My neice Darla

My infatuation with my neice Darla began when she was only ten. I was looking at the age of 33 and my wife had left just a month ago. Darla is my wifes sister Kimberly’s oldest daughter. Darla has an olive/tan skin tone with shoulder length light brown hair. She has a rose colored tint to her cheeks as if she’s always blushing and the same color to those plump lips of hers as well. She has this sassy little attitude with the voice of an Angel.
Darlas breast have began to fill out. They are puffy around the nipples and from what I have seen lately , when erect her nipples are an inch long. That ass of her’s just screams ripe, firm and perfectly round. My cock grows hard looking at it . There is something about the way she looks at me lately that just makes me want to slap her in the mouth with my 9 in. cock.Kim and Darla only live 2 doors down from me and Kim drinks all the time so Darla stays at the house alot playing with my boys. I find myself watching her out in the yard with my cock out. She’s turning cartwheels in those damn little sundresses she’s been wearing lately, not even trying to cover herself.Does she know what she is doing to me?
The boys were riding bikes and I heard Darla say I am going to pee boy’s and don’t you dare follow me and I mean it , I heard her tell them as she headed around the corner of my shop. I noticed as she looked back over her shoulder to make sure no one was coming. As I stood there jacking on my cock thinking of her little ass in those baby blue panties flipping through the yard, I realized she had been gone awhile. I decide to go check on her. From the top of my shop I have a clear view of everything . I see Darla squatted down in a thicket with a book. What kind of book is it? I couldn’t believe what I was seeing. She had my favorite porn , her purple dress hiked up to her waiste, her bald pussy exposed as she fingered it fiercly. She was pushing her index finger about 1/2 way in and out of her obviously wet pussy. My cock jumped to full attention at the sight of my sweet little Darla.I closed my eyes and After pulling on my cock with 3 strokes I was shooting hot jizz all in my underwear.
Uncle Tommy what are you doing? Darla was behind me. Had she seen me watching? Did Darla know I was jerking off watching her play wit that bald pussy of hers? I am about to start spring clean up on the shop today.
