A Sibling's

“What?” She asked, pretending to be hurt by that as she mushed her big pillowy tits against his back even more. “But you couldn’t get enough of them last night. Mmm, they’re still tender too…“

Steve blushed hard, unable to form any truthful words of denial.

“I mean, we’ve already crossed that line that brothers and sisters should never cross.” She said, whispering her seductive words into his ear. “Why don’t you show me what you’ve really got, now that you’re back to your old self?”

“I have a better idea.” Steve said, leaning back into his sister’s embrace with a very serious look on his face as he turned to face her.

He felt her heart begin to pound and saw a nervous smile form on her lips, likely getting the wrong idea about his next words were going to be.

“How… How about you give me some time to think this over.” He said, deep down in his heart not wanting to see that smile turn upside down by outright rejecting her. “And in the meantime, you can clean go clean my kitchen.”

Monica’s cute face, perhaps the cutest face he’d ever laid eyes on, pouted at him.

“You’ve got a computer program in your lap that can do literally anything. Just use it to magically clean up and take me back to pound town, Stevie.”

Steven thought about that for a moment, then smiled.

“Sure, I can do that.”

“Wait, for real?!”

“Sure.” He chuckled, and his fingers began dancing around the keyboard. “The first half, anyways.”

[Subject’s sister will put on some clothes and clean the mess in his apartment’s kitchen.]

As soon as he pressed the Enter key, Monica gasped as her body began to move on its own.

“Rude!” Was Monica’s parting word as she quickly skipped out the door, her perky curves jiggling around.

“That was awesome.” Steve laughed to himself, then got up and threw on a pair of green shorts and a loose-fitting white shirt before leaving his room with his sister’s laptop folded up under his arm.

He planned on exploring the program some more, but first he was off to the bathroom to take care of the steel python bulging in the front of his shorts.

However, after busting the largest nut he’d ever seen, he realized that it still felt fresh and ready to go.

“Great.” Steve mumbled to himself with a roll of his eyes. “If this keeps up, I might just give Monica what she wants… After she’s done cleaning, of course.”

And with that simple consideration, certain ideas began popping into Steve’s mind.

Monica grumbled as her body knelt down beside the couch and began digging through a suitcase full of her clothes for something decent to wear.

Unfortunately, everything was quite a few sizes too big for her.

At least her annoying conditioning was allowing her to choose something herself, she thought. Monica eventually settled on a very loose yellow tank top and gray sweatpants that looked a little silly on her, but she took solace in the fact that her attire wasn’t bad for showing off her bouncy cleavage and the notable curve of her ass after she put them on.

Her feet then carried her to the kitchen, and once there, she bent under the sink to grab some rubber gloves and cleaning supplies.

It felt strange, she thought. Her body moving on its own wasn’t unpleasant, and it almost seemed as though she was choosing to do whatever it did on her own. If she was doing anything else in the world, it’d actually be kind of hot.

It’s too bad that cleaning up was one of her least favorite things in the entire world to do…

She heard soft footsteps in the living room shortly before the TV was switched on and began playing an old popular show that her brother enjoyed listening to reruns of.

Part of her was hoping that he would switch it to porn, but Monica knew better.

Her brother was a sexy beast that could fuck like a machine, even before she amped up his cock and temporarily cut his IQ in half. Sometimes she would be able to hear him and his now ex-girlfriend from down the hall as she was hanging out in his living room being a lonely slob. The thing was, he was vanilla and prudish when it came to anything sexual in nature. He didn’t even like going shirtless around the house, for fuck’s sake! Denying her of seeing the toned upper-half of his body. The audacity…

If only his mind was as deranged and perverted as her own, she thought to herself. Hell, she probably should’ve just kept him in that stupefied state, and…

“No.” She whispered to herself, then sighed.

She loved him too much to do anything he’d hate her for.

Monica was glad that he didn’t hate her already.

“How’s it going in there?” Steve called out to her from the living room.

“Fine, I guess.” She called back, her tone less than enthused as she scrubbed at the pan full of burnt ground beef, causing her tits to pleasantly jiggle around underneath the loose straps of her tank top. Fuck it, since she and him already fucked like rabbits, she didn’t see a point in holding back the inner thoughts that she’d usually keep to herself when they were alone together. “It’d be a lot better if I had your cock in my ass, though!”

She said, grinning wide and giggling with satisfaction. He was probably in there right now blushing like a dork, not knowing how to respond to such a vulgar and-…

Monica’s train of though was cut off when she felt something slide between her perky cheeks and prod her tight asshole.

Even as her body moved on its own, continuing to scrub the pan, she was able to look back over shoulder and at her curvy butt with wide eyes.

Nothing was there, and her clothes were still on.

"Hope this helps!"

Nevertheless, Monica let out a gasping squeal when a steely, overly-thick, and very twitchy object slid ride into her ass without much of any resistance.
