I woke convinced I'd dreamed the events from the night. I knew how hard the previous day had hit me emotionally, and though I still had no answers about my son and daughter's 'games,' I utterly dismissed the words which had penetrated my consciousness as the disconnected ramblings of my overactive imagination set free during a time of stress and anxiety.

My son had called and left a message that he was staying with his friend that day and wouldn't be home until Sunday. I was somewhat relieved, honestly, because I had no idea what to say to him. I couldn't get images out of my head of him holding my daughter's panties, his own sister's scents and wetness in the crotch, while he masturbated. I could almost hear him cumming, shooting his semen into Kira's underwear. I couldn't help seeing what my daughter would do with the creamy load he left there for her, tasting it with her tongue, playing with herself as she ate her brother's incestuous sperm.

I tried to clear those thoughts and found myself feeling rather unwell. I went to the kitchen and made coffee, no sign of my daughter early in the morning. For that, too, I was thankful. I knew I needed to talk to Kira further, but I had no idea what to say.

My daughter came down from her bedroom just before noon, looking weary, wearing her pink and white pajamas. I noticed that she wore no bra, as was usual at home, and Kira's breasts had grown large enough that the old top was tight and clearly showed my daughter's dark areolae and nipples underneath. I looked away quickly and offered to make her lunch. She grunted an acceptance and sat at the table without another word.

I leaned against the counter while she ate, stewing over what to say. I don't know what finally made me ask, “Kira... are you still a virgin?”

She choked on her toast, swallowing orange juice for a moment before she was able to catch her breath. “Yes...” she finally stated softly.

“Okay...”

Then I realized something else, and I probed, “so... this mystery boy... the one you thought you might need birth control for... you were talking about your brother, weren't you?”

Kira stared ahead, her hair down over her shoulders, somewhat blocking my view of her face. After a moment of silence, she shrugged, and looked down at her plate. “I don't know.” I'd come to recognize that as Kira's affirmative response to a question which was uncomfortable or embarrassing.

“Have you and Dex... talked about this?”

“No! No... we've just... you know... done the panty thing...”

“So... he's not asked you to show your body to him, or... pressured you to touch him?”

Kira shook her head, looking in my direction but past me. “No, Mom... no... we never really talk about anything like that, just... he gets my panties and I get them back, sometimes... that's it...”

“But,” I replied, “you've considered what it might be like... doing something more?”

She shrugged again. “I don't know...”

I sat at the table and took Kira's hand, running my thumb along the top of her fingers. “It's okay to be curious, Kira. We're all curious sometimes, but... Dexter is your brother... I know it might not make sense but you can't explore that with him...”

“Because it's wrong?” she said softly.

“Yes, it's wrong.”

“Why?” came her quiet response.

“Because... because... you just don't do that with your family. You just don't.” I couldn't really formulate words which expressed exactly why it was wrong. Something tugged at my memories, something buried deep, something which tried to bubble into my thoughts but was too-quickly washed away. “Because... just because...”

Kira said nothing, staring beyond where I sat. She looked at me a moment, her eyes searching mine, before she looked away again and said meekly, “so... what we do... it's wrong, isn't it? We're bad people...”

“No,” I replied without thought, “no... don't... don't think that, Kira. No, you're not bad, just... curious.”

“So if we're not bad for doing it... why is it wrong?”

“Because I said it's wrong, that's why,” I stated, frustrated by my inability to come up with a much better reason. “Because... you're brother and sister and... you don't do those things together...”

“We aren't hurting anyone...”

“No... I know...”

“And... I like it, Mom... Dex does too... not like we're fucking...”

“Kira Marie Peterson! Language!”

“Sorry,” she said, sounding less chastised than I'd have liked, “but it's true... we're just... playing.”

I sat silently a moment. I finally managed to calm myself and said, “Listen, Kira... I just think it's wrong for you and your brother to know each other that way. Your body and his are private things, and the way you share... intimate parts of yourselves with each other... it crosses a line... He shouldn't know what you smell like... down there, and you shouldn't be... doing whatever you do with his ejaculate...” Scenes of my son cumming in Kira's panties exploded in my head, and despite my revulsion, I felt myself growing wet.

