It all started when my niece came to live with us for the summer. Jaylyn was my sister's oldest daughter and she had just turned 18. My sister lived next town over and asked if it was ok for Jaylyn to live with my wife and I for the summer because she got a job as a waitress close to where we lived, would be easier for her to get to work. We agreed as Jaylyn was a great girl and very mature for her age, so it was no trouble at all.
At the time I was happily married to my wife of 15 years. My wife and I were both 40 years old and though we were happy together things had really slowed down in the bedroom the last couple of years. I'd consider myself a decent looking man 5'11 190 lbs with brown hair and brown eyes. I had gotten some grey hair recently in my hair and my beard which I always kept well groomed. I did sometimes get some attention from younger women, but I never strayed from my wife, though the thought of an extra marital affair did go through my mind sometimes. Especially when I would see a girl at the mall with a nice smile, big tits and wearing tight jeans. Always been sucker for a big firm ass in some tight jeans.
The day Jaylyn arrived at the house I was the only one home. When I answered the door Jaylyn greeted me with a smile and a big hug
"Hi Uncle Bobby"
As she pulled me in for a tight squeeze. I was surprised what I felt on my chest as her what seemed like C cups breasts pressed against me. She had grown into a very beautiful girl. About 5'7 with a beautiful smile, shoulder length brunette hair which she had tied back in a ponytail. She wore a white tank top which showed off her firm tanned stomach. As she hugged me, I could smell her fragrance and it smelled very good.
"Hey, you, wow you've grown up so much girl, come on let's get you settled in. You know where the guest room is."
I picked up her suitcase as she walked in front of me towards the upstairs bedroom. As she walked in front of me, I could not help but notice the tight blue jeans she had on. They hugged her perfectly shaped ass. Jaylyn was an athlete who played soccer in the summer and figure skated in the winter. This gave her a very athletic build and gave her strong legs and bigger firm butt. I watched as her cheeks moved in her jeans as she walked almost hypnotising me. When we got to the stairs, I could not help but stare as her shapely legs and sweet behind. As she got to the top of the stairs, she turned back to say something and had to have caught me checking her out.
"When is Auntie gonna be home?" she asked as she turned to look at me.
I looked up at her eyes immediately and said, "oh she's at work, should be home in couple hours."
She smirked to herself as she entered the guest room, and I followed her in putting her suitcase on the floor.
"Is the pool open?" she asked.
"Yeah, it is, I was just about to go from a swim" I replied.
"Oh good, I'll be hanging out there a lot this summer" she said with a smile "let me out my stuff away and I'll join you out there in a bit."
I went to my bedroom to change into some shorts, my mind racing with dirty thoughts about what I had just saw. I quickly stripped and got out my shorts, I didn't know how to feel about the fact my cock was semi hard with thoughts of my niece's sweet ass. I did tug on it a couple times before getting changed and heading out to the pool.
I walked out to the pool and dove in doing my daily routine of swimming a couple lengths of the pool. I was an athlete when I was younger playing football and baseball, but now the only exercise I get is swimming which I don't mind at all. After a couple laps I rested in the shallow end enjoying the cool water on my body. I then turned as I heard Jaylyn's voice.
"how's the water?" she asked with the smile.
I looked at her and could not believe what I saw. Jaylyn was wearing a black two-piece bikini. Her skin glistened in the sun as I could not help but notice her sexy frame. The bikini bottoms fit snug around her voluptuous hips, I could see the slightest hint of two upper abs on her firm stomach and her bikini top held back what looked like perfect teenage tits.
"It's nice, come on in" is all I could say as tried to look away.
She entered the pool and started swimming around in the shallow end as we chatted a bit how things have been going with each other. She swam down the deep end and started to climb out of the ladder. What I saw next made my cock jump. As she climbed up the ladder, I noticed that her bikini bottom was a thong! Oh my god did it look sexy. She made her way out of the pool and toward the diving board. Her sweet cheeks were in full view to me, and I could not take my eyes off her. She got to the diving board and dove in, swimming under water to shallow end where I was.
"Been a while since I did a dive in the pool, hope it didn't look to bad" she laughed.
"Your form looked good to me" I replied.
"Really, I want to see what I look like when I dive. You have your phone? Can you record me?" Jaylyn asked.
"Sure, it's over on the chair" I said as I got out of the pool to grab my phone.
Jaylyn also got out of the pool as I hit record watching her walk towards the diving board. She did another dive into the pool with me recording. Till she came up
"How was that" she asked.
