Synopsis: Krissi pays a visit to her younger sister.

Note: This story is a sequel to, “With Friends like Cassandra...”

Cynthia eyed Kristen with playful suspicion as they dined on surf and turf at a little local seafood place she knew. The lobster came from an hour and a half away and the chef knew how cook a steak so juicy a butter knife could slide right through it and tonight, the place maintained its reputation. Truthfully, she was happy to have the excuse of treating her sister to come here, and happy to see her at all.

Oh, she knew they didn’t have the kind of relationship where they had to talk to each other three times a week to feel complete or anything; an hour or two every two or three months was enough. They were both busy people who put work before most else. They’d relax when they reached a comfortable plateau when it came to salary, position, and respect in their fields. Once they hit their ‘cruising altitude,’ as Kristen called it, they’d focus on a husband and all the rest of the things that made for a well-rounded life.

Kristen had her city planning job and Cynthia was two or three years from associate partner at her accounting firm, maybe a little less if Wayne was still one of the men making the call, as he’d stare at her chest while talking to her at least a good third of the time. When she knew she’d be working with him she made a point of unleashing the girls just a little with an extra button undone or, occasionally lean his way to give him an opportunity for a quick glance. Her skills were impeccable and she knew it. What’s more, she knew he knew it when he put her in the lead of more than one project. If, when the time came, ‘the girls’ put her over the top, then, great.

They were each focused and driven enough that it’d be every two years or so before their conversations inevitably led one of them to comment on how long it’d been since they’d seen each other. Then it would hit them how much they missed spending time together, then one of them would make the trip to the other to catch and just spend time together. It was getting to be about that time, so when Kristen suggested coming for a visit Kristen had already been almost absent-mindedly blocking time out over the next few months to make room for a visit no matter who did the traveling, so, when Kristen called, Cynthia was more than happy to pick her up at the airport and take them straight to dinner.

It was nice to have a chance to catch up and almost immediately Cynthia knew there was quite a bit to catch up on and Kristen was different. Neither of them were so uptight that people couldn’t deal with them or they couldn’t deal with them, but they were both driven and focused. Tonight though, Kristen was visibly more relaxed than Cynthia had ever seen her without a few glasses of Merlot first. And that wasn’t the only change she needed to know about. “So what’s up, Kris?”

She tried not to smile, almost as if she already knew what it was all about, “What makes you think something’s up?”

Cynthia snickered as she swallowed a buttery bit of lobster. “Wanna list?”

“Why not, Miss Smarty? People talk over dinner, so why skip over things to talk about?”

“Well, you seem a shit ton more relaxed than the last time I saw you. Things must be going great at work.”

“Everything at home is going great; never better, really.” With the smile came an unmistakable blush. “And this is a nice little vacation for me, so, no, I’m not thinking about work for once in my life. Can I have an actual vacation for a few days, little sister?”

Her fork dropped to the table and she mirrored the blush. “I knew it. Who’s the guy, Kris?” She leaned conspiratorially forward, “Dish, dish, dish.”

Kristen leaned forward too, still not able to fully wipe the teasing, coquettish smile off her face. “What makes you think there’s a guy?”

“Hmm... let’s see, there’s the makeup, which is more than you used to wear, which suggests there’s someone who likes to see you in it. You seem pretty relaxed to me, which means you’re either on anti-anxiety meds and they’re doing great for you or there’s a guy keeping you mellow. And there’s the fact that they’re floating free and I can’t remember the last time outside of a beach where you weren’t wearing a bra, which means you got into that because somebody likes seeing those things out.”

Kris rolled her eyes, “Like you don’t let your big girls roam free.”

Cynthia conceded the point with a guilty smile, “I do, but not just because. Usually it’s for the greater good: free drinks, reel in a client, and all that, but I’m not all into free-roaming pokies just to have them out.” She waved it off, Anyway, you’re dodging the question, so, who is the guy?”

“What makes you think there’s a guy?

Her head dipped and her eyes bugged just a little, “A girl? Shit, Kris, don’t tell mom and dad. You know they’re live and let live for other people but their girls better find men and give them grandkids.”

“That could still happen because,” she began, looking up at the ceiling, drawing out the tease because there’s also a guy.”

Cynthia stopped eating for fear that she’d choke on her food, “You. Are. Kidding me.”

Kris beamed, “Nah. A friend of mine from work introduced me to her boyfriend. She and I already were getting along because friend from work and he’s a great guy. They live open and one thing led to another and...”

Cynthia stared in disbelief, “Holy shit, Kris, I didn’t think you had it in you.”

Kris snickered, her eyes sparkling, “Now I get in in me plenty.”

They laughed together at the shared dirty secret, “Well, definitely keep that part from mom and dad. Seriously. You know as well as I do that they’d lose it. Make sure you only bring him him around and she’s just a friend that lives with you for whyever you can think of.”

“No wonder she hadn’t heard from you and started nagging me about whether or not I’d heard from you lately. When I told her you were coming this weekend she made me promise to have you call her.”