I shuddered involuntarily, and Kira eyed me a moment, seeming to notice the way I'd grown flushed and sweaty. It was all I could do not to yell at her, mostly out of my own guilt. I managed not to do so, instead saying calmly, “it's okay that you're curious, Kira. It's okay... you and your brother are not bad... and... maybe it's not wrong in the moral sense... I'm just... very uncomfortable, okay? I worry where this will lead if you and Dexter keep this up...”

Kira's expression was solemn but stubborn as well. “What will you say to him, Mom?”

“I don't know,” I said, meaning it honestly. “I can barely manage to talk to you about this...”

“Mom... I'm sorry he took your panties, okay? I never thought he'd do that... I thought... he just liked mine... I guess he likes yours, as well...”

“So it seems...” I said, resigned to the truth, “and that just makes it all the more difficult...”

“I won't let him have mine again...”

“I'd like to believe you, Kira.”

“Not if I can help it... but... sometimes... I just get... you know... excited... not like I have a boyfriend or anything. I don't have a guy who likes me or thinks I'm sexy...”

“Oh, Kira, I doubt that is true. I'm sure your classmates think you're great, you're just kinda shy with them. Maybe they think you don't like them.”

She nodded. “Maybe I don't...”

“What? Why?”

Kira frowned, “because it's true...”

“But... but you like... your brother?”

She shrugged, “maybe...”

“Oh, Kira...” I massaged her hand a moment, not knowing what to say. “Promise me... this won't lead to more, alright? That this... game... won't become incest... promise me...”

Her tone was not convincing. “I promise...”

- - -

I napped in the late afternoon, so tired from the stress and emotional moments that I was unable to talk to Kira further, and I mostly wanted to avoid her and keep to myself. Thoughts of what my kids were doing, even if it wasn't physical incest, left me distraught and confused, and I was unable to separate my disgust from my own curious arousal. I drifted in and out of sleep, vivid dreams of my daughter licking my son's cum from her own panties had my cunt soaking in my underwear.

Remember what we did, Penelope?

I barely registered the words, again unsure if they were spoken or just imagined. I listened a moment, responded softly, “what?”

Remember what we did? You and me?

The soft, feminine voice brought familiarity, a distant recognition which didn't quite surface. “Who are you?” I said quietly, unsure if I was dreaming or hearing voices in my head.

Don't you remember, Penelope? Don't you remember me?

“I... I don't know...”

I remember it all. Like that time we shared a shower? That was one of my favorites...

“A—a shower?” I felt a burning start in my stomach, something stirring my thoughts. The memory was blurry, disconnected, lost in something I'd tried to forget.

You were so sweet, Penelope. I loved you so much.

“Loved... me? Who are you? What do you want with me?” I couldn't help feeling I knew the voice, or what passed for a voice in the words which came to me.

It seemed a sad smile might have formed the response. Don't you remember your own sister?

My pulse raced as memories flooded into my brain and I squeezed my eyes quickly shut as the long-lost images rushed in with the force of a freight train.

- - -

“Hurry up!” Jackie took the shampoo from me as I tried to quickly rinse the suds out of my eyes. “Mom and Dad will kill us if we make them late.”

“I know, stop hogging the water!” I pushed my sister gently, trying to get more of the flow.

Her breasts brushed against my arm and instead of being angry, she purred. “Easy, Penelope... you know I like that...”

I narrowed my eyes just out of the flow of water, “oh, I know... and I know you like this!” I thrust my hand between her legs. She tried to clamp her thighs tight but I was too quick.

Jackie pretended to struggle as she slid her genitals along my arm. “You're going to make us late...” she said without conviction between light moans. My sister started to hump my wrist, her hard clit rubbing along my skin. The water washed over her body as she leaned against the back of the shower, closing her eyes. I moved my fingers forward and slid one into Jackie's vagina. She purred and I crouched low, using my other hand to caress her clit.

