You bet!

Dan knocked on his sister’s door, his dick already hurting as it pushed against the fabric of his pants.

It opened, revealing his sister in the same costume he’d seen her on her selfie, but with a few more adjustments. She had added a large hat, opened her corset to reveal as much of her large breast as possible, and wore long black boots. She still had the eyepatch and the parrot on her shoulder, but apart from all of the above, her pussy was fully exposed. She had apparently also shaved all hair in that area.

She bit her lower lip, walked backward and laid down on her bed, in front of him, spreading her legs.

“C’mon in, cabin boy.” She said.

He stared at her and just walked a few steps before he stopped.

“I’m no cabin boy, girl, I am your captain.” He said. “Come help me take off my clothes.”

She stood up, joined him where he was and took off her hat before placing it on her brother’s head.

“Aye! Captain!” She whispered, before giving him multiple kisses.

She started on his lips, but then gradually moved down, taking off his clothes on the way, until she was kneeling down, lowering his pants and letting his dick fall in her mouth.

The stuffed parrot was now against the side of his leg, tickling him, and Lisa brought a hand to her pussy to start working on getting wet for her brother.

Dan grunted as she started moving her head. With each move she would bring his cock as far inside as possible, then retreat while closing her lips on his shaft, and running her tongue on it.

He grabbed her hair, pulled it and grunted.

She kept bobbing her head at different speeds, sometimes going faster, sometimes much slower, looking him dead in the eyes. She would also let go of his dick, only to lick it with her tongue, before letting it slide between her lips again.

After a couple minutes, Dan started breathing faster, and Lisa let go, wanting him to fuck her and being aware that he’d be less likely to do so if he cummed before he had a chance to get inside her pussy.

He frowned, surprised, but then pushed her violently on the bed before kissing her with passion. He wanted her so bad, he was going to fill her with a torrent of cum, he thought.

While still twirling his tongue inside her mouth, he moved a hand to her corset and pulled the laces, letting her huge tits bounce free and fall on the side under the effect of gravity.

He grabbed them and pushed them to have his face buried as Lisa moaned. They were so soft and warm. Dan felt like he could die happy, simply choked to **** by these wonderful bits of flesh.

Meanwhile, Lisa had slowly moved to align her pussy towards his dick, and raised her hips to brush against it.

Dan took the clue, and moved down, sliding inside her as she moaned even louder.

A giant smile of satisfaction appeared on her face, as Dan started thrusting his cock, enjoying the feeling of her wet pussy.

He soon grabbed her and turned her around, so he could fuck her doggy style.

He took her arms and maintained them behind her back. Her tits were now clapping in rhythm as she screamed with apparent pleasure.

And, just like that, he grunted and filled her with his semen just when she orgasmed as well.

They both dropped on the bed, panting, and Dan was surprised not to see her try to convince him to fuck her again.

“You're not... going to try and convince me to have sex with you again?” He mumbled, out of breath.

She rose her head, her eyes filled with hope.

“Do you want to?” She asked.

“No! No! I’m done for now. I was just wondering…”

She grabbed a pillow and let her head drop on it.

“Yeah…” She said. “That’s what I figured. I want to respect our deal. We do it when you want, not when I want.”

“Well yeah!” Exclaimed her brother. “Otherwise we’d spend all of our time doing it. We’d die of exhaustion.”

“I know…” She replied, sounding quite sad.

Dan grabbed her in his arms and settled against her naked body.

Lisa let him do, hoping being that close to her, his dick against her ass, would soon give him some dirty ideas.

“Anyway, captain!” She said. “Did you like it? Fucking a pirate?”

Dan laughed, much to Lisa’s surprise.

“I actually did.” He admitted. “But I don’t really care about the pirate costume or any of that stuff, for that matter. I actually made it up to see if you’d do it.”

She threw a pillow at him.

“You piece of shit! I spent the day running around town to find the right costume, and I even looked online for pirate slang!”

“Yeah! That’s funny. I have to say, though, it did turn me on more than I expected.”

She smiled.

“Good.” She said. “I want you to enjoy sex with me, so you’ll do it again.”

“I know.”

He nested his head against her neck, kissing it gently.

“So?” Lisa asked. “Did you fuck Sharon today?”

“Not exactly. She gave me a blowjob, though.”

“Is that going to be a regular thing?”

“Nah!” He said. “I’m done with her.”

“Good!” Exclaimed his sister.

Dan realized she was trying to assess who he was having sex with, as it reduced her chances of doing it with him.

He grinned and added :

“I found someone else, though, that I’ll soon fuck on a regular basis.”

“Who?” Asked Lisa, suddenly worried.

“A police officer I had an encounter with. Let’s say I made her want to play good cop with me.”

“Protect and serve, right?” Mumbled his sister.

“Exactly! That’s what I told her she wanted. To protect and serve me.”

“I see. And how many women do you intend to use your power on for sexual gratification?”

Dan sighed.

“Listen, I’ve been having sexual fantasies involving you since you were 16. Seeing how enthusiast you are about me fucking you, I’m not going to stop anytime soon. I just want to add some variety to my… sexual diet.”

“A harem…” She said.

“Why not!” He approved. “But you’ll always be a part of it, sis.”

She rubbed her ass on his dick.

“You are such a pervert, big brother!”

He nodded, rubbing his nose on her neck.

“Actually…” He added. “There’s a few things I’d like you to take care of if I am to keep fucking you.”

“What?” She asked, worried.

“Well let’s say that mom is probably going to be a bit busy for the time being, and I suspect she won’t be here any more to take care of us the way she used to.”

“What?! Are you saying you want me to do all the chores in the house?”

“Yup!”

Lisa turned around to face him, her big tits bouncing before resting on his chest.

“Listen to me, Dan!” She exclaimed. “I want to fuck you, not be your little ****.”

“That can be arranged.” He said, staring at her.

Lisa opened her mouth but said nothing. Her brother leant forward and kissed her on the mouth. She let him do it, moving a little so her tits would rub against him, and raising her leg to brush it against his dick.

Unfortunately for her, he broke the kiss and stood up from the bed.

“Can I count on you for the chores or do I have to make you do it?”

“Yes!” She exclaimed. “I’ll do it! Just don’t make me want something else!”

He grinned.

“Good girl!”

He picked up his clothes from the floor and walked out. Just as he was about to leave his sister’s room, she sat down on the bed and asked :

“Could you make me want to have sex with you AND want to do the chores?”

She had just realized that as long as she still wanted to fuck him, she did not care about any other change, and this one would make her enjoy the chores a lot more.

Dan froze, and slowly turned around.

“What?” He said, confused. “I thought you did not want me to use my power on you again.”

Lisa’s head started spinning. She could tell her purpose was shifting again. She was getting used to it, and so she simply remained still for a second, letting her mind settle.

She wanted to make sure he would not use his power on her again, she thought. She NEEDED to make sure he would not use his power on her again.

She blinked. Why would he make her want that? She wondered.

This made no sense.

“No you are right!” She blurted. “I’m good just the way I am. I’ll do the chores and you can still fuck me anytime you want!”

She **** herself to smile at him.

He nodded and left the room.

“He changed me by accident…” she whispered.

He had not realized what he had done, meaning he wasn’t aware that she no longer wanted to have sex with him, or that she wanted to do anything to stop him from using his power on her again.

She had to find out what to do. Obviously if for the time being she kept doing what he expected, he would probably leave her the way she was, but she could not be sure of it. This was a good strategy for the very short term, to pretend she still wanted to have sex with him, but in the long term she had to find a way to ensure he would not change her ever again.

She opened her eyes wide.

“I just need to kill him.”
