Dan, a 22 years old unemployed guy living with his mother and little sister.

Dan had awakened from a strangely vivid dream. While its content was slowly fading from his memory, two sentences were still lingering, looping through his mind as he made his way to the kitchen.

“You are now the master of purpose. People will want what you want them to.”

He shook his head, trying to dismiss these weird statements. Today was going to be a big day for him, and he needed to wake up from his current slumber.

He made some coffee, grabbed some cereals, and sat down at the table, letting the early sun rays, coming through the window, warm him up.

After a few minutes, chewing his kellogs and sipping on his cup, he was finally starting to feel more like himself.

“Good mornin’” Said a sleepy voice.

His sister, Lisa, had just entered the kitchen.

He turned his head and couldn’t stop himself from keeping his eyes fixed on her, a tiny bit too long. She was now opening the cupboards to grab something to eat.

She was a 19 years old beauty. Ex cheerleader, she had spent her highschool years among the most popular students, taking good care of her appearance to slowly climb the ladders of the teenager’s world. She had the body for it, and she had been taking good care of it. She was small, but had plenty of curves, including breasts that the blue pajamas she was currently wearing could hardly cover. Her face was filled with freckles, she had bright green eyes, and she had long red hair attached in a bun.

Dan had to admit, at least to himself, that while it wasn’t normal to lust after your own siblings, he had long been having fantasies about her. He tried justifying it by thinking that no one in their right mind, not even a brother, could avoid being attracted to such a body.

Lisa stared at the last cupboard she had opened and sighed.

“Is that all we have for breakfast this morning?” She asked, disappointed by the lack of choice. Her mother usually made sure to stack the kitchen with enough food for an army, but today it seemed rather empty.

“Yeah…” Replied her brother, still stuffing his mouth with his last cereals. “Mom didn’t have time to go do the groceries this week. She’s supposed to do it before coming home this evening.”

“Shit!” Lisa exclaimed. “I hate cereals…”

Dan laughed.

“Well you don’t have much of a choice this morning, do you? What is it you’d want to eat?”

His sister froze in place, suddenly filled with the most intense sense of confusion she had ever felt.

That was a good question, she thought. What was it she actually wanted to eat?

She started running, in her mind, a list of things she would usually enjoy for breakfast. She was now almost panicking. Somehow it seemed to her like finding it out was both impossible and vital. Why? She didn’t know. Nothing she could think of seemed to be what she was looking for, but she just couldn’t stop. She needed to find what she would want to eat if she could.

Dan looked at her, raising an eyebrow. Her sister was immobile, staring at the almost empty cupboard and she appeared to be… shaking?

“Are you alright?” He asked, concerned.

Lisa turned around. She was now on the verge of tears, which made Dan even more confused about what was going on.

“I don’t know what I’d want to eat…” She explained with a shaky voice.

Her brother shook his head, surprised that something so unimportant could be the source of her distress.

“Well…” He said. “Don’t you usually want pancakes in the morning?”

Lisa breathed out of relief and smiled. Yes! She thought. This made total sense. This was what she was looking for. She wanted pancakes in the morning. She NEEDED pancakes in the morning.

Her sudden flash of happiness did not last long, though, as she realized the empty kitchen might be a sign that she did not have enough ingredients to make any.

She started opening all the drawers, looking for flour, and throwing away anything that she’d grab that were useless to her in her newfound quest for the perfect breakfast.

“Waow!” Shouted Dan, jumping from his chair to grab the stuff that was ending up on the floor. “What the hell are you doing?”

“I need to make pancakes!” She shouted back, now horrified by the obvious lack of the needed ingredients.

Her brother froze in place, suddenly remembering the last sentences from his dream. This definitely had to be a coincidence and yet… his sister’s behaviour was totally unusual. She usually was a pretty cool-headed girl.

Lisa stopped what she was doing, grunted some incomprehensible words, and suddenly walked out of the kitchen. Dan followed her in the corridor, almost running after her.

She stormed towards the front door of the house and opened it, barefoot and still in her pajamas.