She bucked quickly, using one hand to cover her mouth. Our parents were in the next room, getting dressed for church. I tried to shush her to be quiet, but I couldn't stop touching her body. Her legs started to shake and she jerked forward several times, her muffled moans too loud but we were too far gone to slow down.

Jackie came on my hand, rolling her hips around where my fingers probed her tender flesh. I pulled back only when she grabbed my arm and physically made me stop. I rose and my sister wrapped her arms around my shoulders, hugging me. “I love you, Penelope.”

“I love you, too.”

“I have to give you one before we leave.”

Her fingers slid between my legs and I closed my eyes.

“Hurry up you two!” My dad's voice boomed from the doorway. Jackie's fingers were snatched back. I could tell our father had opened the bathroom door and was leaning in. I was tremendously thankful that we had a dark curtain liner covering our bodies. “Let's go. We're going to be late!”

“I'll give you one later,” my sister whispered to me with a smile when our Dad closed the door again. “I promise.”

- - -

“NO!” I yelled out loud. “How dare you!?” The voice had slammed into my brain a vivid memory I hadn't held in my mind in many years. I'd long-ago repressed thoughts of my sister, long-ago shut off memories of her and what we'd done. I refused even to think about what had happened to her, refused to let the voice draw me back to the horror and sadness that had taken her from me.

I'm sorry, Penelope. I want you to remember me again. I want you to know it is alright to remember.

“How dare you!?” I repeated, yelling again. “That is my memory. Mine! What madness is this?” I was certain I was hallucinating, wondering if I had been poisoned or suffered from a brain tumor. I felt very dizzy and lay back on the bed, my arm held over my eyes. “Leave me alone! Just... leave me alone!”

“Mom?” Kira's voice called from the hall. “Mom, are you okay?” She sounded concerned.

I didn't respond at first, and I heard the door open. I still held closed my eyes.

“Mom? What's wrong? What is it?” I felt my daughter sit on the edge of the bed, her hand on my leg. “What's wrong?”

“Nothing,” I finally said firmly, trying not to show how scared I was of my own insanity. “Nothing, just... just a nightmare, that's all.”

“A nightmare? Mom... you were yelling...”

“I know,” I said, slowly calming myself, “just... just woke from a nightmare... I'm okay... really.”

Kira stroked my thigh sympathetically. It made me flash back to my sister's touch from so long ago. I jerked from Kira's hand and sat up on the bed. “Sorry,” I said, “sorry... I... It was just a nightmare...”

She looked hurt, and I tried to smile, probably doing little to ease her concerns. Kira replied quietly, “okay... I just worried... are you hungry? I made dinner...”

I closed my eyes a moment, unable to clear the memory, and then I felt myself grow calm and my head cleared. The memories faded, and for a few seconds, I tried to remember what had caused me grief. It was lost as I stood slowly. Something lingered on the edge of my mind, something full of both pain and pleasure, but whatever it was receded and left me feeling lost. “Yeah... yeah, I could eat.”

I moved around to where Kira stood from the bed and hugged her tight. “I love you, Kira.” I felt the need to hold her and affirm that I needed to be close to my daughter a moment. “No matter what.”

“I know, Mom. I love you, too... you sure you're ok?”

I smiled, the grief and uncertainty fading with whatever the nightmare had brought into my mind. “Yeah, I'm fine. So, what's for dinner?”

- - -

Kira went to bed before I did, and I spent a couple of hours staring blankly at the television after she disappeared upstairs into her room. I was still unsettled, couldn't recall what had so upset me that afternoon. I didn't like having holes in my memory, in my emotions, and whatever it had been left a remnant of powerful experiences just out of my grasp. No matter how much I thought about it, nothing was forthcoming.

I finally turned off the television and the lights, and tucked myself into my bed, pulling the covers up to my neck. I settled on my back, staring at the darkness above.

I know it hurts, Penelope. I'm sorry. It hurts me that you have forgotten.

