Evan’s grin widened as he loomed over Mark, his towering frame casting a shadow that seemed to swallow his brother whole. The air in the room felt heavy, charged with the weight of Evan’s dominance and the unspoken promise of what was to come. Mark lay there, trembling, his body still tingling from the overwhelming sensation of Evan’s massive cock pressing down on him. Was he hard again? But Evan wasn’t done. Not even close.
“You know, Mark,” Evan began, his voice dripping with dark amusement, “I’ve been thinking. You’re already so small, so weak compared to me. But what if we took it a step further? What if I could change you… with just a touch?”
Mark’s eyes widened, a mix of fear and curiosity flickering in them. “W-what do you mean, Evan?”
Evan didn’t answer. Instead, he turned to the Chronivac, his massive hands moving with precision as he input a new set of changes. “Let’s give myself a little upgrade,” he muttered, his voice low and commanding. “The power to reshape you… physically, mentally, however I want. All I need to do is touch you.”
He pressed the button, and a surge of energy coursed through Evan’s body. His eyes glowed with a newfound intensity. He flexed his fingers, feeling the raw power coursing through them, and turned back to Mark with a predatory grin.
“Let’s test it out,” Evan said, his voice a deep, resonant growl. He reached out, his massive hand engulfing Mark’s bicep. “First, your muscles. You don’t need them.”
Mark gasped as a searing sensation shot through his arm. He watched in horror as his muscles seemed to melt away, his arm becoming thin and delicate. The sensation was agonizing, like his very essence was being ripped from him. He cried out, his voice high-pitched and girly, but Evan only chuckled.
“Oh, don’t be such a baby,” Evan said, his tone mocking. “This is just the beginning.”
He moved his hand to Mark’s chest, his fingers dancing across his brother’s pecs. Another wave of pain washed over Mark as his chest flattened, his muscles disappearing until he was left with a slender, almost feminine frame. Evan’s touch was electric, sending jolts of energy through Mark’s body, but Evan himself seemed to revel in the experience. His cock twitched, growing even larger as he absorbed Mark’s strength, his own body becoming more powerful with every moment they connected physically.
“Next, your height,” Evan said, his voice filled with dark amusement. He placed his hand on Mark’s head, and Mark yelped as he felt his body shrink. His legs grew shorter, his torso compacting, until he was a full 3 feet shorter than Evan. The difference was staggering, and Mark felt a wave of humiliation wash over him as he looked up at his brother’s towering form. Had he grown again? He now looked superhuman, like a titan of mythological descent.
“Now, your voice,” Evan continued, his tone almost clinical. He grabbed Mark by the throat, his grip firm but not enough to choke him. Mark gasped as his vocal cords seemed to twist and shift, his voice becoming high-pitched and girly. The feeling was strange, like his throat was being ripped apart from the inside, but Evan only laughed, feeling his own voice deepen yet again.
“Perfect,” Evan said, his eyes gleaming with satisfaction. “Now, let’s address that little cock of yours.”
Mark’s hands instinctively flew to his crotch, but Evan was faster. He reached down, his massive hand engulfing Mark’s cock, and Mark screamed as a an intense numbing sensation shot through him. His cock began to shrink, dwindling down to a mere three inches, soft and insignificant. At the same time, Evan’s own cock grew even larger, thickening and lengthening until it was a monstrous two feet long, the veins pulsing with raw power.
Evan, satisfied with the changes, beckoned the petite and naked femboy over to him. Mark's head was almost at eye level with Evan's cock, which was now pulsing with vitality and leaking precum. “Now, for the finishing touches.” He picked Mark up and forced him on his lap as he sat, allowing his cock to ride against Mark's thighs.
“And just to make sure you don’t get any ideas,” Evan said, his voice dripping with mockery, “let’s lock that little thing up.” Another touch and a small, pink chastity cage materialized around Mark’s shrunken cock, the metal cold against his skin. Evan slapped his massive meat rod against the plastic frame, laughing at the sound it made and the sheer size difference between the two cocks.
"Every slut needs a wardrobe, no?" He stood Mark back up and began using his magic hands again. Mark’s clothes vanished, replaced by a ridiculously slutty outfit: a crop top that barely covered his chest when Evan groped his slightly puffy nipples, a black miniskirt that barely covered his hanging chastity cage, and nylon thigh-high stockings with garters. The fabric was tight and revealing, and Mark felt a fresh wave of humiliation as he looked down at himself. A touch of Mark's feet made 6 inch pumps that screamed "Fuck me!" appear. Mark had a feeling he would be getting used to wearing those.
“And let’s add some… decorations,” Evan said, his grin turning wicked.
Mark gasped as piercings appeared on his body: a ring through his nipple, a stud in his navel, and a delicate chain connecting the two. His ears were adorned with sparkling studs, and a small, heart-shaped tattoo appeared on his hip, the words “Daddy’s Toy” written in cursive beneath it.
“There,” Evan said, stepping back to admire his handiwork. “Now you’re perfect.”
Mark looked up at his brother, his eyes wide and pleading. “E-Evan, please… this is too much…”
Evan’s expression softened for a moment, but then his smirk returned, darker than ever. “Oh, Mark. You don’t get to complain. You wanted this. You wanted to be reminded of how inferior you are. And now… you’re mine. My perfect little femboy sex toy."
He reached down, his massive hand engulfing Mark’s slender waist as he lifted him effortlessly into the air. Mark squirmed, his girly voice letting out a high-pitched squeak, but Evan only chuckled.
“Don’t worry, bro,” Evan said, his voice a low, sultry growl. “I’ll take good care of you. After all, you exist for one purpose now: to serve me.”
And with that, Evan carried Mark to the bed, his massive frame looming over his brother’s smaller, feminized form. Mark’s heart raced, his mind a whirlwind of fear, humiliation, and something else he couldn’t quite name. But as Evan’s hands began to explore his body, Mark knew one thing for certain: he was completely and utterly at his brother’s mercy.
