I saw a cute girl named Rika on the street. I thought she was a little too young, but she's actually an adult with a boyfriend who intends to marry me. I hit on her, and the atmosphere got good, so I negotiated with her to appear in an AV. She agreed to appear in an AV and have raw sex without any problems. Three months later, I got a shocking message from Rika... And then I had creampie sex with a young married woman who had started producing breast milk. This is a documentary film that took place over the course of about a year.
