It's not easy being the step-father of an 18 year old college girl. Fortunately for me, I'm not the one paying her tuition, her real father takes care of that. So imagine my surprise when I got a phone call from the Dean's office, asking me to come pick up my step-daughter from school. It was the middle of the day, and I had to leave work to go get her, so I was rather pissed off when I found out that she had gotten caught doing something that her mother would beat her for if she found out. It seems that her daughter was giving a boy a handjob and was busted in the janitors closet during class! The Dean was threatening to expel her for her action, and so far I was the only parental unit to know what was going on. I hadn't told her mother that I picked her up yet, but was planning on breaking it to her when she got home from her job. During the ride home, not a word was spoken. She knew she was in trouble, and I think she was trying desperately to think of a way out. We walked into the house, and my daughter immediately began to apologize to me, and beg me not to say anything to her mom. She told me that she had given a boy a hand job, and was so good at it that word began to spread around campus. She had apparently gotten the reputation for giving the best hand jobs and had a line of guys waiting to get their cocks between her palms. She's a pleaser, she said, and enjoyed making guys feel good. I could tell she was scared of her mom finding out, which is why she suggested that we could have some sort of arrangement. If I promised not to tell her mom what happened, she would demonstrate her hand job skills on me! I was reluctant at first, but it had been a long time since such a cute young girl had her hand on my shaft that I couldn't say no. She's basically a good kid, and doesn’t deserve to get in trouble for such a small thing. I let her lead me into our bedroom to show me how she had gotten such a reputation. I laid down on the bed and let my daughter take control, she was the expert apparently. She unbuckled my pants and saw that my cock was already half way there. She took my dick in her cool, smooth hand and began to stroke me. She said my cock was the biggest she'd ever had in her hands (and she had a lot of dick in her grip). She was willing to do anything to make me feel good. She took slid her top down and took off her bra, showing me a pair of the firmest 18 year-old breasts I could ever imagine. Her tits were perfect! My cock got even harder when she said that when she was jerking off the boys at school, she was really imagining that it was me she was pleasing. She had been thinking about my cock for a long time she said. She took off her panties to show me how wet she was getting from stroking her Dad, and that because it was so wrong, it was an even bigger turn-on for her! She gave me a nice long look at her pussy while she rubbed my spit-lubed cock. "Do you like when your little girl spreads her legs for you, Daddy?” she asked me, with half lidded eyes. I could see how filled with lust she was becoming. "You should punish me with this big dick, Daddy. I think I need to be penetrated”. "Come on Daddy, cum for me”, she implored me as she increased the speed of her cranking. I felt an enormous rush as a huge load of cum shot out of my cock to cover my daughter's tits. She spread my jizz over her tits, rubbing it into her hard nipples. "You made a mess on your little girl, Daddy. Remember to keep our little secret. We better clean up before Mom gets home."
