My son Takeshi is a ronin student who looks cute, but shows absolutely no sign of trying hard, which worries me. Today, he said he was going out for a bit, and when I asked where, he told me he was going to buy adult magazines. I got a little angry and grabbed the magazine myself. I should have just stopped there, but as I looked through it, I became aroused and ended up masturbating. I felt truly ashamed of losing control like that. However, I never expected my son would end up seeing the whole thing...
