The third exclusive work by the stunningly beautiful girl, Riko Shiraha, is from the popular S1 series "Intertwining Body Fluids, Intense Sex." Intense sex between a "man" and a "woman" that is fierce yet gentle, rough yet caring, and that exposes their true instincts. Even without words, their feelings are conveyed by looking into each other's Hitomi. They passionately desire, tease, and confirm each other, and without even taking a breath, the two fall into a whirlpool of lascivious and obscene pleasure. Three scenes of intense sex that exposes their true instincts bring Riko Shiraha to an unprecedented climax!