I was confused again, vaguely remembering hearing that voice before. I recalled it from the afternoon, and the night before. That familiar voice somewhere between my ears and my brain. “Jackie?”

It hurts to remember some of it, Penelope, but there was a lot of good, too. I want you to remember that.

“I don't remember,” I whispered, certain my grip on sanity was growing loose and that I was talking to myself. “I don't want to remember.”

But you need to remember. I'm lost if you don't believe that remembering the good times is worth also remembering the bad...

“The good times...”

After the first night we played together. Don't you remember? At the lake?

“No...”

I'll help you...

- - -

It was so hot that day that I had to stay in the lake water to keep from overheating. Jackie was nearby, swimming and singing to herself. Our parents had gone back to the cabin in the heat of the early afternoon, leaving the two of us by ourselves, though other people were around, some swimming, others laying out on the beach, some cooking over grills or drinking wine and beer.

I was confused about the night before. My sister and I had crossed a line in those moments, knowing sexual intimacy which no siblings were supposed to share. I knew, in some ways, that it was just innocent play, but it had been the first time I'd let anyone do that with me, and I was ashamed to have enjoyed those moments with my sister. We hadn't talked about it that day, but I couldn't help feeling the mix of guilt and arousal for what we'd done.

I caught Jackie looking at me fiercely as I rose up from the water a moment to push the hair from my face and neck. Her eyes drew down to where my breasts had risen and were well-covered by my swimsuit. She looked away, back towards a group of three boys who I'd seen laughing a few minutes earlier. I caught one of them glancing my way, staring at me a moment before turning back to his friends.

“They think you're hot, you know,” Jackie said to me, moving closer. “I can tell.”

“They're probably just looking at you. You're the hot one, not me.”

“Bull,” my sister said, “you're totally hot, Penelope. And those guys noticed.”

I looked away from her, “doubt it. I'm just plain.”

“Bull,” she said again, “you're pretty and you have nice boobs. Seriously, Sis. Don't doubt it. You're hot.”

I shrugged. “Whatever. What's your point?”

She looked back at the boys, then said, “I could go talk to them for you...”

“What? Why?”

She turned to me, “you know, in case you wanted to fool around or something.”

“Jeez, Jackie...” I blushed.

“Just playing. You're old enough, though. I was fooling around with boys at your age. It's fun!”

“Yeah, well... you're the hot one. Guys like you. I'm just... not you.”

“Come on, Penelope. Let me go ask.”

I didn't respond and she took that as her cue to swim over to where the boys were watching her approach. I pretended not to see them talking, Jackie laughing with them as she got closer. I saw her point to me quickly and two of the boys looked my way. I blushed and looked elsewhere, sinking in the water to hide my embarrassment.

Jackie swam back, “okay, here's the deal. I just told them that maybe we should all hang out later. Nothing more than hanging out,” she added quickly when she saw me about to protest, “you don't have to fuck them.”

“God, Jackie... I don't know...”

“I'll help you. I promise. And yeah, they think you're hot. Trust me.”

“How do you know?”

“I asked.”

“You what!?” I demanded.

“I asked if they thought you were hot. They all did.”

I had felt very self-conscious about my body since I'd started developing a year or so ago. I hated that my breasts were obvious under my clothing, hated that one was really pointy, the other a little more round. I knew everyone could tell, and it made me doubt myself whenever I couldn't completely hide my form. I knew my hips had spread, my butt pushed out, and no matter how often I washed it, I could always smell my pussy whenever I wore a dress, which I had done only rarely since becoming aware of my own odors.

I grudgingly agreed I'd give it a shot, but I felt dread in my stomach, nervous that I'd have to interact with boys I didn't know while my hot sister stole the show and made me look like the little girl in the group.

We planned to meet them after dinner near a more private area on the side of the lake. Jackie and I ate with our parents and asked permission to go swimming again afterwards. My mom had demanded we be back before dark for dinner and we were not to be talking to boys. Our parents were very strict on that, but my sister was well-practiced at telling them what they wanted to hear and then doing what she wanted anyway, without getting caught. They had never known about her boyfriend despite the fact that Jackie had managed to meet him several times over the months for sex.