Her brother moved past her and blocked her path. She tried to push him away but he held his ground.

“Let me go!” She shouted.

“Wait!” He exclaimed. “Where the hell are you going?”

“I need to go buy pancakes!”

“What?!” He replied, flabbergasted, “The nearest store is 5 miles away! You’re gonna go there on foot, in your pajamas and without any shoes?”

“I don’t care! Just let me go!” She almost screamed. “I need to get there before morning is over!”

He had to use all of his strength to stop her from going any further. She was in a fury.

Had he done something to her? Was the dream real in any way? It couldn’t be and yet…

“Wait!” He exclaimed again. “You want to get back inside!”

Lisa froze. She did want to get back inside, now that he was saying it. She NEEDED to get back inside. Any desire to eat pancakes were suddenly gone. Getting back inside was the only thing that mattered.

“You’re right!” She said, calmly.

She simply turned around and walked back to the front door, while her brother watched her with his mouth wide open.

She stopped a couple feet away from the still open door, took a deep breath, and walked in.

The satisfaction of finally doing what she needed to overwhelmed her. She was ecstatic. She let this sudden wave of pleasure rush over her while Dan, finally out of his torpor, followed her inside the corridor.

He couldn’t believe it. He really made her want to get back inside just by saying it. She now looked like a zombie, thought, and he didn’t really know what to do from there.

Suddenly, she frowned, and rushed back outside.

Dan shivered. Maybe he had been wrong. Maybe he didn’t suddenly find himself with superpowers.

What followed next got him pretty confused for a moment.

Lisa, now in front of the house, turned around again and walked back in. Then, she did it again, and again, and again, with a smile on her face.

Dan put a hand on his forehead, finally understanding what was going on. He told her she wanted to get back inside. Even after doing it, she still wanted to do it, and therefore had to leave so she could do it again.

He thought about it for a second, and then said to her :

“Lisa. You want to watch tv.”

She stopped right in her tracks, and ran towards the living room. There, she grabbed the remote, jumped on the couch, and turned the television on.

Dan closed the front door and joined her, sitting down next to her, still in shock.

He watched his sister open the netflix app, and resume her current favorite show.

It seemed the “instruction” he had given her still gave her a bit of leeway. He was relieved to see she still had a personality underneath, and was not just mindlessly watching a random channel.

She seemed, again, pretty happy about doing exactly what she now wanted to do, smiling like it was the best day of her life.

Dan had to wonder, thought, if this was going to last forever, or if she would wake up from this weird state at some point.

He looked at her for a moment, and blood started rushing down to his crotch. He was now suddenly aware that his newfound ability could allow him to enjoy her in ways we couldn’t even dream of before.

“Do you like this show?” He asked her. Testing her state of mind.

“Yeah it’s pretty great actually!” She replied.

She then started explaining why she enjoyed it, going into details, like she would usually do when she would be talking about something she enjoyed. Apart from the dumb smile on her face, she now seemed to be herself. This was to Dan another confirmation that his “power” was not making her mindless. She just wanted what he said she wanted, but was still herself. But, he wondered, how much did she want it?

“Lisa?” He asked. “Would you like me to give you a hundred dollars?”

“Sure!” She said. “Why would I say no to that, dummy?”

“I’ll give you a hundred dollars if you turn the tv off.”

“No way!” She replied. “You can keep your money.”

“A thousand dollars?” He tried.

“Not even for a million.” She exclaimed, giggling. “And I don’t think you have a thousand dollars anyway.”

She had not even turned her eyes from the tv once since switching it on, Dan realized.

“I’ll give you a hundred dollars if you stop looking at the tv for two seconds.” He said.

“Just leave me alone, Dan! I’m watching tv”

Alright. He thought. It seemed like nothing could convince her of not doing what he said she wanted to do. Not even a million dollars, as she said.

He was really tempted to ask her something… more intimate, but he was still too scared of the unknown implications of what he could apparently now do. He didn’t know how long it would last, and if it didn’t how she would react from finding out her brother took advantage of her. He also had no idea how to “fix” her, as so far he only had been able to switch one “instruction” with another.

