They stepped through the Time Door, and the moment Loki felt his powers at his command, he shifted seamlessly into his Jotunn form. At this point, it was almost a conditioned response to stepping onto the beach with Mobius at his side. He turned with a flourish, basking in the hungry look Mobius gave him.
If Loki were anyone else, he’d have blushed at the molten heat in his stare. Instead, he grinned at the way Mobius’ eyes lingered on him as he moved closer, trailing his fingertips down the front of Mobius’ shirt. “I’m starting to think you prefer me in this form.”
“No, I—” Mobius actually looked bashful in the face of Loki’s skeptical look, Loki’s eyebrow arching high to express his doubt after they’d just fucked their way through two tropical apocalypses.
“Come on, Mobius,” Loki teased, resting a hand at Mobius’ hip, cool fingertips digging in just below his belt. “You can admit it. I won’t be upset.”
It was giving him a bit of a complex, but in the opposite direction from the one he’d gotten just a few years ago upon learning of his heritage. Loki certainly didn’t dislike being appreciated; it had been ages since anyone stroked his ego quite so thoroughly.
“It’s not that, exactly.” Mobius leaned in, resting his hands on Loki’s shoulders and smiling up into his face. “You know I love the beach.”
“You do have a knack for picking the most picturesque tropical paradises that are then immediately and mercilessly destroyed.” Loki looked out over Mobius’ shoulder for possible clues. “What’s this one, then? A tsunami? Another volcano?”
Mobius continued, ignoring Loki’s distraction. “There’s just something about cold in the heat, you know? It’s the whole reason for eating popsicles and ice cream on a hot day. Or in your case, ice mead and… fruit, or something.” Mobius shrugged. The shock of stepping from somewhere hot to cold or cold to hot had always sent goosebumps down his arms and a thrill through his body, and touching Loki like this felt very similar.
Mobius pitched his voice low, leaning in to whisper. “It feels nice, you know? Makes you shiver.”
Loki shivered at the way Mobius’ voice rolled over him, so full of promise. “So you do have a thing for it.”
“Well, it’s also…” Mobius gave him a sideways look. “You get this look when I praise you in this form. I know you were told it makes you look like a monster, but really, you’re absolutely gorgeous.” He turned his head, brushing a kiss along Loki’s chest, the cool surface frosty against his lips.
A deeper blue flush crept across Loki’s face, his fingers curling into Mobius’ hips, pulling him closer. “Well, when you put it that way.”
Mobius smiled against Loki’s cheek, moustache tickling the soft skin there. “You’re stunning all the time, and I just think it’s important to tell you.”
“Oh, by all means.” Loki preened, a genuine smile spoiling his attempt to look pompous. “Flattery will get you everywhere.”
Mobius reached down, taking hold of Loki’s wrist and just brushing his thumb over the pulse point, feeling the prickle of chilled skin against his fingertips. “You know what, sweetheart?”
“Hm?” Loki gazed down at the way Mobius stood just inches from him, close enough to feel the warmth radiating from his skin.
“It’s also important to show you.”
“I fully agree.” Loki’s smile blossomed into a smug grin. For all his questions, he wasn’t about to squander the rest of their time here with idle chatter.
“Shall we?” Mobius chuckled as Loki smirked down at him, and placed a proprietary hand at the small of Loki’s back to guide him towards a small beach house, pressing reassuring warmth against his skin.
Loki looked over the wood floor, the desk with its chair, the large bed in the corner with airy hanging drapes. He raised an eyebrow. “This is… quaint.”
“Used to be part of a resort, but most people left when the first quakes started.”
“A volcano, then?”
Mobius smiled. “You’re getting very good at this, Loki. Looks a lot different this time, though.”
Loki beamed. “This time? Let me guess, Krakatoa? 2054.”
“Right in one.” Mobius loved just how smart Loki was, picking up and retaining the smallest details even if he didn’t let on.
Loki gave him a satisfied grin.
“I thought we might try something else this time,” Mobius said, shrugging his jacket from his shoulders and draping it neatly over the back of a chair.
“Oh?” Loki’s interest was piqued, turning his attention from his inspection of the kitschy dècor to hear what Mobius had to say.
“As much as I love to taste you…” Mobius stepped up behind him to catch Loki in his arms, pressing a warm hand against his chest, fingertips just digging into the curved muscle and tracing down his lean side. Mobius pressed a tender kiss to the back of Loki’s neck, sending a shiver down his spine “I’d like to ride you, Loki.”
Loki’s brain short-circuited, and he realized the soft whine he heard was coming from his own throat. He turned, taking in the soft flush on Mobius’ face, the eager, hungry look in his eyes.
