tip of my tongue (sweet and sour)

Summary:

She ran the tips of her fingers along it for a moment, and a brilliantly devilish idea popped into Agatha’s head at that moment.

Distracting her with another kiss, Agatha conjured a burst of her purple out of her fingertips and pressed on Rio’s bulge, imbuing it with her magic.

The reaction was instant; Rio suddenly felt the pressure of Agatha’s hand around her newfound appendage, and she gasped against her mouth.

Agatha’s grin grew wider as she experimentally rubbed over the bulge, then grasped it in her hand and squeezed.

Rio’s hips rocked forward in a jerky, uncontrolled movement. Her resounding hiss was sharp and she bit down on her bottom lip, hands tightening around Agatha’s waist.

“Fuck…”

Chapter 1: jealousy

Chapter Text

The ride back to Agatha's apartment was quiet, and not in a peaceful way.

 

Agatha sat with her arms crossed tightly across her chest, staring out the window as the city lights flickered past. Rio, ever composed, leaned back in her seat with one arm resting casually against the door, her expression calm but unreadable.

 

Agatha's mind raced, the memory of Rio and some woman at the bar replaying itself over and over again like a broken record.

 

They'd all been sitting together at a booth, laughing along as Billy told some ridiculous, likely made-up story, when Rio had offered to grab her and Agatha a second round of drinks.

 

She'd been gone a few minutes when Agatha spared a glance over at the bar, and she found a shorter, redheaded woman standing with Rio. Her mouth was spread into a big smile, mid-laughter, and she'd had the gall to reach over and brush her hand down Rio's arm in a flirty manner.

 

It took every single fibre of Agatha's restraint not to let her anger flare up and send a ball of purple-ish magic straight at the woman's head.

 

To her credit, after that bold move, Rio made a point of taking a step back and gesturing over to the table, saying something that couldn't be made out from where she sat. Agatha had turned back to the group, ignoring the resounding feeling that they were being stared at, until Rio came back with drinks in hand and easily slid into the seat beside her.

 

Safe to say, Agatha had dragged Rio out of the bar a couple minutes later, running off the anger building inside of her stomach at that woman's audacity.

 

Their driver pulled up to the curb outside their building, and she paid before stepping out and holding the door open for Agatha.

 

She muttered a quick thanks to the driver and closed the door behind her, following Rio's lead up the stairs to their apartment, keys jingling in her hand as she unlocked the door.

 

Once inside, Agatha kicked off her boots and headed straight for the kitchen. She needed something - anything - to distract her from the thoughts racing through her mind.

 

Twisting the cap off a water bottle, Agatha leaned back against a countertop as she watched Rio linger by the doorway. She was silent for a moment, before sidling up to Agatha in the kitchen and finally speaking.

 

"You've been quiet since we left."

 

Agatha took a sip of the water, back turned to Rio.

 

"I'm tired." She said curtly.

 

"Agatha."

 

"What?" Agatha snapped, finally turning around to face her.

 

Rio's arms were crossed, and she raised a brow at her wife. "You're upset.”

 

“I’m not upset.”

 

She narrowed her eyes slightly, tilting her head at Agatha in that maddeningly calm way of hers.

 

“You’re jealous.”

 

“Jealous?” Agatha let out a bitter laugh, but she immediately knew it was true. “Of what?”

 

“The girl at the bar.”

 

She felt her face flush, grip tightening around the water bottle. “I don’t know what you’re talking about.”

 

“Agatha…” Rio said again, softer this time.

 

“What do you want me to say, Rio?” Agatha snapped, the words tumbling out before she could stop them. Her eyes flashed purple with unkempt emotion, and the bottle in her hands disappeared from the pressure in a wisp of black smoke. “That I hated seeing you all up close and personal with her? That it made me feel like I didn’t even exist?”

 

“I wasn’t getting up close and personal with her.” She said firmly. “We were talking. That’s it.”

 

“You were laughing.” Agatha shot back. “She was touching your arm.”

 

“I didn’t ask her to do that, Agatha.” Rio’s voice rose slightly, her frustration evident now. “You really think I’d hit on some girl at a bar?”

 

“I don’t know!” Agatha threw her hands up, pacing in the small kitchen. “I don’t know what to think, okay? You’re gorgeous and charming and – you could have anyone, Rio. Anyone.”

 

At that, Rio’s expression softened. She stepped closer to comfort her wife, but Agatha held up a hand to stop her.

