On my last summer break before joining the real world, between my Junior and Senior year in college, I decided to go home. I would be graduating next year and I felt I had not spent much time at home since I left a few years prior. I wasn’t exactly on the 4 years and out plan. I would always visit for the holidays, but every summer I would find a job and stay in the same town I was attending college. However, this summer I wanted to spend time with my family, especially my little sister. There’s quite a bit of an age gap between us. I was now 24 and a few weeks prior to my arrival, she officially became a teenager with a year left before starting high school.

I arrived home on a Friday night and hung out at home most of Saturday. On Sunday Jenny and I had already made plans to go hang out at the local amusement center for some miniature golf, go-carts and just get a chance to hang out and get reacquainted. She had invited her best friend from forever, Abby. They were inseparable from the First Time they met each other. Over time, we had learned that Abby never knew her father and her mother had a revolving door of boyfriends. I suppose our home gave her some sort of stability.

When I first got home I had noticed that Jenny was certainly not a little girl any longer. I couldn’t help but notice that she was filling out quite nicely. She was now 5′ 3” and her breast were between an A and B cup with hips that were starting to flare out nicely with a thin waist. She had always had nice full lips that looked even nicer now that she was allowed to use a minimum amount of make-up. I was surprised that my dick actually twitched when I saw her glossy full lips. They looked so fucking sexy.

Sunday morning we jumped into my Ranger truck and swung by to pick up Abby. My sister was wearing cute shorts and a tight tank top that nicely showed off her growing tits and part of her tight smooth tummy with her belly button on display. Whenever I meet the person that invented crop tops, I will kiss their ass. I love the way girls look in them. They get an extra 10 points in the sexiness factor, so long as her tummy is taut. Crop tops, like leggings, are a privilege and not a right.

I had to constantly remind myself that she was my baby-sister when I caught myself ogling her. When Abby came running up to my truck, I was shocked. She too was wearing shorts, only they were tighter and shorter than my sister’s. Her tight little ass looked great! She had filled out more than Jenny. Her tits were a nice full B cup that were covered also by a tank top with no bra that covered only half her tight tummy. Her hard little nipples were on full display. Even as a little girl I always thought she was a cutie, but now she was looking even nicer with full dick-sucking lips.

My sister scooted over and Abby jumped in. She said hello as she entered and we were on our way. She was very talkative asking me how was college and was I enjoying myself. She asked if I had a girlfriend and when I told her not any longer she flirtatiously told me she could be my girlfriend if I wanted. My sister immediately blurted out “You are such a slut. You don’t have to flirt with every guy you meet.” They both busted out laughing and we soon arrived at the amusement center. Strange how she and I barely spoke when she was younger, but now she couldn’t stop talking.

I actually had fun hanging out with two teenage girls. That they were hot looking was a bonus. My dick seemed to be enjoying the eye candy along with most of the guys at the amusement center with their tits and legs on display. It was obvious they were good for each other. My sister was the calm sane one and Abby was the wild crazy one that needed to be brought back down to Earth ever so often. Throughout the day, Abby continued her flirtatious comments, telling me how good looking I was and that if I asked her out she would agree to go out with me in a heart-beat. I played along, telling her how cute she was and that I was surprised she did not have a boyfriend with such a cute little ass. This would prove to me mistake number 1.

We finally called it a day and jumped back into the truck, with her jumping in before Jenny and sitting next to me. I was a bit excited and hoping she wouldn’t notice that I actually had a partial erection. I knew nothing would happen between us, but I suppose all her attention had gotten to me and my ego. Plus, her hard little nipples did not help. I looked over to Jenny and she just rolled her eyes. She was used to Abby’s daring behavior by this point.

When we arrived at Abby’s, Jenny got off to let her out. Abby turned and kissed me on the cheek before leaving, saying thank you for a great time as she winked at me. As we drove home my sister warned me, telling me “You know, she really likes you. She told me she thought you were cute and she wouldn’t mind being your girlfriend when we went to the restroom.” I told her that I assumed she flirted with all the guys she met and I was simply her victim for today. She was cute but she was also way too young for me. Either way, Jenny told me to be careful.

I had gotten home at the end of May and Jenny and Abby still had a couple of weeks to go before their summer started. I sat around the following day and the very next day I was out looking for a job. It was boring sitting around with no one to talk to. Jenny was at school and mom and dad were at work all day. By the end of Tuesday I had rejoined the workforce securing a job at a grocery store. An old high school buddy worked there and he vouched for me with the store manager. I was hired on the spot and asked to report the next morning at 7am. It was part-time, but a great way to get some extra cash and kill time during the week.