“You like that idea? I’m glad.” Mobius grinned, shrugging out of his shirt. When had he unbuttoned it? Loki stared, dazed, at his bare chest. He hadn’t seen Mobius fully shirtless before, and his body was as warm and inviting as his demeanor. Loki took in his broad shoulders, the softness of his slight belly, his chest with its pale hair that shone subtly in the light, faded scars and freckles and other tiny human imperfections that he very much wanted to touch.
Loki’s hand jerked forward as his mind and body caught up, reaching out to do just that, cool fingertips skimming delicately over soft skin. Loki brushed his hand over a delicate nipple that quickly formed a hard peak under his touch. Mobius shivered, goosebumps racing up both arms. His cock twitched with interest, already growing hard in his trousers.
Mobius grinned, leaning up to kiss him. Loki traced his fingers over Mobius’ sides, delighted by the way Mobius squirmed beneath his touch. Dipping down to touch Mobius’ navel, Loki gasped as Mobius caught his wrist and guided his hand lower, cupping both their hands around Mobius’ stiff cock. Mobius gasped against Loki’s lips, his hips jerking forward against the frigid pressure.
“S—hah—see what I mean?” Mobius’ voice wavered as a shiver raced through him.
“Like this? You’re—won’t that be too—” he didn’t get to finish, before Mobius leaned in and kissed him hard, biting at his lower lip and licking into his mouth. Loki moaned, the heat of Mobius’ tongue almost burning in its intensity, enough to make his head swim.
“Don’t you worry about me, sweetheart. I’ve… been preparing.”
“Preparing?” Loki had no idea what he meant, and just stared down at him. Then again, even as a particularly small frost giant, Loki was still head and shoulders taller than Mobius, and larger in every dimension.
Mobius chuckled, palming Loki’s substantial cock through his slacks. “You don’t think I could take this without it, do you?” He pressed a bit more firmly, feeling the cool radiating through the fabric as it swelled and twitched against his palm. “I take it you’re interested?”
Loki nodded, nudging his hips forward against Mobius’ hand and leaning in for another searing kiss. “How did you—”
Mobius pulled back slightly, a smirk on his lips as he pulled back, unfastening his own belt. “You’re a smart guy, why don’t you guess?”
“You…” Loki answered breathlessly, his brain running off ahead of him, filled with a host of lewd images. “You used a toy.”
“Bingo.” Mobius smiled, pleased that Loki was playing along.
“But it didn’t seem that big”—Loki’s eyes went wide, and he lowered his voice conspiratorially—“you have others.” He grinned, a teasing gleam in his eye.
“Are you surprised that it's not the only one I own? Not a lot of opportunities in my line of work, and I have a strict policy against sleeping with coworkers.” Mobius winked, tapping a finger against Loki’s chest to make his point.
Loki caught his finger, and smirked back. “Had.”
Mobius laughed. “Okay, had. You’re the one exception, and I’m not sure it entirely counts, since you’re technically a variant.”
Loki frowned at the reminder.
“I’d say you’re a… consultant. Not the point.” Mobius was starting to blush. “The point is, I’ve been practicing so I can take you without getting hurt.”
Loki swallowed hard at the thought. The mental image of Mobius lying on his bed working himself open, fucking himself open with increasingly larger toys to thoughts of him was almost enough to make Loki’s legs give out with the force of lust that washed over him. Through the rush of arousal, a thought caught in his mind.
“My body temperature in this form is far below yours. Will you be alright?” He looked concerned, his mind back on seriously considering the logistics.
Mobius shrugged, nonchalant. “There’s a freezer in my apartment. I worked up to it.”
Loki stared at him, gobsmacked. “You—”
Mobus nodded. “I’m serious about this, Loki. About you. I know the risks, and I want to make sure everything feels good, for both of us.”
Loki smiled softly, incredibly touched by Mobius’ thoughtfulness and determination. He leaned down to capture Mobius’ lips with his own again, cool against warm. At first, the kiss was almost unbearably tender, and he groaned as Mobius nipped his lower lip, soothing the bruised flesh with a swipe of his tongue. Loki opened his mouth eagerly, allowing Mobius’ tongue to tease against his own, slick and warm and perfect. Here Loki wasn’t quite icy, but rather cool like a mountain stream or the breeze off the sea.
“You’re incredible, Loki.” Mobius pulled back, smiling.
Mobius stepped away to unfasten his slacks, his hips swaying as he tugged down both pants and briefs and stepped neatly out of them, leaving himself completely bare under Loki’s intense gaze.
