It was Zac’s birthday. Any excuse to fuck my boy is a good excuse. Of course, that wasn’t the only present he got. I would get my pride and joy anything he wanted, if I could. I couldn’t resist giving him a birthday spanking, as well. Bare-assed, of course. Just like old times, except not really. Disciplining my son was a father’s duty. This is a dad’s pleasure. It was like a blast from the past, but I was looking down at a young man’s firm round ass. One that I’ve fucked on many occasions. It was one of those moments when I’m reminded that I sired Zac. Fucked him into his mother with the same cum I fuck into his hole now. Then I spent years raising him up to be a fine young man. As I started to spank him, I was overcome with a mix of paternalism and dominant Daddy. My sweet boy. My tight fuck hole. My dick, hard as a steel pole in my pants, poking into his belly as I brought my hand down hard, making him squirm. I almost surprised myself with the force of that first swat, but he barely whimpered, so I kept going, getting more turned on with every smack. He raised his ass, his cheeks parted for just a second, and his hole winked at me. I couldn’t resist it. As I crawled up on the bed beside him, spread his legs, and started to give him his birthday present, a funny thought occurred to me. Now he knows what it was like when he was younger and always bought me a box of his favorite candy for Father’s Day, because he knew he would get to eat half of it.