Come Saturday, Jenny had asked if I could drive them to the mall. She and Abby would be meeting up with some friends. I told her it was not a problem as my shift did not start until 5 pm. We swung by Abby’s and headed to the mall. It worked out fine for me as I had to pick up some jeans and a new pair of sneakers. They went their way and I went my way, with plans to meet at the food court around 3 pm. I went off and like a typical guy, I was done with my shopping within an hour.

I arrived at the food court half an hour early and waited for the girls so we could eat before heading home. When they arrived, Abby was excited to see me and came up to hug and kiss me on the cheek, asking me “Did you miss me?” as she sat on my lap. I looked over and Jenny simply rolled her eyes. We went over and grabbed lunch before sitting down, with Abby sitting right next to me. I was certainly enjoying the special attention she was giving me, regardless of her age. While we were sitting, I suddenly felt Abby caressing my thigh under the table and remembered being warned to be careful with her. I turned my head to look at her and she simply kept eating and did not bother turning to look at me. I quietly reached down and removed her hand. I was not trying to get myself in trouble.

When we returned to the truck, once again it was Abby sitting next to me. On the way home her hand casually fell on my thigh and I decided not do anything. I wanted to see how far this little girl was willing to go. It went further up than what I expected. Her hand was making its way to my crotch when I finally decided to quietly move her hand away without my sister noticing. We got to her place and both girls got off. Jenny had made plans to spend the night and asked if I could pick her up the following day. I was not scheduled to work on Sunday and told her I would. We hugged and kissed before I left. Of course, Abby also hugged and kissed me on my earlobe, whispering into my ear “I’ll see you tomorrow, lover boy.” with a big smile on her beautiful face before they both made their way up the stairs to Abby’s apartment. That little girl gave me a chubby. I raced home, jacked off, showered and left for work where I ended up working an 8 hours shift due to some people calling out sick.

I got home late and went straight to bed. As much as I wanted to ignore what was happening with Abby and just brush it off as a joke, it had me wondering. Was she simply flirting because that was her nature or was she trying to getting something started. She was definitely trouble. She was a sexy little girl with a pair of great looking tits and a tight little ass that filled out her shorts very well. Her legs looked great on her and she had a cute face with nice lips and hazel eyes. She was probably about 5’2” with long brown hair down to her ass and weighed maybe 110 lbs. She was a nice little package.

As I laid in bed, thoughts of her kept me from falling asleep. I started wondering what she looked like naked with my cock in her mouth between her luscious lips. My cock was hard and my boxer were down by my ankles as I started stroking it thinking about Abby. I imagined her naked on her knees as I fucked her sweet little mouth hard. I was grabbing her hair and pulling her to me as I thrusted forward, with my cock going deep into her mouth, over and over. I hadn’t cum in a long time as much as I did that night. This little girl was going to be my demise.

The following weekend my parents and sister had plans to spend the night out of town. My mom’s younger sister had given birth to her fifth baby and my mom and Jenny were dying to go see the baby, as if they hadn’t seen the first four. My dad went along because my mom told him he was going. I had to work on Sunday and was saved from the three hour trip. My plans were to mow the lawn on Saturday, take a nap, shower and go hang out with some friends from high school. There was gonna be all sorts of people from our class and I was excited to catch up with some of them.

I finished the backyard first. As I was working on the front lawn, I saw Abby stepping out of a car before it quickly drove off. She was looking fucking hot! She had a very short skirt that I’m sure would show her panties if she bent over and a tight top that was showing off her perky teenage tits and her hard little nipples. I was shirtless, only wearing shorts and my sneakers. As sweaty as I was, she came up and gave me a peck straight on my mouth saying “Hi lover boy. Where’s Jenny?” She knew damn well that Jenny was gone for the weekend. I played along and told her she was gone for the weekend, asking her if Jenny had not told her. She suddenly “remembered” and asked if I could give her a ride home. I told her she would need to wait until I was finished.

She kept me company as I finished the yard, following me around and asking if I liked how she looked, telling me she had dressed up extra nice for me. I told her she looked very pretty in her outfit and if she was older I would probably ask her out. Something I never should’ve said. This was mistake number 2. I am sure it gave her more confidence in what she was about to do.

I finished the yard and we went inside. I fixed us some sandwiches and we had lunch, with her relentless flirtatious comments on what a good girlfriend she would be for me. Thoughtlessly, I asked what she would do to be such a good girlfriend. This was now mistake number 3, of course in baseball this is it. When she started talking about oral sex, I cut her off and told her I would be taking her home after my shower. This would be the nail in the coffin.

After exiting the shower, I walked to my room to find her sitting on my bed. All kinds of scenarios came to my head, which caused a very noticeable tent in the towel wrapped around my waist. I asked what she was doing in my room and, unconvincingly, told her to leave. She looked at my crotch and asked if I really wanted her to leave. I was not thinking straight as she approached me.
