Max nudged Chad out as Brad pulled. At 60lbs, a third of his human weight, Chad was no match for the 150 lb animal, and his two hundred pound older brother. He was quickly shepherded by Max into the mesh metal enclosure that Brad had built in the cargo hold of his SUV. Max followed Chad in, and forced him down on the rubberized floor bed. Then Max lay on top of him. Chad struggled but Max's mass held him down. Chad barked angrily, and Max gently but firmly swallowed Chad's muzzle between his powerful jaws. Chad could feel the sharp teeth of the mastiff through his fur, but they didn't break the skin.
"Good boy, Max! Thanks for shutting up Chatty Chad, he always makes too much noise. A few weeks of obedience training should make him a quiet pup. Cannot wait to give him a proper poodle cut. And I know Max that you cannot wait to pop Chad's cherry when we get home."
Max's slimy penis slid out of its sheath and pressed hard against Chad's back. Chad whined softly. Max shifted, burying his cock deeper into Chad's backside. At least Chad's rosebud was still virgin, but any hope that Brad would spare Chad from that part of his training was dashed.