I was undeniably jealous of Jackie's charisma, of her comfortable conversations with boys, of the way she looked so sexy no matter what she wore. She smiled and looked into boys' eyes, leaned in when appropriate, and made it known that she liked to talk about sex whenever she could. It made my shyness and introversion that much more stark by comparison. Where Jackie shined into any crowd, I felt like a black swan in a pond full of golden geese.

We met the boys a couple of hours before sunset. I'd put on a t-shirt and a pair of knee-length shorts, my bra and panties underneath were yellow cotton. I did my best to think that I looked attractive, but mostly I was just trying to cover my body with the loose-fitting clothing I knew would do little to reveal my maturing curves.

Jim was sixteen, tall with short blond hair. Martin was a short, dark-haired fifteen-year old with curly locks over his eyes. Brad was also fifteen, long blonde hair tied in a pony tail and sporting a rough beard and mustache, making him look tough and much older. They greeted us with cheers as we walked up.

“This is Penny,” my sister said, using my more common name in a rare instance, “my sister. Isn't she hot?”

I was mortified, frozen in place.

“Hell yes,” Brad said immediately, “you both are.”

The other two nodded and grinned.

Jackie turned to me, “see? Told you.”

I was blushing furiously and wished I could slip away before it got worse. My sister put down our beach towel and I quickly sat on it trying to avoid eye contact.

“So, we've got some beers, you two want?” Jim asked.

Before I could shake my head, Jackie replied, “of course, and so does my sister.”

I'd never so much as tasted any alcohol, and I didn't know if Jackie had either. I was so afraid of my parents finding out that I didn't even open the can until it was warm in my hands. Jackie had finished half of hers in a couple of gulps. “Drink up, Sis.”

I didn't want to appear to be as scared as I felt, so I slowly popped the top and took a sip. It was disgusting and I almost spit it out. I managed to swallow it without throwing up and gave my sister a weak smile. “It's good,” I lied.

“So what are you boys up to tonight?” Jackie asked, taking another long drink from her can.

Jim shrugged, “hanging. Night's still young...” he stared at my sister in a way which suggested he wanted to do more than hang out.

Jackie giggled and replied, “so it is. Know any dirty jokes?”

Brad offered, “sure.” He grinned. “What do the Mafia and pussy have in common?”

Jackie shrugged, “what?”

“One slip of the tongue and you're in deep shit!”

The boys laughed and I pretended to get it. Only later would I understand the connection. Jackie shook her head. “That's terrible!” She looked at me smiling, then turned back to the boys, “why do guys like big boobs and a tight ass?”

Jim replied, “why?”

“Cause they have big mouths and tiny dicks!”

I laughed when I got it, and the boys looked a bit put off even as they chuckled. Brad spoke loudly, “some aren't so little, you know!”

“Maybe so,” Jackie said, “don't need proof!”

“I got one,” Martin added, “what do you call a teenage girl who doesn't masturbate?”

I felt myself dreading the answer.

When everyone shrugged, Martin smiled and said, “a liar!”

I tried to make myself smaller, self-conscious about the subject in front of others. Sure, I masturbated, but I didn't feel comfortable even joking about it with the boys present.

Martin wouldn't let it drop. “So, are you a liar, Jackie?”

“Hardly,” she said back, “proud of it, actually.”

I could see him licking his lips at the image.

Brad looked at me, “and you, Penny? You a liar?”

“I...” I found myself unable to say anything further.

After a pause, the boys started to laugh. Martin said, “yep, she's a liar. We know you let your fingers do a little walking, right?”

I shook my head, feeling very uncomfortable.

Jackie saved me. “Easy, pervs, that's my sister you're talking to. She's fourteen. Cut her some slack.”

“Aw, come on, Jackie,” Jim pleaded, “just having fun. This is what you do at the lake, talk about sex and such, then later... you know.”

