A married woman named 'Yuka' who lives in the same apartment building. Every morning when we greet each other, we become friendlier and eventually have a physical relationship. Yuka hasn't had sex with her husband in a while and has an excess of sexual desire, so she enjoys having sex with him every day when her husband is not home. At one point, 'Yuka' suggests, "How about we secretly record ourselves having sex?" She asks her friend to help with the recording or they do it themselves with a smartphone! Perverted Yuka gets even more aroused!!