Another few bites between them and Cynthia shook her head in wonder before another giggle, “And no wonder you’re all loosened up.”

* * *

With a quiet dinner finished, Cynthia drove them back to her beach house. Opening the doors on the expansive living room done in warm browns that adjoined a kitchen done with all burnished silver appliances and black granite counter tops. The entire home was befitting of someone being where she was in the world. She tossed her purse and keys on top of the breakfast bar, “I assume you still know where the guest bathroom and things are?”

“Sure, Kris answered, “unless you changed stuff around a lot since last time.”

Cynthia undid the belt of her slacks and kept it with her as she slipped off her shoes and carried those, too with a smile in her voice “Does it look like I move things around a lot?”

“No, it has the usual, ‘I’m not getting laid so I’ll spend my time cleaning and organizing’ look to it that it always does.”

The smile was still in her tone, “We can’t all just fall ass-backwards into live-in threesome, can we? Wanna let me take a shower, then we can just be lazy in front of the TV for a while before I turn in? You didn’t give me much notice, so I have things I have to get done tomorrow, but Saturday and Sunday we can do whatever.”

“Sounds like a plan to me.”

Kris waited until Cynthia was down the hall, the master bathroom’s door was closed, and the water running before she lifted her small suitcase to the distressed leather couch and unzipped the bag. Digging under the icky and uncomfortable ‘Kristen’ clothes that she packed, she got the pair of Cube-y personal assistants out from under a couple of Old Krissi’s blouses. The little gray cubes that fit in the palm of her hand were exactly where she put them, and the cords, too.

Now’s the hard part. So many stupid steps and I can’t fuck up. I promised my sweet, sweet Teddy that I wouldn’t fuck up. He’ll be so sad at me if I do and I can’t make Teddy be sad. He even wrote down all the instructions for her so she them with her.

The easiest part was plugging the cords into the cubes. “Okay,” she muttered to herself, “She gets one and I get one.” No, that part’s the easiest part.

One in her room and she plugged it in. “Okay, turn on.”

She ran across the hall to her sister’s room, finding a free outlet just to the right of the nightstand. She plugged it in, turned it on, and held the power button like the paper...like Teddy...told her to. It was easier and less scary to think of it as doing what Teddy told her to instead of, like ‘reading,’ or ‘following directions.’ “Turn on, hold power button until blue light next to red light flashes. Go to other Cube-y”

“Yes, Teddy, my lovey,” she whispered dreamily as if he were there before she scolded herself. Use your brain, you silly bitch.

She scampered back to her nightstand. “Hold power button until blue light stops flashing and Cube-y says...”

“Connected.”

Yay. So yay.

Following the last instructions, she checked the Cube-y app to make sure it saw them both and to make sure which one was which. She was pleased with herself for doing it right and went back to the living room to grab her suitcase. The water stopped and her heart jumped when she realized that she left the Cube-y on Cynthia’s bed.

She took her suitcase horizontally in both hands, not bothering to try to zip it as she jogged to her room before setting it down and kicking it beyond the doorway. She went into Cynthia’s room and placed the Cube-y under the head of the bed as far as her arm could reach and her heart didn’t slow down until she closed the door behind her.

Krissi kicked off her shoes, tossed them in her room, and closed that door, too, before taking her phone and plopping herself back on the couch with it, knowing with that page -boy haircut of hers, she didn’t have to linger after a shower very long.

The next two hours were a relief and a torture for her. It was a relief because they just talked about simple things, little things, and nothing that Krissi had to work too hard to sound like Kristen would have in answering. On top of that, Cynthia was in a mood to relax, so all she really felt like having on as they talked were cartoons; honest, old-fashioned, golden age, smart talking animal versus stupid hunter, cartoons. They actually made talking like Kristen would feel a little less like biting her own fingers off.

The torture was looking at Cynthia, or, more rightly, trying not to. She just wrapped the thick purple robe around herself without tying it off, so, when she laughed or moved it would fall open a little, or more than a little, still without exposing everything. What did show was more than enough for a thirsty bi-girl. Every once in a while, some of that firm, lush left breast would peek out and the purple contoured over the flesh would only remind Krissi of how large it was. While hers sat nicely even as they hung a bit, Cynthia’s defied gravity without trying to the point where more than one person refused to believe they were natural, though they were.

Then there was every so often Cynthia propping a foot against the coffee table out of boredom, showing ample thigh while she was at it. Krissi had to will herself not to stare too long or being caught doing it. The cartoons helped there, too, letting her mind float away with the bright colors and funny voices, until talking to Cynthia led her to glance that way again. It was bittersweet agony until about midnight when Cynthia looked at the clock on the wall. “You’re on vacation, but I have to work tomorrow, so bedtime for me. You must be exhausted, too.”

“Not too bad. I’m just gonna sleep in, take a shower whenever I get up and then figure out the weekend.”

