This breast-focused experiment uses Miyu Kohinata's exceptionally soft, full H-cup tits to prove that nipples are not the only source of pleasure. Every detail is explored: the Montgomery glands around her areolas, the breast tissue extending toward her armpits, the edges of each areola and, of course, her highly sensitive nipples. Her chest is sucked, squeezed, kneaded, pinched and tormented until its sensitivity goes completely haywire. As her breasts constantly change shape under the relentless attention, the session builds into specialized sex designed to make her cum through intense breast stimulation.
