Y/n is at the party held by Kalim, he invited almost everyone that are close to him, even teachers come, like Crowley, for example. Kalim is always into such things, he loves having fun as well as seeing others being fun. Literally, everyone was chilling with their friends, Y/n has Grim, Ace and Deuce, the head of the dorms also befriended with her lately, which makes her school life even easier than it was.
  From afar, the one and only alchemy teacher, Divus Crewel was watching Y/n from the very beginning of the party. Why, you ask? Simply because he has a thing for his little puppy, Y/n L/n. Aside from her good personality as a student, she's also a good looking one that left him such nice impression. She's one of those rare girls that caught his attention, obviously, she got everyone's attention because how kind she was towards them, but Divus wanted her to be his alone, his puppy shall not be bothered by others. That is why he's trying to find a way, a good reason to get closer to her, not too suspicious, enough to get her to stay with him. He waited and waited until everyone left the lounge one by one, Grim also fell asleep, which is what Divus expected, and there was Y/n, alone and all by herself. Divus, acted as a good teacher approaching his beloved student with a glass of wine in his hand.

Divus: Isn't it time for bed, puppy?

Y/n: Crewel-sensei!! Ah, it is..

Divus: Well, mind if I escort you to bed? You don't seem that fine from all those drinks you've had.

Y/n: I'm thankful, as long as you're not bothered by me, sensei.

Divus: Leave that friend of you be, he's in a sweet dream, I think, don't wake him up.

   Y/n nodded as Divus leads the way, they talked about many things on their way to Scarabia's guest room. They were standing in front of the door and Y/n was about to say goodbye to him.
     'It's now or never' Divus thought as he secretly drank the small bottle of aphrodisiac. Who would've been this insane just to be in a relationship with their crush, Divus would. He did it as he has planned since no one is as foolish to make him drink this and he's not that stupid to put something like this into his student's drink, who knows the consequences. The best way is to drink it himself. Seems like the potion started to kick in, Divus isn't feeling well at the moment, his body is heating up. Noticing the changes of the expression on his face, Y/n stopped to check him up, he can barely stand on his feet so she had to give him a hand.

Y/n: Sensei? How about you stay in my room for awhile before getting back to your room? We're close.

Divus: Guess I have no choice... Sorry for bothering you.

  Under the mask of a poor man that needs help, Divus was smiling from deep down, his plan is working so well that he could see the perturbation on her face, such fine view. The moment the door closed behind their back, Divus took action, he took off his furry coat and put it aside.

Y/n: S-sensei? 

Divus: Shush, puppy.

    Divus pushed Y/n onto her bed while he slammed his lips onto hers. Being kissed so sudden leaves Y/n no chance to resist.

Divus: Stay like this for a while..

  Y/n could feel that there's something touching her from below. His tongue wrapped around Y/n's, it kept twirling, Divus feels like he's been freed for after a long time suffering of waiting for this day. His hands find its way to Y/n breast, the girl was too weak to push them away. Not to mention, those actions really drives her crazy, she couldn't think of a day when she'll be in such situation with the teacher whom she respects the most.

Y/n: Mhmm.. Don't, this is wrong, sensei...

Divus: Shh.. You're my puppy. All you have to do is to obey me.

  Y/n's eyes tear up, no one ever treated her like this before. Seeing that makes Crewel feels bad, but not enough to stop him making her finally his own, so he covered her eyes with one hand while the other is toying with her nipple.

Divus: You will start to like this in no time. Y/n, you'll have to beg me for this.

  His hand stopped, leaving Y/n breathing heavily. But that is not all, he flipped Y/n back as her back is now facing him.

Divus: Get up on your legs, lift your hips a bit higher.

  Y/n was forced to do so, otherwise she'd be shouted at. Y/n knows his personality well through his classes, he's strict, everything has to follow his instruction, going against him is like a death wish. Without any warning, a hot thing suddenly slid in between her thighs. Though she already knows what that is, Y/n couldn't do anything, at least he's not putting it inside her. Crewel moves his hip faster, the thing down there also hardened, he finally reached his limit, as he pulled it out before Y/n got dirty.

Divus: Next, you have to clean it for me.
