My brother and his wife went on vacation and asked me to keep and eye on the house and their 19-year-old son who has a summer job and had to stay home.

On Friday afternoon I finished work early and decided to go check the house and go for a swim while I was there. I pulled in the driveway, parked the truck, and headed around the house to the back gate. As I approached the gate I could here the sounds of sex coming from the pool area. I eased around the corner of the house and could see my nephew having sex with an extremely good-looking young lady on the diving board. Her legs were wrapped tightly around his waist as he pumped her for all he was worth.

Her firm tits jiggled each time he drove into her. I could here the slap of his thighs against her soft place with each stroke. Barely audible moans escaped her lips from time to time, her eyes were closed. Mike withdrew from her steaming box and proceeded to go down on her. She grabbed his head with both hands and said Oh yeah baby eat my softness, you know I love that.

Mike toyed and sucked on her extended personal place flicking it with the tip of his tongue and driving her wild with pleasure.

He slid up her body positioning his length at the entrance to her waiting slit. Slowly he slid his entire length in and started to play her again.

After about a dozen strokes he pulled out, straddled her body and blew his load all over her heaving tits. She spread his cum all over them and toyed her fingers clean.

She looked at him and smiled That was great babe absolutely great. I slowly and quietly backed away from the gate and went back to the truck. I opened the door quietly and slammed it hard enough for them to hear.

Then I slowly walked around the house t give them time to get dressed.

When I reached the pool, the young lady was in the water, and it didnt appear as though she had anything on and Mike had a towel wrapped around him. Hey Unc. Mike called as I opened the pool area gate, He asked if I wanted a beer and I followed him into the kitchen. Once inside he turned to me and asked if I had enjoyed the show.

He admitted that he had seen me at the corner of the building, but didnt want to stop.

I high fived him and said it was pretty good.

He wanted to know if I was going to tell his parents about catching him banging a chick on the diving board, and trying to be the cool Uncle, I said no, but I advised him to keep a hood on the little guy so there are no surprises. Mike told me that I was pretty cool for an old guy, and that Polly had an older sister that might be into a little pool fun too, would I be interested.

I told him to check it out and let me know. I told him to get back to his friend, and I went out the front door so as not to interfere anymore. I really hoped there would be a pool party later.
