“Gail – you’re home!” Cath squealed, thundering down the stairs and almost leaping into her step-sister’s arms.

Gail, to her credit, caught her, smiling despite herself, and crushed her in a warm hug. Between the hard bones of Gail’s corset and her own whipcord muscles, it was a very firm hug, but definitely a warm one.

“Hey kid,” Gail set Cath gently back on the floor. “I was only gone a few weeks – yeesh.”

“I know, I know, but there’s so much I wanted to tell you and… I’m sorry,” Cath suddenly noticed the girl stood behind Gail. “I’m so sorry, I did not see you there.”

“Not a problem,” a slim blonde girl with unfairly long legs and a perfect hourglass figure said brightly. “Gail, where’s the loo?”

“Just down there Marie,” Gail pointed.

The girl slid past Gail and hurried to the aforementioned room. Cath looked up at her step-sister, biting her lip.

“Oh no, I know that look,” Gail said, shutting the front door with a wry smile. “You look just like your Mum when you pull that face.”

“It’s just… Lewis is off at his swimming try-outs and Mum and Joe have both gone with him and won’t be back for the end of the week…” Cath said awkwardly. “I thought we’d have more time to… ah… hang out.”

“You mean more time for me to tie you up and leave you to squirm?” Gail rolled her eyes. “Were you going to give me a chance to get over the threshold before throwing the ropes at me?”

“Yes, but…” Cath trailed off at the sound of the toilet flushing.

Gail smiled and looked up as Marie reappeared from the toilet.

“Marie, meet my step-sister Catherine,” Gail introduced them. “Cath, this is Marisole. Marie is my room-mate from university. The bondage addicted little minx wouldn’t let me leave University without her, and threats of violence just seemed to encourage her further.”

“Oh yeah baby,” Marie breathed, fluttering her eyelashes.

“Keep that up and I am going to throttle you,” Gail warned.

“Choke me, go on…”

Gail rolled her green eyes again.

“If you two don’t hit it off, I’ll pack her into the boot of her car and foist her back on her relations,” Gail continued, addressing Cath. “But I thought that you two might enjoy a little variety.”

“Especially as I mostly get stuffed in the cupboard and told to leave her the hell alone,” Marie rolled her eyes.

Cath’s eyes narrowed.

“Basically you’re hoping that the two of us can keep each other entertained so that you can work out and finish your university work,” Cath observed, amused.

“Babe, to get onto the Clinical Psychology Doctorate course you need a first at the very least in the current climate,” Gail said firmly. “I am not taking the risk of falling below those standards. And plus, I thought that it could get a bit awkward and incestuous if I start messing around with you too much, so it’s the perfect use of my slutty annoying roommate.”

“Right here you know,” Marie remarked drily.

“Was I inaccurate at any point?”

Marie mulled that over.

“No, continue,” She grinned.

“How is it incestuous?” Cath demanded.

“Your mother is married to my father, we are technically family,” Gail pointed out.

“Yes, but we’re not blood related. And you’re adopted anyway – Joe’s black and you’re…”

“Not?” Gail finished, amused. “Cath, you’re 18, so at least we don’t have the whole paedophilia stuff going on, but all the same, it’s not something I want on my record.”

Cath pouted. Marie winked a brilliant blue eye at her.

“Come on sugar,” She stepped forwards and put her hands on Cath’s waist. “We can have a lot of fun together.”

“Starting now,” Gail said cheerily. “Cath – run upstairs and put your swimming costume on.”

Cath blinked at her in surprise.

“The black speedo one or my bikini?” She asked uncertainly.

“Your choice,” Gail took off her coat and slung it over the newel post. “Marie, get yourself into that lounge and strip off.”

Marie saluted and sauntered into the lounge, her full hips making her sashay like a cat that knew it always got the cream. They both watched her go, then Cath turned uncertainly to Gail.

“Gail…”

Gail looked at Cath, her green eyes gentle.

“Marie will not judge you,” Gail said quietly. “She is the least judgemental person I’ve ever met, but I can take her back after tea if you want,” Gail said quietly. “I can just tie her up if you don’t want to participate.”

Cath blew out a long breath, and Gail took a step closer, putting a hand on her upper arm.

“Marie knows that if you’re not comfy, I’m taking her home, so she’ll so everything she can do to make this easy on you,” Gail continued. “I thought about texting you to see whether it was okay, but I knew you’d overthink it and freak out. Now, trust me, okay?”

Cath bit her lip.

“Okay,” She said softly.

“Excellent,” Gail gave her a brilliant grin, throwing her green and black plait over her shoulder nonchalantly. “Oh, and while you’re going, could you grab me that coil of the smooth white rope from my bed drawer?”

“Of course,” Cath said with a grin.

