【The Empress of live-action adaptations of the super popular doujin comics by Aomizuan & Hakuginean, Hana Himesaki, makes her first collaboration!】 Once-a-month, bland sex with a condom... A lifeless newlywed life spent while hiding my true "ultra-sadistic" nature... That was my daily routine... As a doujin game creator, I began recruiting for an eroge voice actress for my third work. Then, a girl contacted me... Her name is "Koharu Haruno". Features that rival celebrities, breasts that put gravure idols to shame, a voluptuous big ass, and a cute, fresh voice. And she is an even bigger fan of my work. Possessing all the charms of a female, during the recording, she kneads her own breasts, licks her fingers, and makes a request that makes me question my ears... "Could you please choke me...?" (Is this girl inviting me...??) The moment I tighten my grip on her neck, she reaches a squirt-climax. Facing this "female" who scatters the scent of nymphomania throughout the room, the man becomes certain. "This girl is a true masochist..." "Please make me your Master's pussy voice actress..." The "ultra-sadistic" nature that had been suppressed in daily life explodes, and the two engage in an obscene, animal-like infidelity.
