This time, however, he sets something off in Mikaela that is only settled with something that can ease the sexual tension in the room. Notes This is for my dearest Princess, my Yuu-chan. After a rough weekend, we both needed this. I just needed to write it and she needed to read it. And so here it is, a smut piece for you for being a great friend, a great roleplay partner, and for being so strong through those hard times. Also because you sort of demanded it so I felt obliged to obey. xD lmfao! Love you Princess! I hope you enjoy- and I hope the rest of you like the smut as well ;) P.S. - If you get the reference to the title, I love you so much. So, so much. A+ for amazing flawless taste in music made by a literal angel on earth with the vocals of an inhuman god c; “Mika.” He was doing his best to keep his eyes turned away. Mikaela swallowed thickly, trying not to let the affectionate name get to him. Yuuichirou had dozed off only moments ago, and hearing Yuuichirou’s voice, now deeper and venomous… Mikaela knew he had turned. Mikaela checked his watch to make a mental note of how long it would take, approximately, for Yuuichirou to return as himself. “Mika,” Yuuichirou said. “Mika, come on. I know you can hear me.” Mikaela ignored him still. “Ne, why don’t you unchain me? You know, this is uncomfortable for me.” “I don’t care about your comfort, demon,” Mikaela growled, shooting a glare over his shoulder. “Oh?” Yuuichirou hummed. “But I’m your precious Yuu-chan. How could you treat my body so harshly? Have you no consideration for me?” “No,” Mikaela said, “because you’re not Yuu-chan.” A dark laugh was Yuuichirou’s response. Mikaela stood, ready to leave. Their exchanges always left him stressed out. Just as he took two steps forward, Yuuichirou clicked his tongue. "What’s with the soreness?” Yuuichirou complained. “Oh, wait. No wonder my back hurts. You were kind of rough on me yesterday, Mika.” Mikaela tensed, understanding the implications of the demon’s taunt. He swallowed and his fingers curled into fists. “Mika, why don’t you show me what we did yesterday?” Yuuichirou spoke lightly. “Come here, I want to touch you, Mika.” “No,” Mikaela said firmly, yet he couldn’t move his feet. A shudder passed through him and he let out a shaky breath. “I can’t really touch myself like this, you know…” Yuuichirou complained. “With my hands chained and all… ah, but just thinking about it, looking into Yuuichirou’s memories… oh, what expressions you made, Mika.” Mikaela turned around fully, fury blazing in his eyes. A similar glinting red was reflected back at him, and Yuuichirou’s lips lifted in a smirk. Mikaela’s eyes flickered down and he noticed a straining hardness between Yuuichirou’s legs. “That’s better,” Yuuichirou bit his lip slightly, then moved his legs, attempting to rub his thighs along his length. The slight rub he got made him hiss and he locked his eyes with Mikaela, who was watching silently, coldness in his eyes. “You never would look at Yuu-chan like that, now would you?” “No,” Mikaela said simply. “He’s inside, you know,” Yuuichirou said lazily. “We’re in the same body. Fucking me is like fucking him. I’ll make the same pretty faces and sounds as-“ Yuuichirou was cut off. Mikaela was suddenly before him, his vampiric speed making his movements almost unseeable. He was crouched down, one hand slammed against the wall next to Yuuichirou’s head. “Yuu-chan and I make love,” Mikaela snapped, eyes blazing threateningly close to Yuuichirou. “As for you and I, that would be fucking.” “Sounds intriguing,” Yuuichirou chuckled and tilted his head back, lining up their eyes better. “Why don’t we try it?” Mikaela’s eyes were dark and he narrowed them. He was silent, considering standing up when suddenly, Yuuichirou lunged forward, only a hair away from Mikaela. “If you don’t, I’ll torture Yuuichirou with memories of abandoning you,” Yuuichirou’s voice seemed to fluctuate with some sort of deeper tone, leaving a fittingly demonic echo ringing in Mikaela’s ears. Mikaela was blinded by his fury at the demon’s threat. “You parasite,” Mikaela snarled, then slammed their lips together, feeling the demon’s fangs click against his own. A low rumble vibrated Yuuichirou’s throat and he shoved his tongue into Mikaela’s mouth. It tasted like Yuuichirou, despite the sharp fangs to match Mikaela’s own. Mikaela slowly pulled back, hissing as Yuuichirou’s fangs pricked at his bottom teeth. He