"You'll be in the Olympics in no time."
"Text it to me please, I want to see it."
She told me her cell number and I trimmed the video a bit, texting the just the dive to her.
Just as I sent the video my wife walked out to the pool and said I hi to Jaylyn. I walked over and gave her a kiss as I head into the house to get changed. I dried off and changed and peeked out to see my wife and niece talking by the pool. I grabbed my phone laying back on the bed and opened the video I had just taken of my niece. I watched her walk by the pool and focused on that booty moving up and down as she walked. Damn she was hot! I felt my cock getting hard and I reached down feeling my hard cock. I watched the video over and over as I could not help it. I pulled out my cock and began to stroke it thinking about Jaylyn young tight body. I then let go a big load as I watched that ass. I immediately felt ashamed of my self and cleaned up quickly.
The next day I could not get that video out of my head. Damn I felt weird about it. I was on the couch watching tv when Jaylyn got home from work. She was wearing a red t-shirt tucked into a pair of black leggings that left nothing to the imagination. She said hi and took off her shoes.
"My feet are killing me, walking around all day is rough Uncle."
"Aww you poor thing, do you need a foot massage?"
"Ahh yeah"
And Jaylyn come and sat beside me propping her feet up on my lap. I took off her socks and began to rub her feet.
"Oh, that feels so good Uncle, I needed this so bad" she said.
I massage the bottom of her feet as Jaylyn laid back and closed her eyes. My mind wandered again as I though back to the video of her in her bikini and her sweet ass cheeks. I could feel my dick twitching and I shot back to reality when I heard her moan.
"Mmmmm yesss" she let out.
That moan sounded so sexy. I rubbed a bit harder.
"Ahhhh damn that's good, you're such a sweet Uncle."
After a few more minutes Jaylyn excused herself to take a shower.
My wife got home a few minutes later to cook dinner.
The next day Jaylyn and my wife were out by the pool, and I was emptying the laundry hamper to take a load of laundry to the washer. I didn't have enough clothes for a full load, so I went into the guest room to do Jaylyn's laundry as well. When I opened the laundry hamper, I saw a pair of red thong panties at the very top of her dirty clothes. The thoughts that went through my head. I picked them up and imagined how sexy my niece must look in these. I couldn't help it; I brought them up to my face and inhaled the sweetest aroma I had every smelled. The scent of my 18-year-old niece's pussy. Damn it turned me on and my cock was rock hard immediately. The held the panties to my face with one hand and rubbed my cock with the other. Fuckkkkk I was horny. I then pulled out my cock and used her dirty panties to stroke my hard cock. I did not last long as I shot my load onto the floor. I quickly cleaned it with a towel and grabbed all her laundry and went downstairs to the put all the clothes in the washing machine.
Friday came and my wife was going to a weekend spa getaway with some of the women from her office. My wife left around 5pm Friday evening and left meat home for the weekend with Jaylyn was at her job until 10pm. At about 10:30 I was in my room laying on my bed when I heard the front door open, so I assumed Jaylyn was home from work. I heard her go to the guest room for a bit then back out to the living room. A few minutes later I heard a beep on my phone from an incoming text, it was from Jaylyn, and it read.
"Uncle, my feet hurt. Can you come rub them again pleeease 😊"
I read the text and smiled to myself.
"Aww my poor niece need uncle to make her feel better?"
"You have no idea how much I need you to make me feel better...please uncle."
"Ok ok, will be right there."
I made my way to the living room and Jaylyn was lying on the couch on her stomach. So of course, the first thing I noticed was her big firm butt cheeks. She was wearing a little white tank top and the smallest pair of baby blue booty shorts. I could just barley see the bottom of her cheeks below her shorts. Jaylyn looked over her shoulder at me and smiled.
"Am I ever happy to see you" as she stretched her feet out towards me.
I sat down with shins resting on my lap as I began to slowly massage her feet. It wasn't long Jaylyn was letting out those soft moans again.
"Mmmm that feels sooo good, I couldn't wait for my shift to get over so you could do this uncle."
"Haha just glad to be of service sweetie."
"I needed your services so much Uncle Bobby."
I massaged her feet and pushed up a bit to her calves.
"Your calves feel pretty tight, they need to be rubbed too" I asked.
"Yes, my legs get sore everywhere at work."
My hands slid up her to her calves as I pushed my thumbs into the middle of her calves. I must have hit some sore muscles there as she tensed up a bit cause her body to shake slightly. As she tensed, I watched her booty cheeks shake ever so slightly.
