Warning: Non-consensual themes


Things should have changed after being away from home for the better part of a year, that's what Lori thought anyway. Her first year at university had been different certainly, but not in the sort of grand life-changing way she had hoped for. Returning home at the end of the school year Lori found everything pretty much the same. She may as well not have bothered.

As sisters, and only about a year and a half apart, Lori grew up sharing a room with Leni. That hadn't changed either and even now as she lay in her bed staring at the ceiling Lori could hear her soft breathing from across the room. She turned her head to look at Leni but couldn't make out much more than an undefined mound where her blanket covered her. To think one of the biggest problems in Lori's life was sleeping in the same room as her.

It sounded terrible when she thought of it that way. It wasn't like Leni had done anything to deserve being labeled as a problem, even just in her mind. She was as good a sister as Lori could have asked for and she wouldn't have traded her for anything. She just wished she could fix whatever was wrong with her.

Sighing heavily, and knowing she was better off staying put, Lori swung her feet off the side of her bed and stood up. Lori had taken to sleeping naked while she was away, but in acknowledgement of her return home she settled for stripping down to her underwear. Clad in a bra and panties, Lori crossed the room to stand beside her little sister's sleeping form.

Only her head was visible sticking out from under the blanket that covered the rest of her body. Now that Lori was closer, she could make out the features on her face, or at least half of her face. In the months Lori had been at university, Leni had turned seventeen and, if anything, she looked even more adorable than when she left.

Lori didn't know when her bizarre and frustrating obsession had started but it must have been related to them sleeping in the same room. The thing was that as cute as Leni could be during the day, the effect was somehow even stronger when she slept. The sheer look of tranquility and contentment that she held was enough to render me helpless.

"Perfect," I whispered under my breath.

That was the only word she'd come up with that came close to describing how Leni looked to her. Watching her now, Lori saw that same face, the one that had driven her crazy. A little older perhaps but no less perfect than before.

She had hoped that some distance between them would help, that not seeing her for so many months would make her realize that she didn't really feel anything more than a love for her little sister. Unfortunately, the feelings were stronger now, and many of them were definitely unsisterly.

Lori reached down to grasp the top of Leni's blanket and tugged it gently away from her shoulder before stopping herself. She had always managed to keep from actually doing anything more than looking before and that's how it needed to stay. She didn't need to know how messed up she was. Leni didn't deserve to have to deal with Lori's issues. They were for her alone.

For several long moments Lori stood there, blanket still in hand. Slowly, Lori pulled it farther down her body until she reached Leni's waist. She was losing the battle, or maybe winning. Always hard to keep score on internal struggles. She was still just looking Lori told herself, she was just getting the blanket out of the way. It wasn't really anything she hadn't seen before.

Soon Leni's blanket was piled up at the base of the mattress and her entire beautiful form lay before her. She was lying mostly on her stomach with her head turned toward Lori. She had on a t-shirt and pajama pants as usual, the same Lori always used to wear to bed too. She noticed that her shirt had pulled up a little as she slept, exposing maybe an inch or two of skin on her back.

It was weird how interesting skin could be at times. It was constantly visible on other people on their hands or arms or faces, yet sometimes it was different. In the right places or on the right people it turned from an everyday sight to something more fascinating than the greatest work of art. The small patch on her sister's back wasn't quite that amazing, but it was still enough to draw Lori's attention.

Lori's hand went to the gap between Leni's shirt and pants without even bothering to ask permission from her brain. She let her palm lay flat on her back for a moment before jerking it away. Now Lori was going too far, crossing a line she had always managed to avoid in the past. And yet, it felt so good.

Feeling guilty even before she touched her again, Lori returned her hand to Leni's back, pushing the hem of her shirt up a little as Lori spread her fingers out. She slowly ran her hand up Leni's spine to about the mid-point between her waist and neck before sliding it back to its starting position. Having pulled her shirt up some, Lori wondered just how far she could get away with. It couldn't come off, not without actually moving her, and Lori didn't think she'd sleep through that.

Taking hold of the bottom of Leni's shirt on either side of her body, Lori carefully tugged it upward. It was caught between her stomach and the mattress where she lay on it but Lori still managed to get it up to almost the level of her breasts.

