Busty beauty Kurokawa Sumire joins the popular series devoted to developing the Spence breast glands, described here as the G-spot of the breasts. A specialist massages her naturally sensitive tits until they awaken, making her convulse, scream, and climax from breast stimulation. With her nipples deliberately denied during hard pounding, she loses control in repeated orgasms and squirting sex. Toys push the breast stimulation even further, causing heavy urination, before her painfully teased, rock-hard nipples are finally kneaded into an overwhelming, blackout-level orgasm.
