The Best Medicine

Summary:

"It should kick in soon." Her voice was comforting and buttery. He wanted her to wrap him in it, fold him in the whisper of her words. He felt the medicine creeping to the edges of his skin, a warm trickle as she rubbed his shoulders. A burst of relief washed through him, the pain starting to feel distant.

Aang is recovering after recently getting hurt. Katara offers him some very effective medicine.

Work Text:

Aang felt a sting in his arm as he repositioned in his bed, the radiating burn reminding him of his recent failure in the city.

Okay, he didn't necessarily fail. He and Toph successfully captured the two earthbenders who attempted to ambush him, but in the process, he suffered the consequences of letting his guard down. The memories of being thrown to the ground and nearly crushed made him wince in embarrassment. Now, he lie in bed with bruises across his body, cuts along his face, and his right arm pathetically held in a sling. He was pretty sure he had broken a finger on his left hand. To him, this certainly felt like failure.

"Shit," he groaned as his body ached with soreness. He had been confined to this bed for over two days now, Katara insisting that he rest while he recovered. She was able to heal the majority of his arm, but the complicated fractures were going to take time.

Sighing, he rolled his head to the side and stared at the textures of paint on the wall. The boredom was almost worse than the pain.

"Aang, I'm coming," Katara called from across the home. He immediately lit up at the sound of her voice, turning his head to wait for her entrance. He was due for pain medication. He could hear her mix the medicine in the kitchen, the pages turning as she referenced her pharmacy textbook. The edges of his face turned up in a grin at the thought of her swaying in the kitchen, tapping her lips as she read through the recipes.

It was just them in the home since the ambush. The acolytes had begged to stay for support, but Katara urged them to visit their families in the city while Aang healed. Aang was silently thankful for that. The state he was in didn't exactly put him in the mood for constant visitors. He heard the sound of Katara's hum as she approached his bedroom, her tone dreamy and vibrating and warm. Well, except for her. She could visit whenever she'd like.

She softly knocked – a weirdly cute formality, they never knocked – and entered the room. In her hands were a small medicine cup filled with a green liquid, a glass of water, and some extra bandages. His eyes immediately latched onto her flowing pleated skirt brushing up against her thigh as she walked towards him. He knew she went to the city this morning to buy extra ingredients, and cursed at himself for not being able to see her wear that skirt in the store as she rummaged through the aisles. He imagined her bending over to check something on the lower shelf-

"Aang, how are you feeling?"

His eyes snapped up as she sat on the edge of the bed, placing the items on the nightstand. A tiny shiver of guilt snaked through him as he blushed. It had been a few days since he had, well, had relief, and his mind was starting to pacify the boredom with incredibly overwhelming visions. Last night, he dreamed of pressing her against the wall, holding her up while she demanded in his ear to go faster, fuck, go faster. The dream wasn't even fabricated, just a replayed memory of their night after a date last week. Aang had woken up in pain, not just in his arm. He spent the rest of the morning frustrated as hell that he couldn't do anything to solve his predicament, his injured arms mocking him. Anger had swelled inside him as his hips had dug into the mattress below him. Stupid fucking ambush.

"I feel okay. Thanks for checking on me, baby."

Katara held her palm to his cheek, his face melting into it. "Are you sure? You look red. Do you have a fever?"

Aang almost laughed at himself. "No, I'm okay."

She leaned forward to kiss him chastely, smiling before grabbing the medicine cup. "Have you been in pain?"

More than she knew. "Yes."

She pouted and showed him the medicine. "I was afraid. I brought the usual stuff, but I made it a little bit stronger. Is that okay? It might hit you pretty damn hard, but it should definitely take the pain away."

Aang nodded. "I don't care, I'll take it."

He secretly liked the concoction that Katara made for him. She used all of the prescribed ingredients, yes, but she also included a rare root that they brewed into teas for special occasions. It had an intoxicating effect, overwhelming bliss within five minutes of taking a sip. Perfect for the rare event, and absolutely a pain reliever, although illegal in many nations for that very reason.

She brought the cup to his lips and tipped it, him eagerly swallowing as much as he could, following with some sips of water. As he caught his breath, she held his face and examined some of the cuts. He noticed her eyes darting down his shoulders, staring. Her eyes raked a little lower, likely noting the fact that he lay only in his underwear. Katara had insisted of that, stating that the extra material would only further irritate his wounds. Of course, he had teased her plenty for that, but still obeyed. He took the opportunity to gaze at her chest, her skin disappearing under her tank top. She was now looking back at his face, but he didn't even care to look away from the curve of her breast.

"It should kick in soon." Her voice was comforting and buttery. He wanted her to wrap him in it, fold him in the whisper of her words. He felt the medicine creeping to the edges of his skin, a warm trickle as she rubbed his shoulders. A burst of relief washed through him, the pain starting to feel distant. "I'm sorry you've been hurting. Here, let me heal some more of your scratches."