“Sounds like a nice day to me.” She got up from the couch and stood in front of her, robe now open enough to draw a thin line between those peaks, down that belly that had a hint of natural softness to it that hung on no matter how much she worked out that she let be because there was no considering herself fat, and the darker shadow caused by that fine down triangle. She extended both arms with a sisterly, “Bring it, Kris”

She swallowed as she got up, instantly feeling her sister’s arms wrap her in a bear hug. Krissi was so glad that there was her t-shirt and Cynthia’s robe that kept her from feeling Kris’s nipples hard against her. She returned the hug, reminding herself at the last moment to keep her arms outside the robe, settling them around her waist, settling instead for inhaling the apple scent of her hair.

“It’s great to see you. We really need to do it more.”

Mmm...do it more. Krissi kept herself from saying it, choosing instead, what Kris would say. “Don’t we always say that?”

“Because it’s always true.” She added a peck on the cheek for good measure. “G’night, hon. See you tomorrow. If you still like to dance, there’s a new club we can hit up if you want.”

There was a some thought. “I still like dancing, so that might be fun. ’Night, little sister.”

* * *

As soon as Krissi closed her door, she groaned as she shed the weight of even being ‘Kris.’ It was soooo fucking exhausting trying to remember what Kristen would say and how she would say it. Just thinking about that uptight bitch was too much. Then she had to remember all the big words that Kris knew and string them up so that Cynthia wouldn’t know anything was weird when that was the last thing she ever wanted to do again. ‘Kristen’ was complicated. Krissi wasn’t.

And with her sister in bed and Krissi’s door locked, Krissi thrilled at being free. She peeled off those pants that prudes wore that covered up all of her legs and kept her away from her pussy, which was wet now at the prospect of liberation and she giggled at the feeling, thinking of that part of her as something with a mind of its own That was sort of true because its need was already making her crazy. I know, kitty. I’m sorry. I didn’t get to fucking play with you all day. She couldn’t remember the last time she’d gone more than a few hours without it getting fucked by something or someone.

The only thing tolerable was the shirt. She would have liked to show some sexy belly around but stupid Cynthia would have asked questions. The shirt felt okay though because anybody that wanted to look could still have seen her tits. They looked, too. She thought of how they looked at her as she fished under her clothes to her toys, pulling out a latex dildo. She gave it a kiss, happy to see it before she hopped on to bed, so anxious to get something in there, she stood on her left knee, her right foot, planted firmly on the bed to spread her and give her height as she plunged it deep, thinking of all the men and women who looked at them at the airport, on the plane, and here in town.

Some glanced. Some stared, and a couple of the men almost drooled as much as her cunt was drooling right now. It was all she could do not to lift her shirt in front of them and just let them go at it, with whatever touching, kneading, slapping, biting, or titty fucking they wanted to do. They were real men like her sweet, sweet Teddy. They knew what they wanted and they knew what girls were for. She imagined one of the shoving his cock between her tits and did the same with her toy timing the wet, sucking sounds to the rhythm of her imagined lover. Slow and easy or hard and fast. Whatever worked for him. He didn’t have to care about how she felt. She was just there to make him happy and help him shoot the most cum.

The thought of seed from their cocks arcing all over her face, neck, and titties, coating them, made her eyes roll back in her head with a low moan and Krissi fell back onto the bed, body quaking, legs convulsing as though she were trying to climb the bed. She felt so good. That cum needed out so bad, but she knew there were more because the dirty thoughts wouldn’t stop. She ravenously licked the toy clean and the scent and taste filled her mind with the other torture of the day. Plunging it back inside and working is in a long, slow, twisting motion, she gave the thoughts whispered voice. “Fucking tease sister. Robe open like you want me to look at your big fuckin’ torpedo titties because you don’t fuckin’ care if I look or not.”

Cynthia was hot. She was so hot. Ask the uptight bitch that Krissi used to be and she would have said sure, but that was it. She’d notice, but that was it. Kristen would never think she was hot and want to do something about it. Kristen’s brain would never have thought about Cynthia’s body built to fuck while her cunt slobbered over it while she pounded it with a fake Teddy.

After Teddy and Candi talked to her, she loved all girls. The hot ones were hot. When she fucked them for movies or just for money to buy the things Teddy wanted it was awesome. Fucking the guys and girls that weren’t hot made Krissi even wetter because it was just nastier and that made her kitty purr. She wasn’t doing them because they were sexy, she was doing them just for money for Teddy, or the movies, the camming, or just because they wanted her and knew how to treat her.

And Krissi’s pussy was sure purring now. Even if Teddy hadn’t told Krissi to want her sister, she’d already want her because Cynthia was pretty and Krissi loved girls now. Krissi wanted her even more because there wasn’t much nastier to do than fucking your sister. If Teddy hadn’t told Krissi to go get her, she still would have wanted to do it because her sister was pretty and Teddy would have loved her.

But Teddy wanted her and Teddy sent Krissi, and now Krissi was thinking of apples and pussy. She sucked the toy into her mouth tasting every bit of pussy cream off the toy and, with two quick rubs of fingers to her clit, her face twisted and her back arched as another cum made her every muscle lock. She could never have cum like this before Teddy. Everything was better for her because of Teddy. Eyes closed, she kissed the cock, I love my Teddy more than anything. She dipped it back in while she waited for Cynthia to go to sleep.