Lori paused as she considered the possibilities, then slipped her fingers under the bunched-up edge of Leni's shirt. Only the side of her breast was available to her without rolling Leni over and it really wasn't enough to get much of a feel, but it was more the idea of what she was doing anyway. It was so wrong in so many ways and so very, very exhilarating.

Her heart was pounding and her hesitation was disappearing as Lori's hormones took over. She would still feel bad in the morning and wish she hadn't done any of this, but Lori couldn't stop.

She turned her attention downward to the yet untouched pajama pants that covered her little sister's lower half. They were loose, meant for comfort, and decided she could probably get away with a similar process as Lori done to her shirt. Leni's legs were lying apart slightly, spreading wide enough that Lori wouldn't be able to get her waistband past her knees without pushing them together. That was okay though, she could still get it down far enough for her purposes.

She ended up only pulling Leni's bottoms down to just below her butt where she stopped and just stared. Lori had seen Leni in her underwear or swimsuit plenty of times, and she had a fair idea what she looked like anyway, but still. Like every part of her body, it seemed to fit, not too big or too small but just perfectly curved. 'Why did my sister have to be so goddamn amazing?'

Lori's levels of horniness were getting too high and, despite knowing she should retreat to her bed first, Lori gave in and slipped a hand under her panties. Lori's pussy was so wet already she could fell the moisture had soaked into the front of her panties against her knuckles. For a few minutes she simply played with herself, trying to satisfy her urges enough to regain some control. Her fingers sank easily into her sodden pussy and wished momentarily for her vibrator but couldn't force herself to move from where she was to get it.

Finally, Lori wrenched her hand away and took a couple deep breaths trying to calm down. If all she wanted to do was masturbate, she could do that from the relative safety of her bed. 'I should get my sister's clothes straightened out and return to my side of the room.'

'Although...'

Lori couldn't resist. Leni's naked butt was right there begging to be touched. As far as Lori had gone already, she might as well go a little further.

With a slight tremble, Lori lowered her hand onto Leni's perfectly smooth ass and almost immediately her instincts took over again. She couldn't keep her already pussy-lubricated fingers from diving back in, this time with the addition of her palm mashing arrhythmically against her clit.

Lori was rubbing Leni's butt dangerously hard and tried to control herself from giving her a full-on massage. The fact Leni still slept was probably using up Lori's quota of luck for the year. Nevertheless, the sensation of actually feeling her this way was overriding most of Lori's ability to form coherent thoughts. All she cared about was cumming, and cumming soon.

Her wrist was going to hate her in the morning, but then Lori would hate herself in the morning too, so nothing special there. Somehow, she continued to move her arm faster, plunging her fingers deeper and harder inside herself until finally that familiar feeling started building deep within her. Lori didn't think she'd ever been so glad to achieve orgasm in her life, and certainly it had never felt so amazing.

Somehow, Lori avoided making more than a small whimpering noise while she came. She wasn't usually a screamer anyway but she certainly could have been this time.

She pulled her hand out of her panties finally, finding it covered in her girl-cum as she expected. Lacking anything at hand to wipe her fingers off with, Lori resorted to sucking them clean as best she could. She really didn't mind the taste but it wasn't anything special enough that she went out of her way to lick herself off that way most of the time.

As soon as Lori finished with her hand, Lori started on getting Leni re-clothed. Her shirt was easy enough but her bottoms took a little more effort to pull back, particularly with her sense of caution coming back. Lastly, Lori pulled her blanket back up and made sure Leni was tucked in snugly as memories came back to her of taking care of her like this in more innocent times. Back when she was the sister Leni deserved.

She sighed and stood up, not yet taking her eyes off of her sister. There were no easy options, no way to make sure she was happy. If Leni found out Lori's secret, if she left, even if Lori tried to talk to her, it could all go so badly. She was stuck with simply trying to pretend things were normal and hope that she could control herself better in the future. Lori had been doing so well until tonight.

"I'm sorry," Lori whispered even though she knew Leni couldn't hear her.

Since her panties were pretty much soaked and would become increasingly uncomfortable, Lori slid them off before collapsing on her bed. She thought she would be up a while thinking and worrying but instead Lori felt sleep claiming her almost as soon as she got settled in. That orgasm took more out of her than she thought.

