Legendary busty star Otsuki Hibiki joins the popular series devoted to developing a new erogenous zone known as Spence's tail—the so-called G-spot of the breast. A specialist massages and conditions the area until she experiences shocking breast orgasms, screaming, squirting, and convulsing. Nipple teasing and sex make her shake and spray around the cock, while toy stimulation leaves her weak-kneed and urinating heavily. After prolonged teasing, hard piston strokes and nipple play end in a creampie orgasm so powerful she nearly blacks out, revealing even more erotic potential in her famous breasts.
