Mentoring
This is a little smut fic I wrote for Diavolo's birthday, but since I have two fics now and this isn't a "birthday-themed fic," I thought I'd post it now.
CW: MC is AFAB and nameless, uses she/her pronouns. Piv sex, creampie, roughness, harsh language.
WARNING: This fic is centered around the CNC kink. I will explain what that is, but if it's something you may not enjoy due to trauma or other issues, please don't read!!!
CNC: Means consensual-nonconsent. The premise of a cnc scene is that beforehand, both partners agree to certain types of rough or aggressive sex that is of "nonconsesual" nature during the scene. The consensual part is the agreement before the actual sex occurs, where safewords, boundaries, and other parameters are in place. Some people call it rape play, I don't necessarily agree with using that as a blanket term for CNC. This is risky and should not be taken lightly, just like BDSM.

"So we are in agreement. We're doing this?"
"Yes... I think so."
"You can't just think so. This is something that could go poorly for both of us if we aren't both on board with it."
She was quiet for a moment, deciding what to say next. Diavolo lifted her chin and gazed into her eyes, a softened but serious look in his.
"I want this. We have our rules, we agreed to the rules, and we know our way out should we need it," she answered confidently.
"Then... so it shall be."
She sighed as she gazed at her test score. It was fine, but she wanted better. Quietly, she folded it and set it aside so she could focus on class. That was, until she saw Diavolo walk in, making a beeline for the teacher's podium.
"Good morning everyone. Your professor had to take leave today, so I will be filling in for the day. His message to you all is to work on your assignments due this week. You may ask me questions if you need to. No lesson for today," Diavolo explained.
The class became quiet and got to work as instructed.
Except her.
She stared up at Diavolo for a solid minute until his eyes finally landed on hers. She raised an eyebrow. The corner of his mouth barely tipped up.
Today was the day.
She began to work on her homework for the next hour, counting the minutes and seconds until class was over. It was so much more distracting to have him there, just steps away from her own desk while he sat at the professor's. The anticipation was building, and all she could do was organize in her head how this would go. Her thoughts were consumed with running each scenario, every word, every single movement they could make. It was so important that this went right, and maybe–
"And that's class. Thank you all for coming. Have a good day," Diavolo announced, standing at the podium. Everyone was already up and leaving, having packed their things while she just sat there daydreaming.
Once the room was cleared out, she cleared her throat quietly and got up from her desk, her test in hand as she walked up to the podium.
"Hey, I had a question," she stated confidently but softly, trying not to intrude. She saw the papers on his podium and knew he was likely busy.
"Yes, what is it?" He replied in his usual candor, golden eyes gleaming and bright white smile beaming.
"I got this score on my test, and I really thought I did better... Is there any way I could... get some help?" She answered, handing him the sheet of paper. He looked over his nose at her and nodded, taking the paper and setting it down to look at.
"I'll see what I can find."
He scanned it over, reading every question and answer. If there was any skill he mastered, it was looking at anything unfazed and replying in a similarly unaffected manner.
"I see. So, you seemed to have not totally understood this concept here, and this one could have been better here," he explained, pointing out to her what he meant. She came closer and nodded, listening carefully. "I think this one could have used a few more examples to drive home your point as well."
She sighed. "Yeah... That's what I thought, too. I wish I'd done better..." she murmured to him.
Her mind became distracted again, thinking about how good he smelled, the amber and musk filling her head with ideas other than this test.
"Are you listening?" He asked quietly, bowing his head to look at her.
"Oh, sorry..." she mumbled.
Finally, she turned her own head up to look at him, and she swallowed thickly at the idea buzzing in her skull, the one making her question every fiber of her moral being.
"Is there... anything I could do to improve my score? Anything at all?" She asked carefully and slowly, bringing herself closer and peering up at him with slightly widened eyes, her expression maybe a little innocent.
"Did you have something in mind?" Diavolo asked in reply, his voice pitching lower in his tenor range smoothly.
She mentally took a deep breath, centering herself. I want this. I want to try this, she thought to herself.
"I mean... What are my options?" She asked, her own voice stepping just a hair lower in pitch as well, leaning into the intensity of the moment. Her body moved closer intentionally, now just mere inches away from his.
"Don't be coy, I think you and I both know what you're implying," he answered, a bit dominantly. "I saw how you stared at me all hour. You can't stand here now and tell me you don't know what you're asking."
Here we go.
"Surely I don't know what you mean..." she stated, sounding slightly shocked.
His arm snaked around her waist, and he snatched her closer, a little roughly, and bowed his head down to whisper in her ear.
"Don't lie. You want me to improve your grade in return for something, right? A little mentoring? Well, I know what it is you want, and I know what I want, so why don't we skip the rest and get to the point?"