. . .

"Lori! Hey c'mon, time to get up!"

Lori grumbled and only cracked open one eye to see who was waking her up so early in the morning. Or maybe not so early, the sun had already brightened the room and Lori could hear the background noises of activity downstairs. It must have just felt earlier than it was due to her lack of sleep last night.

Leni was standing beside Lori's bed, almost bouncing in frustration as Lori refused to move. After a few seconds Leni jumped on her sister's bed and started shaking her shoulder vigorously.

"What?" Lori croaked.

"Come on, mom's making pancakes and bacon and she says I can't have any until I get you up," Leni said.

As sleepy as Lori still was, she knew better than to stand between her sister and the prospect of her favorite breakfast.

"Alright, alright," Lori said. "I need to get dressed first though."

Maybe Leni had forgotten Lori's choice of sleepwear these days, maybe it was something else. Either way Leni only clued-in what Lori meant when she sat up and let Lori's blanket fall away from her chest to reveal her bra. In one swift motion Leni was off the bed and digging through Lori's shirt drawer.

"I forgot you don't wear much to bed these days," Leni said. "How about just a long shirt? You still have some right?"

"There should be a blue one there that would do. On the left-hand side I think."

Leni really had no idea what happened last night, for her it was business as usual. A small pang of guilt hit Lori as she watched her from her bed and remembered what she looked like with her pajama pants pulled halfway down her legs. It wasn't nearly as bad as she expected though, maybe because Lori wasn't really focused yet.

Leni soon held her hand up in triumph and tossed Lori the balled-up shirt. It was one of the few night-shirts Lori still possessed since she didn't wear them to bed anymore, but they still came in handy every now and then. She pulled it on while still sitting down and let the hem fall down past her waist when she stood up, thus hiding just how naked her lower half was.

With Lori following close behind, her sister made her way happily down to the breakfast table. She was acting so normal, and that was a really good sign as far as Lori was concerned. It meant she hadn't ruined anything yet.

She just had to make sure it stayed that way.

. . .

For a few days Lori actually managed to avoid any further ill-advised actions. The images of Leni's body burned into her brain were enough to keep her reasonably happy and to keep her thoughts off of any more exploration. Lori was however masturbating more than usual, particularly throughout the daytime, in an attempt to keep her hormones in check. This tended to leave her less horny at night when she was most likely to slip up.

She didn't completely stop getting herself off while in bed or anything. It was just such a convenient time, already lying down and relaxed as she was. Lori usually waited until she was sure Leni was asleep of course, not that she would necessarily mind if she knew what she was doing. The thing was that even if Leni was cool with knowing her sister was masturbating, it could still lead to awkward areas of discussion between them that Lori would rather avoid. It was safer just not to be caught.

Unfortunately, one night it just wasn't working for her. It happened sometimes that Lori just couldn't reach orgasm and, while not a huge problem in some ways, it did tend to leave her sexually frustrated. That was not really a state she wanted to be in given her current circumstances.

She tried various techniques from gently finger-fucking her pussy to frantically rubbing her clit until her wrist got tired. She even stumbled out of bed long enough to grab her vibrator which usually did the trick. All Lori got for her efforts was sore and increasingly annoyed.

The worst part was Lori knew exactly what she could do to get the stimulation she needed. Leni was snoring softly in her bed and definitely asleep enough for Lori's purposes by now. It would kind of defeat the whole point of what she'd been doing, it seemed that her plan may in fact have backfired on her. Lori unintentionally worked herself up instead of calming down and she was left without many options. When she thought about it, Lori really only had two choices; give in and take advantage of her sister again or restrain herself and suffer through a long and possibly sleepless night.

'Maybe if I could just distract myself with something I would drift off. I could probably go down into the living room and put the TV on quiet enough that I wouldn't wake anyone. It might mean falling asleep on the couch but that wasn't really a bad trade off compared to not sleeping at all,' Lori thought to herself.

She didn't even make it off her bed before pausing, barely having thrown off her covers and swung her feet onto the floor. TV wasn't what Lori wanted. What Lori wanted was lying directly across from her.

