Dr. Wolf lifts up Caleb's leg as he leans against the table. Even with its standard height, Caleb has to stretch to get himself onto its wooden surface. As he holds himself in place, Wolf brings his slick shaft up to his hole, resting it in place gently. Wolf gives it a slight push forward, feeling the pressure of Caleb's body surround the head of his manhood. The boy lets out a soft moan, feeling his skin stretch over the bulbous shaft, waiting for the familiar pop of his hole yielding and opening... Caleb felt the head of Wolf's cock inside him, occupying an inch inside his body, breaking the seal, and making them one. He let out a gasp, feeling how wide his hole stretched in order to take it. Wolf went slow at first, moving in ever so delicately as not to hurt his young bottom boy, but he knew he could only hold off so long. He wanted to feel every bit of his size engulfed in the boy's cavity, pulling out only when he'd left his seed in its place!
