Prompt: Darcy is getting intimate with Loki in his Jotun form for the first time, but things quickly take a turn for the awkward when her tongue gets stuck to him, a la A Christmas Story.

"This is foolish," Loki pouted as Darcy straddled him, running her small hands up and down his chest. Darcy rolled her eyes at him and bounced herself lightly on his stomach.

"Come on, Snape, pony up. We had a deal. I play guinea pig for your weird-ass experiments and I get some naughty-in-blue time. Look, I even dressed the part." She gestured towards her breasts, barely covered in icy-blue lace, a snowflake pattern over the nipples. Her panties matched prettily, but Loki couldn't see the snowflakes from his position. He scowled as Darcy bounced again, this time brushing her ass down against his groin. She grinned at him as she felt him harden against her. "Come on, we had a deal. And even if we didn't, you totally owe me for that color-switch spell." That particular spell had been an attempt to heighten her night vision (an experiment requested by SHIELD). Darcy had wound up wandering around for three days with all of her colors confused. What was black became red, green to yellow, red to purple and so on. For three days, Loki had looked like a bedraggled Ronald McDonald and Darcy had been banned from driving until the spell wore off.

"I'm not responsible for any accidents or mishaps you had." Loki hissed as Darcy rocked back, her breasts swaying temptingly. "It's in your contract."

Darcy's response was to run her tongue over his lips. "Pay up." She pulled away when he tried to catch her lip between his teeth. "Or I take this back to the store and leave you all by your lonesome." She ran her hands over her breasts and down her stomach, over his ribs and up to his shoulders. Loki's breath hitched and he rolled his eyes.

"Fine," he growled and was rewarded with a kiss. His hand wandered up to her breast and squeezed lightly. Darcy moaned into his mouth and he sucked on her tongue. Darcy finally pulled herself away gasping, hair disheveled and one pert nipple peeking out from the top of her bra. She watched him expectantly, giving him a winning smile. Loki locked his eyes on Darcy and slowly revealed blue skin. Darcy gasped as cobalt swirled across his chest and spread across his body. Light ridges curved across his muscles, accentuating the iron strength within him. The chill spread up his neck and across his face, finally reaching his eyes, darkest red bleeding into them. He watched her face, waiting for the imminent rejection. But Darcy's blue eyes held only curious fascination as she ran her fingers gently across the ridges and skin.

"You're cold," she said then grinned mockingly. "Duh, of course you're cold. You're a Frost Giant." She traced the ridges along his neck and cheekbones, leaning forward to rest her forehead against his. "You have no idea how hot this makes me," she whispered against his mouth before sliding down his body. Silent laughter in her eyes, Darcy hooked her fingers into his underwear and slid them down his long legs. She grasped his hard length confidently before suddenly gasping. "Dude, your penis is like an icicle. That's so weird." She grinned at him again. "This is gonna be awesome." The woman gently blew warm air over his head and Loki hissed in pleasure.

"Don't tease me, woman. Get on with it."

Darcy tsked at him. "Patience, young grasshopper," she said in a sage voice, her face serious for a few moments, then she burst out laughing. "The patient shall be rewarded," she cackled. Loki couldn't help but smirk at her tomfoolery before giving her a stern look.

"I've been patient long enough. You've got me this far, don't stop now."

"Okay, okay, okay," she gasped, wiping tears from her eyes. "Wow, sorry." She gave the base of his penis a gentle squeeze and pressed her tongue against his head.

Loki wasn't sure who was more surprised when her tongue didn't slide across him as expected and instead stuck to him like glue. Darcy's eyes widened comically as she tried unsuccessfully to tug herself free. The sensation felt wonderful to Loki, like a massage to his head, but less so for Darcy.

"Hey," she garbled. "Le' go."

Loki laughed for a moment as Darcy glared at him, an effect ruined by her tongue hanging out her mouth like a dog.

"Du'. Seisly. Ib stug."

"What was that? I couldn't quite hear you." Now he was laughing uncontrollably. Darcy narrowed her eyes at him and punched him in the thigh.

"Helb me, asho."

Still chuckling to himself, Loki sat up and put his hands under her jaw. "Just relax for a moment," he said while he searched his mind for the correct spell. He hummed lightly as Darcy closed her teeth on his thumb and bit down. The movement forced her tongue to pull back into her mouth, so that her lips brushed against his head.

"Hurry ub."

"Weren't you the one who asked for patience?" Her teeth tightened on his thumb and exquisite pain started to blossom up his hand. "Darling, you're not making a good case for getting unstuck."

"Ib goin to ki' ooh."

"Hey, Lokes, do you know where Darcy is? Jane's going ballistic—," Tony walked in without knocking. The playboy stopped dead in his tracks before raising his eyebrows at Loki. "Blue, huh. Want me to lead Jane off?"

"That would be appreciated," Loki said solemnly. "And, also, do you think you could bring us some warm water. Darcy's feeling a bit chilled."

"Sure thing, Lokes, just spill the beans later." Tony left the room, a smirk across his face.

"'Our a de' man."

"I aim to please."
