Kara had been renting Jason’s spare room for almost six months, and they both agreed it was the best house share either of them had lived in. They divided chores equally, they enjoyed each other’s company but also gave each other space, and their friends were mostly mutual so parties were guaranteed successes. Both of them could cook, and they liked most of the same TV shows. As several of their friends noted, it appeared they had a successful but completely platonic marriage.

There was just one complication: Kara loved getting fucked while she was asleep, and had given Jason perpetual consent to oblige her.

They’d set the rules one night shortly after it had happened for the first time, Jason’s guilty conscience forcing him to confront the situation. He knew she’d enjoyed it, but he couldn’t shake the feeling he’d taken advantage of her.

She’d laughed out loud. “Taken advantage? Sweetheart, I passed out half-naked with my door open immediately after wanking with the loudest vibrator I could find.”

Jason thought back to that night - finding her asleep on her bed, legs open, dress hitched up for easy access.

“You.. baited me?”

“When a girl has certain… interests,” Kara explained, “She has to ensure she’s in control of the situation.”

The rules were simple: if Kara went to sleep with her door open and her light on, she was fair game. To keep things interesting, Jason didn’t indulge himself every time he had the chance.

And Jason mixed things up, so Kara never knew for sure what she was going to wake up to. Sometimes he would simply get her off in her sleep, so Kara would come to soaking wet but still wearing underwear. On other mornings, she’d wake up with Jason’s cum all over her thighs.

One night after hours of drinking, Jason’s best friend Mark asked what all of their friends were thinking:

“So,” Mark continued. “You live with this girl, you have all the same friends, you have a laugh together, and - technically - you’re fucking. And she’s not your girlfriend because…?”

“It’s a long story.”

It was not, in fact, a long story. Kara enjoyed Jason’s company, and was very happy that he was understanding of her kink, but she knew having a boyfriend would impose on her ability to indulge it. Put simply, they liked fucking each other but also wanted to be able to fuck other people and talk about it.

The bar called last orders, the lights came up, and Jason and Mark found themselves drunk and aimless. As tends to be the case with such evenings, their next move was decided by a simple question from Mark:

“You got weed?”

“At home, yeah.”

“Your place it is, then.”

It was well past midnight when Jason drunkenly jammed the key into his front door and opened it to a dark, silent house.

“Make yourself comfortable,” he told Mark. “I’ll go grab my stash.”

Halfway up the stairs, he saw that Kara’s light was on. Immediately, the thought entered his head: “Please let the door be open.” He was surprised at himself for feeling so desperate.

Sure enough, the bedroom door was wide open. Jason couldn’t afford to get distracted with Mark downstairs, and didn’t look in as he walked past.

If he had, he’d have seen Kara wide awake and fully clothed, reading a book. She’d heard him struggling with the lock, and wanted to mess with him. As Jason passed by again and headed straight downstairs she sighed, disappointed, and got up to close the door.

“Managed not to accidentally fuck your housemate again then?”

Mark. Kara had only met Mark once, but he’d made quite the impression. He had a cheeky confidence that was both infuriating and hugely attractive, and Kara had made no secret of the fact she wanted to see him again. She picked up her phone and texted Jason.

Is that Mark I can hear?

-Yeah, sorry. Promise we’ll be quiet.

You’re always quiet ;) Don’t know about Mark though. 
Yet.

Kara undressed and got into bed. She left the door open.

Jason and Mark had been smoking on and off for two hours. The lethargic calm of the weed had mixed with the alcohol to turn them into schoolboys, teasing each other incessantly as they lay glued to the couch.

“Admit it,” Mark was saying. “The reason you and Kara aren’t a couple is because she wants to fuck around.”

“Maybe I want to fuck around too!”

“And maybe I want a ten-inch dick that triggers orgasms on contact, but it isn’t going to happen.”

“Ok. Then answer me this. If my arrangement with Kara wsn’t mutual,” Jason turned to his friend and adopted the smug face of someone who knows they’re about to have a mic-drop moment.

“Would I know that she wants to bang you?”

Mark was silent. Jason laughed.

“I told you, it’s just a thing.”

Mark’s tone changed. He sounded curious, almost child-like.

“What’s it like?”

Jason looked confused. “Eh?”

“With Kara.”

Jason said nothing, he just smiled.

“That good huh?” Mark sighed.

Jason stood up, unsteady from the drink and smoking, and opened the door through to the staircase.

“Do you want to see for yourself?”

Kara had been asleep for well over an hour. The shameless position she’d adopted - on her front, naked, with a pillow pushing her hips up - had transformed into something a little less sexy as her arms and legs had spread out in her sleep. It looked more like she’d been thrown into the pillow than delicately laid down on it, but its primary function - to display her pert ass and silky smooth pussy - remained served.

Mark stared at the vision in front of him. Kara’s soft, naked body, facing away from him. Her breasts pressed out underneath her, her ass elevated by the pillow.

“You lucky fucker,” Mark whispered. Jason quietly walked towards the bed and sat on Kara’s right side. He looked Mark in the eye and softly stroked the skin on the back of Kara’s leg, slowly moving his fingers down towards her thigh. Mark’s mouth was hanging open, his face a picture of envy.

“Don’t just stand there them,” Jason whispered. He waved Mark in, beckoning him to sit on Kara’s left. Mark gently lowered himself facing Kara’s body, following her raised legs to the tidy, puffy pussy poking out from between them.

He put his hand on her skin, just above her knee, so his fingers rested on the sensitive skin of her inner thigh. Jason was doing the same, slowly stroking as he moved his hand towards her ass.

“Now the trick,” Jason whispered, “Is to make sure she’s already wet before you touch her properly..

