The "bonus footage" of "Can we have sex without being noticed by the co-stars and staff during filming?" has finally been added to the main feature! Asada Yuri, Ikumi Kuroki, and Minori Kotani take on the challenge while other people are filming! Don't miss the real excitement and the serious sex while trying to hold back their voices because it's serious. The sense of immorality is the best stimulant!
