#dark!pero

Pero knew he wanted you after the first day of class. You sat in the front, raising your hand for every question, so smart, but so innocent. A goodie goodie as mean students in class would whisper behind your back. He punished them the most with bad grades.

While most students were afraid of him because he was an ex auror and was littered with scars, you were curious. You stayed behind class to asked him questions and listen to his stories. Pero had no problem giving you preferential treatment because he loved the blush it would produce. Whenever he called your name or asked you to come to the front of the class to explain, you would give him the biggest smile and he would feel his cock harden under his robes. He wanted to tell you what a good girl you were being.

You asked for extra readings to get ahead. As his lust grew he started giving you more and more perverse books to corrupt your mind. Books on dark magic, lust potions, mind control, and breeding potions. If you noticed, you didn't say a word.

He started sneaking into your dormitory to watch you sleep. He liked seeing your smooth skin in the moonlight and your curves free of the baggy school robes. He would go back to his room later and jerk himself until he came, wishing you were with him. The fact student and professor relationships were forbidden only made it more exciting. You were such a good student, he wanted to make you break a rule.

Today's lesson was on love potions. A very tricky potion to make. He usually hated this day because when students would fuck up the side effects were disastrous. The potion was supposed to induce affection but if done wrong it could result in obsession, lust, or even death. However, now that you were in the class Pero felt more excited. He had entertained the idea of slipping you a love potion on many occasions. It would be so easy because you trusted him already. He finally formed a plan to give one to you through the ruse of this assignment.

He paired students up and purposefully left you out. He didn't want to risk some other idiot student poisoning you and he certainly wouldn't sit by and watch you fawn over someone else.

"Are you okay to work alone, hermosa?" His gruff voice sent a thrill down your spine.

"I promise not to poison you, sir." You teased.

Everyone started brewing, turning the burners on and making the room heat up. Every time Pero would walk by your work station and grunt in approval you felt yourself get a little wetter. His approval and small bits of praise were everything to you.

The smell of the potion, supposed to smell like what attracted you, filled your nose. Leather. Tobacco. Brown Sugar. Professor Tovar. You inhaled the scent greedily not even realizing what you were doing. You unbuttoned your shirt a couple of buttons down, rubbing your neck sensually. You were the best student in here but you were becoming distracted by him. Without realizing it you missed a step.

"Wrong. Entirely wrong." You heard Pero scolding a pair of students whose potion made their voices switch rather than produce any affection. "Fucking idiots. Remediation is next week."

Another couple of students were making out loudly behind you. Pero pulled them apart, cursing when he saw the color of their potion.

"You stirred it too much. You made a lust potion." You looked over your shoulder to see him towering over the two students, casting a spell over the potion to trap the smell.

"Professor..." The female student tried to throw her arms around him seductively. You felt yourself glower. You didn't like that one bit. Thankfully, Pero threw her off.

"Both of you get up to the infirmary. Rollands you go with them make sure they get there. The trio stumbled out, the pair already trying to strip the robe off Rollands. Poor guy.

The room was empty now. Pero felt his heart quicken in excitement. He shut the door, turning the lock. He could smell honey suckle and vanilla; your scent.

"How are you doing over here, querida?" He asked.

"F-fine. I think I'm done, professor." You fan yourself, watching him lean over your cauldron and take a long inhale.

"Smells delicious. I'll need to taste it before I give you your grade?" He purred.

"Do you- you need my hair?" You tried to remember what the last steps were. If you were trying to give someone the potion, all you had to do what put a single strand of your hair in.

"Yes." Pero lied. He had something else in mind. He took your cauldron to his desk and with his back to you, he poured it into a glass and put his own hair in. He poured another glass of water for himself. He planned to give you the love potion while he drank water.

"Water, querida?" He turned with both glasses in his hands only to his surprise you were stripping off your shirt and bra. "What are you doing?!"

"I'm sorry. I'm so hot. Something's wrong..." You looked away in shame, tugging at your skirt now. Your perfect tits made Pero's mouth water and his cock harden.

Pero sniffed your potion again, which had turned a bright red from the clear it was previously. The smell was much stronger. The slight metallic undertone only confirmed it. You had made a lust potion. A quite potent one at that. Just smelling seemed to have affected you. And now Pero felt the effects starting to invade him as well.

"Oh querida..." Pero purred. His mouth curl into a toothy grin. Maybe a part of your mind made the mistake on purpose so he would fuck you. All those dirty books he had given you inspiring your darkest fantasies.

"What's wrong with me... I feel...oh god." You clutched your stomach bending over the desk. Your tits hung down, teasing him. Your hips rocked in the air trying to get some sort of relief. Your core was aching like you had been edging yourself for hours. Your stomach was cramping painfully. "I need to go to the infirmary."

"No querida... I'm afraid they won't be able to help you." Pero lied, liking the change in plans. "But I might."

"Please-please help me!" You begged. Looking at him you imagined sinking your nails into his broad shoulders, bouncing on his cock. God... where were these thoughts coming from.

"Come sit down." Pero faked concern as he helped you into his large arm chair. His rough touch against your arm made you moan. Pero ate up the fearful desperate look in your eye. You were so innocent and pure but your body revealed how much of a dirty girl you really were.