By the time Cath had returned, wearing floaty semi-translucent beach dress over her swimming costume, Marie was in the middle of the lounge, trailing her bare feet over the thick red carpet and gazing out through the garden windows. The room was deep crimson and was Cath’s Mother’s favourite room, the walls in red and gold patterned paper with glittering gold draperies over the diaphanous red curtains. Cath’s Indian mother had filled the room with themed nicknacks – everything matched, which made Gail and Marie such a huge shock against it all.

Gail, porcelain pale skin, 6 foot tall and muscled with her black and acid-green hair pulled into a herringbone plait, her ears full of silver piercings, a big crucifix hanging around her neck, studded with green crystals. She had kicked off her stiletto-heeled boots and was stood in her bare feet, her crocodile-effect leather jacket folded over the arm of a chair as she delved through the battered black duffle bag, her ice-pale arms a shock against the black camisole top she was wearing.

“No corset today?” Cath asked.

“Nah, it’s a bitch if you’re planning to do any long-distance driving,” Gail said with the tone of experience. “You can’t sit comfortably, and breathing is generally considered to be a good thing when behind the wheel.”

“And on behalf of all who ride with you, we thank you,” Marie rolled her eyes, pulling her long lion-like mane of blonde hair into a tight ponytail.

She had stripped, and was wearing a streamlined black swimming costume with pink stripes along the sides and a racerback. It clung to her tight waist, skimmed over her flat stomach and emphasised her tidy apple-sized breasts. It showed her long lightly-tanned arms and legs. She was as muscled as Gail, but in a long, lean, more rangy way.

Marie gave Cath a dazzling smile – and at last Cath saw a flaw, she had slightly crooked teeth. Not a in a bad way, but when some-one was that unfairly pretty, it was reassuring to see that they were still human.

“Sorry for how I look,” Marie glanced down at herself. “I was going to head out to the gym, and then Gail said she was splitting and I was determined that she wasn’t about to leave me behind.”
“You’re my room-mate, not my wife, Marie.”

“Come on, we’re practically married.”

“It’s not happening.”

“If you say so sugar,” Marie fluttered her eyelashes at Gail.

Cath looked uncertainly at Gail, and Marie caught the look.

“Don’t panic,” Marie said quickly. “We’re not actually going out or in love or whatever. We’re gym buddies, we just seem to spend a lot more time with each other than I do with any of my partners.”

“To be fair, you do get through them really fucking fast,” Gail observed, comparing 2 skeins of ropes. “How long was the last one? 2 days?”

“But they were 2 amazing days,” Marie said with a slightly euphoric smile, using another hairband to force her hair into a bun.

“You a dirty slaaaaaaag,” Gail teased.

“Come at me bro,” Marie demanded, opening her arms with a grin.

Gail raised an eyebrow and Marie laughed.

“Marie needed some-one to spot weights for her,” Gail explained. “And I needed some-one to teach me how to swim. Marie competed in the world championships when she was younger.”

Cath looked at Marie in surprise.

“Really?”

“Oh yeah,” Marie nodded seriously.

With her long blonde hair tamed back, her face seemed so much sharper, her face sharply angled with slanting cheekbones and a pointed chin. She looked almost elven now, and in the Lord of the Rings kick-ass kind of elf.

“Why did you stop?”

“Injury,” Marie pulled a face. “And once I stopped doing it, it was hard to get back into it. It takes over so much of your life, you can’t eat what you want or drink what you want or stay out late. I just lost the commitment.”

“And have never been able to regain it since,” Gail observed.

“Owch,” Marie put a hand over her heart. “I am mortally wounded.”

“Yeah, yeah, get your tushy over here,” Gail patted a chair.

It was a black leather chair that was set in a permanently reclining position, 2 curved handled made of bent pine on either side. It was Joe’s favourite chair and Cath was very glad that he couldn’t see what was happening to it in his absence.

Gail had the coil of white rope in her hands and a very serious expression. Marie pulled a face and looked at Cathy.

“We’re in trouble, she’s got her domme face on,” She observed with a broad grin.

“Shush,” Gail chastised, flicking her with the end of the rope.

“Yes Madame.”

“Turn.”

Marie turned her back to Gail, who started to weave an intricate chest harness over the black lycra. Cath knew why Gail had asked for it, it did make a glorious contrast. Cath couldn’t help staring at Marie’s long lean body as it was restrained and constrained and felt the ropes bite around her, making her shift slightly uncomfortably. She looked up at Marie’s face to check that she hadn’t seen, but realised that Marie wasn’t paying attention to her or anything else. Her slightly crooked teeth were biting into her full bottom lip, her eyes slightly lidded, her breathing erratic as Gail gently tightened the whole bodysuit of ropes, making her gasp softly.

“You okay?” Gail asked softly.

“Mhmm,” Marie nodded assent.

“Okay, take a seat.”

