Zac asked me to help him pick out a pair of pants. My boy is going on his first date. He still doesn’t have a girlfriend, yet. His best friend, Mike, met some girl at the mall. Since they didn’t even go to the same high school, her parents would only let them go out if they double dated. Mike recruited Zac to go, and the girl got a friend of hers to make four. I think he is probably even more nervous “going out” with a girl he’s never met than if he was actually going on a real date. That’s not something we’ve ever talked about. We have our relationship, but I don’t know what his broader attractions are. I know he will meet somebody some day, and I’ll step back out of the way. Boys grow into men, and they go out in the world to live their own lives. I won't lie, though, if Zac turns out to be Daddy-sexual I’ll be the happiest dad on the planet. Today, we were supposed to be picking out pants for his date, and I’m afraid I was no help at all. The only thing I wanted to see my boy wearing was his birthday suit. None of his pants looked good when he zipped up the fly and hid that plump bulge in his white jockey shorts, and I knew I could get it back again by shaking my head. Finally, I couldn’t stand it anymore. I had to reach out for a feel, and Zac moved closer. I could see it growing larger under my touch.Of course, that’s not what I really wanted. I stood up and Zac took my place on the bed, on all fours. I stroked the round peach of his ass through the white cotton stretched across his firm mounds. I carefully pulled them down to reveal his hole in the cleft. My hole. I took his cherry, and I’m still pretty certain nobody other than me has ever fucked my boy.Just the sight of it sent a thrill of pleasure through my body. My cock throbbed, so hard that it hurt. I almost groaned out loud, as I bent down, extending my tongue, and gave it a lick. So good! I pressed my face in, working my tongue inside of him. I could eat Zac’s ass all day. Or at least until my tongue got so tired that I couldn’t lick anymore. The way Zac was whimpering and moaning, I don't think he would mind if I did.My cock needed his ass badly, though. Zac needed to suck it first. Get it nice and wet, so it would slide in easily. He sat up, and I shucked my pants down, letting it out. He always looks at it like he’s never seen it before, or maybe he just still can’t believe that it will fit inside of him, even as often as I’ve fucked him. I tell him that his hole is the perfect size for the cock that made it.After he sucked me, I couldn’t resist having another taste of him. But I needed to be inside my boy. I got him on his back, holding his legs up for me, with a pillow under his hips to get him to exactly the right spot. I love to watch his eyes get wide as I sink into him. His body just opened right up for me like it always does. Of course, he was gasping and whining. So sexy! I just kept going deeper. I know he would tell me to stop if he couldn’t take it.When I felt my balls resting against his soft skin, I knew it was time to fuck. Out. And back in. Feeling his guts quiver and quake around my hard dick stirring them around. Damn! It’s just the best feeling in the world, looking down at my sweet sexy boy, laying there, with his legs spread open, letting his dad have his body. His prick was almost as hard as my cock plowing into him. My good boy loves his daddy’s dick as much as I love his ass. I can’t say what feels best, fucking my boy, or breeding him. A man can only fuck so long before he has to fill his hole up, though.