She nearly trembled then, with excitement and nerves from how he spoke to her so harshly but still yet so seductively.
"I... I don't understand. I just wanted to see–"
"Shut up, and come here," he snapped quietly in her ear, grabbing her by the wrist and pulling her over to the desk. He pushed her against it, wrapping an arm around her when she became off balance from the sudden movements to hold her up. "You asked for it, now I'll make sure you get what you want, and I'll get what I want," he murmured in her ear before biting on the shell of it.
"But–"
"But nothing, now am I going to take these off, or are you going to help?" He interrupted her again, pushing her to sit on the desk and slipping his thick fingers into the belt loops of her slacks with a hard tug.
"No, I really didn't mean–" she tried to insist.
Riiiiiiiiiiiip.
"I guess I'm doing all of the work," he mumbled, quite literally ripping her slacks off with his inhuman strength like the material was paper.
"Dia–"
She started to yelp, but he slapped a hand across her mouth to cover it and keep her quiet.
"Now, are you wanting your classmates to know you want your headmaster to change your grade in exchange for sex?" He challenged her, his gaze piercing her soul. She shook her head. "Then be quiet."
With her torn slacks on the floor in pieces, his hand skimmed up her warm thigh, and he roughly opened it out wide so he could stand between her legs. He looked down and smirked as her underwear peaked out in the creases of her thick thighs and soft tummy.
"You were anticipating this, weren't you? Wearing just a black little lacey thong today. Were you going to ask your professor for this too had he been here?" He mocked her, snapping the band of her panties against her, making her flinch and moving his hand from her mouth. "Answer me," he snapped.
"No, I wasn't asking for this! I–"
She clamped his hand on her mouth again while tutting her. "I said be quiet. Do not yell again unless you want this to get much worse for you," he commanded. She nodded. He smirked at her panicked expression, tears welling up in her eyes. "Now, there's no need for that. I'll give you what you want. Besides, you're going to be good for me, right? This is all for me, and I'll make sure you enjoy it too."
She shook her head, and he ignored her as he slid her panties down her thighs. When she started to fight him, closing up her legs and pulling away, they met the same fate as the slacks. His eyes dilated when he started to see his prize, and instantly got more aggressive.
"Don't. Fight. Me," he barked at her, grabbing both her thighs and throwing them open wider so he could see her perfect little wet pussy on display for him. She still tried to fight against him, pulling away and shaking her head while she whimpered. He sighed and rolled his eyes. Finally, he pinned her down against the desk with his massive hands on her shoulders, papers flying everywhere. "Are you done?"
She stopped for a moment, looking up at him. Her hands had gripped onto his elbows, trying to hang on as he pinned her. She tapped her finger once against his elbow before saying, "Stop! This isn't what I meant at all!" She pleaded with him.
"Oh, but I think deep down it is what you wanted, pet. I think you were waiting for the perfect moment to use your little charms to win me over, but now you have cold feet. You know you want this. Don't worry, I'll take good care of you," he answered menacingly. "I'll make sure you enjoy it, at least a little."
She shook her head and sobbed. Seeing that she wouldn't stop making noises, and he found them to be rather adorable, he snapped his fingers to block sounds within the room from being heard outside.
"What a mess..." he mumbled with a sigh.
He began kissing her on her lips, hoping to shut her up just for a little bit. He ground himself against her body and let his hands wander her body. His fingers made short work of her uniform jacket and blouse, quickly loosening her tie and gaining access to what was beneath it all. He gave a purr of content as he got a glimpse of her. She laid there, still squirming and whimpering, trying to push him off, but that was like pushing on a brick wall when it came to the prince of hell.
"You are beautiful," he murmured in her ear before licking the shell of it a little obscenely. He ducked his head down and left hard kisses, little bites, and trails of his saliva on her chest.
"Stop," she whimpered, turning her head away from him, but he just chased her down with his lips hot on her exposed skin.
He chuckled darkly in her ear and groaned. "I'll even do you a little favor," he told her while he slipped a hand down her exposed form to her pussy. He danced his fingertips along the slit before sliding them past the crevices to reach her clit where he rubbed it generously.
"Noooo..." she groaned, finding it harder to fight against him. "Please don't do that."
"Ohhh, but you're so wet, pet," he murmured to her, and even she couldn't deny how much more slick she became down below. "You're loving this no matter how much you want to deny it."
He trailed his kissed lower and began feasting upon her breasts, sucking and laving his tongue over her perky nipples with elation.
"Finer than any forbidden fruit, sweeter than any sugar," he mumbled against her flesh. "I can't wait anymore."
Diavolo brought his head up to kiss her with his tongue bullying into her mouth. His hands began to unbuckle his belt and send his slacks to his knees. He quickly shed his uniform jacket and loosened his tie.
"You ready, dulcis? I need you," he said huskily in her ear.