“No, Mobius. It’s you who’s incredible.”
Mobius met his eyes, ignoring the way his face flushed, and raised his eyebrows at the fact that Loki hadn’t moved to undress. “Should I have left my clothes on?”
“No, no.” Loki tugged at his belt, fingers fumbling at the buckle before remembering himself. With a shake of his head, the rest of his clothes fell away in a shimmer of magic. “Naked is better.”
Mobius chuckled. “Hmm, you are eager.” He turned to the bed, turning down the covers and fluffing the pillow. “Here, lay down. That’ll help.”
Loki did as requested, though stretching out on the bed at his height was difficult. “Are you sure this will be—” he began, looking down the bed to where his calves and feet hung off the end.
“Perfect.” Mobius slipped into bed and straddled him, sliding a warm thigh over Loki’s waist. Mobius sighed as he stretched forward, his cock pressing against the solid plane of Loki’s belly, and kissed him. Lying atop him gave him a pleasant chill, like cool marble, but softer and far more welcoming.
Their lips met in soft, tender presses that quickly grew deeper, Mobius licking into Loki’s mouth as he opened it to say something that dissolved into a groan. Tasting sweetness on Loki’s tongue, he smiled into the kiss as their shared breath formed puffs of fog between them.
Loki stroked a hand up Mobius’ thighs, gripping his cheeks and spreading them, exposing his hole. “You want me to prepare you?” Loki just touched Mobius’ entrance with a fingertip, teasing. Mobius’ breath hitched at the sudden chill. He’d absolutely prepared himself for the numbing cold, but the reality still managed to surprise him.
“I thought you’d like to.” Mobius shivered slightly. “I can always do it myself, but…” He turned to Loki’s ear, his moustache tickling his cheek. “It’s all I could think about last night.” Loki flushed darker, and Mobius smirked at his reaction. “After we left the archives and you went back to your room, I was on the other side of the wall, thinking about you fingering me open.”
“Fuck, Mobius,” Loki groaned, his voice rough with need, “how could you expect me to say no when you ask me like that?” With a smile, Mobius kissed him, an innocent press of lips as Loki teased his entrance with a thick fingertip. With a flick of his fingers to fill his hand with a coating of thick, slippery liquid, Loki started gently rubbing small circles, petting the delicate skin of his hole and gripping a handful of ass with his other hand.
Mobius sighed happily, willing his body to relax. Loki’s fingertips were cool enough for his body to begin to react, but he had thoroughly prepared himself for much more. He pressed a delicate kiss to the corner of Loki’s mouth. “Mmm, it’s a good start, but I’m gonna need more than that,” he teased.
“So impatient.” Loki huffed a laugh, and with a smooth motion he pressed a thick finger into him, sliding it in smoothly past the second knuckle. With a strangled moan, Mobius thrust his hips back onto it, his body greedily accepting the intrusion. Loki took advantage of Mobius’ moan to lick into his mouth, tasting him and seeking out the slick heat of his tongue. Mobius groaned, his mouth falling open to breathe as he relaxed his body, his moustache prickling at Loki’s upper lip as Loki added another finger. The extra digit slipped easily inside, adding more pressure, but still not enough to satisfy him. The cabin filled with obscene slick noises as he continued to add more lubricant, patiently fingering him open until he was dripping wet and pressing back needily against each thrust. Loki curled his fingers as he thrust them, searching for Mobius’ sweet spot.
“Hah—!” Mobius cried out as Loki stroked over it with sudden force, and focused his attention there with a proud smirk, petting the bundle of nerves with determined strokes until Mobius gasped. “Okay!” Mobius pulled back abruptly, his limbs shaking with the intensity of the feeling. “Okay, okay,” he repeated, gasping for breath. Loki’s eyebrows drew up in concern, but Mobius hushed him with a look. “I need you inside me, now.”
“Fuck, how—how do you…?” Loki groaned, his hips jerking up with sheer want as he pulled Mobius down into a desperate, breathless kiss.
Mobius sat up, pressing a hot hand to Loki’s chest that effectively stopped him in place.
“Gah—okay. Stay there. Fingers out.”
Mobius grunted as Loki slipped free, leaving him with an unpleasant feeling of emptiness. He reached behind himself, taking Loki’s thick cock in his hand. “Stroke yourself, sweetheart. Get that beautiful cock of yours nice and wet for me.” Loki’s eyes widened, and he nodded silently, doing exactly as instructed, conjuring additional lubricant to thoroughly slick his cock.
