Round Two

McKenzie looked down at the buxom goddess gripping her cock and lost all rationality. Somehow, Annie seemed more beautiful than ever. Her breasts bulged bigger, her skin glowed softer, and her eyes were filled with lascivious desire.

I shouldn't do this, McKenzie thought to herself right before taking her meaty cock and thrusting it into the girl's tight pussy.

"Oh fuck!"

McKenzie's voice cracked awkwardly. The sound of it shocked her. It reminded her more than anything of her brother's voice when he started going through puberty. That thought disturbed her, but it wasn't enough to deter her from her mission: plowing this hot little slut.

Attaboy! Give in to your base impulses and fuck this bitch!

"Ugh, I'm not a boy!"

McKenzie slammed her throbbing manhood as deep as it would go. The inhuman rod tingled and itched with forbidden lust that cut the girl to her core. There was something deeply wrong about what she was doing. It was a betrayal of her fundamental womanhood to take another girl like this, especially with such a profane and masculine tool. Her womanhood was slipping away, replaced by something bestial and wicked. Did that mean she would stop? Fuck no!

Not a boy? You could have fooled me! You certainly know how to use that big, throbbing cock of yours.

"Shut up! Get out of my head! Oh, ugh, ngh. Why does this feel so good?"

"Yes," Annie whimpered. "Fuck me, McKenzie! It feels soooooo gooooooood."

"Fuck, you're still so tight! God, you feel amazing! You smell good, you feel you good, you look good! You're going to drive me insane with this perfect body!"

That's it, let it all out my son. You are in transition and need all the sexual energy you can gather.

"Transition? Sexual energy? What the hell are you, ugh, talking about?"

Your body is still growing as you continue to fuse with my lieutenant's tainted flesh. This is by no means your final form, my dear boy. Even as you pump yourself into this sweet little bunny, you're becoming more and more of a perfect servant to me.

"I'm not, ugh, your, oh God, servant!"

Oh, but you are! Even now, you are doing my work.

"I'm not doing shit for, ugh, oh, you! I, ugh, don't...oh God...belong, huh uh, to..."

Why don't we regroup in a little bit. You are clearly preoccupied!

"Wait, ugh, I...I want...answers! I...want..."

Annie suddenly grabbed McKenzie and yanked her down into a tight, slobbery kiss. Like a nuclear bomb, McKenzie's consciousness exploded. Her vision turned white as another terrifying orgasm wracked her body. The veins on her leviathan cock bulged as torrents of sperm began to erupt.

Energy surged through the shemale teen's body, starting in her balls and expanding outwards. The testicles glowed like two hot coals and then surged outwards, growing from overripe oranges into swollen grapefruit. The skin of McKenzie's scrotum grew tight and smooth against the monstrous organs.

The sudden expansion of McKenzie's balls kicked off a domino effect in her body. Changes rippled outwards. Her muscles tightened and swelled and her bones cracked. Her abs pressed outwards against the smooth skin of her belly. Her legs and arms lengthened and tightened, giving her a lean build full of strength and athleticism. Her breasts, already a handsome pair of C's, bulged into D's. Her cracky, pubescent voice suddenly deepened and darkened as a distinct bulge formed on her throat. Her lips plumped and her skin softened while the angles of her face sharpened.

When it was all said and done, McKenzie withdrew her mighty flesh sword and clambered to her feet. She now stood nearly six feet tall. Her body pulsed with strange power. She felt so different, so wonderful and wrong. Her mighty cock, which seemed bigger and distinctly less human, sporting several bumps and nubs, dribbled pitch black seed onto the carpeted floor.

"I'm not your servant," McKenzie said in a voice that was not quite female, not quite male.

Are you sure about that?

Suddenly, rapid footsteps approached behind McKenzie. She turned and saw Miss Wilkins, one of the librarians. Wilkins was a petite middle aged woman with a graying bowl cut, big glasses, and a mousy demeanor. She gaped at McKenzie in shock and horror.

McKenzie's cock reinflated instantly.

"I'm not your servant," she repeated in her deep, sultry voice. "But I'll go along with this a little longer."

Miss Wilkins was pinned to the ground and gagged with McKenzie's thick manhood before she even had a chance to scream.
