Itsukaichi Mei joins the popular series devoted to developing the Spence gland, billed as the breast's G-spot. A specialist massages and trains this new erogenous zone until she experiences her first breast-induced orgasm, twisting, screaming, and convulsing through repeated climaxes. Teased nipples and Spence-focused sex destroy her sensitivity threshold and trigger one squirting orgasm after another. Toys leave her drooling and trembling before she releases a huge amount of urine, and relentless nipple stimulation fully awakens her breast glands for one final overwhelming climax during sex.
