The triple-crown winner Ren Hibiki makes her long-awaited return to the popular series that develops the "Spence Mammary Gland," a woman's new erogenous zone! The Spence Mammary Gland is the G-spot of the breast! Developed by a specialist in Spence Mammary Gland research, the sensitivity of the tail of the mammary gland rises rapidly! Her slender F-cup body arches like a shrimp in a state of demonic orgasm awakening! While experiencing repeated mammary gland acmes, her pussy G-spot is also gouged out by a big cock, sending her to heaven! The pleasure of toy torture to finish the mammary gland development causes uncontrollable shaking and spasms, leading to an incontinence orgasm! Even during a beautiful breast titjob, the Spence Mammary Gland is constantly stimulated, leading to self-climax! Finally, in sex where nipple torture is unlocked, her nipples, which have become more sensitive than her clitoris, are kneaded and crushed, resulting in a screaming squirting orgasm!
