B - Bittersweet

"Hey Loks. You asleep?"

"If I said yes, would you refrain from disturbing me?" The god's voice was a low purr, and radiated contentment despite the cheeky words it formed.

"Nope."

Loki sighed and rolled onto his stomach, resting his cheek on his own forearms. Tony smiled, using his fingertips to brush several silky, raven locks away from Loki's emerald eyes. The god exhaled and frowned ever so slightly, sending a chill down Tony's spine.

"I'm tired, human. You have succeeded in your endeavors, what more do you need?"

"Note to self, Loksters is grumpy after-"

"Shut up, Tony."

"Oh, so now I have a name? Well, I guess you did scream it a couple times when-"

"Anthony..."

"Fine, fine, I'll stop." Tony smiled and began absentmindedly running a finger up and down Loki's spine. The god arched into the touch and closed his eyes.

"I have a question," Tony murmured, removing his finger as incentive for Loki to respond. The god's brow furrowed and his eyes opened a sliver, green irises glittering from underneath the pale lids.

"I'm listening."

"Why me?"

Loki rolled his eyes. "Oh please, Stark. Don't go soft on me." Curiosity remained plastered on the human's face. "You're...compelling. I want to decipher what lies behind your eyes; I want to pick apart your soul and analyze what makes you different from all the other imbeciles that inhabit this planet."

Tony blinked, before a wry smile spread over his lips. "I would be terrified if that came from anyone but you, babe."

"Babe? No."

"What would you prefer then? 'My king'?"

"That does have a pleasing ring to it."

Tony chucked. "Uhh, how about no? If your head got any larger it'd probably blow the roof off this building."

Loki didn't speak, but a small smile quirked the corners of his lips. "I believe it's my turn for a question."

"That seems fair, I guess."

Loki's smile morphed into a smirk as he pushed himself onto his elbows and slid over to Tony, his lips hovering an inch over the man's throat. Kisses ghosted along the human's skin, up over his jaw to the corner of his lips. The god could feel Tony's breathing quicken and he allowed his eyes to flutter shut as he closed his lips over the human's; his human's.

Tony kissed back hungrily, twining his fingers through Loki's silken hair. A thick, sluggish warmth began to spread through the man's stomach and he gasped, pulling himself down into the pillow to escape Loki's searching lips.

"Hey now, I'm great for a few times a night, but I don't think-" His words were cut short as the god above him snarled and all but attacked his mouth, shoving his tongue between Tony's teeth before the human could protest again. Throwing caution to the winds (after all, the worst that could happen was still pretty awesome), Tony returned the kiss fiercely, allowing Loki to take command until their lungs were screaming for air.

When they broke apart, Tony laughed breathily and gazed into the gorgeous eyes shimmering above him. "Was that your question?"

"No."

"Well then-"

"You asked me once, what a silver tongue tastes like... Why don't you tell me?" The god expected Tony to laugh, or at least smile, but the man remained serious as he contemplated his answer.

"Bittersweet."

Loki tilted his head in confusion. "Explain."

"It's...you're... I can't describe it."

Loki shot an unconvinced glance in Tony's direction as he flopped back down beside the human. Tony sighed.

"It's...wintergreen and magic."

"And that equals bittersweet?"

"Well...technically we're not supposed to be together, so it's scandalous. And, no offense, but you're kinda loony sometimes, and aren't exactly the most loving all the time." Loki grinned and conceded. "But you're a god; you taste like power and vengeance and electricity."

"Poetic."

"I read it in a book."

"Romantic."

"I thought you wanted to sleep." Tony replaced his hand on Loki's back, rubbing out small circles in the lean muscle. The god hummed rapturously, relaxing into the plush mattress beneath him and allowing himself a moment of quiet happiness.
