My wife has been out of town for almost 3 weeks. Me being the lazy older (57) guy that I am haven't mowed the yard since before she left. Ran into my neighbor up the street at the grocery store and he told me his 19 yo sone was looking for any odd jobs to do to make some money before going off to college. I said to send him down this weekend, I need my yard mowed. Everyone knows his son is gay, but no one cares. Totally fortgetting about him coming Saturday afternoon, I was flowting around my pool having some beers and the kid shows up. It was hot that day, but little did I know how HOT it would get. So he proceeds to mow the yard and of course got all sweaty. Before he started the trimming, he asked if he could jump in the pool to cool off. Sure, help yourself I told him, as now I'm several beers into a lazy afternoon. He tells me he doesn't have a bathing suit but if it's okay, he'll just skinny dip then finish the lawn. No big deal, we're both men.

     So he removes his shirt, and turns to slide his shorts and underwear down, and without realizing it, I'm staring at his shaved ass. When he turns around and starts walking down the steps into the pool, I can't help but look at his shaved cock dangling as he slips into the water. He swims up to me on my floatie and says "Mr. Rob, you must have liked what you saw". A little puzzled, I said what do you mean. He replies "you have a boner in your suit". A little embarrassed, I looked down, it wasn't a boner, it was a raging rock hard, hardon! Without a word, he grabs my cock through my swim suit and starts to jerk it, I slid my suit down a little and as my cock sprang out, I slowly guided his head to it. His mouth felt so warm as he engulfed my cock. I looked down into the water and could see his young thin but long cock sticking straight up. He too was horny and hard. I slid off floatie into the water wiaste high, and grabbed his cock as I kissed him deep and hard with my tongue. I put our cocks together and jerked them under the water together. Both of us were moaning in each other's mouths. I reached and grabbed his bare shaven ass and pulled him to me, meshing our cocks into our pelvis's and spread his cheeks with a finger while slowly sliding another into his ass. He moaned loudly and said Yes, please Mr. Rob, yesssss. Now with my cock throbbing incredibly, I turned him around and pushed him to the side of the pool where he grabbed the edge, offering his tight teen ass to me. Obliged from this point on and with no chance of turning back, I slowly slid my cock between his ass cheeks till the head of my dick was at heaven's door. He winced a little as I puched forward, at the same time grabbing his hips and pulling him back.He also pushed back onme, I knew at this point I was going all in. With a thrust I pushed into him, he let out a gulp, and then started moaning yes, yes, more Mr. Rob. I continued to fuck him as fast as the water would let me back and forth into his tight love hole. All the while I reached around and grabbed that young sprung cock of his jerkiing it with each thrust. I heard him say "your gonna make me cum, Sir" and that's all it took, I pushed all the way into him as I could go and my nuts began pumping his ass full of my love load, and then I felt his cock pulsating in my hand as he too came in my pool. 

     We both just stayed there a minute exhausted and satisfied from our romp in the pool, then he slid off my cock as it went flacid still in his ass. he swam away and said he had to finish the yard before dinner. I watched him exit the pool and towel off, his tight twink ass facing me as he bent over to get his clothes. I was a little shy for what happened, but he said it was a great experience for him. I paid him a little extra that day, and he offered to help me out anytime. I also invited him to CUM to my pool, anytime. 

This was just a fantasy of mine, but my cock is so fucking hard righ now, and pre cum dripping all over my fingers, I need ot finish getting off.