Marie took a step, biting down harder on her lip as the ropes chafed against her barely-covered skin, and slowly lowered herself into the chair, cuddling back into the leather.

“This is a bit comfortable for you,” Marie accused her. “You usually have me contorted in all kinds of shapes.”

“Well, I don’t want to scare Cath off,” Gail remarked with a grin.

She wrapped rope over and under Marie’s bust and around the back of the chair, pinning her to the chair and knotting the ropes off behind the chair. Gail then cinched more ropes around her thighs, and shins, then pulled the hair-tie out of her hair and used it to attach her big toes together.

“Excuse me Mistress,” Marie lisped playfully over the words. “Haven’t you forgotten something?”

She waved her arms artistically around in her air.

“Hold your horses,” Gail turned to Cath. “Okay babe, are you in or out?”

Cath bit her lip nervously, twisting her dark hair around her fingers.

“I think I know the problem.”

Gail pinned Marie’s arms to the chair with more cursory loops of rope, not at all like her normal elegantly precise roping, then pulled a leather hourglass out of the duffle-bag.

“Oh, really?” Marie moaned, figetting under the ropes, proving that, cursory or not, they were very much still practical.

“Yes, really.”

Gail wrapped the blindfold around Marie’s eyes and buckled it off tightly.

“Bitch,” Marie said flatly.

“Keep that up and I’ll wash your mouth out again,” Gail warned, then turned to Cath. “Better?”

Cath nodded, for some reason it was much easier, it was just her and Gail again, and she and Gail had done this before. She pulled the loose dress up over her head and revealed her white halterneck bikini. It fitted her to a T, showing her dark caramel skin, with the golden-metal ring between her breasts shining tantalisingly. While her body was definitely not as hard and toned as Marie’s, it was nothing to be ashamed of.

Gail gave her an appraising look, and for some reason that relaxed her. It was such a familiar look, the way Gail was looking at her not in a sexual way, but in a problem solving way, and it set her back on familiar ground.

“Okay,” Gail measured out some rope against her arm. “Let’s keep this light.”

She tied a chest harness around Cath and gently snugged it down.

“Comfy?”

“Yeah, thanks.”

“Okay, turn.”

She turned around and felt bands of rope tightening just above her elbows, forcing her to bend and stick her breasts out slightly. It was such a simple thing, a few bands of rope at the elbows, and suddenly your hands were helplessly stuck behind you.

“How does that feel?”

“Okay.”

“I’ve got an itchy nose,” Marie complained from the chair.

“Suck it up,” was Gail’s helpful advice.

Gail gently steered Cath towards the chair.

“Okay babe,” She said, her hand on Cath’s back warm and comforting. “You get to be the lucky one and top today.”

“How come I don’t get to be ontop?” Marie complained.

“Because you bitch too much.”

Gail helped Cath onto Marie so she was sat on Marie’s lap.

“Oh myyyyyy,” Marie said cheerily.

“Shut up,” Gail poked her in the side. “Legs through the arms please Cath.”

Cath posted her legs through the holes. Gail tied a rope around one ankle, then secured it to the other ankle, and Cath realised, she would not be able to get off the chair until it was released. Gail patted her shoulder gently.

“Now, if I was a cruel person, I’d be tying a lot more ropes, but…” Gail loosed the ropes on Marie’s hands and caught her wrists, looping rope around them so they were tied tightly behind Cath’s back. “I’m feeling merciful tonight.”

“Oh, aren’t we lucky…” Marie said sarcastically.

“Keep that kind of lip going and I’ll stop them entirely,” Gail warned.

“Oh, woe is me.”

Gail took Cath’s hands and secured them to the arms of the chair now, thus meaning that Marie couldn’t get her arms free by lifting them over Cath’s head.

“Can I see now?”

“No.”

“Please.”

“No. You are not perving on my step-sister.”

“Says the woman quite literally tying us together,” Marie remarked, then grinned. “Hey, at least blindfold her then.”

“That seems fair,” Gail looked at Cath. “Would you be okay with that?”

Cath hesitated, then nodded.

“Okay,” Gail pulled another blindfold out of her bag. “Ready?”

Cath nodded again and Gail wrapped the blindfold around her head.

“Right,” there was more rustling from the bag. “I am going to get on with dinner, I trust you girls can entertain yourselves?”

“I see the scheme you’ve got going here! You’re just trying to keep us out of the way while you’re cooking aren’t you?” Marie accused.

“Yup, because I am sick of you nicking all the food before it’s even cooked.”

“Now that is just not mpph! Mppph mhmmm ffff!”

“Suck it up.”

Cath felt something press gently against her lips and opened her mouth to let the mouth-filling panel gag slide in. Gail buckled it off gently, but firmly and patted her on the shoulder.

“I’ll be around,” She promised softly.

Cath nodded and she heard Gail’s jeans rasped softly as she walked away.
