I'm a masturbation geek who masturbates many times a day without fail. One day, I meet my father's new wife, who has an ex-slutty aura about her... she's what we call my stepmother. I start living with her... The next day, while I'm masturbating as I do every day, my stepmother comes into my room unannounced... I don't know what she thought when she saw my dick, but she said, "It's okay if you just lick it." I'm no good, but I have a lot of sperm... I change Kokoro to the meddlesome temptations of my ex-slut stepmother and her sperm-drinking education!
