My younger sister Kelly has been getting bad grades lately since her soft supple breast have grown in and she doesn’t know what to do about it. If she doesn’t get her grades up my parents are going to lose it with all the cash, they shed out each and every month for the little brat’s education. Kelly got another D and I can’t take it anymore I’m going to have to talk to Professor Davis I will do anything to help her get her grades up. Mr. Davis, I hate that my sister’s grades are slipping and I’m afraid that she may flunk out. I really need to know what I can do to get things back together for her. “Well Kelly, her parents have worked very hard to pay for the best education for her, I think she hasn’t been applying herself to the fullest, and she will have to allot of work to make it up.” There was a strange thing happening though when professor Davis was talking to me his cock seemed to get so hard in his pants. I felt like I could do some extra credit work for the little slacker to get her grades up. I was about to show professor Davis how badly I wanted and needed to help my sister get an A and after I finished with the professor he was going to be giving my little sibling good grades from then on.