“Perfect. So good.” Mobius leaned down, pressing a soft kiss to his lips as he lined the head of Loki’s cock up with his entrance. “Now stay still, and let me do this,” Mobius whispered against his lips.
Loki gave another tiny nod. Mobius began to lower himself with a slow rocking of his hips, and Loki willed himself not to move, not to press further into the glorious, searing heat slowly enveloping his cock until Mobius allowed it. The difference in temperature pulled the breath from Loki’s lungs in a sharp gasp, his rapid thoughts dimming to a static hum at the top of his mind as Mobius descended upon him. He bit down hard on his lower lip nearly to the point of breaking skin, the pinprick of pain barely able to anchor him.
Mobius’ mouth had merely been a taste—the pressure that had him spilling down Mobius’ throat that first time was a whisper compared to the full-throated howl Loki felt coming on as the tight ring of muscle eased open to admit him into the full, molten heat of Mobius’ body.
“Loki, honey, breathe.” Mobius dug his fingers into the swell of Loki’s chest, catching a nipple between finger and thumb and giving him a slight pinch to distract him. Loki gasped, the much-needed air filling his lungs and clearing his mind a bit.
“Hah—okay. You—” Loki blinked away crystalline tears, looking up at him with wild eyes. He’d never actually had sex in this form, and hadn’t realized he was holding his breath.
Mobius chuckled softly. “Too much? I can stop.”
“Absolutely not.” Loki shook his head, almost frantic. He was still stunned that Mobius wanted this so badly he’d spent weeks preparing, and he didn’t want to ruin it just because he got overwhelmed. Taking a deep breath, Loki brought his cool hands up to Mobius’ hips, stroking gently over the curve of his backside and settling in to help support his weight. “I’m okay.”
Mobius hummed, pleased, his thighs relieved of some tension. “Perfect.” Speared just partway on Loki’s cock, Mobius’ mouth was beginning to water at the anticipation for the rest of it, to be completely filled by it and feel that delightful chill spread through his veins. Even in this proximity to Loki, he was burning up—his skin felt sun-baked, like he’d been basking in a sauna—and he craved relief. The hands on his hips were delightfully cool but not near enough to quench his utter thirst.
“Ok, I need you to hang on, okay?” Mobius furrowed his brow in concentration. “Just a bit more, for me.”
Loki nodded. “Tell me if it hurts?”
“Of course, love.” Mobius smiled. He squeezed Loki’s chest reassuringly, then took a deep, calming breath and continued slowly lowering himself down, the burn of the stretch immediately soothed by the smooth, melting-ice slide of Loki’s cock. Inch by inch, he sunk down, breathing through his nose at the intense, familiar stretch. The refreshing sensation of cool flowed up through his body, filling him like a drink of water after a stroll through the desert.
Loki stared in rapt amazement at the look of blissful concentration on Mobius’ face. His pace was near-glacial, but Loki understood the importance of taking his time, protecting Mobius’ body from the damage he knew he could cause if they weren’t careful. The degree of trust Mobius had in him made his heart ache in the best way, the most precious gift he’d ever been given. He felt truly at ease in his presence—having nothing to hide was incredibly freeing.
At last, minutes later, Mobius’ hips rested fully on Loki’s lap, thighs flush with cool hips, and he let out a shaky groan of satisfaction. “Oh—Loki, you feel incredible.” He lifted himself up slightly, then sank back down, testing the sensation. Another huff of breath was torn from his lips as the cold both numbed the stretch and tingled exquisitely inside him.
Mobius slowly exhaled, the feeling of cool permeating up to his chest. He almost felt like he could breathe clouds of mist. “Help me out a little?”
“Fuck, Mobius…” Loki breathed through his nose, coming back to himself from the rippling waves of heat radiating through his body, centered on their point of connection. He stroked his hands along Mobius’ thighs, and digging his fingers into the warm flesh, he flexed his arms, lifting Mobius slightly and easing him back down.
“Ohh—” A breath was forced out of Mobius’ throat as he bottomed out on Loki’s lap. He’d always been curious, but the moment he saw Loki’s cock in his jotunn form, huge and blue and glistening with frost, he’d craved it like nothing he’d ever seen before. Getting here had been a journey, but now at the end of it, he felt so full, nothing else could compare. It was exquisite, and through his own growing haze of bliss, he could see the rapture on Loki’s face and knew it was absolutely worth it.
“Feels so good to ride you like this.” Mobius gave Loki a crooked smile and raised his hips, rocking them ever so slightly, feeling the way the incredible girth stroked his insides, drinking in Loki’s expression—his dazed smile, the crystalline tears sparkling in his lashes.