reached forward and hurriedly unbuttoned Yuuichirou’s uniform and belt, clawing at it and leaving it hanging loosely around Yuuichirou’s shoulders. His torso was revealed, and Mikaela knew he couldn’t take the uniform off entirely, at least the upper half, without releasing Yuuichirou’s arms. That was a horrible idea. Yuuichirou would certainly try to fight. Mikaela narrowed his eyes and removed his own gloves, tucking them under his belt quickly before leaning forward again. This was the demon, but Mikaela was heated, his body affected by the taste and smell and feel of Yuuichirou’s body. “Dammit,” Mikaela growled, leaning closer and running his hands up and down Yuuichirou’s body. Yuuichirou trembled under his touch and he tilted his head back, exposing his throat. Yuuichirou’s body was still marked with fresh hickeys from the night before, when they made love… Mikaela pressed his thumb against the one on Yuuichirou’s hip, making Yuuichirou’s mouth fall open in a whimper. Mikaela tilted his head and sucked hard on one particularly dark hickey on Yuuichirou’s collarbone. “H-hhah!” Yuuichirou gasped and trembled under his mouth. “M-Mika, Mika…” For a second, he really sounded like Yuuichirou. Mikaela felt nervous, but he was furious that the damned demon had threatened to taunt the real Yuuichirou with nightmares. He didn’t know how else to shut him up. Mikaela was hard, and not just from his natural physical reaction to his lover, but from his incredibly hot, seething rage. Mikaela crawled closer and sat on Yuuichirou’s lap, rolling his hips forward and grinding their clothed erections together. Yuuichirou whined and rocked back against Mikaela, eyes hazy. He gasped heavily, breath hot against Mikaela’s mouth. He reached forward and slid his tongue along Mikaela’s parted lips, prodding at the inside with a devious smirk lifting the corners of his mouth. “Mika, c’mon… harder,” Yuuichirou whispered, then nipped down on Mikaela’s bottom lip. Mikaela let out a small gasp at the sharp pain from Yuuichirou’s fangs- a stinging reminder that the man before him wasn’t really Yuuichirou. It made him all the more aggressive. Mikaela reached down and hurriedly unbuckled Yuuichirou’s belt and pants. He shoved the pants down roughly, pausing to yank off Yuuichirou’s boots from his calves. He tossed them away and continued to pull off Yuuichirou’s pants until they were thrown aside in a crumpled heap. Mikaela reached forward and unforgivingly gripped Yuuichirou’s length through his boxer shorts. Yuuichirou rolled his head back and gasped shakily, shoulders trembling at the sensations he felt. “You’re… you’re disgusting,” Mikaela growled, rubbing his palm heavily on Yuuichirou’s clothed erection. The fabric got wet and hot, making Yuuichirou tremble and a needy gasp fall from his lips. Mikaela clicked his tongue, unamused. “Disgusting, making me do this so you don’t torture Yuu-chan…” “H-Heh, c’mon, Mika, you’re enjoying yourself too, just a-ahhh…” Yuuichirou sighed, rolling his hips into Mikaela’s touch. He bit down on his own lip, pricking it and drawing blood. Mikaela’s eyes dilated, and his senses flamed at the scent of blood. His mouth watered and he focused on the red droplet, watching as it slid over the elegant curve of Yuuichirou’s lip and made a faint trail down his chin. When Yuuichirou smiled, Mikaela looked up at Yuuichirou’s eyes, noticing the downright evil glint in the red irises. Mikaela glared at him with hatred, pressing his hand harder into Yuuichirou’s crotch and watching as his expression faltered and he had to glance away from embarrassment. “So even demons can get flustered…” Mikaela murmured, then pulled his hand away, not failing to notice how Yuuichirou’s hips followed his hand as it left. He gripped the edge of Yuuichirou’s boxers and with a few swift tugs, they were off and Yuuichirou spread his legs, needy and eager. Mikaela couldn’t help but to admire the sight. If he disregarded the situation and didn’t look up, the lower half of Yuuichirou’s body was still Yuuichirou. He was still stretched from the night before, but Mikaela wouldn’t go about sex without preparing Yuuichirou in some way. He reached into his pocket, where he always had some lubricant (Yuuichirou sometimes demanded sex at the most random times). After coating his fingers, he hardly warned Yuuichirou before pushing two fingers inside. “M-Mika-hahnn!” Yuuichirou’s toes curled and he squeezed