Little Butt and the Behemoth 43: Coach Rockhard

(“Clean-up in cubicle 2!,” crackles Dr. Klein’s voice over the intercom… The stern nurse stalks by, looking grumpy and carrying a large bucket and mop.)

“The blood test wasn’t bad at all,” I say. “At least, once the assistant managed to get a needle through my tough hide. It took her a couple dozen stabs, though – good thing the Behemoth's nearly impervious to pain,” I chuckle, grabbing Joey’s round butt cheek in my big hand and squeezing.

“Eek!,” he squeals, jumping a few inches off the floor. “Too bad I’m not!”

After all the talk about size-difference, little Joey’s looking way too irresistible to ignore. Man, his up-tilted ass looks like it could use a good reaming, and it’s giving me horny ideas I can't resist. Tripod’s already jerking under my clothes with impatience. I’m definitely not the only one with a huge boner in Dr. Klein’s waiting room, but I prefer privacy.
