A Hot Conversation with Jenn... the Slug

That night, I walked inside Jenny's bedroom with the slug resting in my hand.

I had been worried that it would try to get inside my ear, but as soon as I had gotten it out from the jar, it had remained motionless, gently glowing.

It was pretty dark, but I could distinguish my step-sister lying on her bed. Her face looked pale in the dim light of the street lamps shining through the window.

I moved my hand close to her head, and as soon as I got near her ear, the slug somehow jumped inside it.

Jenny moaned but did not seem to wake up as the creature vanished inside her head. She stayed like this for a few seconds before slowly opening her eyes and then sitting upright.

"Hey," she said groggily. "What the fuck are you doing in my room?"

She rubbed her eyes and turned her nightstand on.

"Wait a minute..." she said, looking at me. "I'm not myself, am I?"

"You tell me," I replied.

"I'm the slug! I remember now! " She exclaimed. "I couldn't remember it before because I left the memories here. I can't remember much on my own."

"Okay, listen! I need to know what you've done to my sister," I told her firmly.

Jenny appeared confused for a moment and then giggled.

"Ah! I found it! I made a few changes before I left last time. I thought you'd like it," she explained. "Seems like you've been enjoying it."

She winked, looking toward my crotch.

I blushed slightly.

"So? What have you done to her?" I asked again. "Exactly."

"I've rearranged some pathways. Make sure she finds it perfectly normal to do whatever you ask."

"Get naked," I ordered. She opened her mouth and remained still for a second before nodding. Then she stood up and started removing her pajamas. She was halfway undressed when she stopped suddenly.

"Hang on!" She said, turning her head toward me. "Are you trying to use her while I'm inside?"

"It took you a moment to notice it," I remarked.

"Yeah..." she mumbled. "As I said last time, Jenny does the thinking. I can alter it, but I can't do it for her. I've made her think obeying you was normal, so she thinks it is normal, and therefore so do I."

"But you stopped."

"I saw the thoughts going through the pathways I created. I can feel it," she explained.

She bit her lips and finished removing her pajamas. She was now perfectly naked, her body displayed in its full glory.

I could not help but stare at it. It seemed even more perfect than I ever imagined, with every curve just right and nothing out of place. Her skin seemed so smooth and soft, without any blemishes or imperfections anywhere. I felt like an idiot as I stared at her, unable to look away from her flawless figure.

"I don't mind letting you have your fun with her while I'm inside," she said softly. "I want to please you, remember? And maybe I can enjoy it too. I can see her memories. Sex looks like a lot of fun."

I looked back at her, feeling my cock grow hard in my pants.

She smiled and moved closer to me. As she got close enough, I grabbed her by the waist and pulled her into my arms. Our lips met, and we kissed deeply. Her tongue danced around mine, slipping inside my mouth as I held onto her. My hands roamed all over her body. Her nipples hardened under my touch, poking against my fingers.

I broke the kiss after a few minutes.

She had closed her eyes, breathing heavily.

"Oh god, Simon, it feels so fucking good!" She whispered in my ear. "You're a better kisser than my boyfriend."

"Your what?! " I exclaimed.

"Oh, right..." she giggled. "I never told anyone, but I'm dating a guy, Kevin."

I froze.

"Kevin?" I repeated, confused.

"He's such a lovely guy... I love him," she said with a deep sigh.

Who was talking? Again, the slug seemed to have merged entirely with Jenny.

Suddenly, her expression became much sterner.

"But I can make her forget all about him if you want," she added. "And I can make her lust after you like a dog in heat."

Suddenly, she moaned as her eyes filled with desire.

"I can make her so fucking horny for you!" She cried, rubbing herself on my leg. "Please! I need to cum! Please! I'll do anything you say! Just fuck me, Simon! Fuck me! FUCK ME!" She screamed.

She grabbed my hands and placed them on her huge tits. I squeezed her firm flesh, my fingers sinking between her large, perky breasts.

"Simon! Oh fuck!" She groaned loudly.

She turned around, presenting her ass to me. She wiggled it, inviting my attention.

"This is so fucked up!" I whispered to myself.

I couldn't believe my step-sister was acting like this. She was behaving like a whore, her brain taken over by the slug, but the temptation was too strong. I pulled my pants down, moved behind her, and grabbed her hips.

I pushed forward, and she let out a long moan as I entered her from behind. I started moving slowly, enjoying the feel of her tight pussy. She was so wet her juices were dripping on her legs.

She was moaning continuously, her head thrown back. I started to move faster, making her scream.

"Oh my god, this is so good! So fucking good!" She yelled. "Her brain is on fire! I'm gonna come!"

I could hear her screaming louder and harder, her body tensing up. I kept thrusting, feeling her cunt spasm around my dick.

I kept going for a while, completely lost in the feeling of my cock buried inside her.

"Fuck! I'm coming! I'm cuuuummiiiinnnnngggg," she squealed after a moment.

Right as she did, I felt myself filling her, exploding inside her.

I leaned back, pulling out of her, panting and exhausted.

"That was amazing," I said.

She looked at me, smiling, her eyes half closed.

We both sat there, breathing hard for a moment.

I could not believe what I had just done. I had fucked my own possessed sister. I had fucked a slug in a Jenny's meat costume.

Or did I? Wasn't Jenny the one doing the thinking, feeling it all?

"I'm so confused right now," I said.

