SP-435 - Thrilling Affair Trip 2: 47 Days of Non-stop Hardcore Action

As an AV, the scenes are short, there's nothing acrobatic, and the actress isn't exactly top-tier. You have to watch this as a documentary to appreciate it. The point is that she's not a professional AV actress, but a student aiming to make films, and she participated in this project despite having a boyfriend. At first, she treats it as just finishing a project and seems to enjoy the sex, but then a gradual shift occurs. Reading that psychological change is the real thrill of this piece. Knowing that she actually became a film director now makes it all the more poignant.
