Switching places, Noah gets on the chair, leans forward, and I undo his pants, pulling them down to give him a rimming. I got right in his crack, licking and tonguing his sweet hole, then moved down to lick from his cock up to his hole. I continued the process until I was ready to fuck. I slowly entered, pushing, inch by inch, until I was hitting a dead end, his second hole, nudging it. He knew what was coming, but resisting, he knows every time we fuck, I will win this battle. Then he let go, and I pushed through, telling him “there you go”. We kept going until I wanted him to ride me and I sat down in the chair again. Noah backed up to me, spread his legs outside mine, sinking down on my cock, resuming our fuck until he decided to put a foot on each thigh as we resumed. But I wanted this time to be special, wanting to kiss him, getting Noah to turn around facing me. We kissed, continuing our lovemaking. As the intensity grew, I had to slow him down to not cum too quickly.

But that didn't last as we both got into our rise in man-on-man sexual tension until my cock swelled even larger, Noah moaned even louder when it expanded knowing the natural signal of a male going into a rut, and then I shot a nice load of warm creamy cum inside his ass. Oh, how sweet it is! I love my son and hopefully this will be a birthday to remember, but until the next one, we will find plenty of reasons to celebrate, such as Ground Hog Day, Arbor Day, National Doughnut Day.
