The legendary erotic actress Kurea Hasumi finally makes her long-awaited appearance in the popular series dedicated to developing the "Spence Mammary Gland," a woman's new erogenous zone! The Spence Mammary Gland is essentially the G-spot of the breast. Under the development of a specialist in Spence Mammary Gland research, the sensitivity of the tail of the mammary gland skyrockets! Her usual teasing expression gradually twists with pleasure, and her slender yet voluptuous, beautiful huge breasts bounce wildly as she reaches an intense climax! She ascends to heaven during intense piston fucking as a big cock gouges her G-spot while she experiences consecutive mammary gland acmes! The final blow of toy torture brings a shaking, hip-collapsing, incontinent orgasm! Even during a titjob, her Spence Mammary Gland is constantly stimulated, leading to a self-climax! In the nipple-play unlocked sex, her nipples—which have become 100 times more sensitive from constant teasing—are kneaded and crushed, leading to a screaming, ascending orgasm!