 

“Would you fuck her?”

 

“What?” Rio blinked, clearly caught off guard.

 

“The woman at the bar.” Agatha said, eyes locked onto Rio’s. “Would you fuck her?”

 

“No, Agatha. I wouldn’t.”

 

“Why not?”

 

“Because I don’t want her!” Rio’s voice was sharp now, patience wearing thin. “I only want you.”

 

“You mean that?”

 

“You’re my wife, I love you more than anything in the fucking world, Agatha.” She sighed, finally getting close enough to grab Agatha’s hands, her thumbs smoothing over her knuckles.

 

A breath hitched in the back of Agatha’s throat, and Rio noticed the switch in her demeanour. It shifted from frustration and overt jealousy to… desire? Lust?

 

She uncurled her fists and made a point of running her hands up Rio’s toned arms slowly, letting her gaze drop down to Rio’s lips in a teasing manner.

 

“Prove it.”

 

Before Rio could think too much about it, Agatha leaned forward and pulled her forward, their lips crashing into one another.

 

It was fierce and messy from the get-go, all teeth and desperation as hours of hidden, built-up tension came spilling out of Agatha in a torrent. She let out an involuntary whimper as Rio’s hands slid down to her waist, pulling her closer, and Agatha returned the favour by sliding her hands down Rio’s stomach.

 

Her head was spinning; from the stress, adrenaline, and the alcohol all at once - but Agatha didn’t care. She didn’t want to care about anything except the way Rio’s lips moved against hers, the way her hands gripped so firmly, so possessively .

 

“You’re mine.” Rio broke the kiss to say, her breathing heavy. “And I’m yours. Say it.”

 

Agatha shivered, her heart pounding in her chest. “You’re mine.”

 

Rio smiled, her lips finding Agatha’s again.

 

The kitchen felt heavy and thick with sex as Rio backed Agatha backward until her hips bumped against the counter. Without breaking the kiss, Rio lifted Agatha effortlessly, setting her down on the cool surface.

 

Agatha gasped, the sudden movement making her head spin even more. Rio’s hands slid up her thighs, gripping onto them as she stepped between Agatha’s legs.

 

“Do you believe me now?” Rio pulled back just enough to meet Agatha’s gaze, dark eyes searching hers.

 

“Yeah.” She whispered, nodding. “I believe you.”

 

“Good.”

 

Rio smiled, and leaned in to meet her in a slower, softer kiss. They were languid and took their time now, simply enjoying the feeling of one another as Agatha let her hands roam down Rio’s stomach.

 

Agatha huffed out a breath and let one hand drift even lower, palming Rio over her crotch. There, she found an unexpected bulge hiding beneath Rio’s jeans, and the feeling made her grin mischievously.

 

“You've been packing the whole night, baby?” She whispered, tilting her head as Rio’s eyes drifted down to where Agatha’s hand rested.

 

“I thought I might get to fuck you in the bar bathroom tonight.” Rio answered, and the sheer thought of it made Agatha’s thighs clench together briefly.

 

“So presumptuous of you…”

 

She ran the tips of her fingers along it for a moment, and a brilliantly devilish idea popped into Agatha’s head at that moment.

 

Distracting her with another kiss, Agatha conjured a burst of her purple out of her fingertips and pressed on Rio’s bulge, imbuing it with her magic.

 

The reaction was instant; Rio suddenly felt the pressure of Agatha’s hand around her newfound appendage, and she gasped against her mouth.

 

Agatha’s grin grew wider as she experimentally rubbed over the bulge, then grasped it in her hand and squeezed.

 

Rio’s hips rocked forward in a jerky, uncontrolled movement. Her resounding hiss was sharp and she bit down on her bottom lip, hands tightening around Agatha’s waist.

 

Fuck…

 

Agatha gave her a mocking pout, sliding her unoccupied hand up to the back of Rio’s neck to softly rub over the baby hairs in a soothing motion.

 

“That feel good, hon?”

 

When Rio nodded enthusiastically, Agatha pulled her hand away. Rio was about to groan in protest and reach for it, pulling it back to where she’d been touching her, but then Agatha began unbuckling her belt slowly.

 

“Shit… oh my- Agatha-”

 

Agatha shushed her, unzipping Rio’s jeans and sliding her hand down the waistband, intentionally staying above Rio’s boxers. She palmed her over the fabric of her boxers, and Rio’s answering moan could’ve made Agatha come on the spot.

