"Yes, sir!" Tim said, whipping his towel off but facing front to expose his own hard foot of meat for Scott's inspection.
Scott blinked, falling out of character. "Tim," he said slowly, "Tim, you are huge!" He put both his big, strong hands on Tim's rod, feeling it's firmness. Then one hand slipped lower to feel the large rocks that hung in Tim's sac. Satisfied that everything felt perfectly healthy and normal, Scott looked up from Tim's equipment back to Tim's face. "How?" he said.
"Suck me off, and then I'll explain," Tim said with a smile, pleased with the sudden role reversal. He didn't have to ask twice. Scott was on his knees in a second, enthusiastically stuffing as much of Tim's cock as he could down his hungry throat.
Scott was a little clumsy with Tim's blowjob, but what he lacked in experience was made up for in enthusiasm. Tim realized that Scott probably always wanted to find some cocks big enough to be worthy of him, but they were doubtless in short supply. Was this sudden change of heart on Scott's part temporary, or would things be different now that Tim was the Big Dick around the place?
Tim ran his fingers through the thick hair on Scott's head, and then down to feel his strong shoulder muscles as the bigger man bobbed his head up and down. Scott would make a great pet, Tim thought, if he was just smaller. Some combination of sex toy, teddy bear, and munchkin all rolled up into one.
Tim's orgasm was building as he slipped his hands through Scott's shirt collar to feel the lightly-furred upper back underneat. Scott usually wore shirts that were so tight they looked painted on, undoubtedly to show off his great body underneath. But now there seemed to be a little extra fabric around the collar. Tim felt his balls tightening up and he wondered if there was something in that chest that could shrink Scott after all.
Tim put both his hands on Scott's head and grabbed it firmly as he closed his eyes and started to cum. He wanted Scott to shrink. Oh, yeah. Shrink. He felt the wads accelerating down his dick just like last time. It felt incredible. Fuck yeah, shrink! He felt Scott's head deflating in his grasp like a balloon that was having air let out. Was it his imagination? He couldn't be sure, but Scott tried to pull away and Tim held his partner in place until the orgasm was spent.
Tim stumbled back against the wall, his knees shaky from the intensity of his ejaculation. He opened his eyes and looked down at his hairy friend.
