Infesting Lara's Brain

"How are you so good at math, Eric? I would be lost without you..."

I smiled.

"I'm not that good. But if I can help I am happy."

"All these letters in these equations...ugh! It makes my brain hurt!"

(Soon you won't have to worry, my dear), I thought.

I ruffled her soft, blonde hair, my fingers sliding through her curls. Lara reacted by wacking my hand off with a cheeky laugh.

"Stop! My gosh! You've ruined my style!"

She fixed it, but I noticed a tuft of hair was on her face. This could be the excuse I needed.

Was I ready? I would lose my dear friend...but gain my best sex toy. She would be ours...fully.

It was late afternoon, after school and a few days before the maths exam. The sun was setting, and everyone must have had something better to do, because we were alone in the school library. I've always loved spending time at the library, especially when it gets dark outside. It's comforting. I checked again if anyone was around. Clear. I took a deep breath. A dream fetish was about to become reality...

"Do you want your hair in a ponytail? It might help to keep the hair out of your face."

She giggled.

"What are you, my mom? I would but I don't have any hair ties."

"I may have something...sometimes I borrow my mum's to use instead of a rubber band. Let me check."

I opened the bag and got the small black box containing the main parasite to go inside her, as well as the backup. Holding it in my hands, I felt as if time had slowed down. I could almost feel their need for warmth. Not much longer, I thought.

I turned around.

"Bingo."

I showed her the box and she laughed.

"I can't believe it! You're so reliable."

There was no way she could know the truth.

I opened my mouth to ask her to turn, but she had already moved to have her back against me, caressing her hair back, ready for me to tend to her.

"Don't worry if it feels weird, it will be over in a second."

"You're so odd Eric. My mum's tied my hair many times, I know what it feels like!"

I opened the box.

The two worms were just barely moving. I knew from my experiments that they were in a hibernating state, waiting patiently. As soon as they would be close to the ear, they would activate.

"This time it's special."

She giggled.

Such a cute giggle.

I stroked her hair gently, caressing it, exposing her neck and ears. I felt something when I touched her. Did she want me to touch her? It didn't matter anymore. My corruption was about to spread to her.

"Well, this time may be different."

I picked up one of the worms, its aqua body and neon green rings began to twist from my body heat. I went to caress her hair and held it near her left ear.

It awoke. The worm sensed her pulsing brain, her centre of thought. It sprang forward, entering her ear canal.

"Hey!!"

She squeaked and jumped up from her seat.

"Not funny! Ouch! What did you do to me?"

She reached for her ear. Her eyes opened wide, her jaw dropped. She felt it again. Yes, it was a worm. Yes, it was borrowing inside of her. But I had more to my plan. My expression was one of worry.

"Lara, are you alright?"

I could see her eyes begin to water, her lips were trembling.

"W-what did you do to me, Eric?"

"What are you talking about?"

"There is something-AH! Something is inside my ear!!"

"I thought I had seen something in your hair. Let's go to the bathrooms, I'll get it off!"

She looked around. Her legs were now trembling too.

"No Eric, no! I can't go out, what if someone sees... sees..."

"Then sit down, I'll get it off!"

Sobbing, she set back down in front of me. How gullible. It was a sad sight, but it was also so erotic...the worm was still half outside her ear, but it was approaching the point of no return. I stroked my erection.

"Please, get it off now! I'm so scared! Oh my god-AH!"

I heard a crunch.

"IT'S GOING INSIDE! OH MY GOD!"

I touched its tail. It caressed me back.

"Relax..."

Then, with the tip of my index, I helped it push in.

"...there."

She shrieked.

At this point, the librarian must have heard something.

"No no no no!! You didn't help!"

"We need to go to the toilet Lara, I'll try with hot water, and I'll call an ambulance."

"No, Eric, no! It's going... I-it's going inside my head! Oh my god! Is it going to eat my brain??"

Yes.

"No. That's sci-fi. It's just a bug. Let's go. Hold onto me."

I helped her up, and she clung to me like a baby. She was mine already.

As I was walking her to the toilet, I kept hearing a slow crunching sound coming from her head, as she sobbed and began to drift.

"Eric...that's the males toilet...I'm a lady..."

"Shhh...relax...we'll just go in it for a moment."

I knew no one would be in, and was pleasantly surprised to see I was right. We entered a bathroom stall and I helped her on the toilet. I then locked up all doors.

Her eyes were drifting inside her head. I wondered how the parasite was changing her.

The worm must have been eating well...

The parasite had already swam through her ear canal and reached her brain. It's new grey matter womb was ready.

"Eric..."

She began to lose her voice. A hum was also coming from her mouth, and she was twisting her legs. The parasite must have touched her amygdala.

"How does it feel?"

"...g-goooodd..."

She began to sob quietly.

"So good...no...but...it's inside me..."

"Yes. The parasite will make your brain it's home."

"No...no...I will die..."

"You will be reborn as it's servant and my toy."

She writhed, without shouting, but instead with a quiet moan.

"It's...eating my brain~"

I unbuttoned my pants.

"It is. It will chew on all that delicious grey matter of yours. All that knowledge, both useful and pointless, all your memories...Then, you will become it's perfect ****."

She giggled.

"I want to be your toy~ I've always liked you, Eric~"

"I know."

Another crunch, and another moan, this time louder, as she arched her back, with her head on the wall of the toilet stall.

"Describe it to me, Lara."

"It's munching on my~ I can feel it~ I'm like it's mummy~"

"I can put more inside you if you want. Or do you want it to lay eggs inside your brain-womb?"

"I want to be their mummy~"

"Maybe we can put them inside all of you, inside your vagina, anus, nostrils, even your breast. You could be the perfect hive."

I began to stroke myself in front of my childhood friend, and she turned to look at me in the eyes.

She began to undress and rushed to fondle her clitoris.

"I want to be their hive~ I want to be your slut, your ****~ I want you to fuck my vagina and my brain even more~"

I heard a squirming sound, then Lara mimicked it. She twisted her body and moaned.

She masturbated quicker, rubbing her two fingers inside her labias. She moaned, suppressing the noise between her lips.

"My baby~ deeper~ deep inside my brainstem~ make it your nest~ Eric, fuck me, Eric~~"

She squirted, as I held my erect, hard member in front of her.
