Izumi Miya makes her HEYZO debut with her gorgeous big tits. She lies to her husband and takes a hot-spring trip with her lover, quickly showing off her beautifully shaped breasts in the mixed bath. With other guests liable to walk in at any moment, he can only sneak a quick lick before they retreat to their room. After a few drinks, they dive into a full-blown affair with sloppy kissing, breast play, oral sex, and fingering that leaves her pussy soaking wet. She even sucks his cock while talking to her husband on the phone without getting caught. Relieved that the secret is safe, she takes his cock inside—only for her husband to call again while she is lost in pleasure.
