The Tokyo Metropolitan K Gakuin Girls' Club requires students to submit a ``penis observation diary'' as part of their extracurricular classes. Please enjoy the expressions of high school girls, such as those who are surprised at the difference between the squishy state and when erect, and those who witness the glans and neck at close range and are impressed by the detailed structure. We will touch, smell, lick, stimulate, and thoroughly observe the amount and taste of the sperm after ejaculation, and observe the penis in various ways.




















There aren't that many cute girls, but Ayumi Sena's handjob scene in a school uniform was good.
This is a decent work for those who enjoy handjobs from girls in uniforms. Some actresses sniff, lick, or even take it into their mouths, so there's plenty to choose from depending on your taste. There are a few cute actresses in the cast, so picking based on the performer is a valid strategy. I was hoping for more dirty talk or erotic commentary, but it felt more like a literal observation log—measuring dimensions and making comparisons—so it was a bit underwhelming. Giving it a low rating.
*If you like CFNM or like the curiosity of girls when you watch them, I think you'll find it quite interesting, but I don't think it's interesting for people who want blowjobs, real acts, or anything more. I quite liked it.
It's almost entirely handjobs. This might be okay if you're into handjobs or are a beginner, but otherwise, not great.