He therefore first needed to see if it would wear off. He needed to have her do something she wouldn’t usually do and wait to see if she would stop by herself, but it needed to be something safe.

“Lisa?” He asked. “You want to clean the house.”

Her sister blinked. Why was she watching tv when she obviously wanted to clean the house? When she obviously NEEDED to clean the house? She looked around her, noticing the dust on the furniture, the dirt on the windows, and every tiny things she now wanted to take care of.

Dan watched as Lisa stood up and started cleaning everything, whistling a happy tune, apparently perfectly happy to be doing it. He was hard again. He could not believe such a thing was really going on.

He was supposed to go out and find some work for the summer, but he now just wanted to stay and watch as her sister was completely under his power. He wanted to know if she would stop, if she would go back to being normal again. If not, his dick was already warning him that he’d have a hard time stopping himself from doing anything more unethical with her. He was slowly coming to terms with that fact.

He kept an eye on her for about five hours. She showed no signs of stopping, but he was relieved to see she would occasionally stop to go to the bathroom, drink water, or even to grab something quick to eat in the fridge. When he asked her why she stopped cleaning for that, she replied :

“Well I can’t keep cleaning the house forever if I die of starvation, can I?”

So, Dan thought, she was thinking in the long term. She wanted to clean the house, for as long as possible, and therefore could take breaks so she could do it forever…

Forever. The word lingered in his mind.

His mother would be back in a couple of hours. If he wanted to try something today, it was now.

He walked close to his sister. She was doing the dishes now, as it was one of the only things left to do. The house had never been this clean.

“Erm…” He stuttered. “Would you like to show me your tits?”

He wondered if it could work like that, as a question.

Lisa dropped the sponge in the sink. This was a fair question. Would she like to show him her tits? He was her brother. This was highly inappropriate. Still, now that he was asking about it, it seemed obvious to her that she indeed wanted to show him her tits. She NEEDED to show him her tits. She was not about to let stupid moral questions stop her from doing her… purpose? Yes, purpose. That was the right word, she thought.

“Sure!” She said, with a smile.

And with that, she grabbed her pajamas and pulled them above her head before throwing them on the kitchen floor, her boobs bouncing free.

Dan was hard as a rock. His sister was standing up, in front of him, fully naked. She was even sexier than in his wildest fantasies. Everything about her body was perfect.

She smiled, her eyes fixed on his as he was looking straight at her breasts.

She was so happy, doing what she wanted to do. Doing what she needed to do.

Yes, her brother was obviously enjoying it, and she was thinking about how much of a pervert he was, but damn was she glad he was, otherwise she’d have to convince him to see her tits, and she needed him to see them.

After a minute or so, Dan moved a hand forward, slowly, attempting to touch these amazing boobs.

Lisa moved back a little, and he stopped mid-air.

She was a bit confused about the situation. She wanted him to look at her tits, this was her purpose, but she didn’t want him to touch them. He was her brother after all.

“Who said you could touch them!” She exclaimed.

“Sorry!” Replied her brother, visibly shaken. For a second he turned his face away from her.

“Wait!” She shouted. “You can still look! Please!”

She was playing a dangerous game, she realized. She needed him to look, and she didn’t want him to touch, but stopping him from doing so could push him away, and she needed him to keep his eyes on her breast.

“You know what?” She said. “You can touch, but just keep staring, ok?”

Dan was surprised. For a moment he had thought she was coming out of it. He moved his hand again and slowly put it down her right boob. The sensation was fantastic. He slowly grabbed it. Her tit was warm and soft. He felt like he was losing his mind. He ran his hand along it, rubbing her nipple on the way. Her sister seemed unfazed, maybe even a bit uncomfortable, but when he looked at her eyes she just said :

“Don’t worry about me! Just worry about my tits! Just look at them!”

He couldn’t stop himself, he desperately needed to cum now, and he desperately wanted her help for that.

He asked something he would have never dreamt of asking her.

“Lisa? Do you want to…”
