Anri and Yuki sit on chairs with tense expressions, their bodies stiffened. Their eyes mix frustration and desire, making one wonder what they truly crave. Standing before them, a man forces the women to deliver fierce slaps to each other. Tears well in their eyes and their bodies tremble, yet their hands instinctively drift toward their crotches. Slap masturbation, lesbian slapping, ass slapping, breast slapping, slap sex—these deeply masochistic women reach extreme pleasure solely from being slapped. Their bodies quiver with each strike, perfectly embodying the very moment of orgasm.
