Little Sister Dominique

Chapter Three

Stephanie didn't sleep that night.

After her sister nearly caught her in the act of panty sniffing and masturbating Stephanie had barely been able to look at Dominique in the eye. Instead, she'd quickly excused herself to the bathroom, showered for much longer than was normal, and hurried back to her room.

The dark blue duvet was still wet when she sat down in her towel. The smell of her juices lingered in the air. The evidence of what she'd done made racked Stephanie with guilt and fear. And all of that is without mentioning the most incriminating item still hidden under her pillow. Dominique's dirty panties were within mere centimetres away.

She tossed and turned all night, but sleep would take her. She felt ill. She got up several times to go to the bathroom or have a drink, hoping beyond hope that it might help ease her, but nothing worked. All she could smell was the scent of pussy. It got so bad that she actually opened a window, despite how cold it made the room, in order to air it out a bit. When dawn finally broke, she simply gave up and tried to get in an early start.

This was a good idea for a handful of reasons. Firstly, it meant she could get a head start at work for the day, something that would put her in the bosses' good books and also help actually leave on time for once. Secondly, it gave her something to do instead of sitting about worrying all day. A busy mind would be less prone to lambast her with waves of guilt, and being mobile would surely tire her out for the following night. Lastly, and perhaps most importantly, it would get her away from Dominique.

Stephanie felt kind of guilty about that last one. After all her little sister was an innocent in all of this. She hadn't left her dirty panties just lying around for her sister to stumble upon. She hadn't made Stephanie do her laundry, or to accidentally leave them out on the floor. She definitely didn't ask for her sister to use those dirty panties as a masturbation aid. That was all Stephanie's fault. It felt kind of cruel to abandon her over something she wasn't even aware of.

But Stephanie was not prepared to face her little sister. Not that morning, not that day, and probably not for the foreseeable future. She knew she was just prolonging the inevitable, and that she'd have to face her sister eventually, but for now she just couldn't bring herself to. Besides, its not like she was about to confess everything to Dominique. She just needed some time to sort her head out first.

She hightailed it out of the apartment to catch the earlier bus without even bothering to make herself a lunch or leave a note for Dominique.

**************************************************************************************************************

That evening Stephanie crept back into the apartment as quietly as she could.

She assumed, correctly, that Dominique would be in her room, as she usually was at this time of day. The hope was that Stephanie could sneak into her room without alerting her sister so she could have a bit of time without having to face her. Even thinking about Dominique was now causing her to blush out of sheer embarrassment.

Silently, she snuck through the lounge and into her bedroom, stopping only to lightly close the door behind her. Mission accomplished, she collapsed on her emerald sheets, lying face up and staring at the ceiling. She'd hoped that throwing herself into work might make her feel better, more like her usual self, but all that she'd really achieved was that she now smelt of sweat after having such a busy day.

Inside her mind what she'd done the previous evening still loomed over her like a dark shadow. She'd tried her best to rationalise it over her lunch break, trying desperately to find a reason why she'd done what she had. Maybe it was simple projection? It wasn't so much her sister she was thinking about, but more herself. It was possible, though unlikely. Maybe Stephanie was actually attracted to girls, and this was just an awkward, kind of safe, way to experiment and fantasise about something she didn't even know she desired. That seemed more likely, but Stephanie couldn't really think of any other women she was attracted to.

She laid there, mulling ideas over and over in her head for about an hour before she heard Dominique knock on her door.

"Steph? Are you home already?"

Stephanie, bolted up right. She had planned on easing into a conversation with Dominique. Talk about dinner, or rant to her about work. She didn't expect Dominique to be at the actual scene of the crime when she did so. As long as she kept her bedroom door closed it was almost like it didn't happen.

"Yeah." Stephanie replied, curtly. "I'll be out in a minute."

"Oh, okay." Dominique said.

"Yeah, I just have to take a shower and then we can make some dinner." Stephanie tried very hard to sound casual.

"Right, sure." Dominique murmured. "Let me know when you're done?"

"Sure thing sis!" Stephanie said, only realising afterward that she'd never called her sister "sis" before in her entire life.

Her heart still pounding, Stephanie quickly got up and bolted into the bathroom. At least here she could have a few moments to prepare herself.

She stood under the warm water, letting the gushing liquid purge her of her sweat and her fears. It wasn't supposed to be a hair wash night, but Stephanie extended her time just a little bit more by both shampooing and conditioning her long brown hair. She was being ridiculous, and she knew it. She should just get over herself and stop being weird.

