The next few weeks went by without problems. I spend most of my time inside my pocked dimension, creating all kind of things.
I had some time to think and realized that I might have gone a little too far with Tonks. I didn´t see myself as truly evil, I was just a terrible combination of a sociopath, sadist and teenager. That didn´t mean I was going to stop of course, just that I was limiting it to the first of each month so that she can be prepared herself. I was also going to give her presents as compensation each time, well it´s more like I was using her as a test subject for new potions and artifacts but that wasn´t much of a difference.
I was currently sitting on a coach inside my lab, watching the Quidditch game through one of my screens. It wasn´t a very interesting game and the sport had many loopholes but I watched it because this was Harrys game against Slytherin and you never know what the movies and books left out that could be interesting.
Long story short, they didn´t. It truly was just what was shown in the movie, a game of chase and dodgeball on brooms that would only stop when the someone caught the golden snitch. I was actually tempted to just steal the snitch during a game just to see how long they were going to play for.
It was now October the first and you know what that means. Tonks has already recovered almost completely and the only signs of what happened were her being more vigilant of her surroundings and leaving her friends very rarely. I occasionally teased her with a few zaps in public but other than that, nothing. So, you can imagine her fright when I woke her up in the morning with zaps until she came.
She spent the rest of the day close to her friends while always looking around. She was now on her way back to her common room from class with her friends and it was time to play again. I gave her friends suggestion to go to the bath and take her with them. I followed them and made sure to decrease the brightness and temperature in the surroundings again.
She noticed these changes immediately and started to panic. Her friends just continued, not caring for her mental state. When they were all on the toilet with exception of Tonks, who was standing with her back to the wall and facing the entrance, I came through the door in my shadowy form.
I saw her hair go back to white ''Help!'' she knew what was going to come so she screamed to her friends, only to not get an answer back. I had obviously already put spells up to prevent us from being discovered. When she noticed the lack of response she just gritted her teeth, took a step forward and looked me straight into the eyes. ''Do your worst. I swear I will make you regret it one day'' where did she get that courage from, but I gotta say, I like that fire in her.
I pushed her against the wall with her back to me again but this time she resisted a lot less than I expected. What's going on? I just shrugged it off, she was wearing normal clothes like most upper classmen did, so I just tore open her pantyhose, lifted her skirt, made her bend over and stick her ass out.
Hm? Looks like she learned a bit from last round and way a bit moist. I didn´t hesitate and just put it in. I could her some groans from her and knew that she was feeling at least some pleasure this time.
I could enjoy her inside and the ripples on her ass for a few minutes before I was coming close to an orgasm. It seemed she noticed this and took this opportunity to do something I didn´t expect, she grew thorns inside her cave, piercing my dick from all directions while I came inside her.
I could see the victorious grin on her face even from behind. I looked like she prepared but why was I enjoying this pain a lot more than I though. Was it because I was climaxing and feeling pain at the same time or was I a masochist deep down as well? That needs some research but thanks to her I learned something new about myself.
''How do you like that? It hurts, right?'' she looked at me with an exhausted grin. For the first time in years, I gave a sound from me ''Hahaha, this fire in you is exactly the reason why I chose you'' I used a spell to change my voice to be deeper of course ''let me give some presents to you'' she looked completely shell-shocked that I was not only talking to her but also laughing in this situation.
With my dick still penetrating her and being penetrated by her, I put my hand under her bra and pulled on her piercings and activated the electric enchantment, I enjoyed how her inside was twitching.
But that wasn´t my present of course, I added several new enchantments to her accessors like mental shield, magic protection and fertility control, and connected the enchantments to her mind so she instantly knew what I did. I also gave her some control over the pain and electricity enchantment so that she could play a little with herself.
I could see that my actions obviously confused her 'You will get more goodies in the future if you entertain me.'' That shut her up, somehow things weren´t going how she thought they would.
I took out a potion and chugged it down. My dick immediately went back to its final form and I just used my NE to harden it and pulled it out, breaking many of the thorns in the process. I didn´t give her to think and aligned my dick with her back entrance.
''wai-'' was all she could say before I shoved my whole dick inside. This felt different but nice. As I was enjoying myself, I decided to let her have some pleasure as well and activated, not the electric enchantment but the pain one. Her reaction was instant as she screamed in both pain and pleasure.
Ah, yes, this was perfect. Let´s enjoy it even more. With a thought, I deactivated the spell around us that prevented her from hearing her friends. Her face was priceless when she heard their voices just a few meters away from where she was being fucked and she instantly got even tighter.
Under suck stimulation, I didn´t last long and came inside her, she didn´t fare any better and was now a twitching mess. Satisfied, I pulled out and enjoyed the pop and view of my cum flowing out of her two holes. ''Get ready, your friends will be done in five minutes'' I told her, I wasn´t so heartless to let her be seen like this by others. As walked out again I told her ''Until next month. I will have a present that you will like very much''
******
A/N- She will slowly get used to it, at some point I plan to even give her the Stockholm syndrome. I belief knowing that you will feel both pain and pleasure one time every month will make you count days to that day and at some paint this will turn from fear of this day to anticipation.