* * *

Krissi was finally relaxed after an hour and a dozen cums just as beautiful, bursting pink in her brain as the first two as she picked her phone up from next to her and just to the right of the spent dildo and called up the app. She felt so much better after good cums. Krissi even felt a little smarter in those times before the urges came back. It helped that she was by herself with no cocks or pussies to distract her.

Hard cocks full of cum and juicy, wet pussies.

She scolded herself as Teddy would have while shaking her head free of the thoughts. Pay attention, you stupid bitch. Finding some bit of focus again, she made sure each Cube-y’s volume was all the way down right after she turned them on and slowly, patiently worked the volume up on each one as she spoke to them. She remembered all the things Teddy wanted her to say without looking at the paper because they were dirty things and her brain was great with dirty things now.

At “2” on the volume meter, she spoke. “Stay asleep, but listen, Cyndi.”

“Stay asleep, but listen to the pink and to Krissi , Cyndi.”

At “5,” she could begin to hear the pink noise in her own ears and it was such a sweet sound. It tickled her brain in all the best ways. Sometimes she could have it on for hours at home and just float on it. Sometimes she played with herself while she floated on it, and when she came doing that, she felt a little dumber and that just made her a lot wetter.

Krissi thought about what she was doing and that made her wet again. The first two fingers of her right hand found her clit and worked it lazily. She worked the volume up slowly, knowing it was going to take all night and she sort of wanted it to so she could enjoy it. “10”, then, “15,” then “20,” and with each step up she would wait long enough to be certain that her sister hadn’t woken up. “Stay asleep, but listen to Krissi and the pink, Cyndi.”

At “30,” Krissi grunted as her thighs locked and then quivered in surrender and another orgasm flowed through her. Krissi notched up the volume, waited, then spoke. Over and over again until it was at “100” She let it rest there, loving how it felt and loving even more to imagine a dreamy Cyndi. Cyndi dreaming of the pink and helpless against the pink. It hurt Krissi when she changed because her stupid smart brain tried to stay smart no matter what, but Cyndi’s brain was just in pink, her smart brain starting out asleep and not having a chance to get in the way to begin with.

That, with the pink, helped to keep her pink sopping wet. “Stay asleep, but listen to Krissi and the pink, Cyndi. Are you listening?”

“Yes, I’m listening to Krissi and the pink.” she heard, the words garbled and slow, as if they were struggling mightily to get from her brain to her lips and only making it a piece at a time.

Her body squirmed again as she rode another orgasm. She tried to stay focused, but, hearing her say those words was almost as good as Teddy’s cock or Candi’s tongue.

Cyndi was listening and Krissi knew exactly what to say.

* * *

Cynthia was exhilarated at the prospect of work when she woke up. It was a Friday, and her sister was here, so it promised to be a fun weekend, even if they just ended up going out to eat, then bringing dessert home so they could binge movies or cartoons until three in the morning. She had some paperwork to push through, but it wasn’t much beyond analyzing some income statements as a second opinion for a newbie. It wasn’t hard, and the only reason she thought she’d have to put much extra effort into it was that it wouldn’t do to make a newbie mistake herself. It was just going to be time consuming to redo the other’s analysis just to make sure everything was right before she added her own thoughts.

At least that was the plan. She got into work early and got settled into her office with her iced latte at 9:02, ready to bang out what she needed to and maybe bail early. At 9:05 the irresistible force of her will and her skill met the suddenly immovable object of the work before her.

And the wall won.

Cynthia just wasn’t getting it. What was so simple before that she could do almost in her sleep was an almost incomprehensible jumble of the foreign language of the words and the meaningless jumble of numbers. She could latch on to things for just a moment now and then, but she confused herself almost as quickly. Okay...okay...income is money I made. ‘Sales’ is money. ‘Op-er-a-ting income’ is money, too. It’s money I made. No? Yeah. ‘Income before ex-pen-ses’ is money I made, too. Why aren’t all these numbers added up to one big number so I can have lots of money?

She decided she must be more tired than she thought, so she’d take a break and try again in a few minutes. Cynthia headed to the bathroom for the added privacy and it was nice. It was quiet except for the sound of the fan overhead, but the noise was comforting and helped her find herself again. Christ, Cynthia. Get your shit together, she scolded, splashing water on her face that was as cold as she could get it before she checked her eyes and her throat thinking maybe she was coming down with something.

Beginning to feel better, she focused on her breathing while she listened to the fan hum away. She didn’t know how long she’d been doing that but she jumped when she heard a knock on the door from...Janey. “Everything okay in there?”

She cleared her throat, reaching for a paper towel to dry her face, finding it almost entirely dry already. “Yeah. Sorry.” She was feeling better, so she headed out with another, “Sorry.” as she walked back to her office without waiting for a reply. Okay. That was weird and stupid. Time to get back to work.

She sat down and got back to work for all of thirty seconds before it got tangled into her brain again, deciding that maybe if she talked it out she could make sense of it better. “Gross...what?”

