"Fuck" was all Branden could say as he admired the new twice as beefy version of Tony from the couch.
As he laid down looking from below Tony seemed to be even more gigantic-looking. Now at a whopping 11 feet tall, Tony towered over Branden like a newborn Muscle Adonis.
Tony's cock was bubbling like a fountain with thick, slimy strands of cum falling down around it in all directions. His testicles hanging like giant over ripe fruit- they had swollen to an insane size.
"What is happening to me Branden?" asked Tony as he started to pose for both himself and Branden to see how massive he'd truly become.
"I don't know man... It could be because you were already bigger in size before, the formula just multiplied your mass exponentially or something... man we have to get you to my stepdad, he'll work this out for us"
"Are you kidding?! We can't just go outside trying to find your stepdad looking like... THIS!" cried Tony, as he flexed a hurculean bicep to make his point, making endless snaking veins of all sizes pop up on the surface of the skin.
"Besides... I think I like this!" said Tony in a cocky tone and with an evil smirk.
Branden wanted to be rational and work out was happening to them. But the sexual urges were so overwhelming. The feeling of such power.. so hot.
Branden looked up at Tony again.
"Hey Tony.. do you think you could..." he began.
