Dave's lust was strong but his rational brain overrode his thoughts for the moment. "Look at what's become of you" he thought, looking down at his now much more manly body. "Stop acting like an animal and get out of here, maybe you can find a way to regain control."
He really wanted to keep exploring and toying with his own bod but he knew that was just the hormones raging and thinking for him. He had to get out, somehow get home, to the safety and comfort of his own bedroom where he could think this through.
If he could just get the door open... Dave fiddled with the handle but to no avail. Maybe if he just bashed it down... wasn't this bigger body good for something? He started pounding on it with his fist, which hurt, but he could see the cheap plywood cover of the door start to crunch right through.
