"Could you make Jake bigger for me?"
"You want him bigger? Isn't he already big enough?" Ty wondered.
"Trust me, he's big. But I want to feel him bloat up around me. So only grow him when I give the word."
Feeling a bit enslaved himself, Ty agreed to Johnny's request. He established a mental link so that Johnny would only need to speak for Ty to hear his requests.
Johnny approached his musclebound slave, who had returned to lifting weights in the garage. Sweat glistened off his pumped muscles as he grunted loudly, lifting the weight bar quicker and quicker with each rep.
Johnny ran his hand across Jake's muscles once again, feeling them tense and relax with each powerful rep.
"Looks like you're going to get even bigger for me today, slave. We're going to make you into such a monster, nobody will ever dare to bully me again."
Jake grinned as he completed his last rep. The thought of more power excited him as his previously flaccid cock rose to attention. He set down the weights and stood to his full height. Towering over his master, Jake followed Johnny to the open space on the floor in the garage.
"Lay down." Johnny said.
The gargantuan slave laid on his backside, his massive pectorals stuck high into the air like a shelf. His cock arced nicely, bristling against his washboard abs. Johnny climbed on top of Jake's pecs, feeling their warmth and firmness as he groped them in anticipation. He stared over the pecs into Jake's eyes: the slave looked back at him in true lust as they waited for Ty's power to kick in.
"I'm ready Ty. Grow my muscle slave for me."
Right on queue, Johnny felt a tingling below him.
Suddenly Jake's body became very hot. Not searing, but a tepid warm. Johnny realised that he was being lifted higher off the ground as Jake's already huge body swelled even bigger. His slave's biceps grew to the size of watermelons, his gigantic pecs expanded, creating a deep chasm that Johnny almost fell into. Jake's face became more chiseled, more manly. A small amount of stubble grew around his jawline, giving him a slight 'pencil beard'. Whilst Johnny found that incredibly sexy, that fantasy was short-lived, as more of the blonde hair grew around his cheeks, giving his slave a full dusty blonde beard. As handsome as his face was, it was becoming obscured behind the masses that were his mountainous pecs, crowned with fattening nipples the size of Johnny's fists.
Jake threw his head back and moaned as his body continued to swell ever larger. He had reached the 500lb mark by this point, showing no signs of slowing down. Johnny's legs raised up as his muscle slave's stomach distended to form a huge muscle gut. he moved his feet through the crevices of each of the abs, feeling them rise like baker's loaves in an oven. He turned to sucking on the engorging brown nipples, which had developed a dusting of blonde hair around the areoles. He licked up the salty taste of his giant's sweat, listening blissfully to the guttural moans coming from behind the mountainous pecs.
"Awwww FUUUUUUCCKKKK ... yaaaaahhhhhhhh" the giant moaned as he felt his master's tongue slide around his tender nips.
"You like that, big guy?" said Johnny through the licking. His slave's answer only took the form of intangible moans.
"I guess that's a yes" he thought.
As he was paying lip service to his slave's flesh, Johnny felt something graze his naked butt. It seemed small at first, but as the seconds went by and the growth continued, the small master felt it grow too. He identified it as the beast's penis, which had grown so big by this time that it had become as big as Johnny himself. Still it continued to swell, looming over the boy as a titan in its own right. A big glob of glistening pre cum formed at the tip of the monstrous dick. Shoulders widened and thighs bloated to enormous proportions, and the slave started to buck intermittently from the pleasure, his growing form taking up what little free space was left in the garage. The glob of pre cum dropped from its perch, splashing all over Johnny and covering him in sticky man fluid.
Another sphere of the sticky fluid formed at the tip of Jake's fat cock. Before it could drop again Johnny asked Ty to stop Jake's growth.
The sticky pre cum dangled all the way down to the little master's face, where he turned his head slightly to avoid it brushing up against him.
He closed his eyes and hoped that it would not drop.
Nothing happened.
Johnny opened his eyes. In front of him was an orb of clear pre that was roughly the size of his face. It was held suspended in mid air by the biggest, fattest shaft of flesh that he had ever seen. The pink head too glistened under the pale glow of the indoor light, (which nearly touched the shaft itself!). He carefully moved around the orb and took a look at his handiwork.
Roughly 7 feet in the air, Johnny suddenly had an irrational fear of heights as he peered down to the ground below. Most of it was taken up by his massive slave, whose growth had knocked the weights that had previously been a challenge for him to one side. His upper arms were enormous: there was no longer any type of melon that could describe the size of those beasts, which had to be roughly 56" around. Thighs that were definitely bigger than two adult men's waists were the example of masculinity.
"(Men that belonged in the 'Sumo Face-offs')" Johnny thought.
A set of baritone rumbles emitting from the chest caused Johnny to turn his head. He crawled over the expansive furry pecs, by which the nipples had swelled to the size of his head, to see the face of his handsome bearded slave. His eyes were still shut in pure ecstasy, his short blonde spiky hair and strong brow ridge shining with traces of sweat.
Strangely enough, his head was only slightly enlarged in comparison to the rest of his body, which had in conversely swelled to massive proportions. Johnny gingerly made his way over the shelf of the pace and straddled the bull neck of his slave, cupping his head with his hands. He lightly twiddled some of his newly grown beard hair with his fingers, causing the beast to awaken from his erotic trance.
"MASTER ..." He rumbled. The tone resounded through Johnny.
"Welcome back" Johnny said.
