The next installment in the ultra-high-definition 4K-shot series "New: In Love Diaper Girls"! This entry features a lesbian couple—senior Yuuko (Sonoda Hinano) and junior Minami (Nana Maeno)—whose romantic relationship has only just reached the point of holding hands. Their love life remains stagnant, as they continue testing their feelings for each other through daily interactions. One night, Yuuko confesses to Minami, "I want to spend the night in your room." As hidden secrets between them slowly unravel, the two share their very first night together. This work is a pure love diaper yuri drama that carefully portrays girls struggling with incontinence and bladder issues as they experience their first intimate night. Captured with 4K cameras, the overwhelming visual quality delivers intense realism—the texture of diapers, the flow of urine overflowing beyond the capacity of children's disposable diapers, and close-up details of the girls' delicate bare skin, lips, and nipples during diaper lesbian acts—making this a must-watch title.
