Limitations and Sister

“Are there limitations to what you can do?”

Matt was laying in bed, racking his brain to figure out the best way to use and **** his newfound parasite friend.

*There are several requirements. By the Ethics of Parasitism, I am to help fulfill requests so long as following said request does not drain me of more energy than I gain. I would like to leave your body at some point and regain my own form.*

“Alright, so, what, you’ll tell me if it’s too much?”

*No. Rather, I can give you time estimates depending on what you suggest.*

Matt paused, thinking it over. This sounded good, but he’d need to be careful then. He didn’t want to wait for weeks just to see some minor changes, he wanted to see every step of the way.

“Alright, so, let’s go with my sister this time.” He thought for a moment. “How long would it take for you to turn her into as big a pervert as me?”

*That would take a couple of weeks.*

Damn. “Alright, how about making her bi?”

*Bi? I presume you mean bisexual, given what I can ascertain from your mind. As for that, she already feels attraction to all genders.*

Matt blinked in surprise. He hadn’t expected that. His sister was bi… good to know. “Alright, uh, can you make her attracted to me?”

*That would take at least one week, given your current relationship.*

It was worth a shot. Would probably have to get over the **** hump. The man cupped his chin, thinking. “Can you… make her lust after mom?”

*That would take one night.*

Matt’s eyes shot upward. “What?! Why doesn’t that short time extend to me?”

*Because she doesn’t care for you, but she has strong feelings about your mother. Adoration the main one. Respect the second.*

“Alright, then let me change that.” He got up and started to pace. “Can you make her lust and fantasize about mom becoming a slut?”

*That would take a full day, including the night.*

“Then do it.”

Emily returned to her room for the night, putting everything away. Her room was neat and tidy, exactly as she intended to leave it before camping. The white walls and pink motif fit her, though only just. She was debating moving on to more mature colorings after high school was over. One more year.

Her mom peaked her head in the door. “Sweetie, mind helping me with dinner tomorrow? I need to leave part way through to pay Mrs. Silva a visit.”

“Sure, mom.” Emily hung up another shirt. “What’re we making?”

“Just some skewers. Tomatoes, mushrooms, a bit of steak.”

She gave her mom a thumbs up and was about to suggest adding a side to that when a voice rang through the house. “Moooooom! Come here real quick!”

The matriarch rolled her eyes, waved, and left. Emily shook her head and finished her unpacking before spending the rest of the night relaxing in her room, texting some friends cute photos of her camping trip.

And, to her closest friend, a couple of choice pics of the “play partners” she got while up there. She smiled, her own pussy moistening at the memories.

Before she could masturbate or in any way ease the tension of her arousal, a severe pain rolled over her head. Like a cement truck crashing into her, she blacked out, not even changing out of her clothes.

She woke up the next morning wetter than a pool. Her body was a live wire, each movement sent a new wave of pleasure and need through her. She cast her eyes over to the clock. 10:05 am. She was already oversleeping, and her mom would check in on her if she didn’t get downstairs soon.

Emily combed her brown hair. No point letting herself look bad, even for breakfast. She threw on new clothes and all but skipped down the stairs. Her pussy was still aching. She couldn’t recall any of the dream that caused this.

Oh well. She’d remember it next time she had alone time.

As she turned the corner to the kitchen, she spotted her mom and her eyes locked onto her ample breasts. Perfect globes of fat, probably big aerolia, perfect for biting and sucking. If she had finally gotten her horniness under control before, it was once again a raging inferno.

“Hello, Sunshine,” her mother said walking over to the table with a small plate of pancakes. She didn’t notice her daughter’s lecherous stares.

“H-hi, mom.” Why did she look so good today? Why was she perving on her mom?! Emily broke her stare and sat down at the table, reaching for a fork and knife. “Thanks for breakfast.”

“You’re welcome.” Her mother smiled and Emily noticed she was wearing the same clothes as yesterday. Probably just didn’t have any clean ones and needed to do laundry.

As if on cue, her brother came downstairs. He still smelt slightly from his room, teenage boy sweat and probably cum. He was dirty, disgusting, and she hated it. She was tired of people trying to use her brother to tear her down. If only he had just a few extra brain cells dedicated to hygiene, he might actually have a girlfriend.

His gaze was first on her and then their mother. She saw the hunger and arousal in his eyes. Fucking pervert, staring at his own mother. Her own gaze returned to their mother and she subtly bit her lip. Their mom’s shirt was showing ample cleavage.

Fantasies flooded into her mind, of her mother on her knees servicing cocks and pussies. Of her covered in cum. Wearing booty shorts and a tank top, them together at a strip club dancing. She couldn’t help herself. Clenching her thighs, more fantasies entered her mind. Her mother being a whore. Forcing her mom to eat her out in their bed. Breaking her mom into her own personal slut.

“Are you two going to eat?”

Their mother’s word shook Emily from her fantasies. She looked at mom’s plate, noticing half the pancakes were eaten. She nodded nervously and turned her eyes to focus on her food and not on their mother.

But her mind was entirely focused on the Milf at the end of the table, and the naughty things the daughter wanted to do to her.
