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