Using your brain is too hard.

Why am I counting expenses for? Expenses takes away from my money. Why would I want to take away from my money? But I have to to get this right. Right?

Using your brain is too hard.

She stared at it, chin resting in her hand, trying to will it to be right. Using your brain is too hard.

She muttered to herself in response, “No shit, huh?” She looked at the time and after nine had become after one and she had no idea how. It seemed like she’d only got stuck in the jumble of numbers a minute ago and it was pretty clear that there was only one way out: agreeing that, just this minute, using her brain was just too fucking hard.

Deciding that she must be coming down with something after all and, feeling better once she decided to give up on the numbers and go home, she had enough of herself back to get Barry to do that little bit of work to help out the new guy. When she leaned in to do the asking she could have sworn she saw him glance down her top, which gave her a naughty rush. She let the girls sway left and right just a little bit to give him an extra thank you for helping her out. The girls waving goodbye. made her grin.

The routine of driving the road made things easier and she was back to feeling like herself when she got home. She started dropping her things along the breakfast bar as usual. “Hey, Kris!” She headed down the hall, not all that concerned about it, thinking she probably was either still asleep or went out. She gave the door to the guest bedroom a couple of knocks before poking her head in to check.

She was still asleep and Cynthia realized she hadn’t even made it under the covers, instead having passed out on top of them, still breathing slowly and deeply, her face a picture of peace and contentment. She was stretched out on the bed, left leg bent so that the heel touched the right. Toys were strewn all over the bed and around it like they were half of what she packed, the suitcase opened and clothes hanging over the edges like she was in a mad rush to find this or that.

Cynthia looked at that long form on the bed. Girls are so fucking hot. Pussies are so fucking hot.

The shame hit her like a fist to the face and she even turned down and away at the impact that came with knowing she was looking at her sister like that. It was so sick and dirty.

Girls are so fucking hot. Pussies are so fucking hot. Sick and dirty is so fucking hot. Shame is so fucking hot

Her eyes pulled her back to that body; that firm tummy and those silky legs. Her eyes pulled her head back to that slit that was still covered in dried cream from a night of relentless self-abuse.

Girls are so fucking hot. Pussies are so fucking hot. Sick and dirty is so fucking hot. Shame is so fucking hot.

Cynthia’s pussy was so fucking hot despite the nastiness and revulsion that went with look at her sister fucking naked, or maybe because of it, that she shut the door, paying no attention to the fact that she all but slammed it and did the same to the door to her room. Girls are so fucking hot. Pussies are so fucking hot. Sick and dirty is so fucking hot. Shame is so fucking hot.

Her pussy was screaming for attention through the pink fog settling into her brain, as even thinking seemed too hard today. She hadn’t gotten laid in too long, way too long, Cynthia told herself. That had to be it. She hadn’t even jilled in the shower in, she realized, a week and a half. I’m just seriously pent-up here. I’ll work this out and it’ll be fine. Her clothes came off in a flurry, feeling oddly more and less needy being nude. Cynthia was definitely more comfortable without all those stuffy clothes, but even her own body was reminding her that girls were fucking hot, with her nearly dripping pussy anxious to agree.

She grabbed her laptop from the corner desk intent on driving the really nasty thoughts away in favor of ones slightly less. Her fingers punched the keys with urgency and auto-complete took her to her go-to scenes at her go-to site and, where yesterday she knew she could have let her fingers take her clit dancing and cum in a matter of moments, she knew things were different now. Her brow furrowed because it just wasn’t working. There was her favorite bit of cockmeat holding a hot little auburn-haired thing by one ankle while she mewed wide-eyed as he plowed. The girl? The girl was always fine, but she never saw how truly hot she was. Sexy. Hot.

Girls are so fucking hot. Pussies are so fucking hot. Sick and dirty is so fucking hot. Shame is so fucking hot.

There she was...being used and loving it. Needing it. Knowing that he was using her and knowing that everyone that ever watched this would be using her and she was still there, being a good girl.

Being used is good. Being used is right.

Maybe the slut hated it and it was just too late now. That turned Cynthia on even more. Shame is so fucking hot..

But the guy? The guy was totally ruining things. He was using her right, just...pumping that hole, but he was so...muscled up and gross. Everything that wasn’t supposed to be hard kinda was and it was gross. Fucking him just looked uncomfortable. It was way better when she focused on the hot, dirty slut getting used that looked like she loved it, and maybe she didn’t. It was so much better to focus on the tame, obedient slut. Her hand slipped under her belly and found her clit, groaning while she worked herself, becoming more excited, yet relaxing into it, feeling like she found the sweet spot when it came to using her brain.

So focused was she that she screamed, startled, when she felt weight on top of her and heard an excited, “What’cha watchin’, sissy?”

Cynthia scrambled to try to compose herself, descending into what reminded her of something that might have happened in their teenage years “Nothing. Jesus, what the fuck are you doing in here? This is my room.”

“Noooo,” Krissi said, keeping her from closing the lid, lifting it to get a better look, “Ooooo, nice. Who’s the slut?”

