Yume, transcend their senior-junior relationship as gravure idols and plunge into lesbian pleasure. Excited by her junior's affectionate chatter, Yui grows aroused as the alcohol takes effect, then pounces on her, reducing her to a trembling mess with naughty words and erotic caresses. Responding to her junior's advances, Yui laps at her anus until she farts on the couch. Awakening to this new sensation, the younger girl recalls the cunnilingus she received and turns the tables, bringing her senior to orgasm. As soft skin and deep affection intertwine, the two are drawn into endless pleasure—licking each other's sensitive anuses, sharing ecstasy deep in their wombs with a double-headed dildo, and forging an inseparable bond as they become one.
