A serious-looking innocent high school girl cums like crazy! A cock covered in aphrodisiac slides her panties aside from behind as she is seriously choosing a reference book, and then it's inserted right away! Before she can resist, she starts to feel it, and her legs start to tremble as she convulses, rolling her eyes back as she cums like crazy! A quiet-looking loli high school girl, two black-haired honor students, and a serious high school girl who works part-time at a bookstore.
