My Naughty Niece.

When my wife and I were in our late twenties we'd been in the swinger lifestyle for about ten years. We'd go out of town almost every weekend to give my wife the chance to expose herself to stranger, pick up people for threesomes or small gangbangs or hook-up with couples we'd meet through swinger magazines. But when my sister called and asked if her 15-yo daughter could stay with us a few weeks we were more than happy to oblige. Even though we knew it meant we'd have to put our swinging on hold for a few weeks.

When Cindy arrived I was shocked at how much she'd changed since the last time I'd seen her several years before. She was about 5-10 with long sexy legs & long blonde hair and had really started develope being about a 34B-24-36 with piercing blue eyes and full pouty lips. Looking much older than her actual age. And I couldn't believe how she was dressed wearing a button-up blouse that only had about 2 buttons buttoned and tied in a knot exposing her firm tummy. With a pair of cut off jeans that didn't come close to covering her sexy young ass.

And her attitude really took me by surprise also. We had a swimming pool in the back yard and she just came right out and asked my wife Lynn if she ever went skinny dipping in the pool? It took Lynn off-guard and she told her she had, immediately realizing she should have said no. And Cindy said she wanted to try that later. I was in the other room listening and will admit my cock was getting hard as in my mind I pictured my hot young niece naked splashing around in the water and fantasizing about bending her over the side of the pool & fucking her tight young pussy.

I couldn't believe how bold she was when she asked Lynn if the 3 of us went skinny-dipping she hoped we wouldn't tell her mother. Lynn still shocked by the conversation as well as being a bit turned-on herself at the idea of seeing our niece naked assured her we wouldn't. But the surprises didn't stop there when Cindy commented on what a nice body Lynn had and said she was looking forward to seeing her without any clothes on. My cock was like a piece of steel by that point. And I kept expecting Lynn to suggest maybe Cindy wearing one of her sexy bikini's but she never did. I think she wanted to see Cindy naked as much as I did.

We couldn't wait until that night and once it was dark the three of us went out with robes on but once we got to the pool that was hidden a little by a short fence & shrubs we took of the robes and got in the water. Cindy seemed totally at ease being naked in front of Lynn and I, and was again commenting on Lynn's sexy 5-8, 110lb, 34D-24-35 body. And even commented on my thick 9 inch cock telling Lynn she could see why she always seemed to be so happy. But again she shocked us when she asked Lynn if when she sucked my cock if she was able to swallow all of it? And said she'd never sucked a cock that big. It was hard to believe she had just turned 15 a couple of weeks before.

I was starting to get hard again and I know Cindy was noticing it. But when she commented on how firm Lynn's tits looked and asked if she'd mind if she felt of them I was going nuts. And she didn't wait for Lynn to answer her and instead just started to grope her aunt's big tits as she told her how good they felt and asked Lynn to feel her's. Lynn knew she shouldn't do any of this but she couldn't resist and started to squeeze our nieces tits. And soon they were running their hand all over each others bodies and kissing. Then they started sucking each others tits. I was turned on watching them together, but being outdoors with houses all around us and knowing if someone walked up on us we'd never see them but they'd see us because of the underwater pool lights.

I wanted to suggest we go inside but wasn't about to take a chance that it might stop the action and they wouldn't do anything inside. Especially when Lynn had Cindy sit on the side of the pool and started eating her pussy. I couldn't resist and moved closer and started rubbing my hot little nieces long sexy legs and worked my way up and started fondling her firm young tits and working her hard nipples between my thumb & forefinger. Then I felt her foot rubbing my hard cock. I got on the edge of the pool sitting beside her and started sucking on her tits as she was stroking my hard cock. I couldn't resist and stood up and pulled her head toward my rock hard cock and she didn't hesitate in taking it in her mouth. I knew there was a chance someone could see me standing there but all I cared about was fucking that sweet little mouth.

It was obvious she had some experience sucking dick because she was doing a fantastic job. She wasn't able to take all of it. But between her sucking my cock & balls and jerking me off I was on the verge of exploding. I thought about shooting off on her tits, but damn her mouth felt so good. So I put my hands on the back of her head and started skull fucking that hot young thing. I shot a huge load in her mouth that would choke most girls but she swallowed every drop and started licking up & down my shaft and around the head. By now Lynn had gotten Cindy off a couple of times so I figured it was Lynn's turn to get some relief and when I went to slide back in the pool Cindy leaned over and whispered in my ear that she couldn't wait until I fucked her and said she hoped it happened soon.

By now I was getting my second wind and was going to fuck my wife and as I started fucking her Cindy came over and started sucking on my wife's big tits and talking about a girl she'd been with who had huge tits, but said she preferred Lynn's tits. It didn't take long for Lynn to have an orgasm and we were all pretty spent. I couldn't believe it when the girls ran back to the house bare ass naked where anyone could see them so I said fuck it and did the same thing. We stayed naked the rest of the night as if it was nothing out of the ordinary. Over the next couple of weeks we had several threesomes with our niece and I fucked her in every position I could think of. But it was clear she was more into Lynn than me. But that was cool too since I got to watch.