Jackie looked at me more seriously a moment, and I knew she saw the fear in my eyes. “Yeah, well, not tonight, there's no... 'you know,' for us. Just hanging out, thanks.”

Brad smirked, “oh, I think a couple more beers and that might change. Like I said earlier, some of us aren't small.” He started to rub his crotch and the other boys laughed loudly. “Maybe you would like some proof.” Brad stared at me menacingly as he started to pull down his swim trunks.

“No, please,” Jackie said, putting her hand up in a stop sign. “We're not here for that. Just stop, give us a break.”

Jim laughed loudly, “tarts! Just a couple of tarts. What? I'm sure you've seen a dick or two, Juicy Jackie.” I turned back to see that Brad's pants were down, his penis out and hard. He was looking at me. I was horrified. Jim laughed again, “look at her face! First dick, Penny? Ever seen one before?”

I averted my eyes, blushing deeply.

“Back off, guys,” Jackie growled.

“Aww, don't be shy,” Jim said, “I'll show you mine if you show me yours.” I knew he was talking to me.

I felt sick.

“Goddamn, screw you guys. We're done here. Come on, Penelope.” Jackie stood quickly and I was right with her. “We're not fucking you, we're not sucking your dicks, and we're not showing you our boobs, as fantastic as they are. Jesus, couldn't you just give it a rest and act like decent guys for five minutes? I haven't even finished my beer and you're being jackasses!”

She turned her back on them, snatching up our towel, and I followed as she marched off to the other side of the beach area. One or two of the boys catcalled us as we left, alternating pleas to come back with sexual descriptions of our backsides and what they'd do with them. Once or twice, I heard them making fun of me. “Peniselope,” and “little Pussylope,” and “she's probably a stupid virgin.” I felt so ashamed.

We ducked into a secluded spot far enough away that we felt they wouldn't come over to us. Jackie sat the towel down and turned to me, putting her arm on my shoulder. “I'm sorry, Penelope. I know guys act like that sometimes... and... usually, I can handle it... you didn't need or deserve that. I'm sorry. That wasn't nice or fair.”

“It's ok... just... embarrassed. I hate my name...”

“Don't ever say that!” Jackie hissed at me. “Never. I love your name. It's pretty and classy.”

“Whatever...”

“I know. Look, let's just hang out here and have some girl talk without those assholes, sound good?”

“Yeah. I'd like that.”

She stretched out on the oversized blanket and I sat next to her, shaking a bit from the events moments before. “It's ok, you know,” Jackie said.

“What?” I replied.

“Masturbating. I do it, I know you do, too.”

I said nothing.

“It feels good, right? Like, why wouldn't you do it? I know mom and dad preach about how sinful and wrong it is, but, jeez, lighten up. I can touch myself if I want.” She saw me blushing again, and said more softly, “it's ok, Penelope. Really. I wish you understood how pretty you are, how much you hold yourself back because of your doubts. Those guys were assholes, yeah, but there are good guys out there, too, and you deserve to know a few of them. You gotta learn to love yourself.”

“I try. I just... I don't know, Jackie. I feel... awkward.”

“Everyone feels awkward. You're at that point, just starting to get your boobs and your butt and all, starting to like boys, starting to see other girls who you think are hotter, and you're doubting yourself. Don't do that. Don't compare yourself to them. You're beautiful. I wish you could see that.”

“I try,” I repeated. “I just... I don't know.”

Jackie was quiet a moment, then said softly, “I really liked last night... what we did together... I know it was odd... we're sisters and all... but it felt good, and... I really liked it...”

“Me too,” I admitted quietly, “me too.”

She put her hand on my back, just holding it there. “Can I touch you there again? Make you feel good?”

“Yes...” I said despite my nerves.

“Lean back...”

I did as she directed and my sister slid beside me, her hand running over my shirt a moment. “I really love your boobs, Penelope. Really... they're perfect...” Her fingers traced the edge of my collar then moved down to my stomach, sliding under my shirt and tickling my abdomen. I jumped involuntarily. “You always were ticklish. I promise I won't... that's not the reaction I want right now...”

