A sexually perverted couple resorts to cuckolding. They barge into an adult video studio and beg to let anyone insert anything into their lover's genitals. Tohru, 30, and Rika, 22. She decides to let a stranger embrace her boyfriend in front of them, wanting to support him if that's what he wants. Even so, she flinches as he caresses her and asks, "Is it okay?" She can no longer hide her embarrassed smile until her vagina is fondled and her breathing becomes heavy. She can't help but climax with a vibrator, muffling her voice. She sucks the other man's cock with all her might, and lets out a sexy cry when he penetrates her while she's standing. She has a spasmodic orgasm as her clit is played with on the desk, and then continues to climax with convulsions as the position changes.
