Tall, slender beauty Riko Miyase is working out when she realizes she has drifted much too close to her instructor—and the exercise has made her horny. He initially resists her advances, but she keeps seducing him until his self-control collapses. She takes his cock deep into her throat in an intensely lustful blowjob, then becomes so overwhelmed by pleasure that she squirts spectacularly. Her supple, perfectly toned body proves just how effective this kind of “sexercise” can be.