Just after he spoke, she felt something warm and hard pressed against her thighs. Pre-cum started to coat her thigh as he rubbed it against her.
"Please don't, please," she pleaded with him, with a tear rolling down her temple.
"Shh, it'll feel good, just enjoy it," he whispered to her.
The demon pried her legs apart again and stood between them, leaning on one hand on the desk while the other grasped his cock to start rubbing the fat head against her little clit.
"Just a perfect little pussy, and all for me," he mused, feeling her slick coating his length. He bowed his head again to murmur in her ear. "Don't fight me. This will go a lot better if you just take it," he warned her before kissing her temple again. All she did was squirm again beneath him.
After pulling his hips back and angling himself, he slid his cock into her, groaning at the overwhelming tightness of her walls.
"Oh god," she whined, trying to worm away from what was bullying its way into her depths.
He chuckled and kept her in place with little effort on his part. "There's no god here to help you now. It's just you and the Demon Lord," he rumbled darkly in her ear.
It took a few more moments for his cock to be fully seated in her. He took the moments after to breathe in her scent, the glistening light sweat on the sides of her neck, and her sweet, sweet arousal. It was fuel for his fire to keep going.
"You're mine. You're all mine, and I'm not letting go," he stated with a malicious chuckle.
The first thrust was rough, and she cried out at how harsh it was. She couldn't help but cling onto him, her little hands gripping the fabric of his shirt along his elbows. He went back to planting a field of dark blooms, hickies and bites galore. With every thrust, he grunted, fighting the urge to completely lose it. Little squeaks and groans fell from her lips as well, signing conjuction with the rattles of the desk.
"Hells, darling, you're going to make me let go too early," he murmured against her neck. "You can't tell me anymore that you didn't want me to fuck you raw on this desk, not with you dripping down your ass and my thighs."
"I didn't," she insisted weakly, knowing she was losing the fight to stop him and now trying to win the fight to make it through to the end.
He grunted again as he made another hard thrust into her. His pre-cum and her wet walls made it such easy glides in and out, but there was something so cute to him about how she squeaked and whined with every pounding he gave her.
Diavolo chuckled again. "Right, and you don't want me to release inside you too, hmm? You don't want to feel me finally fill you up properly, to give you what you've wanted for so long? You wanted to be fucked, and now you're simply getting the best."
"Oh god," she whined again, clutching onto his shirt along his chest.
"God doesn't save whores like you who beg to be filled so deeply," he replied in her ear, his voice much more serene for someone who was doing this.
He kissed her neck and wrapped his arms around her body, trapping her entirely as he made the last few thrusts count. Using the desk as leverage, he leaned forward more to bring her hips up so he could penetrate her deeper. It took all of just mere moments to start moaning and crying with relief as he hit that sweet spot deep inside, and only that many more moments to make her body lock up as the most intense orgasm of her life befell her. The hot sparks of pleasure bloomed from her abdomen and spiraled out to her limbs. The chasm of pleasure was a deep one, and when the Demon Lord felt her walls contract around his cock and pulse, he was pulled down with her into the abyss of carnal bliss. Hot jets of his cum filled her in waves as his hips rocked forward with each one.
When it was over, the pair lay there, heaving and trying to catch their breath. Diavolo was the first to relax and gain his bearings again. He looked down at his human lover, feeling a wave of passion and simultaneous anxiety.
"My love... My love, look at me, please, baby," he cooed to her, stroking her cheeks with his hand.
Her eyes fluttered open. She looked relaxed at peace.
"We're done... Finis," he softly whispered to her, his hand rising up to pet her hair back. She nodded in understanding and let go of her iron grip on his shirt. "Are you okay? Does anything hurt?"
She shook her head and reached up with a trembling hand to touch his cheek next. He smiled and kissed her palm, reaching with his to grasp her hand gently. He bowed his head slightly to prompt her.
"I'm okay. No pain," she finally verbalized it for him.
"That's good. Shall I take you home so you can rest?" He asked her in a throaty murmur. She nodded. Standing upright, he reached for his red uniform coat and wrapped it around her as he pulled her up right. It was already long, and on her, the coat looked like a blanket and kept her decent. He then put himself back in order, slacks up and buckled, and shirt back in place.
He slid his arms beneath her and picked her up effortlessly in a princess carry.
She laid her head against his shoulder and asked him softly, "What about the rest of the day? My classes?"
Diavolo chuckled and shook his head, carrying her out of the door, snapping his fingers to use magic to reorganize the desk they just laid waste to with their fornication. "After that, you deserve some pampering and all the care I can give you." He then bent his head down to whisper to her, "Besides, those are the perks of being the lover of your headmaster, no? I make the rules, I say what goes."
Thanks for reading! I hope you enjoyed.
