"Oh my, it seems that you are just fit for this school," the monster said. "But you're going to need to beg me more if I'm going to really fuck you. I need some... incentive." With that, he withdrew the tentacle, knowing that her now raging Hormones, caused by the aphrodisiac, were going to make her want it. He waited to see what she would do.

Severity blinked, surprised both by his withdrawal and how much she resented it. "Please- please, I'll do anything!" she said, watching him hopefully.

"Well then, aren't you being the little slut. Very well. From this point on, hmmm..." He'd never had this much control over a girl before. "How about from this point on, you call me master," he finally decided. "And you obey every order I give you."

(Yes, I know that was very corny.)

((It's cool. ^^))

"Yes, Master- anything!" she said eagerly. Her need filled her mind, pushing aside all other thoughts.

"Then lets begin... "
His member wasn't fully hardened yet, so his first command to his new slave was to message his cock.

Severity quickly began rubbing it up and down the huge shaft, a slight smile on her lips.

"My, my, looking a little bit too happy, aren't we?" said the monster, now feeling a little bit more daring. He raised a tentacle and brought down hard on her ass, a loud SMACK resounding through the room.

She flinched, her eyes widening slightly. "Oh!" she said softly, then paused. "I'm sorry, Master," she continued.

Oh man, a monster could get used to this.

"You're a dirty little slut aren't you?" said the 13-tentacled being, slipping a tentacle up to her ass. "You enjoy being a monsters slave, dontcha?"

"Mmm- yes, I do, Master," she said softly, feeling the tentacle approach her tight little asshole. "I'm such a slut..."

"Then don't hold back," he said, as he roughly pushed his tentacle into her ass, and lifted her up and placed her on his thick shaft a second time.
"Scream like the little slut you are!

Severity cried out, her back arching as he shoved his huge shaft into her dripping pussy. "Oh god, yes!"

Is it me just me, or is she getting even tighter?

"At a bitch," said the monster, pleased with his results. His tentacles began to stimulate her in ways no human could- touching her breasts, pulling her nipples, stuffing her mouth. "You will come again slave," said the monster viciously. He started going faster with his cock.

"Yes, please, Master!" she moaned, almost there. She finally came, her vaginal muscles squeezing his huge cock tightly.

"Well, well, we are having too much fun here. It appears some 'punishment' is in order here." He took out his cock, and his tentacles left her body. And the monster just stood stock still as the whimpering girl recovered.