“What difference does it make?”

“None, really,” Kris answered with certainty. “Getting pumped is what she’s for, just curious about what turns my sister on is all.”

“Eww.” With that, she realized that Kris was still naked, too, her bare breasts pressing into her back. “Jesus, Kris, put some fucking clothes on.”

“What for? I was already naked. Now you’re naked. I just figured it was naked time. Besides, we’re in the house and it’s just us, so what do we need clothes for?”

Cynthia squirmed to try to get out from under. “Because we’re fucking adults and it’s...” At just that moment, their tits rubbed one another as they pressed together, “...sick.” What was intended to be a try at pushing Kris off of her short-circuited with the thought and the sensation, leaving her hands to rest on Kris’s shoulders and her close enough to Kris to feel her warm breath and see her pouting lips in bright red, noticing the fresh heavy makeup. She looked so trashy. She looked like one of the porn queens in the videos. She’d never looked so beautiful.

“And dirty? Is it sick and dirty to be laying naked under your naked sister? It really kinda is,” she snickered, “And not even ‘kinda.’ It’s really sick and dirty to be under your sister like this.” Kris heard her let go of the breath her sister had been holding. “But it doesn’t seem to bother you as much as it should, does it; being sick and dirty under your sister.”

She found some backbone in her voice. “Get. Off.”

“Sick and dirty, naked under your sister.”

“Get. Off.” The hands on her shoulders were still there and all the push turned into was a squeeze.

“You’re looking at me like you’re sick and dirty. You like my pretty makeup. I feel soooo much righter in it and you look like you like how sexy I look.”

Girls are so fucking hot.

She was so lost in that single thought as she looked at the porn whore in front of her that she barely noticed the whore reach back to the nightstand and pluck her phone from it. Cynthia watched those eyes look away from her and to the phone. She heard the room fill with a sweet hissing pink and she relaxed as it cradled her brain and let her float on it wherever it might take her. She tried one more time. “Get off.”

Krissi obeyed, lifting herself from Cynthia’s body as her thumb danced with conviction as she texted. “You wanna get off, honey? I’ll get you off. I’d love to get my sister off, even if it’s sick and dirty.”

“It is,” she whispered. “You shouldn’t do that,” came with a dirty, nervous smile, as she hoped Kris might find the self-control that she was losing for her.

“Why not? Sick and dirty makes everything so hot. You have no idea the shit me and my girlfriend do on videos, and that’s not even counting the private ones, and sick and dirty makes it sooo much better.” She dropped her phone on the bed. So, why don’t you let me get you off? It’ll feel better and you’ll cum way harder because someone else is doing it for you.”

Her head rolled left and right slowly, saying no the way she remembered that she should to something so nasty even though nasty was hot. Even the pink in her brain was warmer now. “That’s...sick.”

“C’mon, Cyndi. You want me to. I can see it, you horny little cunt. There’s no reason for me not to do it other than you’re all fuckin’ hung up on right and wrong over it. I’m not hung up about it. I’m here and it’s just us. Who’s gonna know? Be a slut for one fuckin’ day. Do something that will make you feel ashamed and horny for the rest of your fucking life.”

Her hand went to one of those full, insanely proud tits and ran her middle finger slowly up and down her right nipple. “I could be doing this to your clit right this minute, you know, but you’re all shamey about it. Shame is hot. Don’t you think shame is hot? I think shame is hot. Do you want to let me do something to you that makes you feel ashamed and hot? That way I did it. You can tell yourself I made you if you want. You can tell yourself I played with your brain and made you like it if you want. You can tell yourself I made you.”

Her brain trudged through the logic and the needs of her body Not my fault if I’m sick and dirty because she made me. My sister made me. “You won’t tell anybody you made me do it?”

Krissi smiled so sweetly it made more pink. “Nope. In fact, if you roll over on all fours, you can even not see me and tell yourself it’s not your sister Krissi finger-pumping your pussy if you want.”

Pink-addled Cynthia was sold. It was all so dirty and sick, and shameful, and her cunt was already drooling for it. She placed herself on all fours, her knees wide and her tits hanging like teats on a barn animal, waiting for the sick and dirty things that her sister Krissi would make her let Krissi do to her.

“Here, let’s get you something good to watch, sissy.” She positioned the laptop in front of Cyndi and angled the screen up perfectly as she called up her own small, but growing content page and picked “Greased Up Girlies,” one of her personal faves, and upped the volume. She loved her fuck videos with the volume up and the Cube-y playing. Cyndi did, too. “Oh my fucking God.”

Krissi spoke with pride after sucking her fingers to get them ready while she recovered her phone and opened the Cube-y app, getting it ready so that when she spoke, it’d come through the speaker with her. “I love it. That’s me and my girlfriend. And lots of bottles of sex oil.”

Cynthia stared, pupils dilated as she watched her own sister rolling around in a plastic kiddie pool in some garage somewhere, slipping, sliding, moaning, and giggling like idiots with fingers roaming everywhere. It all looked even hotter under the harsh overhead light, it leaving them to glisten under it, glittering almost like jewels.

