Gasps were heard in the room. Mary lost 40 milion yen. (Y/N) chuckled and stood up.
"Well, looks like I win" (Y/N) smiled as she stretched "when will you be paying me?" she asked.
"I-I don't have that much" Mary managed to say.
"Oh well, then until you can pay me back, you're going to be my pet" she walked over to Mary and put her finger under the girls chin, forcing her to look up "I'll bring your collar and contract tomorrow, mittens" (Y/N) had an evil smile on, she tucked a lock of hair behind the blondes ear and left.
Mary was shocked and devastated, she slammed her fists on the table as tears started falling down her face. I lost, I fucking lost. What now? I'm a houspet, what am I going to do now? Yumeko walked over to her blonde friend and started comforting her.
"Mary-san it's okay, don't be sad. This gamble was so exciting you should be happy. And look at it that way, you'll get to spend more time with (Y/N), now I'm even more jealous than before" Yumeko said smiling, but it didn't reach her eyes.
"Huh I guess you're right, but still I'm a little scared, you know how (Y/N) can be" Mary calmed down, and started packing her things, getting ready to leave.
Tuesday came and Mary entered the classroom, only to be met with contemptuous gaze of... well basically everyone. She made her way to her desk which was now full of insults. Dumb whore, failure, flat chested bitch. Those were only a few of them, she sighed with resignation and sat down. A couple seconds later some jerk purposely spilled his juice and looked at Mary smirking.
"Oy Mary, be a dear and clean this up for me" he said mockingly. As Mary was getting up to get cleaning supplies she felt a hand on her shoulder stop her.
"I forbid you from taking anyones orders other than my own, do you understand kitten?" (Y/N) said with a somewhat threatening voice, the blonde gulped and nodded sitting back down.
"Hey, not fair, she's a houspet, she has to listen to me!" the boy shouted angrily.
"Wrong" (Y/N) turned to him with a death glare "she's MY houspet and she listens only to me, understood?" she paused waiting for a reply, but got none "now, who did this?" the tall girl motioned to Marys desk. Most students were terrified so they pointed at the boy who tried to order Mary around earlier "hmm, interesting. Apologize."
"I'm not gonna apologize to that lowlife are you crazy?!" (Y/N) had enough. In a matter of seconds (Y/N) had the guy pinned to the wall by his neck, squeezing tightly. She stood there for a minute thinking hmm what should I do to him? Something that will hurt ...badly. When she made up her mind she smirked and threw the boy on the floor, stepping on his chest, he started struggling.
"(Y/N) stop you're going to kill him!" someone said but she didn't know who, she was too focused on those amazing screams of pain coming from the poor guy.
"Don't worry, this isn't my first time, I know what I'm doing" she increased the pressure until she heard a few satisfying cracks. She broke his sternum and a few ribs. "Now apologize" the boy tried to but the pain from his broken breastbone was making it hard to breathe, let alone talk. After a few attempts he chocked out.
"I'm sorry Mary-san, it won't happen again" (Y/N) smiled
"Now Mary, do you accept his apology?" Mary nodded shocked about what is happening right now.
"Lucky you" said the tall girl to the boy "now I want to make some things clear" she turned to the rest of the students "Mary here is MY houspet, my property, which means if any of you do something that upsets her, you're not gonna see the sky again, is that understood?" everyone nodded terrified "you!" she pointed at a random girl "exchange desks with Mary and then bring this bitch to the nursing office" the girl quickly did what was told.
"Why'd you do that?" Mary asked, she was content with what had happened but at the same time she was scared.
"Haven't you listened to a word I said? You're mine, I can't have anyone order you around" Mary blushed "now, here is your contract, when you sign it I'll give you a copy" (Y/N) dropped a stack of papers on Marys new desk. Mary skimmed through the text and wondered for a second. Damn I guess I don't have much of a choice do I? She thought signing the papers
"Great, it's official" (Y/N) smiled "here is your collar, everything is specified in the agreement, you should read it carefully at home" (Y/N) handed the blonde a pink collar with „Meari" written on it, and (Y/N)s contact information on the back. Mary sighed and put it on. "beautiful" (Y/N) said smirking, then she walked away to her desk as the lesson was about to start.
Later Mary sat on her bed and started reading carefully through her contract. It stated when she can take of her collar, what she can and cannot do (the basic dom-sub kinda deal). She sighed and turned off her lights, this is going to be interesting she thought as she drifted to sleep.