 

“You’re so good to me, baby.” She cooed, rubbing Rio’s clothed cock agonisingly slowly. “Such a good girl…

 

“Agatha, please-”

 

“Please, what? Use your words.”

 

“Touch me. Touch me, please.” Rio groaned, grinding up against Agatha’s hand and bumping into the insole of her thighs.

 

Agatha let the moment linger, squeezing a final time, before evilly sliding her hand out of Rio’s pants. “Take me to the couch.”

 

She didn’t need to be told twice.

 

Rio’s hands were already gripping Agatha’s thighs, and she hoisted them around her waist to lift her up from the counter. Agatha pulled Rio in for a kiss as she walked them into the living room, subtly grinding her hips down against Rio’s as she moved.

 

She finally reached the couch, moving down to deposit Agatha onto it, and Agatha smiled as she urged Rio to crawl into the space between her legs, spreading them wide enough to accommodate her.

 

The only sounds in their apartment now were the soft moans and rustle of fabric escaping them both, and Agatha slid her tongue along Rio’s bottom lip as she moved a hand down to grip Rio’s ass over her jeans. She encouraged Rio to press her hips down, and Rio realised with startling clarity that Agatha was urging her to grind into her.

 

It felt overwhelmingly good when she followed suit, grinding her hips down against the rough denim of both of their jeans. Rio moaned more frequently against Agatha’s lips as her hips seemed to take on a mind of their own, thrusting faster against Agatha’s crotch and making her cock twitch in her pants.

 

“Ag-Agatha…” Rio groaned as if she were in pain, holding herself up with one hand at the side of her wife’s head. “You feel amazing… too good -”

 

The words were cut off by her own moan, as Agatha lifted her own hips up to press against Rio’s, rolling into them.

 

“You deserve it, sweetheart.” Agatha teased, trailing gentle kisses along Rio’s jawline and down to her neck. There, she sank her teeth into the pulse point of Rio’s neck and ran her warm tongue over the bite to soothe it.

 

Her hips stuttered at the mixture of Agatha’s appraisal and the feeling of her tongue and teeth against her neck. She ground down against Agatha faster now, running her free hand up her stomach and palming at her chest. 

 

Agatha smiled and thrust her chest out a little more to give Rio easier access. Their hips now moved in sync, with Agatha meeting Rio’s gradually increasing movements as she moaned louder into the crown of Agatha’s head.

 

Rio’s head wasn’t clear anymore. All she could think about was the feeling of her wife’s body beneath her, how good it felt to be slotted in between her legs, how amazing the feeling was to-

 

“Oh, shit."

 

“What’s wrong? Rio-”

 

Agatha pulled back just as Rio’s hips stuttered to a halt between her legs, and she let out a high-pitched moan, muffled as she buried her face into the softness of Agatha’s shirt.

 

She realised what was happening and smiled to herself, grinding up into Rio’s crotch and spurring her on. 

 

Rio’s entire body shook as she found herself being violently thrown into an orgasm, unexpected and thus catching her off-guard. She moaned and groaned dumbly into the fabric of Agatha’s shirt as she felt her cock twitch in her pants, shooting into her boxers and wetting them slightly. The feeling only grew more pleasurable and mortifying simultaneously as Agatha ground up into her sensitive cock, drawing the last bursts of arousal out of Rio until she stilled entirely.

 

Eventually, a sense of embarrassment crept up Rio’s neck.

 

She just came. In her pants.

 

And Agatha hadn’t even touched her.

 

Rio panted as she willed herself to sit up, leaning forward on her hand to face Agatha. Her cheeks burned with lingering mortification.

 

“I’m sorry, I didn’t… I wasn’t expecting that, I swear to-”

 

But Agatha simply interrupted her with a kiss, cupping Rio’s face and brushing a thumb over her cheekbones affectionately.

 

“That was so hot.” She mumbled against Rio’s lips, pressing another kiss to them. “I’m going to make you come so many times, you won’t be able to keep track.”

 

“Agatha…” Rio whimpered, huffing an exasperated breath into her mouth.

 

“My good girl. My wife.”

 

The affection hit Rio directly in the chest, and she couldn’t help but press a final kiss to Agatha’s lips, before manoeuvring herself away from Agatha’s spread legs and standing up on shaky legs. She outstretched a hand for her wife and smiled when she automatically took it.



“Lead the way, querida.”