Cynthia’s eyes reflected the light.

Like hot, nasty, lesbian jewels.

Her jaw dropped when three fingers began sawing in and out of her, the near constant spasms of her cunt grabbing at them and Krissi loved that feeling because greedy cunnies were the best ones. Candi’s was greedy like that all the time. Cyndi’s was so greedy that she began to hump those fingers back and Krissi just let her for a while. Krissi just let her watch and feel good and cum when she felt like it, which was lots and lots after the first one forced its way out.

When she looked at Cynthia again, those tits were flopping back and forth while her expression was still slack-jawed and empty with almost nothing behind the eyes anymore. All there was for Cynthia was an endless sea of pink to float in. When she heard Kris speak to her it was like a special stereo feed; one for her ears and another settling into her brain. “Look at you watch your sister fuck on her videos, Cynthia would never do that, would she?”

She could barely remember that girl, but she didn’t like things that felt good like the pink felt good; like watching her sister power fuck another girl with a glossy black toy, both all oiled up in a plastic pool.

“Would she?”

“Nuh-uh.”

“Because Cynthia’s no fucking fun. She doesn’t like fucking like Cyndi does. Stupid Cynthia wasting all her time trying to think. Thinking is too fucking hard anyway, right?”

That was true. She learned that much this morning what with all those numbers and stupid words that she couldn’t even figure out. “Yeah. Thinking is way too fucking hard.”

She kissed her sister’s heart-shaped ass. “Tell me about it. But Cyndi likes it. Cyndi likes watching her sister fuck her girlfriend. Cyndi likes her sister fucking her.”

“’Cause it’s sick and dirty and you made me.” Her voice turned plaintive as it took on a tone that sounded like the emptiness in her eyes. “Will you make me fuck her, too?”

“I won’t have to. You already want to.”

That was true, too. She pushed hard on those fingers, imagining all the things that Cyndi would do now that she realized how much more fun Cyndi already was than Cynthia. “Yeah.”

“Want me to make you do something though?” Cyndi squealed when Krissi bit that ass that was plush enough to need biting. ‘Is that what you want?”

She groaned at the thought. “Yes. Bad.”

“That’s cool because your big sissy has just the thing.” She went to the laptop and cued up another video. This one from the man’s point of view, the man on the bed, his big belly obscuring Krissi’s pussy as she rode him like a good and proper slut. He’d alternate between clawing and slapping at her tits and simply hanging back and doing nothing while she rode. He’d slap those tits hard enough to make her yelp while she just took it and rode. “That’s nice, you stupid bitch. You don’t know how to do much, but what you know how to do, holy fuck, titty cow, you know what to do.”

Cyndi sighed wantonly just looking at him, all soft where he needed to be with a big, yummy tummy and nice thighs, but nice and hard where a guy should be and not all wound around working out and hard and gross all over. She bit her lip, “You suck. You always get all the hottest guys.”

“I know,” the answer was loving and prideful. “I got the best one in the whole world now.” Hearing it resonate in her pink, wet brain, Cyndi believed it as Krissi helped her settle her back against the headboard, legs nice and wide as she spoke. That’s why I have a girlfriend and we share him. There are so many things to do to keep Teddy happy on top of all the fucking he likes.”

With a man’s man like that, Cyndi wasn’t surprised. She gasped as Krissi expertly suckled one nipple, then the next before kissing down her belly. She’s gonna eat me. Oh, God, my sister’s gonna incest my pussy with her nasty fucking tongue. That’s so sick and dirty.

Good thing sick and dirty makes me hot.

Words. She needed words again even if she couldn’t take her eyes off her hot, nasty sister with it “What...ummm...what do you want me to do?”

In response, Krissi flicked her tongue on that clit to punctuate her words, making Cyndi jump each time. “All I want you to do is watch.”

Flick.

“And fall in love.”

Flick.

“Fall in love with my Teddy like I love Teddy.”

Obscene suckle. Flick.

“Love how he looks.”

Flick.

“Talks.”

Flick.

“Treats me.”

A suckle of that clit followed by a lazy vertical drag of the lips that made Cyndi cry out.

“Fucks me.”

Suckle.

“Needs me.”

Flick.

“Watch until you love Teddy more than you love anything.” She spit on her sister’s pussy, preparing for the delicious job of working it all over and seeing how much she could make Krissi scream. “That’s all I want you to do, sissy. Watch until you love him more than anything. Watch until you love Teddy more than you will ever, ever love you. When we’re just alike, we can be together for always.”

Krissi locked her lips to the slit before her.

While her sister licked, Cyndi, relaxing her on a beautiful, perfect pink cloud, she started to do what her sister wanted her to do.

It didn’t take long at all.

She told Krissi so but Krissi just kept on licking, pausing only to order her. “Keep doing what I told you.”

She swam under the pink. She drowned in the pink, but she kept doing what she was told.

Cyndi had never been happier.

* * *

He knew, but asked anyway. “Which slut is this?”

