Sumire is an 18-year-old student who can't refuse her boyfriend's request to develop her anus. She is a third-year student in the ping-pong club, but her anus is so dilated that a ping-pong ball can fit inside her anus better than the opponent's net. Whenever I put it in, it is always raw. And I like it so much that I squirt in the anus. Sumire, who is a confirmed keto-anal at this age, is going to be a confirmed whore for the rest of her life.