Her fingers touched my bra and I felt my sister squeeze my left breast lightly, then again. With two fingers, she unsnapped my bra from the front, and it fell down my sides. Her hand slid over my smooth, firm tit and I saw on her face that she was staring at my covered body, her mouth slightly open. I moaned without thinking.

“Can I see them?” Jackie asked me quietly. We'd seen each other's breasts many times over the years, but never had she expressed any interest in mine beyond a joke or two as they grew in. “I'll let you see mine...”

“Yeah...” I raised up slightly as she pulled my shirt over my head, my bra falling under my back, my pale tits small enough to stay in place, moving up and down as my breathing quickened. I was caught up in her light touches as she slowly worked her soft fingers along the undersides of my breasts, a smile on her face.

Jackie purred, caressing my flesh, and my nipples responded by hardening to her touch. “Lovely. You have such nice boobs, Penelope... so nice... Here... relax...”

My sister leaned over me and kissed my lips again, sending excitement racing down my body. I felt my clit tingling and rising. Jackie moved down my neck, teasing it with her mouth, her fingers working first one breast then the other as if she really enjoyed touching them, her touch gentle and careful. I moaned again as she took one of my nipples between her lips and sucked lightly.

I gave no thought in those moments to who was exploring my flesh. Sure, I knew it was my own sister, that Jackie was tasting my skin and touching me in places that only I had touched, that only I had explored so directly. One of her hands slid down over my stomach, making me shudder. She purred as her fingers slid to my waist.

“I can stop, if you want... but I'd really like to touch you again... down there...” Jackie's hands were silk gloves against me, and I don't think I could have said 'no' if I wanted to. Her skin felt so good on mine, her touch so gentle and warm. I didn't want her to stop, and I watched as she unbuttoned my shorts and laid open the top, her fingers moving down over my panty-covered crotch.

My eyes closed as her hand massaged my Mons a moment, my sister's fingers barely teasing the private flesh below. I was turned on beyond anything I'd ever felt before, even more so than when we'd played our game the previous night. My thighs parted automatically as she pushed my shorts down and off my legs. I stared at her, hungry for her attention, unwilling to consider what I was letting my sister do with my body.

Jackie kissed my boobs while her fingers explored under the waistband of my cotton panties. I started to rock slowly as she worked further into my crotch, her hand moving over my pubes, teasing my maturing slit without touching it. She sucked in my nipple again, and pressed her body against mine. I could feel her tit against my side through her shirt. My sister wasn't wearing a bra, and her lovely breasts felt warm and wonderful against me.

Fire burned between my legs, and then I felt shards of icy pleasure rip through me, starting where Jackie's fingers grazed my erect clit. She lingered there a moment, moaning softly as she kissed my stomach, her lips trailing slowly along my flesh. My genitals felt swollen as her hand slid through my slit, gently slipping along my most sensitive folds. My sister whispered “you are so wet...”

My labia parted as Jackie slid one finger between, nestling it just inside the entrance of my pulsing vagina, her palm slowly rubbing against my clit. She probed me slowly, not going too deep. I felt her push against my hymen and I flinched automatically, my thighs squeezing, her hand trapped a moment between my legs, “no!” I said strongly, breathing hard, “please don't break my cherry...”

“I won't,” she said kindly, “I won't. I just love being inside you, Penelope... I won't break it. Just relax...”

I felt her draw back just a bit, her finger still nestled in my tender hole, her hand working small circles across my sensitive flesh. I was getting very close and could feel my body reacting on its own to my sister's wonderful attention. I let out a low moan as she alternated stroking my clit and probing an inch or two into my vagina.

“That's it, Penelope... let it happen... let it happen...”

I tensed as my body became overheated. I was sweating, my skin aflame, my mind lost in the pleasure of my sister's fingers. My hips rose and she pressed harder against my clit, circling it. My thighs clenched and relaxed, my butt rising from the towel. “Oh... ohh... ohh...”

I knew I was there, and Jackie knew it too. “Cum for me, Penelope... cum for me...”

