Dad Breeds Twink Son Zac on His Birthday - Bareback Spanking & Rimming

Zac's birthday had finally arrived, and any reason to fuck my boy was a good one in my book. Of course, that wasn't the only gift waiting for him. I'd give my pride and joy anything his heart desired if it were within my power. But I couldn't pass up the chance to give him a proper birthday spanking either. Bare-assed, naturally. Just like the old days, except not quite. Disciplining my son used to be a father's duty. This, though, this was a dad's pure pleasure. It felt like a flashback, only now I was staring down at a grown young man's firm, round ass. An ass I'd fucked countless times before. Moments like these always reminded me that I was the one who sired Zac. I fucked him into existence with the same cum I now pump into his hole. Then I spent years raising him into the fine young man squirming across my lap. As my hand came down on him, I felt that intoxicating blend of paternal pride and dominant Daddy energy take over. My sweet boy. My tight little fuck hole. My cock, rock hard in my pants, pressing into his stomach as each smack landed and made him jolt. That first swat caught even me off guard with its force, but he barely let out a whimper, so I kept going, growing harder with every strike. Then he arched his ass up, his cheeks spread for just a heartbeat, and his hole winked right at me. I couldn't resist that invitation. I climbed onto the bed beside him, spread his legs wide, and started unwrapping his birthday present. A funny thought hit me right then. Now he understood exactly how it felt when he was little and used to buy me a box of his favorite candy every Father's Day, knowing full well he'd get to eat half of it himself.
