Doing my niece

I was living an uneventful life as the owner of a small ice cream parlor in the middle of a south-Chicago suburb. That is, until the day I was able to realize my wildest sexual fantasy. See, my sister Kelly sent her daughter Tina out to the suburbs every summer (so that I can get some free help she says, but she really she just wants me to take her daughter off her hands for three months). Anyway, I have been watching Tina blossom more and more each year into a beautiful young woman. In fact, with her perky C-cup breasts, tiny waist and deliciously round ass, she could easily be a swimsuit model. I had never really looked at her that way until she turned 14, and for the two years since, I’ve jacked off to mental images of her sucking on my cock and begging me to fuck her tight little asshole.
As I anticipated her arrival that summer, I started doing push-ups every morning, hoping to get leaner by May. When she finally moved in, I found things had changed. When Tina was little, she worshipped me. She followed me around everywhere like a little puppy dog and wanted to help me out with everything I happened to be doing at the time. That summer, her attentions had shifted focus to Bruno, this local college kid who worked at the parlor part-time. They kept nudging and flirting with each other at work, while I said nothing and just kept selling ice cream cones. “She’s not interested in you anymore, old man,” I told myself.
Well one day, I noticed that I hadn’t seen the two of them for quite some time and when a group of customers finally left, I walked back to the storage room to see if they were sneaking in a break. I found the door to the storage room slightly ajar and sounds were coming from the other side. It sounded like moaning and I decided to peek in quietly. To my amazement, me little niece was sitting atop a pile of boxes with her shirt and bra pulled up over the tops of her breasts, exposing the most succulent tits I had ever seen. She gasped and arched her back as Bruno sucked on each of her nipples. He was kneeling between her legs, his hands moving up her thigh and raising her short tennis skirt up past her hips. From my view, I could clearly see the wet patch on her cotton panties and felt my penis growing with excitement. I watched as Bruno pulled the wet cloth to one side and began massaging my niece’s swollen clit with his thumb. I unzipped my pants and brought the head of my cock out for air.
