Kevin lays in wait, curled up in his snake form behind the benches - "damn" Kevin thought "Joel really likes Carlos, I wonder what it would feel like to have Joel's love"
Just then Chris a build Californian surfer came through the door and sat on the bench. Kevin checked him out in the mirror opposite; his bronzed skin glowed, thick athletic legs, up to a huge bulge in his shorts. His narrow waist grew into a 46" chest with huge square pecs. He stretched clearly showing his thick biceps.
He leaned forward resting his arms on his knees, Kevin licked his lips seeing the spread of his huge lats - he knew this was the perfect start for Joel's collection.
Kevin increased his size, reaching over the back of the benches Kevin grabbed the guy by the throat; wrapping his snake like body around this neck a couple of times.
The big guy struggled, knocking over a chair and a table as Kevin dragged him backwards over the back of the bench - Kevin tightened his grip and the guy fell unconscious.
Using the skills he'd learnt from Joel, Kevin pushed into the mouth of the guy; almost 6' of snake forced its way into the surfers body, with a flick of a tail the last of Kevin slid into his body and down his throat.
The surfers huge body twitched and groaned as Kevin took control, getting up Kevin walked over to the mirror checking out his new body "fuck" was all he could say.
Kevin looked into his new face; deep blue eyes, strong jaw and a very handsome face, shoulder length sun bleached hair topped his head. Kevin raised a hand to push his hair back; and gulped looking at the size of his expanding bicep. Kevin flashed a smile at his reflection, the effect was amazing.
All this time Joel was watching - although Kevin didn't know it Joel was able to see through Kevin's eyes, and he even knew what Kevin was thinking.