They both swooned at the sweet, sweet voice of Teddy on the speakerphone as they lay on their bellies with the phone at the foot of their bed. “Hi, lovey,” Krissi said sweetly “I miss you tons.”

“I miss you, too, baby. Did you do what I asked you to?”

Her voice was a joyful squee. “I didn’t fuck it up, even one little bit.” She nudged her sister playfully. “Did I?”

‘You fucked it up a lot.” The giggles were just short of maniacal, “With fingers. With your tongue. With all your nasty toys.”

Teddy was happy and when Teddy was happy, the universe was perfection. “Hi, Cynthia. I’ve heard a lot about you.” He sounded almost bashful.

Her voice was love. “I heard a lot about you, too. But, if it’s okay, my name is Cyndi.”

“Awww...that’s so much nicer than Cynthia, huh? So, Cyndi, how much did your sister tell you about me?”

The lovey pink was always in her brain now. “Enough to know that I love you more than I’ll ever love anything.”

“Mmmm...great, honey. Good job, Krissi cow.”

She closed her eyes and basked in the praise like it was a tangible thing.

“I can’t wait to meet you, Cyndi. I can’t wait to climb on you and get milked real good.”

“I’ll milk that dick better than my sister does, I promise.”

“There was another nudge. “You will not. You haven’t even fucked him yet. There’s no way you know how to fuck him better than me.”

“Girls, girls, girls. How about you quit fussing and fighting and throw together a nice video so I’ll know what’s coming my way? Come back as soon as you can and don’t forget to send me that movie.”

He ended the call and they thrilled at the idea of being able to please him even before they could be there to please him.

“He’s so the best,” Krissi said.

“I know. You were so right about everything.”

“I’m still seriously smart,” she said, and there was a bit of attitude with it. She suddenly remembered what Teddy said and swiped her phone, sitting on the edge of the bed now to set things up. “Let’s make a fuck movie.”

Cyndi started kissing up her spine to her neck. Girls were so hot, and the sick and nasty that the girl just now was her sister made her irresistible. “Been thinking. Mom was all worried about you...”

“For nothing.

“Well, yeah. But she was all worried about you already and when I go home with you we’ll both be gone and her and Dad will worry more.”

Krissi was barely paying attention, finally getting the phone angled on the nightstand to get a view of most of the bed. “So? I don’t care. We’re fine.”

‘Yeah.” There was concern, even as she was consumed with kissing up her shoulder to her neck. “But what if they came to get us? Or called the cops. It’d be sad and it’d make trouble for Teddy.”

Cyndi was right. She heard Teddy’s voice in her head. Dumb bitch, and it wasn’t in the fun way. When he said it mean, he was always right and she always deserved it. “What do we do?”

“We tell them we’re going away together.”

She huffed. “We are. How does that not make trouble for Teddy?”

“No, silly.” Cyndi kissed her cheek and let both hands slide down to cup her sister’s tits roughly the way she knew Teddy would and got the same sound out of it that she gave him, which made her fall in love with both of them just a little bit more. “We tell them we’re going away together. If they knew that their girls were going away together to be away from everybody so they could dirty, incest lesbodyke in peace, they’d never wanna see us again anyway.”

You wanna tell ’em?”

“We don’t have to tell ’em shit.” She paused, playing with the thought before releasing it. “We’re making a video anyway. Who says Teddy’s the only one that gets it?”

Krissi beamed. Cyndi was crazy fucking smart. In her excitement she turned and wrapped herself in her sister’s body and her sister returned the embrace, kissing her with that excitement and more than a little passion. “You realize how hard Teddy will get knowing we sent it to them?”

“So hard and cummy that maybe he doesn’t have anything left for us for a while after we get back,” Cyndi guessed. “But I can live with it.”

Another kiss came as Krissi’s pussy prepared to service Teddy and her own filth. “Me, too. You are sooo sick and dirty, honey.”

“I can live with that, too.” She eyed how their tits mashed together. “I’m not anything else now and I love it.”

Krissi hurriedly started recording so that, when it began, they were cheek to cheek with Cyndi on top of her. “Hi, Mom and Dad,” she said, her voice thrilled and bubbly.

“Hi.” Cyndi said, giving a little wave.

Krissi took the lead. “The bad news for you guys is that I doubt there are gonna be any grandkids for you. The good news is that we’ve realized that men totally fucking suck and we spent way too much time trying to make it work with them.”

“When who we really, truly love is each other,” Cyndi added, thrilling in that everything she was doing and saying was to make them being together and being with Teddy together happen. “It sorta feels good to finally admit that this is the bitch I love and I’m gonna love her every day. I’m gonna suck this pussy every night. And we don’t give a fuck what you or anybody thinks about anything anymore.”

Krissi was giddy. “Nope.”

Cyndi looked wicked. “Watch this shit, Dad. Maybe you’ll pick up some tips.”

When that mouth touched her most intimate parts, Krissi’s back arched and she whined in ecstasy, not acting for the camera in the slightest before she smiled pretty for Mom and Dad.

End.
