If you are taking Cophine prompts, you should totes write something where Cosima finds out that Delphine kissed Sarah and then "punishes" her with really great sex. Or like there one of them agrees to do something and the other promises to make it up to them (with really great sex).

Also just fyi I id totally upload the wrong chapter for chapter 6, though it was very kindly pointed out to me so I've now fixed that. Just in case any of you were like "this seems way too familiar", I'm not super unoriginal, I'm just dumb.

"No Delphine, no way." Cosima was shaking her head so furiously it could well have come loose. "There's not a snowballs chance in hell."

"Mon amour…" The whine in Delphine's voice managed to sound musical thanks to her accent.

"Seriously, no," Cosima insisted, putting all the emphasis on the last word.

Delphine inched closer to her on the bed. Cosima was sitting against the headboard, legs stretched out in front of her and her hands folded firmly across her back. Delphine straddled her legs, placing a palm on either side of the brunettes body so she could lean in towards her ear.

"S'il vous plait mon Cherie," she husked, her breath hot and wet against Cosima's skin. "Je vais faire quoi que ce soit."

Cosima had never been the best at languages in highschool. That said, she didn't really need to be to figure out what her girlfriend had just said to her.

"You'll do anything?" She quirked her brow, not that Delphine could see, as her head was still resting beside Cosima's ear.

"Anything…" Delphine's voice was thick with desire and that made her accent all the more apartment, which in turn sent a shiver down Cosima's spine.

"Shit…" Cosima whispered, feeling her throat go dry as Delphine's lips traced the shell of her ear.

"Is that a yes?" Delphine enquired hopefully, pulling back from her ear and looking down at her girlfriend.

"It's a maybe," Cosima corrected with a sly grin. "It's up to you to change my mind," she added, her arms snaking around Delphine's neck to pull their lips together.

She felt Delphine's lips move against her own and knew that meant her challenge had been accepted. The blonde's kisses were presence, with months of expertise guiding her mouth as if on auto-pilot. She knew just when to pull Cosima's lower lip between her teeth, and how to bite down until she felt Cosima's eager moan against her lips and the brunette's hands moving more frantically against her skin.

She let her teeth scrape the inside of Cosima's mouth as she pulled out of the kiss, instead planting softer kisses along her cheek; then her jaw; then eventually her lips found the corner where her jaw led down to her neck. She lingered here, again knowing just how to rake her teeth gently across the skin to cause Cosima to shiver, and just how to suck on her earlobe to produce a gratuitous groan.

Then her lips moved on, ghosting over the vast expanse of Cosima's neck. The brunette tilted her head eagerly to one side and Delphine licked at the creamy flesh, her mouth hovering over Cosima's pulse point for only a second before her lips descended on the sensitive area, not moving away until she was sure there'd be a bruise there by morning.

Once satisfied she continued on to Cosima's collarbones, nipping the skin with her teeth before soothing it with her tongue. She could feel the brunette wriggling beneath her, her chest rising and falling heavily as her arousal grew. She also heard the way Cosima groaned reluctantly when she pulled away from her skin, and the way she hummed approvingly when she realised this was only so Delphine could remove some of their restrictive layers.

Cosima's top was first, then Delphine's, then Cosima's bra. They lay messily on the otherwise clean floor, though neither woman seemed to care, especially when Delphine dipped her head again and this time her lips closed around Cosima's nipple.

Her tongue swirled in circles and Cosima arched into her mouth. Her teeth scraped at the erect nipple and Cosima hissed as her nails scratched a path up Delphine's back. Her free hand toyed with the brunette's other breast, palming it and rolling the nipple between her fingers until Cosima was panting with indescribable desire.

Cosima's hands couldn't keep still. In the same way they became more animated when she explained things they explored when she was aroused. They roamed the expanse of Delphine's soft skin, dipping into the groove at her waist and clawing along the bumps of her rib cage. They palmed at her breasts over the material of her bra, and traced the outline of her tight abdomen.

In the meantime Delphine's lips moved away from Cosima's breasts and began moving down her stomach. Her decent was agonisingly slow, as she paused at intervals to leave small love bites on the blank canvas of Cosima's flesh. As she done this one hand moved up the inside of Cosima's thigh, making quick work of removing her patterned leggings and underwear in one skilled movement.

She could feel the heat coming from Cosima's core even before her lips made it that far. She could sense the aching desire between her girlfriends legs as her lips kissed the brunette's hip bones. She could smell Cosima's sex as she trailed wet open mouth kisses along the inside of her thigh. She could practically taste it as her mouth hovered above Cosima's core and the brunette's lower body rose off the bed towards her.

When her mouth finally did close in around Cosima's clit it was almost as much of a release for Delphine as it was for the brunette. She relished at just how wet Cosima was for her, and she felt wetness pool between her own legs at the thought of what she was able to make the younger woman feel. Her tongue descended slowly through Cosima's folds, and pushed inside her just enough to make Cosima gasp and her hips buckle up reflexively. Then her tongue was gone again, and then it was back, circling around Cosima's bundle of nerves, drawing sharp gasps and longer moans as it worked.

Cosima made a muffled noise. Something that sounded vaguely in the realm of "more" and just like that she felt two of Delphine's fingers sliding inside her. No teasing, no games, just pure heavenly release as Delphine's tongue worked its magic and her fingers sank deeper and deeper into Cosima's core, curling expertly on the way back out as Cosima's entire lower body matched their rhythm.

Slow first, then faster, then faster again, until Delphine's arm was in agony and Cosima felt like her entire body was going to explode.

Then it did explode. Every muscle tensed up as her body suddenly stilled. Delphine's name slid off her tongue followed by a series of cusses and then just incoherent pants and sighs as her high ripped through her.

She wasn't sure how long the orgasm lasted, but when her back finally hit the mattress again, and enough strength returned for her to open her eyes Delphine was lying beside her, a smile wide across her features.

"As the French would say merde," Cosima sighed, her own grin showing off her pearly white teeth as she butchered the French pronunciation.

"I think you mean merde," Delphine corrected, rolling each letter of the word perfectly in her natural French lilt.

"Hey, do you want me to go with you to this family thing or not," Cosima scolded, smacking her girlfriend playfully on the arm.

"Does this mean you'll go with me?!" Delphine questioned, her eyes growing a little wider in excitement.

"I'd have probably gone anyway," Cosima replied with a casual shrug. "Saying no first was just way more fun though."

"Tu est tres effronté!" Delphine gasped, though she quickly broke down into giggles when Cosima's tongue poked out from between her teeth teasingly.

"Nah, I'm just a genius," she corrected, laughing when Delphine rolled her eyes and muttered something in French that Cosima's highschool level understanding couldn't quite catch.
