Devastated after her brother’s death and the discovery that he ran off with someone else’s money, Maki Koizumi tells a debt collector she will do anything she can. He makes her expose her body, kneel, and wear a collar before ordering her to masturbate with a vibrator. Taking advantage of her kindness, he demands a blowjob and titjob. Maki eventually mounts him and lowers herself onto his cock, rocking her hips and bouncing her huge H-cup breasts as she climaxes repeatedly. In the end, she submits completely and accepts a creampie.
