(Translated Title: Partner Exchange) Tommy (33 years) and Bonny (35 years) are a very open-minded couple, but they're both finding themselves a bit bored. Bonny is simply too horny for Tommy to keep up. Crissy (35 years) and Rick (36 years) are also found occasionally in swingers clubs and love freely expressing their sexuality. They decide to do a partner swap with each other, and the exchange adventure begins! In video messages, the women describe what makes their men horny and how they prefer fucking. The swap works so well, they end up all fucking TOGETHER in the end!
