I don't have a girlfriend. But I have a huge sex drive, so I spend my days sloppily masturbating all the time. Then one day, my parents remarried and I got a stepsister. She's cute, but super meticulous! What's more, she complains that I'm sloppy because I masturbate too much, and even tries to control my ejaculation!? I thought I couldn't take this life anymore! But then my stepsister, while making sarcastic remarks, started giving me a handjob... And not just a handjob, but penetration too!? I'm now living a life of being strictly managed by her top-notch management skills.
