First target

As Jake was racing home he could see the world around him differently than before. Everything seemed much cleared and Jake could see every little thing in detail. It wasn't hard for him to look around while moving at full speed and it even seemed like he got less tired than before.

All of this was because his brain had become stronger and he could now more of it. But even though he was admiring the changes he still couldn't wait to get home and within minutes he arrived in front of the door.

Jake wasn't much of an athletic, but after his brain was unlocked it seemed even his physical prowess seemed to have been increased as he wasn't even that tired. Finding out this effect he swore to himself to start training his body even more so he would be able to protect himself if there was ever a need for it.

He opened the door and walked inside. Quickly scouting the house he saw only Kayla was present and Julia had left the house.

"Kayla where's mom?"

"Out to get groceries and some other stuff, she'll be back in a couple of hours."

Jake was ecstatic, this meant he was totally alone with his hot sister and could now test his newfound power on her.

After his brain unlocked he could feel his sensory abilities drastically increase. He could also feel his IQ rising and remembering this that he wouldn't have had remembered before his awakening.

So he knew it had worked, but he hadn't felt anything regarding the hypnotization ability his father had mentioned in the letter. Luckily his father had explained the method in the letter. All he had to do was look the target in the eyes and use his mental strength to descend them into a sort of trance state.

In this trance state, he would be able to give them commands and ask them questions which the target would answer truthfully.

Naturally, his father had also mentioned that the power wasn't limitless and the success highly depended on his mental strength and that of the target. If the target was smart or had a good mental capacity it would be harder to get them in the trance state.

But now that Jake's mind had evolved because of his brain's advancement he was confident in overpowering Kayla.

Kayla is extremely hot and a lot of people in the school admire her. Only for her beauty though as she isn't the brightest sheep in the shed. She has to do her best to get a passing grade for her classes.

"Kayla!" Jake called out to make his sister look at him.

"What is it?" She said a bit annoyed as she didn't like Jake's tone.

Still, Kayla turned towards Jake and looked at him in the eyes.

At that moment when Jake met Kayla's eyes, he sent mental energy into her brain, as per the technique mentioned in his father's letter.

Kayla felt a stab in her head after she got a splitting headache. But before she could even think about what was going on or want to relieve the pain appearing in her head, her eyes sunk and her body went lifeless, sitting in the same position she had, not moving a single finger.

Jake instead of feeling good he had succeeded sunk to the ground exhausted, his head was hurting like crazy. It seems like using this power of his used way more of his energy than he imagined.

But even though he was exhausted and the pain was surging in his head, he got up to look at the result of the hypnotization.

He stood up with trouble and walked towards Kayla who was still sitting lifeless. Naturally Jake was incredibly happy that he had succeeded, even though it had taken way more effort than he had thought.

The moment his mental energy went inside Kayla he immediately broke through her defenses and succeeded in his attack, but it had taken way more energy than he had though. Probably because he only recently unlocked his brain's potential did it cost this much energy to successfully hypnotize Kayla, who wasn't someone with high mental prowess which could make it harder for him to succeed.

Jake looked at Kayla and was ecstatic. Even if he waved his hands in front of her she didn't even blink. Then he went a bit further and both of his hands landed on top of Kayla's well-rounded breasts.

Jake felt amazing as these were the first-ever breasts he held in his hands, and they were some high-quality ones at that. Feeling nicely elastic, but still very soft. And this was through her shirt and bra.

Naturally Jake couldn't get enough of groping them and kept his hands moving all the time. Kayla though remained seated with a lifeless expression in her eyes, not seeming to even feel the groping of her breasts.

Then Jake said: "Kayla?"

Jake didn't know what would happen now. In the letter, it had said that someone who was in trance would answer every question truthfully.

"Yes."

Kayla actually replied even though it wasn't a question that made Jake experiment, even more, all the while his hands explored Kayla's breasts.

"How old are you?"

"17"

"Gender?"

"Female?"

It seemed to Jake questions like this would be answered perfectly, so then how about some spicier ones.

"Tell me Kayla are you a virgin?"

"Yes."

Jake was overjoyed as not only did she answer such a personal question without doubt, but her virginity was even still for the taking. Naturally Jake regarded that as his right to do from now on.

"Is there a boy you like?"

"No."

"Then what about your brother Jake?"

"He is a good for nothing loner. There's no way I would like him."

Jake got a bit annoyed hearing this, but then again it wasn't a secret as to how she thought of him.

"That's why you treat him so badly?"

"No, I treat him like badly, because he needs to stick up for himself, which he can only learn the hard way."

Jake upon hearing this sighed as he understood she wasn't all bad and actually had a reason for treating him so bad. But he didn't care about it that much, she was still in his hands and she would still be his.

Having heard enough, for now, it was time for him to truly enjoy himself, so he ordered her to come with him to her room, which she did without fail.

Jake sat down on her bed and made Kayla stand in front of him.

"Take off your t-shirt and pants."

Kayla immediately got to work and it didn't take long before she was only standing in her bra and panties. She had taken her clothes off in front of her brother without complaining.

Jake was very much enjoying himself as he saw his insanely hot sister stand in front of him, in only her underwear. Something he never dreamed possible.

Looking at her breasts which seemed to fill her bra up completely. Even her ass which was nice and perky. Jake couldn't wait for what was next, because what was better than seeing a beautiful woman in her underwear. Seeing her naked, so Jake without wait gave her the order to strip completely.

And within seconds, Kayla, his beauty of a sister stood in front of him with nothing on. Her breasts which Jake already knew were big, were even bigger than he thought. Naturally, his eyes couldn't look away from her unused slit.

Jake had to fight hard to resist the urge to just throw her on the bed and fuck her relentlessly. Because even though Kayla was naked in front of him, there still was no sign of emotion. Jake didn't care if she was still emotionless while he fucked her, but after thinking about it a bit with his new powers why not make it even better.

Fucking a beauty like Kayla would always feel good even if she didn't show any emotion. But what was even better was to shape Kayla's true personality into one his liking. Why not have her beg him to fuck her instead.

What would be better than having his sister, who treated him badly all these years suddenly come up to him begging him to fuck her?

There are plenty of beautiful women Jake could now fuck and throw away. Instead, he wanted Kayla to turn into something special. He wanted to train her into his loyal sex slave who would do anything for him.

He didn't want to achieve that by just upright changing her personality. He didn't know if this was even possible. To completely change someone's personality with hypnotism, especially not with his mental powers still at the weak side.

Instead, he would slowly tweak it, so Kayla's true personality would change into that of a completely obedient one. Fulfilling all of Jake's fantasies.
