Tony stood up... and grew up and up and up! Soon he was as tall as Ben, then taller... in a few minutes he was head and shoulders taller than Ben! Ben looked at Tony in awe! Ben's attention was drawn to Tony's sweatpants and he saw that Tony's cock had grown in proportion with his height increase!!
And he couldn't help but have his jaw drop at the sight of the incredibly big balls rapidly growing.. like water balloons filled from a faucet he saw them inflate and swell and grow larger and larger as the fabric in the crotch of the sweat pants stretched. A sheen of sweat covered Tony and Ben noticed the smooth skin of his abs starting to distend with developing cords of muscle. Tony's t shirt was now hanging down to a bit above his belly button... where a few minutes before it had been easily tucked into his sweatpants.
Tony looked unsteady and Ben grabbed him and Tony leaned on Ben to support his weight... which Ben held easily at first but then Tony became more and more of a burden as his muscles grew!!!
Ben couldn't believe how turned on he was as he felt Tony's chest swelling against his cheek and Tony's long arm around Ben's neck grew thicker and the bicep bulged up and pressed harder and harder against Ben as it grew!!!!
Dark hair grew up in a tangled forest from Tony's groin and up his abs and Ben could feel the hair on Tony's forearms growing and thickening and rubbing against his face as Tony grew!
Ben's head was forced downward by the growing weight of Tony's rapidly bulking up body... right to the table and the packets!
There were a bunch strewn there. For some reason Ben felt panicked... he started to read the packets on the table...
"Big Feet" "Short Stuff" Strength increaser... Ben grabbed that one... it read "Strength increaser- makes one strong and impervious to most pain and produces very dense muscle"
Ben tore the packet with his free hand and swallowed the powder. He heard Tony's shirt and pants tearing as his muscles swelled even larger than the stretched fabric could hold!
"dance boy" "String Bean" "Tall and Rangy" "Skinny and hung"
"Multiple orgasms" Ben grabbed that one... "increases sexual pleasure, frequency of possible ejaculations, increases duration and intensity of orgasms... side effects may include increased ejaculate volume and heavy precum flow.
Ben tore that one with his teeth and swallowed it. Tony was doing better... he pushed away from Ben... stood up... stood up and up!!!!
