I had just gotten home from work and my daughter was in the den with her bff both in short shorts lounging around in the den showing off more than they probably should be, but damn, it did look good. My son was of course in the kitchen eating. It's what teen boys do and my wife was in the office finishing up whatever she does for work. I decided to head upstairs and change into something a bit more comfortable since I already had a semi-erection from the view in the den.

I had just stripped out of my shirt when I heard something fall outside. I looked out the window into our yard and didn't see anything but heard some scraping that sounded like it was coming from next door. We have a window that looks down partially into our neighbors yard so I looked to see what was going on. Tori, 16yo daughter next door was setting up a couple of loungers by their pool. She looked really nice in her cover up, all I could see were her tan legs but I figured I would watch for a few minutes in hopes to see more.

A guy came into view about that time and gave her a hug and grabbed a handful of her ass. She pulled away and went inside while he stripped down to just his swimsuit. She appeared with a couple of sodas and glasses of ice and then pulled off her cover up. It was definitely worth the wait; it looked like good c-cup titties to me and there wasn't much to the bikini bottoms at all.

I went over and looked down to the first floor to see if everyone was still busy and went back in to my room, locking the door as I did. I went ahead and stripped down the rest of the way and went back to the window with my 6.5" cock hardening. I fixed the slat on the blind so it would stay up and saw they were making out. My cock sprang to full attention at that point.

The guy pushed her bikini top up exposing her perky titties, they weren't huge, but they were perfect from my vantage point. I wasn't sure I would be able to look her dad in the face after seeing them. He went to work on her, sucking and licking her titties. She seemed to really enjoy the attention and went ahead and pulled the top off completely. Her right hand slid down his swim trunks and I'm guessing caressed his cock as he rolled to his side giving her a bit more access.

He broke the fun and stood up and took off his swim trunks. It amazes me how a hard a young man's cock is compared to a middle aged guy like me. Next she started licking and sucking his cock, not sure how big he was but she had no problem with him. All the while I was sliding my hand up and down my cock spreading my precum on my head and shaft. He once again broke the action and pulled at her bikini bottoms and slid them down her legs. I'm not sure if all girls her age shave or wax but from my vantage point, I saw no hair. He promptly went down on her licking her pussy and her head went back like he knew what he was doing. Pretty sure this wasn't their first encounter. When it was pretty obvious she had had an orgasm, he climbed up between her legs and slid his cock into her wet pussy. He didn't last long and neither did I.

I shot my load into my hand and had just made it into the bathroom when I heard my wife knock on the bedroom door. I told her just a second and quickly washed my hands and grabbed my underwear. She asked why the door was locked and I said I guess I accidentally locked it when I came in. As she went into the bathroom, I looked up and saw the blind still out of place and slipped over to fix it before she saw it. Of course I kept a better eye on our neighbors backyard to make everything was okay over their until she and her younger sister moved out.