When she exited the shower, dressed only in a towel she had wrapped just under her arms around her, she yelled out to Dominique that she'd be ready to make a start on dinner as soon as she'd changed. However, what met her eyes when she got back to her room shook her resolve.

Dominique sat on the edge of Stephanie's bed. She looked grumpy. Not quite angry, not quite hurt, but she was definitely not the happy, carefree, girl she usually was. Stephanie shuffled into the room and just stood in front of her sister awkwardly for a moment.

"We need to talk." Dominique said bluntly.

"Err... ye-yeah..." Stephanie breathed, her heart in her throat. Was she about to be found out?

"I'm kind of upset that you haven't even asked me about how the promo thing went." Dominique told her. "I mean, I get that maybe you were tired last night or whatever, but you disappeared at like six this morning or something, and then didn't even bother to let me know you'd got home. I know this is your place, and I'm just a guest, but I thought you'd at least try to make a bit of effort and support me just a little."

Stephanie felt as though the weight of the world had just been dropped off her shoulders. Was this all it was? She hadn't been found out. This was good. This was really good!

But then she realised what her sister was actually saying. She felt unseen, unsupported. In the madness that had been the last twenty-four hours Stephanie had done her best to avoid her sister at all costs. Dominique was actually right to call her out on it. She had gone to do a promo yesterday. Stephanie hadn't even thought about it once until she'd been reminded just now. She was being a bad sister.

"You're right." Stephanie said. "I'm sorry. I just got a little preoccupied with some, err, some other stuff. I didn't mean to make you feel like I don't care. Because I do."

"No, that's fine." Dominique replied, looking up at her sister with her big blue eyes. "But you can see why I'd be upset right?"

"Of course I can." Stephanie nodded, her wet brown hair flopping slightly over her face. "I'm genuinely really sorry for not taking more an interest. How did it go yesterday?"

"I didn't get it." Dominique shrugged.

"Oh no! Why not?" Stephanie asked.

"Apparently I was too petite for what they were looking for." Dominique said. "I don't even know what that means as the girl who got it was the same size as me, but it's no biggie."

Stephanie nodded, not really understanding, but very grateful that her sister seemed to have forgiven her for her failings. Quite how she'd react if she knew the full extent of those failings would be another thing entirely but for now Stephanie was content to just have things back to normal. Everything that had happened simply didn't matter. Being there for her sister was more important than a slightly weird sex drive.

"I'm sorry you didn't get it." Stephanie said, sitting down next to Dominique and putting her arm around her.

"Thanks Steph." Dominique purred, resting her head momentarily on her older sibling. "But these things happen. I'm sure I'll find something else."

"Yeah, definitely." Stephanie agreed.

They sat there for a moment or two in silence. It wasn't an awkward silence, just the kind that occurs when two people simply take a moment to be together. To exist in the same room, the same space. To just enjoy each other's company and the feeling of solidarity it brought.

Stephanie had been worried earlier that whatever her libido was doing would affect their relationship, but sitting there with her sister, in that wonderful moment, made her realise just how much she loved her. Because she did love her. All those worries and panics from before all seemed to fade away in the warmth of their embrace.

"You haven't noticed yet have you?" Dominique said, breaking the silence and stealing away the moment between them.

"Noticed what?" Stephanie asked.

"Well, I know I left my room an absolute mess before I went out yesterday." Dominique began, "And yet when I got home, I saw you had tidied up. You didn't have to do that by the way but thank you! Anyway, I was bored earlier this afternoon and I figured I'd return the favour and tidy up a bit. So, I came in here and hoovered the carpet and changed your bedding and stuff."

"You did?" Stephanie was shocked. She'd never heard of Dominique acting so domesticated before. It was actually kind of endearing.

"Yeah, I don't know what you'd spilt on the floor over there, but it was all over your duvet too." Dominique said.

"Wait a minute," Stephanie suddenly felt very hot and stiff as the realisation settled in. "You changed my bedsheets?"

"Yeah. You couldn't tell?" Dominique laughed pulling her head away.

Stephanie glanced down at her bed. The sheets were emerald green and looked spotless. Which was all well and good except last night she'd tried, and failed, to sleep in dark blue ones. These were different sheets. Even the pillowcases had been swapped over for matching ones. And if, as Stephanie suddenly realised, Dominique had moved her pillows to change the sheets, then Dominique would have seen the dirty panties underneath. She would of course immediately recognise them as her own used underwear and probably question how they had ended up there and just Stephanie had been doing with them.

