The women came to shoot a swimsuit image video to earn some extra cash. However, the content turned out to be a sumata (intercrural sex). Huh? Sumata?? They were confused, but they started doing it for the money. Struggling with the unfamiliar movements, they gradually responded to the increasingly extreme demands, and as they did so, they began to feel good, and eventually they were penetrated. They were confused at first, but their bodies became so sensitive from the sumata that they couldn't stop!
