Less brains, more brawn

"Strip!" commanded Kate.

"Yes, goddess!" Jack ripped off his clothes, throwing them in a corner. When he was done, he got back on his knees and waited for more instructions.

Kate looked over her ****. "Hmm. You don't really work out, do you? Well, that's kind of useless." She tinkered with the controls on the remote as she continued. "You see, I already have a fiancé. I love him, and he loves me, so I don't need you for anything like a relationship. All I want from you is... a body!"

Kate pressed a button, and Jack's muscles started to grow. His body changed from a typical, nonathletic thin build into an olympic swimmer's physique. Then Kate pressed a few more buttons, and Jack's face started changing, becoming more chiseled. Next she adjusted his hair, lightening it a couple shades from dirty blonde to a nicer, truer blonde. He was still recognizable, but he looked like a perfect version of himself.

"Oooo, very nice," said Kate. "Except there's one more tweak that you need."

With another button press, Jack's cock grew significantly. The length increased a little, but the girth grew significantly.

"Fuck, that's perfect! Ha! Okay, now that you've got such a great body, I really don't need your mind anymore. Sooo..."

Kate found the IQ setting and slid the setting down to 50, watching the light fade from Jack's eyes. "Jack? Do you understand me?"

"Yes, goddess." His voice sounded simpler in some subtle way, but the devotion and love were still there.

"Hmm, that may have been too far. The goal is to get you to a point where you can still make me a mixed drink, but that's the most complex thing you can do. I guess we'll test this IQ setting and adjust it later if necessary." She looked over his new body again, resting her eyes on his now large cock.

"Right now, let's test some other things, first!"