"What's the matter?" Dominique asked teasingly. "You look like you've seen a ghost."

"I... err... I..." Stephanie stammered, trying to find something to say.

"Are you worried about where the panties have gone?" Dominique's tone shifted down from playful to accusatory.

"Wh-what?" Stephanie gasped.

"The panties." Dominique's faced was now deadly serious. "Or more accurately, my panties. Don't you want to know where they are?"

"I don't know what you mean." Stephanie said, leaning away from her sister and attempting to get up.

"Yes, you do!" Dominique beat Stephanie to the punch and pushed her back onto the bed. "You had a pair of my dirty panties in here under your pillow. Don't try to deny it!"

"They fell out of the washing machine." Stephanie sputtered, feeling quite weak as her stood over her. "I brought them in here to add to the wash bin."

"If that's the case, how did they end up under your pillow?" Dominique demanded.

Stephanie's brain was firing a thousand and one different answers around her mind, each more ludicrous than the next. She couldn't tell her sister the truth. Dominique seemed mad enough about the panty theft alone. Knowing the full extent of what her elder sibling had done might just set her over the edge. Instead of saying anything incriminating Stephanie just tried to crawl backwards up on to the bed and stayed silent.

"No answers huh?" Dominique bent forward slightly and place her hand down on the bed next to Stephanie. "That's okay. I already know what happened."

"You do?" Stephanie gasped.

"Didn't take a genius to figure it out." Dominique snapped.

"Figure what out?" Stephanie said, still trying to feign innocence.

"The marks on your duvet and on the floor. The fact you've avoided me all day. How flustered you looked when you went to get a shower last night. The smell of your pussy juices lingering in the air. My panties under your pillow. Need I go on? You were wanking before I got home last night, weren't you? You were wanking and sniffing my dirty panties as you did it." Dominique raised her voice.

"Ssshhh!" Pleaded Stephanie. "The neighbours will hear!"

"Screw the neighbours!" Dominique raged. "They might be interested to know that you're a pervert panty stealer!"

"No, I'm not!" Stephanie cried out, tears forming in her eyes. "No, I'm not! It's not like that!"

Dominique frowned and stood back to her full height. She took a few deep breaths to centre herself and when she spoke, she did so with a calmer yet weightier voice.

"What happened?" She asked. "Tell me honestly."

"I... I really was going to put them in the wash bin." Stephanie said. "But I don't know... something happened. I was tired and horny and when I felt how wet they were it just got me going."

"Got you going?" Dominique raised an eyebrow. "How?"

"What do you mean?" Stephanie asked as she looked up at her suddenly terrifying little sister.

"Tell me what you did." She commanded. "No, tell you what, show me what you did."

"But I, what?" Stephanie was shocked.

"Let me make this easier for you." Dominique said as she reached into her back pocket and pulled out the pair of white panties. "Take these and show me what you did last night."

"Dominique! No! I, I couldn't..." Stephanie gasped, unable to comprehend what was being asked of her, but equally unable to take her eyes off of the panties in her sister's hand.

"I'll say it one last time." Dominique said, leaning forward and grabbing the bottom the towel Stephanie was wearing. "Take these panties and show me what you did, or I will tell mother what you have done and how perverted you are."

"You wouldn't..." Stephanie tried to plead.

"I would." Dominique interrupted. "So, if you don't want to be the family pariah I suggest you get on with the show."

Stephanie didn't know what to do. She didn't ever except to be put in this kind of a situation. Up until now everything had been a kind of fantasy. It existed only in her head, and whilst it troubled her, she had never anticipated being asked to relive it for someone else. Much less her little sister. A sister who was less asking and more instructing her to do it.

As much as she didn't want to, Stephanie reached for the panties and took them from Dominique. If her sister's threats were sincere, and she really was planning on telling their mother, it could ruin Stephanie's life. They might not always see eye to eye, but Stephanie loved her mother and depended on her. If her was outed as some sort of pervert that relationship would be gone. Not to mention if word got around to anyone else. What would the people she worked with think about it all? Her friends even? Stephanie couldn't take that risk.

"Good girl, Steph." Dominique said as Stephanie held the panties in her hands. "Now show me what you did."