Loki took his increased pace as encouragement and echoed Mobius’ movements, holding him as he moved his hips, slowly increasing the depth of his thrusts. Mobius moaned, his mouth falling open at the additional sensation. “Ohhh, Loki…”
Loki had to bite his lip at the way he could feel Mobius’ moan through his cock, pressed up so far into that searing heat. Each new sensation was almost overwhelming; the idea that Mobius trusted him to do this was intoxicating, and he could tell he wasn’t going to last long. His godly stamina and concern for Mobius had held him back up to now, but feeling Mobius fully around him, moving and clenching, the heat of his arousal had grown to an inferno.
“I’m close,” he whispered, wanting to give Mobius some warning. “You’re so hot, I—” Loki gasped as Mobius clenched against him.
Mobius nodded a bit desperately, the pleasure starting to pull him under. “I—I’m close too”—another gasp as he continued his shallow bounce—“just a little more.” His breaths came in sharp pants, abs flexing with the strain of holding himself upright. Loki moved his hands up along Mobius’ sides and back, stroking the soft skin and adding extra support, and Mobius gave him a soft, blissful smile. “Loki—hah—you’re perfect—ahh—”
The praise, Mobius’ determination, and his exquisite heat and tightness all swirled together in Loki’s mind, and he couldn’t hold back his moan. He was hanging on by a mere thread of willpower. “Mobius, I’m—”
Mobius nodded, and reached down, gripping his own leaking, aching cock with a still-slick hand and stroking it quickly, hurtling towards the edge. “You feel so good, sweetheart. Go ahead and come for me.” He looked down at Loki, shining blue eyes meeting liquid ruby, and smiled. As instructed, Loki nodded frantically in another two thrusts he came, his eyes rolling back as pleasure flooded his veins. Mobius felt a shock of ice pulsing deep, deeper than should be possible, and gasped as the world shattered into icy shards of bliss and he came hard, painting Loki’s cool chest with a white-hot line of heat.
Mobius leaned heavily against his hands and gave him a dazed, happy smile as Loki lowered him down, collapsing limp against his broad chest. Mobius was so cold, his lips tinged with blue, and with a sharp pang of worry Loki quickly shrank back into his warmer aesir form. His softening cock slipped out wetly, trailing rapidly-melting slush, and he used his magic to thoroughly clean and remove all traces of cold from Mobius’ skin.
Mobius sighed blissfully as he lay there, slowly absorbing the renewed warmth from Loki’s body beneath him. With another flick of his fingers, Loki conjured a fluffy blanket up from the foot of the bed, warming it with magic and pulling it close around them as he smoothed his hands over Mobius’ limbs, massaging warmth back into chilled muscles.
“Thanks, sweetheart,” he murmured.
Loki smirked, stopping what he was doing to press a warm kiss to Mobius’ still-cool lips. Frowning at the temperature, he pressed his tongue to the seam, licking inside when Mobius sighed happily, letting him do as he pleased. Loki kissed heat back into Mobius’ mouth, only pulling away when he was satisfied that he was warming up.
Mobius looked at him, eyes hazy, his lips red and kiss-swollen, and Loki’s heart felt full to bursting. “That was amazing, kitten,” he murmured, “can we stay here for a while?”
Loki groped around beside the bed for the TemPad, nearly dropping it as he brought it close enough to focus on the tiny numbers through the pleasant fog in his mind. “We have… six hours.”
“Mmm, perfect.” Mobius stirred, lifting his arm slightly, where it wobbled before sinking back to the bed.
He tried shifting his hips and only succeeded in sliding partially off of Loki, noticing for the first time the deep, hollow ache in his backside as his hip touched the bed. “Wow. Yeah.” Mobius chuckled, the sound reverberating into Loki’s chest as he curled against him, pillowing his cheek against his shoulder. “I’m gonna feel this for days. Worth it, though.”
“Mmm, I’m glad.” Loki hummed, pressing a kiss to the top of Mobius’ head. As much as he could tell Mobius enjoyed it, there was always the worry that he was too much.
“Can you set an alarm for four hours? I don’t… I don’t think I can move yet.”
“I can help you lay down, let me—”
Mobius was limp and heavy with exhaustion, and as Loki began to shift, he mumbled sleepily. “Mm—wanna stay here with you.”
Loki grinned at Mobius’ adorable, loopy softness as he began to snore softly, his cheek pillowed against Loki’s chest. “Of course,” Loki murmured, pressing a kiss to the top of Mobius’ head, rousing him just enough to curl in closer. I’m not going anywhere.
