I was covered in sweat and creampied inside me in a closed room during the summer vacation without air conditioning with the plainest literary girl in my class.

The most plain girl in my class. I'm always reading books and have never said a word, but it's really bothering me. I saw this girl masturbating in the library. She peers in a slurping corner of the library, which is not air-conditioned, and sweats her pussy. I looked at me secretly and was excited, and my eyes met... "Did you look at me?" Then my secret relationship with her begins. The summer heat drove the two young people crazy and they repeatedly creampied intensively.
