The first time he saw her, in the Student Council Room, the demon was intrigued at how small she looked next to everyone present. However, with passing time, he realised that the size difference didn’t mean you were afraid to stand up for the others even if it meant dying at the hands of her own housemates. To say that it left him intrigued would be an understatement.
It was this realisation that made him notice her more than was necessary for the Prince of the Devildom. The blonde was no longer just an exchange student for him. She was special, someone who didn’t cower in fear when interacting with him even when she knew how easy it was for him to just throw her across the room, to snap her neck and rob her of her short life. Once he joked about it when he had called her over at the castle for tea. Her words back then had left him entirely speechless.
“I trust you. Maybe I’m a fool but I really do. And that alone makes me not fear you.” She had confessed that day. Ever since that day, he began spending more and more time with her. Friendly lunches, dinners, evening strolls and museum tours. He did everything he could to get more time with her. Unplanned, he had fallen in love with the small human.
Today was no different as he sat across her at the coffee table in his bedroom. “How do you find the tea, my dear?” The redhead asked her nervously as she took a sip of the warm liquid, humming in delight when a very nostalgic taste and fragrance hit her. “Oh my…” She whispered, a smile pulling at the corners of her rosebud mouth. “Cinnamon Vanilla tea. My favourite. I love it, Dia!” She exclaimed as he blushed with pleasure. Her eyes widened in realisation. “Did you brew this?” She asked, receiving a gentle nod from the giant demon. “Lucifer once told me how much you like this specific combination. Barbatos acquired it at my request and then went on to teach me how to make it when I begged him. He doesn’t like it when I try to cook something most days with how bad I am at it all.” Diavolo replied with a chuckle, looking up at her just in time to see a tear roll down the apple of her cheek.
“Ariadne?” He asked in alarm, getting up from his seat and kneeling in front of her, worried that he had upsetted her somehow. “I’m… I’m alright, Dia. A little emotional but in a good way.” The woman reassured him shakily, eyes downcast. She couldn’t believe that him, the literal Prince of Hell, had gone through so much effort just for her.She lifted her hand to wipe the remnants of the tear that had escaped from her doe-like eyes when she felt a warm, foreign hand doing the deed for her.
She lifted her eyes, shimmering honey orbs meeting the demon’s golden ones, a million unsaid words, unsaid emotions, being conveyed to each other in the one look. The blonde then cupped his face with both of her small hands before pressing her lips against his. The gesture caused the prince to blank for a moment before he reciprocated, unbelieving of the entire situation as his big hands dwarfed hers against his face.
Once they parted, Diavolo easily lifted her out of the chair, her legs wrapping around his waist as he carried her to his bed. He climbed over her body after depositing her onto the plush mattress, pinning her to it with his own body. Her arms went about his neck, pulling him in for another kiss, this one a lot more passionate than their first. His hands, on the other hand, were on each side of her head, helping him balance his body so as to not crush her.
“I have wanted this for so long…” He groaned against her lips and she hummed in agreement. “Me too. I don’t know how or when it happened but I think I have been in love with you for a while now.” She replied softly, letting her hands trail down his clothed body, getting a feel of his pecs and abs. The demon shivered at her gentle touch, catching her hands by the wrist before pinning them above her head lest they drive him insane.
“You’re so small, so tiny, so helpless right now. Adorable.” The prince spoke, making her blush and look away. “Don’t look away, Ariadne.” He told her, guiding her face back so that she was looking at him once more. “I love you too, little one.” The demon finally confessed, his lips capturing her softer ones in a scorching kiss. This time, he held back none of his feelings for her, pouring them into his kiss as he nipped and sucked at her lower lip. When she gasped, he took the opportunity to deepen the kiss further, shoving his tongue into the welcoming warmth of her mouth and moaning as she glided her tongue against his just as passionately.
His lips then moved to her jaw, littering kisses and occasionally nipping at the skin just as his hands reached down to unbutton her blouse. He looked up at her. “May I?” The fact that he had chosen to ask her made her heart melt. She nodded, immediately gasping as his lips continued downwards, attacking her neck. Meanwhile, his fingers quickly unbuttoned the blouse, peeling it off her body before his hand reached up to gently squeeze her full breasts and tease her perky nipples through the fabric of her red and black satin lace bra. The sensation of the cloth rubbing against the sensitive buds coaxed out whimpers from her pretty lips, her back arching. Minutes past, his louth descended on one of her nipples while his hand worked on the other, switching ever so often until all she could do was moan and beg for more, the room filling with the sweet scent of her arousal.
