These young boys grow up so fast. I hardly noticed how much my stepson Josh was growing until he came into the living room wearing a shirt that he obviously outgrew. It blew my mind so much that I had to measure him from head to toe. I grabbed the tape measure and started working it all over his growing body. I then had him take off his clothes and didn't realize how much his new body turned me on, especially his hard cock. I've never touched him before, but I couldn't help but put my mouth on his hard cock. That lead to my boy kissing daddy and then showing me how much he has grown. He sucked my dick so well that I had to let him ride my cock. It clearly wasn't his first time with a cock in his ass, but it felt as tight as a virgin. I fucked him until he came on himself, and then I mixed my load with his. I can't wait till we do it again.