"Yeah," she replied. "I'd figured you'd be, bro. I'm confused, too."

"There is no way in hell Jenny would have fucked me like that," I said.

"Well, it's true," she said. "But at the same time, she just did. I just did. Honestly, I'm more Jenny than I am the slug. I can't..."

"Yeah, yeah..." I interrupted her. "You can't do the thinking. I heard you the first couple of times. But you're the one pulling the strings."

She sighed.

"I guess you're right. She's my puppet," she admitted. "But looking at a human brain from the inside, I'd say you all seem to be puppets."

"What?" I asked, feeling a sudden chill.

"Simon, I can see what neurons fire for every single one of Jenny's thoughts. It's all right here in front of me. I can predict which ones will be triggered and when or why. She's as much the puppet of her own brain and environment that she's mine."

"Ah, yes!" I exclaimed, biting my tongue. "No free will for us poor humans."

"If there is any, I don't see it," she said, shrugging.

"So what?" I asked. "That makes it okay for you to do whatever you want to her?"

She looked lost in her thoughts for a while, playing with her hair exactly the way Jenny would.

"I haven't exactly been happy lately, you know," she whispered with a sad smile. "I... I mean, Jenny hasn't... Sorry."

"Let me guess! This is when you tell me you can make her happy, right?"

"Yup," she nodded. "I can rewire her. I just did. I made her lust after you like no girl ever could, and she did. And I did, through her. I can also rewire her brain for her to be happy."

"A happy little ****?"

"If that's what you want, you pervert," she replied, winking at me. "Or just happy, and I leave her alone forever."

"And what about you? What do you want?"

"I want to please you," she said. "Desperately, for some reason. It's my purpose. If I can enjoy myself, that's even better. I don't wanna go back to being a stupid slug. But I will if that's what you want."

"I need to think about it," I said.

She smiled and stood up.

"Time to get back to the jar then!" She exclaimed. "I think I need to rest anyway. That was quite intense."

I nodded, grabbing the jar from the floor beside my sister's bed.

"Before I leave her brain alone. What should I do with her?" she asked.

"What do you mean?"

"Should I make her forget everything? Make her think it's normal for you and her to be naked in her room in the middle of the night? Should she still do everything you tell her to? Should I make her happy? Should I..."

"I get it! I get it!" I interrupted her. "Just let me think this through, okay?"

"Sure," she said, crossing her arms and squeezing her huge tits in the process. "Take your time."

I rubbed my temples, trying to calm down.

I looked at my sister's face, and I forgot who was in control for a second. I just saw Jenny naked, looking at me with her usual smirk.

I shook my head.

"What can you do?" I asked.

"What can't I do?" she replied, giggling. "I could make her believe she's the Queen of England if that's what you want."

I chuckled before shaking my head.

The moral thing to do was to have the slug return Jenny back to normal, tell her the truth about what happened to her, and figure out what to do with that supernatural creature that could take over people's brains.

But that would mean giving up on the craziest opportunity of my life. I could turn my sister into whatever I wanted. Maybe I could do it with other women, too.

A series of faces flashed in my mind: sexy girls I knew. I imagined them all nude, begging me to fuck them. I could feel my cock hardening again.

No, there was no way I could take any decision right now. This was too hard.

"Could you make her think we fucked because I asked her to and that it's perfectly normal?" I asked.

"Sure! I mean, she would have fucked you anyway if you had asked," she replied. "Should I keep her incredibly attracted to you?"

"No... Just thinking it's normal, we fucked will be enough for now. We'll see about the rest later on."

"Alright!"

"Oh, and maybe make her ignore the slug... I mean you?" I asked.

"Done!" She said.

I nodded, and she dropped ****, her tits bouncing as she fell on the bed.

The slug got out of her ear, moving slowly. Again, its glow had diminished.

I quickly grabbed the jar and put it in.

"Simon?" I heard my step-sister call.

"Yes?" I replied, on edge, waiting to see exactly how she would react. After all, I was butt naked in her bedroom in the middle of the night, and she had my cum dripping from her wet cunt.

"If you're done using me like your acting-whore, I'd like to sleep now," she said.

"Yeah, yeah," I answered, relieved. "I'm leaving."

"Thanks, bro."

I was about to open her bedroom door when I turned around and asked.

"Does it bother you that I fucked you?"

She frowned and turned around on the bed, pushing her face against her pillow.

"Jeez, Simon, do you really need to be reassured constantly like a baby?" she groaned. "You might be surprised to hear you're not the center of my life."

"So it doesn't bother you?"

"No, it doesn't bother me. Jeez!" She exclaimed, throwing a stuffed animal at me. "It's just sex. Why do you have to make it awkward? Just let me sleep!"

But I really needed to understand what was going on inside her mind.

"It's ****," I insisted.

"Ghaaa!" she grunted, frustrated that I wasn't leaving. "We're not blood-related, stupid."

"And you don't find it odd that all of a sudden you're sucking my dick and letting me fuck you?"

"You fucking asked! It's not my fault you are a perverted creepy dork!"

"But why are you agreeing to do it?"

She leaned on her elbows and looked at me, sighing.

"Honestly, Simon, if you are going to be that annoying every time you ask me for a favor, I'm never gonna do it again. Good night!"

And with that, she turned the light off.

I looked at the slug glowing faintly between my hands and left, closing the door behind me.
