Manami POV 

"I thought you liked brother since you were always around him," I said.

Emi still had her arm around my neck as she licked her lips. No rather I'm disturbed that your pushing me against the restroom door. Actually did I just hear a click sound, wait a moment I looked down shocked to see her have the keys to the door. 

"Wait did you switch the door lock, I know your good with technologies and stuff but when did you switch the lock to the key," I asked.

I'm disturbed she went as far as to do this to me. I mean there's no warnings at all if I go by my memories. She'd always be hiding behind Kasumi when we were kids.

"Don't worry it's a double sided lock that only if you had the key can you open it," she said.

Her pale white skin flushed a deep red as she blushed. Actually this is a problem I'm trying to head to class.

"No worries I had called Kasumi to inform the principal that I took you," Emi said.

This is rather awkward since she had me pinned to the door in a way. I can try getting the key but that'd hurt her. It's also akward cause I know Emi is brother's childhood friend. Back then I thought she liked brother too. I guessing that was just her cover for her emotions now.

"What are you thinking," she asked. 

No rather stop distracting me with your hands. She, no longer had her arms around my neck. I'm shocked at the fact that she unbuttoned my white shirt so fast and she's now groping my chest. As she squeezed me hard I let out a pained moan. Wait is she a sadist because she just gave me a eerie smile. 

Her hand quickly unfasten my bra, I quickly try to cover them. To my surprise she did something to my arms making them freeze in place where she wants them. Are you even human, I wanted to ask. Emi licked my nipples and sucked in me hard making me moan against my will. I tried to deny this is the Emi that I knew so well. 

"I found out from Ren why he's here and what happened to you during your middle school year. I'll do this to help you figure out whether you love it or not."

Hold up, your not even giving me a chance. My eyes widen in shock as she took off my skirt and underwear off. No rather I'm disturbed now that I noticed my arms is being held down by a robot. It's disturbing I didn't even see him there.

"Aren't you lucky Mana you get to be tested by my first prototype's strength. Also don't break him with your inhuman strength be a good girl and let me do as I please," Emi said. 

I couldn't even cover my moan as I moaned as she spread my legs. Her hand gently fingering me slightly, a evil grin on her face as she opened my legs to the fullest she could. Instead of holding it in place she asked her robot to use his second set of arms. Wait so he had four arms and he had stealth mode. You cheat, I so wanted to shout at her but I blushed as she pulled her finger back. 

"Aww your still a virgin here though your no longer a virgin vampire. But no matter I'll be your first. Be glad I haven't broken your hymen yet. Oh how I'll have fun with you teasing you until you want me to. Don't worry I won't break it until you beg me," Emi said sweetly.

Actually you already ruined my image of sweet and innocent Emi I once knew. Emi went in between my legs and started licking. Her tongue was twisting my inside but it stayed just outside my hymen. She kept at it for hours my legs were dripping wet from sweat and her head being in between my legs I was being at her mercy. I finally asked her to get it over with, a smile went across her face and I felt a chill go down my spine. 

I had a feeling she had already planned for this since long ago. She stuck two fingers into me and twisted my insides as she fingered me gently. My head was going blank, it's my first time yet it didn't hurt much, it did sting a bit but she was so gentle that it felt weird. 

"Ah, please, Ahhn no stop it," I pleaded.

"But look your waist are moving on it's own even without my robot you hold your legs anymore. Also seems like, your eyes are misty and moist." 

3rd POV 

Manami tried to deny it and shook her head but Emi smiled as she moved her hands way from Manami. 

"Then I'll stop," Emi teased.

"No (gasps for breath) I haven't even climaxed, (moans) stop the teasing and give it to me."

"Aww she gave up and asked for it," Emi singed. 

Her amused look as she held the pink string vibrator in her hand, a smile crossed her face as she laughed. 

"Then I shall happily make you climax. But not with my hands. Instead I'll test out my tuned up vibrator I personally created for this. Ah don't ask also I already tested the sensitivity using Ren. This is version 13. He couldn't think straight with this thing in his ass."

Manami looked at her frightened as she regained her senses. 

"How cute your trying to resist. Also your brother is my broken toy from this don't worry, this will take you to a whole, new world," Emi said. 

Her hand went to Manami's pussy as she pushed the small pink vibrator inside. Her hand went to the remote in her left hand as she licked her right hand full of Manami's juice. 

"Oh so lovely your stubborn expression of not wanting to give in to the pleasure. This little thing has three modes to it, first one increases your sensitivity, second it has a gravity function, third it ravages you nonstop. Another thing it's fueled with mana particles or magic so it's pretty much using your mana against you and also takes from the surroundings you don't even need to charge it. I'm sure you'll love it."

Manami didn't talk, she drooled as Emi turned on the gravity functioned. She ordered her robot to let go of Manami. Her lips went to lick Manami's nipples and a loud moan resounded even in the hall ways. 

"Looks like she fainted. I shouldn't have put the gravity on 25 G, guess she couldn't handle it. Ren call handle 239 G. Then again that was me training the vibrator to be used on Manami. Oh this'll be fun, Manami we still got 4 years to develop you," Emi sighed. 

Emi pinched Manami's nipples. 

"Your not wrong to think I'm a sadistic person. But there's no escaping since Ren sold you out. Also your phone and tablet is so easy to track and use to listen in on you even if you don't use them. Ha as if I'd marry you're brother, are you dense or stupid. Even as a child I gave you the go and you didn't even notice it. So now I'll do the chasing. There's the fact that you said I'm not like how I thought. Don't worry I have mind reading skills. Not that you'll ever know my ability. I bet you'll love that gravity vibrator as I called it. Oh I'll leave it in you and the remote too since I got the second remote. Longest your around any technology your other my watch no matter where you escape to. I've waited too long. Since the first time I met you at the Ayame residence. I was just 7 then you were just 4, oh seeing you cry and hiding from Kasumi back then."

Kasumi came as Emi called her over to send Manami back to her dorm. "Emi your insane," Kasumi growled.

"Ah but I'm just a normal typical stalker that can use any technology and mind reading to my use. I'm just your typical person really," Emi pleaded.

"Your robot in stealth mode won't be able to hide from me. You also said you won't go for her, just what is wrong with you this time," Kasumi shouted.

"Oh nothing at all," Emi grinned.

"You weren't like this in middle school," Kasumi countered.

"Says the one that can't even confess to Ren. By the way keep away from my toy and the sister," Emi warned.
