Hump Bang! - Episode 2

Hiro continues her submissive relationship with Kouji, wearing a collar and engaging in fantasies of group sex. After her fantasy, Hiro encounters her friend Rin at school, who admires Hiro's collar. Kouji forces Hiro to masturbate in front of him, and Rin watches, getting aroused. Kouji then compels Rin to participate, performing oral sex on her and eventually penetrating her pussy while Hiro watches. Rin, admitting her own perversions, enjoys the experience and even challenges Hiro to match her performance. After Kouji cums inside Rin, Hiro is returned to her duties as Kouji's human toilet.