He winked. “It doesn’t take long. Just copy me.”

Jason moved his fingers in light circles, brushing Kara’s skin with his fingertips. Mark did the same, and almost immediately Kata’s legs opened further, allowing the boys’ fingers to brush over her soft, smooth labia. With four hands on her body, it wasn’t long until their fingers were wet with her arousal.

“And now,” Jason whispered, “Her clit.”

“Anti-clockwise, and keep the rhythm,’ he said, as Mark slipped his hand under the pillow. His finger found her swollen button and started stroking it. He couldn’t believe how still she was. As he kept the steady pressure on her clit, her breaths started to become sharp and shallow.

“When her breathing changes, she’s about to cum. But to push her over the edge, well…” Jason ran his fingers over Kara’s slick, wet pussy until they were lubricated. He very lightly pressed between the lips, and his finger slipped inside her to massage her g-spot.

Mark, still working her clit - his hand now soaked underneath her - was spellbound. He could tell from the way Kara’s body was shaking that she was about to orgasm, yet her face still looked blissfully at rest.

“Now, by the way, would be the time.” Whispered Jason. As he spoke, he was unbuckling his jeans.

“You can’t be serious.”

“I know it might seem weird but I’m telling you, it’s worth it.”

“And she’s definitely into it?”

Jason smiled a wide, Cheshire-cat grin.

“It’s her thing. She loves it.”

Kara let out a quiet whimper as her body tensed in the middle, then relaxed, shaking all over. Mark pulled his hand away - and put it to his lips, tasting Kara.

He nervously unbuttoned his shorts and kicked them away, then kneeled behind Kara’s elevated ass. She looked so tempting. And so wet. Surely she was just pretending, he thought.

She yawned and stretched her body, briefly opening her legs further and opening her pussy. Mark felt an impulse take over. He pulled his semi-hard cock out of his boxers and pressed it against Kara’s opening. She coated him immediately, and he used her own fluids as lube to stroke himself against her until he was fully hard, noting how she was wetter each time.

Finally, as he went to tease her one last time, her body opened to him and he found himself inside her, almost up to the hilt. He heard her breathing change as he pushed himself deeper into her, until she contained all of him, and gently started to slide in and out of her.

She was so wet it was easy, and he soon found himself fucking her deeply, convinced she’d wake up. But she seemed to remain fast asleep.

Jsdon decided to try his luck. Sitting with his legs either side of Kara’s head, he pulled off his boxers and slowly pushed his erect cock towards Kara’s mouth.

Kara’s mouth opened as she gasped for breath, approaching another orgasm. Jason slowly pushed the tip of his cock through her lips and onto her tongue. She closed her mouth around him, giving him that blissful feeling of his dick resting on her tongue and her breath on his skin. But she didn’t move.

Jason carefully, almost imperceptibly, moved his hips back and forth. Starting to fuck Kara’s mouth. He pushed himself deeper, to the back of her throat. She choked, loudly, and Mark quickly pulled out as her eyes bolted open.

Kara reached for her mouth, finding Jason’s cock and pulling it out as she gagged on it.

“Not when I’m asleep,” she said, firmly. “Sorry.” She kissed the swollen tip.. But she was also aware of another feeling - or the absence thereof. Like she’d been full.

“You can go back to fucking me though.”

Kara felt the cock inside her before she’d finished speaking. Jason saw the shock on her face before she looked over her shoulder.

Mark was kneeling between Kara’s legs, guiding his erection inside her, when her eyes met his. He froze instantly.

“It was Jason’s idea,” he mumbled. “He said -”

“That I wanted to fuck you, I heard.” Kara giggled. She squeezed her pelvic muscles and gripped the head of Mark’s cock. As she pulled it tight she could feel its coarse texture, and the sensation of a ridge - almost sharp - pushing into her.

“Fuck.” Mark groaned. He let go of himself and put his hands on Kara’s ass to keep himself upright as she pulled his length inside and began to slide up and down it. The shape of his cock was stimulating her g-spot in a way she’d never experienced.

“I’ve never been with a circumcised guy before,” Kara said. “I like it.”

Jason was still kneeling in front of her.

“Thanks for sharing.” She looked into his eyes, and slowly took his entire length into the back of her throat until her lips were pressed against the base of his cock. She moved her tongue back and forth over the tip until he started to tremble, then lifted her hands and gently stroked his balls.

“Holy shit, Kara. I’m so close…”

But Kara was now busy grinding back against Mark, feeling him grow inside her. The shape of his head was so pronounced, and she knew he must be about to finish.

She let Jason’s cock fall from her mouth and looked over her shoulder to see Mark’s face, tensed up as he tried to hold off his climax. She chided him jokingly.

“Did you prefer it when I was asleep?”

“No… I just…”

“You know I can feel you’re about to cum. So just…”

Kara deployed her special move. She clenched her pussy lips around the tip of Mark’s cock, squeezed hard, then slid down him. Mark cried out as he lost control.

“Fuck, I’m c-”

Kara pushed back so hard that Mark lost his balance. She felt his whole shaft throb before it slipped out of her with a wet popping sound. But Mark’s grip on her was so tight that he pulled her down with him.

Kara fell straight into Mark. Her ass landed between his legs but her body was pressed against his. She could feel his cock twitching, smearing her back with his load.

“Don’t want you messing up my bedsheets,” she laughed. “Now boys, I really must get my beauty sleep. Thank you for your…” she put her finger to her lip, where a tiny bit of Jason’s cum had stuck. She picked it off and wiped it onto his leg. “Your contribution.”

She closed the door behind them and turned out the light.