“You smell so sweet, little one. I can’t wait to taste you~” He growled, making her even wetter at the sound.
As much as the prince wanted to tear her remaining clothes to shreds, Diavolo knew that sending her home the next morning would be tough without her clothes. Therefore, the demon took extra care as he divested the human of her skirt and undergarments before attacking her exposed breasts, sucking and nipping on them until they were covered in pretty red marks. “So soft…” He moaned against the plush mounds, the vibrations making her body shudder.
“Dia please…” She chanted over and over again just as he began kissing down her body, sliding off until his face was level with her dripping cunt. “Look at you… All I have done is play with your nipples and you’re already this wet…” The redhead teased her with a smirk, blowing cool air over her heated nether region. Her breath hitched as she tried to close her legs. However, the demon held them open before placing a leg on each shoulder.
His eyes locked onto hers just as he lowered his head, licking a stripe along her slit. “Oh~ OH FUCK-!” She let out, loud enough to have been heard outside the room as well. But, at that moment, she couldn’t bring herself to care about being too loud. All she could focus on was the demon prince and his touch and the fact that her love had never been unrequited.
She was brought back to reality the moment his tongue brushed against her twitching, throbbing clit. “D-Dia!” She yelped, rolling her hips into the touch, silently begging for him to continue. And he did, diving into her pussy like a starving man. His lips wrapped around her bundle of nerves while his fingers teased her entrance before two of them easily slipped inside. He pumped them in and out of her, steadily building and increasing the pace, adding a third and then a fourth finger, scissoring them and stretching her open. She wanted to believe that he was just teasing her. However, she knew that he was just trying to make things easier for her. With how big he was, she could only imagine how well endowed he was.
As the demon finger fucked her, she could feel her orgasm starting to build, her walls fluttering around his fingers. He began to suck harder on her clit, his fingers still moving at an ever increasing pace. “I’m gonna-” She began, only to be cut off as her orgasm barrelled through her, making her see stars. He kept on with the actions helping her through the aftershocks. “You did so well, little one. Do you wish to continue? We can stop if you so desire.” He told her, climbing on top of her once more, pressing loving kisses all over her face.
“Fuck me, Dia. I need to feel you inside me. Now. ” She responded desperately, her pupils blown wide and her eyes hooded, desire evident in them. Upon hearing her words, he snapped his fingers and his clothes all but evaporated. Her eyes fell on his nude body, taking in every well-defined muscle before they fell on his massive and painfully erect shaft. The girth and length of it had the woman drooling. She groaned when the demon slid his cock along her slit, coating it in copious amounts of her juices before lining up with her waiting entrance.
“Tell me if I hurt you, ok?” He instructed her before slowly, very slowly, pushing inside. She cried out at the intrusion, immediately clenching as tears rolled down her face. “Relax, little one. I do not wish to hurt you.” Diavolo said, his fingers rubbing circles onto her clit to help her along. Before long, she was relaxed enough for him to proceed. “S-so big-!” Ariadne let out in a broken fashion, able to feel every vein and ridge of his member drag along her sensitive walls.
“You’re SO tight… Fuck- ” He growled as he gave a final push, seating himself inside her in entirety. He remained still, allowing her to get used to the feeling of being filled to the brim. “M-move.” She told him a bit later, wrapping her legs around his waist while her hands went about his neck, tangling in the soft locks at the nape of his neck. He slowly pulled out of her, not completely, but enough to let her feel him thrust as he pushed back in before repeating the motions until he was able to build a steady rhythm, ripping loud moans and whimpers at every thrust. “That’s it. Sing for me, love.” He moaned out, feeling her clench at his words.
“M-more… gimme more, Dia.” He heard her telling him and he obliged, increasing the pace and chasing both their orgasms. “Fuck fuck fuck…” She cursed, her nails digging into the flesh of his back as another explosive orgasm began creeping up on her. Diavolo’s fingers dipped between their joined bodies, letting them brush against her clit. That was it. That was what pushed her off the edge as she came with a cry of his name, milking his orgasm out of him as well, causing him to go limp over her before he switched places, letting her lie on top of him, bodies sweaty as they enjoyed the afterglow of their first intimate interaction.
“Are you ok, little one?” He asked her once they had caught their breaths. She looked up at him, her chin resting on his chest. “Yeah. More than ok. I love you, Dia.” She replied, receiving a kiss on the forehead.
“I love you too, my tiny human.”
