Part of me felt guilty, but not the part between my legs, because while I watched what was going on over at my next door neighbor's pool, my cock was as hard as a rock. Peeking through the blinds toward next door often proved to be an interesting sight, especially when one of the two residents was away.
You see Dave Madden and his wife Marci had a rather open-minded view of marriage, and I suspect that they knew that their spouses were not faithful. It wasn't like they were flaunting their promiscuity, and I suspect that nobody outside of me knew how they were. The only reason I knew was because we have a bedroom that looks right down on their pool and deck.
From that vantage point I've seen Marci, a plump but curvy redhead in her mid 40's, cavorting with many guys, sucking and even fucking away by their pool. Marci wasn't particular, since I'd seen guys of all shapes and hues over there. The only qualification seemed to be that they be young. Marci liked them to be barely legal.
In that respect she had something in common with her husband because he likes them young too. Young males. I was a bit shocked that first time when I saw him going down on a guy, since he seemed to be someone I had pegged as straight, but he had shown over the years that he was very open-minded, even though he had far fewer guests than his wife did.
That was okay with me, because like Dave, I've been living a kind of double life myself. It is possible to have a great wife with a wonderful life yet still yearn for the taste of a cock in your mouth. Not easy, but possible.
So I lived somewhat vicariously through my neighbor, and when I would stop home during the day for some reason, I would invariably peek over to see if Dave was entertaining someone, and he was today.
Dave was on his knees a couple of feet from his in-ground pool, wearing a bathing suit that had slipped down to expose some of his ass crack. At 50, Dave wasn't as trim as he used to be, with his 5'8" frame packing on about 20 pounds too much, and he had more hair on his back than he did on his head, but he wasn't all that bad looking in a Paul Giamatti way.
Dave was on his knees in front of a young fellow who was in very good shape, without an extra ounce on his 6' frame, and the skateboarding kid had his swim trucks down around his ankles while Dave sucked his cock.
The kid didn't look 18, but he was, and as I matter of fact had just graduated from high school last month and was going off to college in the fall. He likes to skateboard and is a computer whiz, and while I know he had had several girlfriends I had suspected that he might be bi-sexual. Seeing him with his cock down the throat of Dave Madden only confirmed my suspicions.
How do I know all this about this kid? That's simple. He's my son.
You might find this odd, that a father would stand there and not do something when he saw his son being fellated by his next door neighbor, but it was clear that what was going on was completely consensual. My son Eric is 18 and is a responsible guy, especially for his age, so I was alright with this.
As for Dave, good for him too. If I could have some young dude like Eric in front of me at my age, I'd be gobbling his tool just like Dave was down there.
The only thing that had shocked me, to be honest, was seeing Eric with an erection. My view had been blocked by Dave's head originally, but when Eric stepped back to get his trunks off of his ankles, I saw his stiff manhood waving around for a few seconds before Dave swooped back down on it.
"Where did Eric get that from?" I wondered aloud, since it certainly wasn't a physical trait he got from me, because my dick is very average at best, and if I had to guess from that brief glance, Eric's cock had to be at least 8" long.
My neighbor Dave knew what to do with it though, because he was taking all of it down his throat while his hands grabbed my kid's ass to keep him close, and he kept at it until Eric pulled him off of it.
They were talking about something, and for a minute I feared that they would be going inside, but Dave was only going to get something from the patio table.
I chuckled when I saw Dave waddling around with his boner bouncing in front of him. There aren't many guys that make me look well hung, but Dave was one of them, and when he walked over to my son it looked like Eric's cock was twice as long.
Dave handed my son a couple of things, one of them a tube of what seemed to be lube. The other thing was a condom, and as Dave went over to the chaise lounge and knelt down with his round butt high in the air, my son slipped on the condom, rolling the sheath down his long slender prong before going over to Dave.
I suspect this wasn't the first time they had done this, since they had the logistics down cold, and after Eric had greased Dave's anus he bent his knees and brought his manhood to Dave's orifice. I couldn't see the penetration but had a clear view of my neighbor's face, so I could read by his facial contortions when my son's cock entered him and slowly impaled him to the hilt.
Eric started slowly, moving his cock in and out a few times slowly before settling into a steady rhythm. My son was clearly in control, his hands holding Dave's fleshy hips as his tempo increased, and Dave was making those crazy faces we all make during sex while he held onto the chair cushions for support.