"Mmm...it hurts!" You turned your head into the cushion inhaling more of his scent. "Is there an-an antidote or a spell?"

"No I am afraid not." Another lie. "Let me see, querida. Where does it hurt?"

You spread your legs, pulling the hem of your skirt up to your stomach. "Here! Fuck I'm sorry professor. I'm so-please!"

"Shhh shhh. Let me." Pero ran his finger through your soaking folds, pulsing with blood.

"That-" You felt some of the ache subside, turning into pleasure at his touch. "That felt better. It's better when you touch down there."

Pero's cock twitched at your innocence. Little you didn't even know what to ask for.

"When I touch your pussy?"

You nodded, blushing and not from the potion.

"Like this." He repeated the motion with more force, sliding his finger into you pussy. It was so tight he had to pump it back and forth until you accepted it.

"Yes-oh yes..." You sighed feeling some more of the pressure subside. A new feeling taking its place. "No wait!" You grabbed his wrist when he started withdrawing.

"You want me to keep going?"

"Yes. Please... it feels good." You tried to pull his hand back to your core.

Pero growled deep from his chest, kneeling down now. He latched onto your clit making you squeal, digging your nails into the arms of the chair. He fucked your pussy with two fingers, trying to get you to open up. Your taste was sweeter than he ever imagined.

"Think, querida." He looked up, his lips wet with you. "Use that smart little brain. Where did you go wrong? What is the antidote." he quizzed you like he did in your class. You wracked your lust ridden brain trying to think of what this potion could be. What step did you miss?

"Professor!" You ground yourself against his hand, throwing your head back against the chair. "I know-I know what I did! The antidote- it's your cum. I need your cum inside of me."

"Good girl. I knew you knew the answer." He paused again, watching you squirm under the praise. "But a professor and a student... it's forbidden." Pero pretended to be conflicted even though he was more than willing to pump you full of his seed.

"But-professor Tovar I need it. Please. I won't tell anyone."

"If I fuck you..." He grabbed your face, curing his fingers inside of you. "You'll be mine forever. This will be the beginning, not the end. You understand?"

Your eyes widened at the statement. You were burning up. You needed the antidote or you would die but at what cost? His dark hungry eyes were unlike anything you had ever seen before but it stoked the arousal you felt.

"Please, professor. Please I don't care. I'll do whatever you want!" You feel tears spilling out of your eyes at the pain from the potion.

"I hoped you would say that... my innocent little girl. Well... not so innocent to be begging for my cock."

"Please!" Your voice jumped up due to the pain.

"Call me, Pero."

You breathed harshly as he stripped off his robe then his shirt and pants. He was so broad and thick. His muscles were toned, highlighting scars from battle. And his cock stood proudly between his legs, resisting gravity with its strength. You spread your legs wider in anticipation.

He kissed you then, forcing your mouth to take his tongue, previewing the way he would fuck you by harshly licking and biting your mouth. Before you could even take another breath he thrust into you without mercy. It was hardly any resistance at all. That pain in your gut subsided enough so you could think straight. What had you just agreed to? Did it matter when it felt so good? Pero was grunting above you, holding your thighs apart. You felt a small tinge of pride at the fact you made him feel good. You were always eager to please. Your skin smacked against his and your pussy squelched in a positively sinful symphony of sound. You prayed no one would hear you moaning.

"I'm-oh god-Pero!" You felt something tightening in your stomach. An orgasm? You had read about them but never experienced one. "Wait, professor, I think-" Your hand flew to Pero's hip. But he didn't stop, in fact he sped up. His cock was brushing against your cervix and soon his seed would take root there, the antidote you needed. His head was tilted back, a sick smile on his face as he took you over and over. He was your favorite teacher and now he was teaching you what pleasure was. You erupted in flames and vaguely you were aware of Pero's dark laughter as he watched you cum.

"Feel better?" He smirked down at you.

"Yes... thank you-oh shit..." You felt the harsh pain in your core come back with a vengeance. "It hurts again!" He lifted you off the chair, his cock momentarily falling out of your pussy. "Please-"

Pero lifted you and set you down on his desk, pushing your back down against the papers. He thrust back into you. You felt immediate relief, hugging him towards you with your legs. You needed his cum more than ever. Pero cursed, your walls even wetter after your orgasm. He wasn't going to last long. Not when he had been dreaming about claiming you for months.

"Mine... mine..." You realized what he was growling under his breath. "Oh querida." He grinned at you, his rhythm faltering, "I'm never going to stop fucking you. Even when you sleep- you're gonna dream of me fucking you."

"P-Pero! Oh god!" Your toes tightened. You knew it was true. The feeling of his thick cock in you would not be forgotten.

"Are you ready? Are you ready to be mine?" He leaned over you, squeezing your tits in his hand.

"Yes!" You nodded feeling the potion continuing to make your pussy ache and burn.

"Such a good little girl. All mine." He brought a hand down to your clit making you cum with him. "Mine!" He growled feeling cum shoot out of his flared head. He pulled his hips flush with you, feeling each pump cement his ownership of you. He had finally gotten everything he ever wanted. There would be no going back.
