The fourth installment of the highly popular series is finally here! This time, Ayano Kato, famous for her curvy, tight ass, takes the spotlight. Though close friends with the Hibiki-Hatano duo, Ayano is extremely shy when her anus is closely examined. Hibiki Otsuki's long, drilling tongue plunges deep into her anus, while Yui Hatano skillfully stretches her with expert finger work. As the stimulation builds, Ayano grows increasingly sensitive. Ultimately, she reaches climax in tears during a sandwich-style double penetration scene, penetrated in both front and back holes by dildos.
