Little sister Kimmy Part 2

Well as I said in my first story my little sister Kimmy and I spent the rest of that first summer learning and teaching each other about our bodies. The one thing she would not let me do though was actually take her virginity. She had previously had the sex talk with mom and was convinced she would save that part of her for her husband on their wedding night. It seemed crazy to me because she didn’t even have a boyfriend at the time.
Throughout that first summer we did graduate to oral sex. Kimmy became very good at it and at times seemed obsessed by it. She loved it when I went down on her but was crazy good at giving head. By the end of the first summer she was swallowing my cum, and could take most of my young cock in her mouth. In the beginning we were very awkward together because of our inexperience, but we learned quickly. Now, because our mom’s room was right down the hall we had to be real careful, so we would wait until she went out or when she had some wine with her sleeping pill at night…. Those nights nothing woke her up! There were also the occasional couch episodes after mom went up to her room.
Both Kimmy and I dated in the following years, but it didn’t stop our escapades. My girlfriend Connie, in my sophomore year took my virginity and I found I was able to please her quite well because of my tutoring sister! By the time Kimmy was a freshman in high school, she was dating a senior. He was some asshole that I never did like. She wouldn’t fuck him, but as I said, she was real good at giving head, so they dated until she got tired of him and sent him on his way.
That quickly brings us to my senior year of high school. I guess it was in March that I decided I was going into the Army after I graduated. Kimmy wasn’t too thrilled about the idea so sex was very much on her terms. Some nights she would maul me and then I might go 2 weeks where she would barely talk to me. By this time I had become quite popular with the girls in school. (I guess it’s true that girls talk) But I always enjoyed the time with Kimmy more than with any of them. I didn’t have a girlfriend for the last half of my junior year and my entire senior. I would just go out with whomever, and if she put out, I would go out with her again; Sounds pretty bad looking back at it.
That brings me up to a couple weeks before graduation. Kimmy started making comments about how much I was going to like what she was giving me for graduation. I figured she was buying me something because she hadn’t done anything sexual with me for the past two or three weeks. Every time I would see her my cock would get immediately hard and she would shun off any attempts I made toward her. She was growing out of her “ugly duckling” looks now as a sophomore. She traded in her glasses for contacts and was actually starting to fill out her shirts quite nicely. She wore tight jeans that showed off her round ass and I often had to hear from the guys in school how hot my sister was. I would get jealous, believe it or not, but couldn’t say anything about it, so I would often fall back on the “That’s my little sister you’re talking about” line.
The last weeks before graduation were real busy, with getting ready to head out for basic training two days after I graduated; it just seemed like there wasn’t enough time in a day to get everything done. Kimmy wasn’t helping me out and I didn’t date those last few weeks, so no matter how much I jacked off, it seemed like my balls were always full.
The morning off graduation was uncommonly warm. I decided I would wear shorts and a t-shirt under my robe. Graduation was at five and I woke up at the crack of noon. I lounged downstairs and made some coffee and was sitting alone at the kitchen table when Kimmy came down, wearing shorts that didn’t even think about covering her ass, and a tank top with no bra under it. I could see every line of her ripe breast and her nipples were doing their best to rip right through her shirt. As she walked into the room my eyes followed down her shapely body to her bare legs and bare feet. (You know how I love her feet!) “You’re killing me” I mumbled. “Not yet” she countered back. She walked over to the table, and leaning over, rubbed my crotch with her one hand, while she stole my coffee with the other. “Damn” I complained as I pushed myself off from the chair to get another cup. She took the seat across from where I was sitting and I returned to my seat with a fresh cup of coffee.
