My wife Karen has a niece named Leslie. She's 21 and still lives at home with her mom, my wife's sister. They live a few hours away and Leslie will sometimes come stay for a week or so during the summer because we live on lake Texoma.
My wife Karen and I are in our 40's. Our only son has married and lives several hours away now so having Leslie staying a week or two in the summer is a welcome addition as we all get along great.
Leslie is a very curvy girl who still looks quite young even for her age. She's about the same height as my wife at around 5 foot 6 with brown hair just past her shoulders.
As I mentioned she is a curvy girl so she has thick thighs, a round ass and tits that everyone has to be noticing.
Leslie isn't a party girl. She attends a community college where she lives and never causes any trouble. She doesn't act like a kid and she's easy to talk to.
My wife works in an office but she can take care of guite a bit from home, which is what she does most of the time when Leslie stays with us. They'll go to the lake together almost every day and we'll usually cookout most evenings after I get home from work.
My wife seems to be in a better mood when Leslie is here but she'll also tell me it's hard to keep up with the energy of someone half her age, most nights Karen is out like a light by 10pm.
Leslie will usually be wearing shorts and t-shirts in the evenings. I know she wears a bikini during the days, but by the time I get home she has changed. I know it's wrong but I secretly wish she would leave the bikini on.
One evening after Leslie had been over for the better part of a week, we had all eaten and mixed up a batch of margaritas. We were watching a movie and it got a little late. My wife said goodnight and headed for the bedroom with me saying I'd be right behind her.
Leslie was on the couch and I was still in my recliner. The movie had all but lost our interest with both of us just kinda staring blankly at the t.v.
I started talking with Leslie, asking if she was having fun, getting her fill of the lake, etc.
She replied that she was having a good time, but then added that she missed her boyfriend.
I told her I could understand that. I asked if they called or text while she was here, figuring they had to be but I never really gave it much thought before.
She said they do but usually after he got off work at 11:30pm. She then added that her phone had been getting bad reception lately.
I told her she was more than welcome to use the landline but there's only one in the living room as we kept it for use as a fax for Karen's work.
At this point it was almost 11 pm, and as I had to work tomorrow, I was headed to bed. Leslie was still on the couch with the t.v. going when I left.
I fell asleep quickly in bed but only slept a few hours like I usually do. Most of the time I use the restroom, get a drink and go back to bed. When I woke it was 2:30 a.m. Nothing unusual. I didn't need to pee as I usually do but I was thirsty. I made my way toward the kitchen which was down the hall from our bedroom. As I got to the kitchen I noticed a faint light in the living room just off the kitchen. Figuring Leslie left the t.v. on, I went to turn it off. That's when I heard it. The house was extremely quiet except for the hum of the refrigerator, but I heard something else. It sounded like a light moan. Like someone would make with their mouth closed.
I froze, intently listening now, listening for what I couldn't believe I heard the first time. I waited, with my breath held not moving a single muscle. Silence, nothing.
Just when I thought it was all in my head, there it was again, another light moan.
Our kitchen has two doorways going to the living room, one on each end of the same wall. You can't see from one room to the other unless you're standing in one of those doorways. The hall going to the bedrooms is at the other side of the kitchen.
Here I was standing in the kitchen, not believing what I just heard, yet dying to hear it again. And again, silence. The fridge had shut off and it was deathly quiet. I could hear my heartbeat.
Then I heard it again, another moan, and movement on the couch. There's only one thing that could be. I strained to hear more and all the while my dick is growing in my boxers, getting harder by the second.
There it was again, rustling noises, like someone rolling over in bed. Then I heard a wet sound. No fucking way. I crept closer to the doorway careful not to make a sound. I can almost see into the living room, but dare not, not yet anyway.
I can barely hear the couch springs, Now there's absolutely no mistaking what's happening right out there on that couch.
I listen a bit longer, more wet sounds, more very slight moans, and now the couch is making a distinct repetitious, almost squeak noise.
I also realize my hand is around my cock which is now sticking through the front of my boxers. I don't even remember pulling it out.
I am as horny as I've ever been, slowly masturbating in my dark kitchen in the middle of the night listening to my niece who is obviously doing the same thing on the couch.
Several times I have to let my cock go or I would've cum on the floor. With all that I was hearing I couldn't keep from grabbing my hard dick, but as soon as I did I was about to cum and would have to stop, with it bobbing up and down all by itself, dripping precum.
I couldn't wait any longer. I slowly looked around the edge of the doorway into the living room. Oh my god. There was Leslie, laying on the couch with what appeared to be nothing but a t-shirt on pulled up just above her waist. Her head was tilted back, eyes closed, mouth open. Her knees were pulled up and apart with that faint t.v. glow on her tanned thighs and side of her ass.
She had both hands down between her legs, exactly where I couldn't see from my point of view, but I had pretty good idea.
I was beyond horny now. I figured I could get a little closer to the action with her eyes closed like they were. I slowly took a step, then another, and another. I couldn't think of touching my dick now for fear of blowing cum all over the place if I did.
I made my way toward that couch one agonizingly slow step at a time. I could really hear her breathing and the squeaks of the couch as I got closer, but one thing I really heard was the wet squishy sounds her fingers were making with her pussy.
Leslie was getting more into it, pushing her ass up off the couch now like she was being fucked. I got close enough to see her fingers on and in her pussy. Her smooth, wet pussy. My cock was again bobbing up and down all by itself dripping on the floor. Damn, this was so fucking naughty. And I was seriously about to cum just watching.