Stephanie obeyed silently. She lifted the panties to her nose and sniffed them. The same tingling sensation started to run through her body, but the awkwardness of the situation was preventing her from getting too turned on.

"I know you did more than just sniff them." Dominique crossed her arms. "And you definitely weren't wearing a towel either. Lose it."

"What?" Stephanie looked up at her domineering sibling.

"The towel." Dominique repeated, uncrossing one arm and gesturing at the only piece of fabric concealing Stephanie's modesty. "Take it off."

"Seriously?" Stephanie breathed, her nose still picking up the scent of pussy juice from the panties.

"Yes." Dominique nodded.

Stephanie felt like she was in some kind of mad bizarro world. It was like the set of some weird porn film where somehow the solution to every problem is to have sex. Except that this wasn't a porn shoot, and she wasn't being asked to have sex. She was being commanded by her sister to masturbate, naked, in front of her and sniff her dirty panties. How this was supposed to be make some kind of penance Stephanie didn't understand.

But she didn't need to understand. She only had to do what Dominique asked. Even if it was awkward and embarrassing, it was worth it if it meant that her life wouldn't be ruined.

Hesitantly, Stephanie dropped the towel off her and revealed her naked flesh underneath. Initially she tried to cover her more intimate areas with her hands, but Dominique had leaned forward and pushed her onto her back, ordering her to put on a better show. It was only when she raised her legs in the air and spread them, when she was at her most exposed, she suddenly felt the lustful urges rise up inside her.

She sniffed deeply on the panties again and let her free hand roam over body. Last night she had gone straight for her pussy but today she was putting on a bit more of a show. She did have an audience after all. She gently tugged on her right nipple before her hand wound its way down to her crotch.

"You look like you're starting to enjoy that." Dominique said, eyes her naked sister with interest. "Are you?"

Stephanie looked at her sister dead in the eyes and nodded. Then without breaking eye contact with her sibling she sniffed, audibly, on the panties in her hand, and ran her fingers over her moistening labia.

"How disgusting." Dominique remarked, nearly stopping Stephanie in her tracks. "Do you have any idea how dirty you're being right now?"

The cruel words should have stopped Stephanie in her tracks. A normal person wouldn't let another person speak to them that way, even if it was their sister. A normal person would realise they the words were right and stop, what she was doing really was dirty and wrong. But Stephanie was not a normal person, not anymore. She was a slave to her lust, and right now, she didn't give a damn about being dirty as long as her leaking pussy got off.

A torrent of juices oozed out of her as she continues rubbing her clitoris and labia. He eyes were still fixed on her sister, fully committing to the act she was putting on. Going so far with it even to slightly twist herself and give Dominique a better view.

"You should be ashamed of yourself." Dominique stated as she watched with a growing hunger in eyes. "Tell me you're ashamed."

"I'm ashamed." Stephanie said instantly, though it was slightly muffled the panties in her face.

"You're a dirty, disgusting, panty stealing pervert, aren't you? What are you?" Dominique encouraged her sibling.

"I'm a dirty, disgusting panty stealing pervert." Stephanie said, rubbing furiously as her juices poured out of her.

"Good girl." Dominique said. "You may stop now."

"What?" Stephanie said, not slowing down.

"I said stop." Dominique ordered with an intensity that seemed to come from nowhere.

The shook of her sister's dominance caused Stephanie to obey. Her hand stop rubbing and moved itself slightly out of the way so that Dominique could the twitching, sloppy, mess that Stephanie had made of herself. She laid there, fully exposed and bare before her little sister, never once taking her eyes off her, merely waiting for the next instruction.

"Give me the panties." Dominique demanded.

Almost reluctantly Stephanie removed the panties from her face and handed them to Dominique. She had no clue where this was going, no idea what the hell she was even doing, and not a single thing could make her stop. Well, apart from her sister's stern voice.

Dominique took the panties and rubbed her fingers over them. With her free hand she reached down to the buttons on her jeans and undid them. Stephanie watched with rapture as the jeans were loosened and ever so slightly tugged down. She'd hoped to catch a glimpse of something, but all she saw was a momentary flash of flesh.

"These panties aren't dirty enough." Dominique explained as she turned around and away from Stephanie's view.

Stephanie watched her little sister trying to figure out what she was doing. It looked to her as though Dominique had taken the dirty panties and was rubbing them under her jeans, and presumably under her underwear, against her crotch. When she finally turned back around after what like an eternity but was really just a few moments, she threw the panties back at Stephanie's naked body.