With droopy eyes he watched her sit up on the bed and straddle his thigh, her waterbending a nearby bowl of healing water to surround her hands in a blue glow. He tried not to gasp as he felt the sensation of her panties along the skin of his thigh, underneath her skirt. She bent over and healed a few small cuts along his ribs, before checking on a rather large gash along his waist. Her lips twisted in concern. She pulled down on the waistband of his underwear to inspect it further, the tickle of her fingers making him instantly hard.

She noticed. He knew she noticed. She pretended like she hadn't, her hands hovered over the area as she dutifully did her work. The medicine was really starting to kick in now, the healing adding to his sense of relief, his mind floating as he stared at her figure while she worked over him. The blue glow lit up her face, casting dancing shadows across her eyes.

"You're really pretty," Aang murmured. Katara looked up and giggled at him, her cheeks filling with blush. He noticed something different in her eyes, but he couldn't quite put a finger on it. She looked like she had something she wanted to say. He gazed at her, attempting to decipher the look on her face, but it was proving to be difficult to think past the buzzing euphoria of the medicine. "I've missed you, you know. A man can get very... bored."

She raised an eyebrow. "Is that so?"

"'Tis so. There's no one here to occupy my time."

"I'm sure you've been doing a lot of meditating."

Aang couldn't hold back the laugh this time. He meditated the first day, but he hadn't been as successful the next couple days. Every time he tried to focus, his mind darted to her. If anything, he'd done a lot of meditating on the hundred different ways he planned to fuck her when his arms were fully healed.

"I've been lonely," He settled on. He looked up at her, holding her eyes. He wondered if she could read his intentions from them. She huffed out a breath, flustered.

She continued healing, although he felt her start to move along his thigh. It was inconspicuous at first, her dragging her hips forward, until it dawned on him that she was maintaining a rhythm. He looked to her face as her eyebrows started to furrow, anxiously glancing at his blank expression. He could only blink in awe as a lazy smile grew on his face. The medicine was in full effect, and he almost felt drunk on it, surely amplified by the intense lust burning in his abdomen as she moved. He knew she wanted him.

He spoke to her in a grinning daze. "What are you gonna do to me?"

Katara leaned down and captured him in a kiss, her tongue protruding into his lips as she dug deeper. He let out a noise into her mouth, shocked at her forwardness, but thrilled at the touch. Aang felt her thigh press against his raging hardness. She sat back up, sheepishly waterbending the healing water back to the bowl.

She looked incredibly embarrassed, but continued her grind, and it was fucking adorable. He felt his breath catch when she bit her lip. Was he dreaming again? Maybe the medicine knocked him out.

"I'm sorry, Aang," she sighed nervously, still moving her hips back and forth along him. The fabric of her panties was starting to soak through, creating a new sensation of wetness on his thigh. He felt his entire body clench as he glanced between her face and his thigh, overcome with desire for her. Her hands rested on his abdomen. "It's just been a few days, and– I couldn't resist when you when you just looked at me like that, and– I'm sorry, I just really need you."

He was able to pick up on every other word of her rambling explanation, the soothing calm of his cognitive state making him curious to her anxiety. Yes, he now realized, she was using him, but the thought of this only turned him on more. Why was she apologizing? This was better than any daydream, and her apprehension was almost amusing. Her hips continued to move back and forth as she let out small moans in pleasure. His hips bucked involuntarily.

Aang didn't usually struggle for words this much. They often laughed about how much they talked in bed, as if they were reading each other the morning paper while he railed her from behind. Now, he could only stutter, his longing and his intoxication overshadowing his ability for words.

"That- that's okay," he managed, and he watched as her eyes softly closed while her fingernails dug into his sides. He wished he could grab her, suddenly becoming incredibly aware of his limited mobility. Stupid fucking ambush!

"I knew you'd understand, you know how I can barely stand being without you for a day, let alone three." She sighed again as his mind burned with the image of what she must look like under her skirt. He wanted to see her, badly. He could feel her slick outside of her panties, coating his thigh.

Aang reached his left hand up to lift her skirt, Katara gasping and pushing him back down. "Aang, no, you know you're not supposed to use your arms." He groaned as she softly pinned his forearm to the bed and continued. Her other hand came up and lifted her skirt. "The last thing I want is you getting more hurt. Here, I'll hold it for you."

He looked down to see lacy, silky underwear, soaked with a thick line of her fluid. Most of her slick was glistening on his thigh.

"Holy shit, Katara," he gasped. He felt himself throb as he watched the skin of her folds while they rubbed up and down. Her soft whines caused bursts of longing to shoot down his core, knowing that she was getting pleasure out of the friction she created. He thought his heart might beat out of his chest. He winced, his shoulders heaving. The eroticism, combined with the intoxicating effects of the medicine, was almost too much to bear.

She slowed, concerned. "Oh no, are you in pain?"

Aang cursed and grunted, looking down at his cock and back to her in disbelief. Her eyes widened as she looked at him and giggled. "Oh."

Aang was nearly breathless as his girlfriend's intentions soaked in. She had come in here, in that skirt, and was practically shamelessly using him for her own pleasure. Did she not know that would drive him crazy?

A devilish look flashed across her face as she reached for him over his boxers, wrapping her palm around his length. She moved her wrist torturously slow. Aang grit his teeth and let out a growl.