Almost in a trance, Lori stood and walked over to Leni's bed. She gotten away with it once, she probably could again. Even as Lori made the arguments in her head, she knew she was in trouble. She was trying to rationalize and she wasn't resisting very well either. Is this how it was going to be, easier every time until something finally went wrong?

Leni actually had a corner of her blanket tucked under her arm which took a little bit of prying loose but Lori soon had it piled up at her feet. Lori wondered if Leni had taken after her and started sleeping in her underwear whether that would have made things easier or harder on her. Idle musings weren't getting Lori anywhere though, and as long as she was going to go through with this again she should probably be as quick as possible.

With her recently gained experience, Lori found it much easier getting her sister's pajama pants partway down her legs than last time. Partly that was because she wasn't quite as worried about Leni waking up since Lori was a little more familiar with her tolerances. If she had been on her back, Lori might have gone for her shirt too, but it didn't seem worth the effort with her lying on her stomach again.

As with last time the sight of Leni's naked ass was enough to nearly hypnotize Lori. This was what she needed. Lori moved her hands simultaneously; one to her pussy and the other to Leni's butt, stroking both of them eagerly. It was kind of like a sexy coordination test.

With all the futility of her efforts so far, Lori was glad to feel the increased arousal provided by her unwitting sister and to sense that it was working. She wasn't yet near orgasm but it would come, somehow Lori knew it would.

It wasn't long before her exploring fingers tracing Leni's skin led her to notice a change in her position. Leni was mostly lying the same she had been last time but with subtle differences. Notably Lori discovered that she had better access as she slid her hand farther down between Leni's legs. She didn't go too far at first but Lori started to wonder if she could actually get to her pussy.

'I shouldn't of course, I should just be happy with what I had. Already I had gone much too far and pushing more was just...'

Actually there really wasn't any reason Lori could think of why it would be any worse. She was already completely fucked, figuratively speaking, if she got caught. How exactly were the consequences going to get any worse?

Slowly and very carefully Lori slid her hand between Leni's legs. It took Lori a second or two to actually realize when she was touching her pussy since it seemed to be completely smooth. Lori kept her pussy shaved pretty much constantly just because she liked the feel of it when she was playing with herself, but she never even considered that her sister might do the same.

Lori ended up not being able to get entirely underneath her, but far enough at least that she could almost cup Leni's pussy in her palm. It was such a high, touching her where she was, more so even than her ass had provided. Lori's long-awaited orgasm was fast approaching and happily concentrated on achieving it as fast as she possibly could.

If she had been a little calmer, Lori might have seen the warning signs of her sister waking up.

"Lori?"

She heard her name spoken in a confused voice and for half a second she was just as confused where it had come from. Then she understood and experienced a moment of absolute, pure terror.

"Leni?" Lori said, knowing full well it was even before her lips could move.

Lori's mind was racing through possibilities but there really was no way to disguise what she was doing. Caught with her hand down her panties? That was doable. Caught with her other hand on her sister's pussy? Completely fucked.

"I'm sorry," Lori said, repeating what she had whispered to her the last time. "I'm sorry. I'm just..."

She couldn't even think of anything else to say, what else was there? Lori pulled her arms back to her body, hugging herself as if it could bring some comfort. She was shaking all over and felt very close to tears. Even though Lori had gone through the risks in her head previously, she was completely unprepared for the reality of having to face them.

Lori couldn't decide what to do, whether to run and just get as far away as she could or maybe just curl up in a ball and close her eyes. It didn't really matter though since she was frozen in place and couldn't seem to gain any kind of motor control.

"It's okay, Lori," Leni told her.

Leni had pulled her pajama bottoms back into place and sat up, allowing Lori to see her face more clearly. It was still unreadable to her in her state but she was pretty sure she already knew what Leni would be thinking. Leni reached out to Lori and she flinched away.

"No it's not," Lori said, shaking her head. "It's not going... it just isn't."

Even before Lori finished, Leni's hands were on her, pulling Lori toward her until her arms could wrap around her big sister. It was such a bizarre thing for her to hold Lori that way given how she should be acting. Whatever that might mean Lori didn't really think about it. Mostly she just cried.