around Mikaela’s fingers. Mikaela moved them deeply, eyes fixated on Yuuichirou. He could tell Yuuichirou was still stretched pretty well. He wasn’t in much pain from the intrusion, merely shocked by it. He only had to move his fingers in and out for a moment before he removed them, unzipped his pants and took out his erection, then coated his dick in lubricant. “S-So eager, Mika…” Yuuichirou laughed weakly, voice shaking as he watched Mikaela’s dick get slicker with each flick of his wrist. “You were so opposed to even looking at me, I’m shocked that you eve-ah-ahhh… Mika…” Yuuichirou grit his teeth as Mikaela entered inside of him, his hands curling into fists. Mikaela gripped his hips and pushed himself inside slowly. He was being gentle during the process, since it was Yuuichirou’s body, but he knew Yuuichirou liked it rough sometimes, and he wanted to shut the demon up sooner than later. Once he felt the time was right, he’d make sure to please the demon, but mostly Yuuichirou’s body. “C’mon, Mika,” Yuuichirou hissed past his fangs. Mikaela looked up at him, glaring at the pointed horns sticking from his hair and his glinting scarlet eyes. “I’m ready, just… move, already.” “I’ll move when I want to,” Mikaela growled, but he began thrusting inside of Yuuichirou anyways. The friction made him clench his teeth and he shivered, moving slowly, feeling Yuuichirou tighten and loosen around him. Yuuichirou panted heavily, tense and shifting as Mikaela worked himself into a pattern. “Eh… you’re not doing so well,” Yuuichirou pouted. Mikaela glared up at him. “I mean, I could always send him those nightmares right- hhnnh!!” Mikaela slammed himself inside and Yuuichirou’s entire body jerked. He yanked his wrists hard against the cuffs, making them rattle. He threw his head back so fast that the tips of his horns clacked against the brick wall, and he cried out softly from the shock. “I know how to treat Yuu-chan’s body,” Mikaela growled, thrusting in and out relentlessly, watching as Yuuichirou cried out and squirmed. “You are just an impatient, pathetic demon… You’re a parasite, vermin, leeching menace…” Mikaela hissed out with every thrust, making sure to jab at Yuuichirou’s prostate every time, watching as his eyes fluttered and a red blush darkened on his cheeks. Saliva began to collect between his teeth as he panted hotly, and he licked at it messily, whimpering and rolling his hips back onto Mikaela’s dick as he thrust in over and over. “M-Mika, Mika, Mika…” Yuuichirou panted out, arms jerking and tugging against the chains. “Mika, let me- let me out, Mika-“ “I’m not… falling… for your tricks,” Mikaela grunted as he thrust in deeper, and he grabbed Yuuichirou’s thighs, pushing them back and gripping at the skin tightly. Yuuichirou whimpered and his hands shook tremendously, clearly itching to be freed. “Mika, I want to t-touch- aahn- touch you, too…” Yuuichirou squirmed and begged, but Mikaela ignored his pleads, rolling his hips and jabbing right at Yuuichirou’s sensitive part. Yuuichirou’s body jerked familiarly, and Mikaela smirked, leaned down and bit down on Yuuichirou’s ear. “I win, demon,” Mikaela snarled, just as Yuuichirou bucked, cried out and orgasmed. He spasmed slightly and leaned closer to Mikaela’s warmth, whimpering his name shakily as Mikaela came inside of Yuuichirou. He pulled back slowly, examining the blissful smile on Yuuichirou’s face, the flush on his cheeks and his gorgeous, thick eyelashes, fanned out heavily over his… … still-red eyes. Mikaela sighed and pulled out of Yuuichirou, then tucked himself into his pants and zippered up. He stood and went over to the table nearby, grabbing tissues and returning to Yuuichirou, who he cleaned off and re-dressed. Yuuichirou was still rosy-cheeked and dazed, but the demon was making him grin and laugh and give Mikaela devious looks. “Mika, how about another round, eh?” Yuuichirou whispered hoarsely. “I can go again…” Mikaela didn’t even respond this time. He checked his watch and noticed it wasn’t much longer to go. Without saying anything else, he stepped outside of the shed where Yuuichirou was chained, taking in a deep breath of fresh air. “Yuu-chan…” Mikaela whispered as he looked at the sky. He swallowed and studied the clouds drifting across the sky lazily. “Come back quickly… so I can make love to you properly.” Please drop_by_the_archive_and_comment to let the author know if you enjoyed their work!