"There." Dominique said, her jeans still undone and now showing a thin sliver of the lacy green panties she was currently wearing underneath. "Rub those on yourself, pervert."

Stephanie reached for the panties that had fallen on her stomach and felt them. They were practically dripping wet. To the point where Stephanie could have wrung them out to extract a small waterfall of her sister's juices. Clearly whatever was happening here was turning Dominique on as much as Stephanie.

She began to rub the panties over her naked body. Lathering her little sister's pussy juice over her breasts and stomach, breathing deeply as the smell reached her nostrils, and trying her best to resist the urge to cum right there and then.

"Look at you." Dominique practically purred. "You look so... so hot. I love it."

Her sister's words spurred her on even more and Stephanie, without prompting, took the panties off her stomach and rubbed them over her face. She relished the feel of the slimy fabric on her cheeks and brought them panties to her lips. Without even thinking about what she doing she stuffed the wettest part she could find into her mouth and sucked on them, letting out a deep guttural moan as she did so.

"That's really disgusting." Dominique said, though this time with a smile. "Do you like how they taste pervert?"

"Mmm hmmm." Stephanie nodded through the panties in her mouth.

"What am I going to do with you?" her little sister mused. "I tell you what, if you can cum in the next two minutes, I won't tell mother about any of this. Think you can do that?"

Stephanie didn't need any more encouragement; her hand leapt to her pussy and began rubbing. She panted for breath and sucked hard on the moist fabric in her mouth.

"I didn't say go yet." Dominique's word cut her off. "I will count you down from three, when I get to one you will have two minutes to cum. Here, I'll even get my phone out to time you."

Dominique pulled out her phone and set a timer, showing the screen to Stephanie when it was all set up. She stood over her naked sister, as though soaking up the view, and smiled devilishly.

"Okay pervert. Ready? Three, two, one... go!" She said clicking the phone.

Stephanie masturbated like her life depended on it. she rubbed her pussy hard and fast, not caring as her juices splashed and sloshed all over the place. Not caring that her sister watching her intently. Not caring that what she was doing was disgusting and dirty. In fact, if anything it was precisely because of those reasons that she was so turned on.

She liked being dirty. She enjoyed how taboo and perverted this whole thing made her feel. It was liberating and empowering, even though she was actually just relinquishing control over to her base desires. She didn't care if she was a dirty panty stealing pervert, she didn't care that what she was doing was embarrassing and shameful, she only cared about how deliciously horny it made her.

It didn't take Stephanie two minutes to achieve orgasm. It didn't even take her one. She was so revved up from everything going on she climaxed barely thirty seconds into the timer.

She clenched down hard on the panties in her mouth, using them to muffle her shrieks of delight as he pussy erupted in wave after wave of cum. Dominique even had to take a small step back to avoid getting hit by the torrent steaming out of her sister's vagina. Quite how many times Stephanie actually came she didn't know, it had felt like three back-to-back, but she couldn't be sure.

As Stephanie spasmed and twitched on her bed, she pulled the panties out of her mouth and used them to mop up the fresh juices that had just drenched her naked body. Once some had been absorbed, she instinctively brought the panties back to her mouth and sucked on the fabric, relishing the taste of her pussy juices now mixed with those of her sister.

"Wow..." Dominique gasped. "That was definitely something."

Stephanie wanted to say something, but quite what she didn't know. Was there anything you could even say in situations like these? Besides, even if she'd had the right words, her body was exhausted and her brain was swimming in endorphins, rendering her utterly unable to formulate words. That and she didn't want to take the panties out of her mouth yet.

"I, err..." Dominique stuttered, looking a bit shocked now that the moment had passed. "Steph, that was... that was..."

She seemed to be struggling to find the words too. If she had planned this whole thing out, which it kinda of seemed like she had, she clearly hadn't prepared for this moment. There were traces of lust in her eyes, but also of shock, fear, and a completely incapacity to believe what she'd just witnessed. Stephanie hoped beyond hope that what had just happened between them wouldn't destroy their relationship. If Dominique had second thoughts about it now, everything they had could be ruined.

"Steph that was so fucking hot." Dominique purred. "Now it's my turn!"

Stephanie couldn't help but smile. Maybe her relationship with her sister wasn't over quite yet. Maybe it was just the beginning of a new chapter.

Only time would tell.
