Chapter 1 -- Big Boy Underwear I couldn’t believe my eyes when this came in. The guy who sent this to me has been telling me about the things he has to do differently now that his stepson is growing up. For instance, he loves seeing the boy’s body develop and change. But this means his stepson needs to start dressing more his age. His stepdad loves seeing him in his cute, little boy underwear, but he knows his stepson has outgrown his usual superhero underoos. One day he gave his young boy a well-cut brief to showcase his cute little butt and his penis. He couldn’t believe how hot it was. The boy was reluctant to change and show off in front of his old man, but the handsome stepdaddy was just so proud of his growing boy. And as you can see in the video, he’s growing in more ways than one! He’s lucky to have a stepdad who teaches him the value of well-made underwear. To make the boy feel comfortable, the older man pulls down his pants too and shows his stepson what it’ll look like when he gets older. The boy can’t take his eyes of his stepdad’s cock, and I can’t blame him. The man’s tool is so hot. Sure enough, the sweet, sexy stepdaddy can’t control himself and gets his mouth on his boy’s tight, pink hole. He kisses him passionately and you can see his stepson practically quiver with each lick.
