Colin's moans grew louder as his almost painfully erect cock was devoured by his little brother, still under the effects of The Maker's mind control. "Ooooooh! Yeah! C'mon Sam, lick my big mancock! Yes! YES! YES!!!"
Colins hips began thrusting into Sam's mouth of their own accord. He grabbed the back of his little brother's head with his massive hands, pushing the thin face forwards, forcing him to devour more of Colin's massive endowment.
Then, with an animal roar of passion, Colin came. His cum exploded into Sam's mouth, and the little boy greedily gulped the salty liquid down. He could swallow faster than Colin apparently could, for none of his brother's potent manjuice escaped him.

Colin smiled at his mind-blanked little brother. He had just stepped out of the shower after cleaning up, enjoying the feel of his new body while cleaning off the copious amounts of sweat he had produced during his blowjob. "Well, little bro, since you're so good at attending to my whims, you're now gonna do that full-time. Too bad your original mind won't be around to enjoy the new body I'm gonna give ya to do it in."
With that, Colin made another trigger gesture, and the beautific, lustful smile on Sam's face grew even wider as the last remnants of his old personality were swept away. He was now nothing more than a sex toy for Colin's personal use.
"Oh, please master, improve my body so that I may better serve to your needs. I ache to prove myself to you," Sam said, adding as an afterthought, "In as many positions as possible."
Colin grinned again and said, beckoning, "Then come over here, Sam. I've got something to show you."
As Sam reached Colin, the older boy grabbed his brother by the shoulders, facing him away from Colin. "Now bend over. I'm gonna take that fine virgin ass of yours. When I cum, you'll change."
