“Nhh, ah, th-that’s…ahn.”
He gently licked her clitoris.
A first-rate trainer like Shibaki had learned she was most sensitive there when he had first touched her on that first day. Until today, he had intentionally avoided much stimulation there and focused on vaginal sex, but…
“There’s no denying it with all these sticky juices flowing out. I’ll be using this today. Heh heh heh. Let’s hope you can still move your hips afterwards.”
The soft bead looked like it would be hard to grab, but the trainer accurately caught it between his lips. Now was the time to show off his technique as a natural lady killer.
He could probably put these skills to use in playing a wind instrument. He rapidly wiggled his tongue every which way.
“H-hyah!”
Before long, Koishi’s hips, back, and then entire body began to convulse in time with his tongue.
But he showed no mercy. His fingers kept her vagina spread while it tried to squeeze shut with her convulsions and the persistent screwing movement of his tongue attacked her clit.
“Ah, ah, ahhn! St-stop!”
“Don’t stop sucking. What kind of selfish whore forgets to pleasure her customer?”
He stopped only for as long as it took to give that order. And that gap was only used to create a rhythm to the pleasure so the stimulation did not become painful.
“Ah, ah…wait, no…I’m going crazy!”
Her cute butt tried to bounce up and escape, but his hands held it firmly in place.
She had no way of escaping the great vortex of pleasure created by the screwing motion of his tongue. She could only send a rippling motion through her vaginal flesh and squeeze her asshole shut in front of his eyes.
“Ahhn! Ah, yessss!”
Something other than despair filled her cries.
It was all progressing as the trainer wanted.
There was only one way to escape. The nerves of the clitoris were sharp but only on the surface. Just like the pain of an injury could be reduced by convincing yourself it did not hurt, you could reduce the electrical signals known as pleasure by rejecting and suppressing that rising sensation. In other words, it was easy to “bear with it”.
But Koishi did not know that, so she was at his mercy.
This carnal pleasure should have been shallow, but she subconsciously welcomed it.
She was likely unaware of it herself, but some deep part of her had decided to accept the pleasure instead of rejecting it.
That emotionless girl from a few days ago could have endured this, but now it had a dramatic effect on her. This was the result of the training, so the man smiled in satisfaction.
“Focus on that sensation. You will soon receive that feeling you love.”
“Ah…”
He attacked her verbally as well.
Never stating anything explicitly was something of an agreement they had between them, but what was the final result for her in everything he did?
And at the same time…
“Ahh…ah, ah, ah, ahh! I’m…going to cum. I’m really going to cum!”
Announcing that when it happened was her end of the contract in which he gave her this pleasure over and over. The act had been imprinted on her, so she naturally raised her voice.
She even pushed out her hips toward the man. That pose was just like a wild leopardess, so it was simultaneously beautiful and primitive and she could not restrain the demands of her instincts.
The extreme pleasure had implanted the trainer’s teachings within her to the instinctual level.
The trainer gave one final lick and then squished the clit with his pointed tongue tip.
“~~!”
She gasped like a switch had been pressed.
“Ah, ahh, ah, ah…”
She had no idea how embarrassing an act she was engaged in as she pushed her beautiful butt against the man’s face.
“Ah, I’m cumming, cumming, cumming!”
Her voice echoed through the room as she announced her climax.
The girl’s clitoris trembled like the saliva still coating it was enough to provide pleasure and her shoulders trembled along with it.
She was only half conscious and she collapsed limply onto the bed once she was removed from the 69 position. The convulsions of pleasure disturbed her breathing before she regained consciousness and that showed just how intense a climax it had been.
“That was a clit orgasm. I’m sure a slut like you can’t wait to try that out again. Well, not to worry. I’ll make sure you are so hooked on it you can’t get to sleep without one of those.”
The man smiled as he lay on top of her in the missionary position.
The tingling of climax still lingered with her, so now was the time. He had said this lesson was about her blowjob technique, yet he pressed a barely-sucked penis against her twitching vagina.
“But something even greater can be found in the female body. You already know what that is, don’t you?”
“Ee…”
“A vaginal orgasm.”
“Gh! Ahn!”
He pushed all the way inside that decently loosened-up vagina. He had made sure to keep spreading it even while stimulating her clitoris, so it accepted his giant thing without tearing.
“Ah, ah, ah.”
But even after three days, she was still not used to that great size. She was still not mentally prepared, so her eyes widened and she writhed in shock.
But he shoved it in all the way to the base regardless.
“Surely you’re used to my size by now.”
“Ah, no, it’s too big. I can never…get used to it.”
“Whatever you might think, your slutty pussy is happily devouring it. Heh heh. Your clit even perked up again as soon as I put it in.”
She was actually just as tight as on that first day and the innocent folds were biting down on his penis hard enough to make penetration difficult, but he confidently pushed right through all that.
As innocent as her vagina might be, her mind was a different matter. He knew the soul of a sex slave had begun to take hold deep inside her.
And her promising masochism was powerful nourishment for that soul. She instinctually wanted men to treat her more roughly and to be remade.
“You are my slave. Do you understand that, Koishi?”
“Ah…”
When he looked her right in the eye and said that, she looked away with a complex and somewhat bashful look.
She had not fully accepted it, but he could tell some portion of her had accepted it.
“Ahh, ahh, it’s so thick, ahh, so thiiiick!”
She stretched out her back to bear with the sensation of it pushing inside her.
And the flesh inside her sucked at it with even more stickiness than before.
The clit orgasm must have worked wonders. Her body was begging for the next pleasure from this invader that always brought her to climax.
He had called her a slave and her vagina was remaking itself to match.
“Heh heh heh. Good girl.”
Confident he could move on to the next phase, Shibaki chose not to thrust and instead embraced her slender body while they were connected.
“Ah…wh-what are you doing?”
This unexpected embrace caused her to blush in confusion.
The way her vagina tightened a bit showed that she actually liked this. He kept his hips motionless and waited for her internal flesh to grow fully accustomed to the penis.
But he had to move some, so he slowly moved the head shoved inside her.
“This is your womb. Can you tell?”
“Eh? Ah, hh.”
The previous sex had been too overwhelming for her to notice even if she had felt it. She looked like she could hardly believe this sensation of someone touching her in that deepest part.
“There are no nerves in this area. That means no pleasure or pain.”
He moved his cannon as gently as he could to send a vibration into that dead end.
“But focus on your womb. I called it a vaginal orgasm and you can indeed cum without nerves. That is the lesson you must learn.”
“Vaginal…orgasm.”
“Once you learn this, there is no going back. Heh heh heh. You’ll be addicted to cock.”
“But…”
A dark pink flush covered her face that looked surprisingly youthful when viewed head on.