"I'm losing my mind, Katara," he pathetically gasped from under her. He noticed a smirk before she tilted her head back and exhaled in ecstasy. The friction was causing her panties to move partly to the side, exposing most of her folds. He couldn't believe how wet she was. "Shit, you're soaked, baby." He gasped again, then thrusted into her palm.

She hovered over him once more, her lips making their way to his ears, biting down. "And you're absolutely throbbing." A shiver went down his neck as she kissed and licked a spot under his jaw. "I'm sorry, Aang," she sunk her teeth in his shoulder, then kissed the mark it made. "It seems I've been neglecting you."

He felt his eyes roll to the back of his head when she pulled him out of his underwear and began pumping him. His muscles began to flex, his chest rising from the mattress. "Katara- you- I-"

She moved her lips back to his ear, shushing him. "You're supposed to be resting. Relax."

He let out a labored breath as his body shuddered beneath her. She kissed his cheek and sat back up, moving her wrist up and down as she stroked him.

The sight was incredible, and for a moment, he didn't breathe. He watched as she squeezed him tightly, pumping her hand as she focused on rubbing her clit along his thigh. Her other hand held her skirt up, simultaneously dragging her hand up her torso and towards her breast. Her face was delicately twisted in pleasure, her eyes glued to the stiffness in her hand. Aang thought he was going to faint.

"This feels so fucking good, girl. You have no idea," he groaned, his breaths uneven as he felt himself grow harder with each pull of her wrist.

She smiled down at him, teasingly. "Only the best for the Avatar."

He rolled his eyes and stared at her clit, imagining himself grabbing her hips and pulling her against him more forcefully. Katara was starting to whimper, making him twitch in her palm. The hand that held her skirt went down to spread herself wider, allowing more nerves to find friction. He was gasping.

She looked at his pitiful state, secretly pleased with the intense reaction he gave her. She moved to straddle his hips before holding his length along her folds, continuing her grind against him. He watched as wet skin wrapped around the underside of his cock, easily gliding up and down, and desperately threw his head back into the pillows.

The medicine was blissful, but nothing compared to this. He whined as pleasure consumed him, feeling both tortured and euphoric from the way she was commanding him. He only knew that he needed release, and knew it was happening soon.

"Fucking hell, Katara- please."

"Aang," she sighed. His name leaving her lips like that nearly made him burst. "What is it?"

He didn't really know. He supposed he was being a little selfish. After all, she was the one seeking relief first, and he was merely grateful to be the vessel for that goal. Who was he to deny her? He bit his tongue and grit his teeth as his gaze went down to watch her as she slid along him. His tip was teasing her clit, the symphony of her whimpers and the sounds of fluid on skin causing his body to melt into the mattress. He couldn't help but lightly thrust against her, rationalizing that he was only trying to help.

"Aang, you're so hard, it feels so good on me." Her whimpers were turning into drawn out moans. "I've been so turned on, I've been using my fingers but- but- I just couldn't stop thinking of you." Her head lolled back. "I've wanted you so bad."

Her confessions dripped like syrup down his throat, sticky and sweet, a wave of bliss overcoming his senses. He could barely see or hear. Her words – her dirty words – danced atop his skin and burned into his hips. He could only imagine how he looked right now, and he loved it.

Through gasps of air Aang fought to speak his warning. "Babe, your pussy, it's- it's too much."

She giggled. "You're not even inside of me."

He glared. Did it matter?

"It's okay, I'm close, too. Look at how wet you've made me."

He followed her orders. He had previously made an effort to look away, the view too overwhelming, but she made sure his gaze never faltered now. "Look, baby, look at me." He saw himself pulse as she increased her pace, and fuck, he was going to cum soon.

Katara was grinning in pleasure, holding onto his length and using him to rise higher and higher. He couldn't believe he was seeing her like this. Her cries intensified, her pace desperate, and he knew she was reaching her peak. He felt his own climax rising, too, and thrust in an upwards rhythm.

"Aang, I'm gonna cum, soon." she breathed. "I want you inside me when I do."

There was no time to register her words as she positioned him outside her entrance and plunged down. Her fingers committed to a circling motion as her hips started to spasm. He was only halfway inside of her when he felt his release bubbling and spilling over.

"Fuck, Katara, fucking spirits-" He let out a stuttering groan as he jerked his hips up, Katara wailing and writhing as she desperately touched herself. She was clenching him as he released inside of her, crying out as her fluids drenched him.

"Aang," she groaned as pleasure waved through her. "I can feel you- oh, fuck, it's dripping out of me."

She was right. He watched as his release flowed out from his position inside her, both of them throbbing and sending more gobs of liquid down his length. The view was so erotic, his erection barely relaxed. They were both catching their breath and watching as she dripped onto his hips.

He groaned and she laughed as she pulled her hips off of him, more of his release falling onto him in a puddle. He took a moment to admire her while they allowed their bodies to settle.

She sat back on her hips, inspecting the mess they made. "I suppose it's time for a bath, now? I'll go with you, there's still more work to be done."

Maybe the ambush wasn't so bad.
