What would happen to a woman if she had sex from morning till night? This project is based on that question, and it's all about having sex. H-cup busty Sanae Shingetsu makes an appearance! Her sensitive nipples make her body spasm every time they're pinched, and when she's penetrated deep inside, it feels so good that she pees and cums over and over again, and in the end, she even asks for a creampie!