I exploded in a thousand directions at once, unable and unwilling to stop my cries of pleasure. I heard them echoing in my ears, as if from some other girl. I felt my vagina clenching around my sister's finger, my clit burning against her palm. She kissed my stomach as I writhed and shook, my hands suddenly running through her hair, holding my sister's head against my body. I came and came, lost in the sensations, my pussy drooling into my panties and over Jackie's flesh. I felt pleasure rush in as my channel flooded, my nipples almost painfully hard, my clit withdrawing rapidly as it became sensitive and sore. I clamped my thighs together, bucking against my sister's hand, whimpering as the intense moment only slowly fell away and left me feeling weak and wonderful.

Jackie nibbled my skin, planting soft, lovely kisses on my stomach around my navel, her fingers held gently over my crotch. I knew she could feel me trembling, and for long moments, I was unable to do more than shiver and hold her head against my body. I felt amazing.

It started to creep in what had happened, and my puritanic upbringing started to push back my pleasure and replace it with guilt. Jackie, as she always seemed to, was ready to battle those thoughts. “That was wonderful, Penelope. Just wonderful. What could be more perfect than sharing that together?”

“But... you're my sister...”

“Yeah, and you're mine. We should be able to do that for each other... isn't it better to share the good times together? To share happy moments with one another?”

I shrugged, a mix of pleasure and shame sitting in uneasy alliance in my mind and body. “Maybe...”

“Didn't you enjoy that?” she whispered.

“Yes...”

“Me too. I loved making you cum like that, Penelope. If I could, I'd do nothing else in life than play with your pussy.”

I had to laugh. My sister loved to curse and use words my parents would never allow, and I'd always found it funny to hear her say 'pussy.' She always managed to pronounce it as if it was a magical thing, something sacred, her breathy tone always making me smile when she said it that way. “I don't think Mom and Dad would let you do that...”

“Screw them,” Jackie said, finally pulling her hand from my panties. I jerked involuntarily at the rapid loss of her warm flesh from my genitals. “They'll never know, and what we do together isn't their business. We're both old enough to make our own decisions, and I want to share this with you all the time, Penelope. All the time...”

“Okay,” I said, starting to smile. The pleasure was winning over the shame. “I really liked it, Jackie... I... I've never had one so strong before...”

Jackie pulled herself up to put her lips just inches from mine. She had a wonderful smile on her face. “I'm so horny right now... Would you touch me?”

Before I could respond, we heard laughter from somewhere close by. I jumped up and raced to put my shirt and shorts back on. Jackie was beside me, helping as best she could. More laughter, closer this time. It sounded like the boys.

We stood a moment, listening. I was frightened, honestly, both by how I'd been embarrassed earlier and by how I felt naughty for having orgasmed with my sister touching me. I didn't want to see anyone in that moment. Jackie whispered to me, “come on, we should go...”

I followed her behind the bushes and we made our way indirectly back to the cabin. I could feel my pussy drooling into my panties, and that did nothing to make me feel comfortable when our parents greeted us inside the cabin. I never got a chance to get Jackie off that night as she fell asleep an hour later on the couch watching a movie, and I went to bed alone, my thoughts moving from arousal to shame and tinged with a great deal of confusion and curiosity.

You remember, don't you, Penelope. You remember.

“I... I remember.” I had no idea why I was talking to myself, one half of the conversation in my sister's voice. I knew I was insane, something snapped inside of me. I was no longer as frightened as before, memories of Jackie welcome after so long. “I wish you were here...”

I am here.

“No,” I replied, as if there was actually someone listening, “I mean... really here. I loved you so much, Jackie... You made me start to love myself.”

You deserved better than that asshole you married.

“I know... thanks...”

At least you have two amazing kids, Penelope. They are growing up so fast.

“Too fast... how... how are you here, Jackie? I... I'm just talking to myself, right?”

I don't know. I just became aware of you again... it's been so long.

“I'm insane, Jackie. You aren't here. I'm not talking to anyone but myself.” To say it sounded crazy to explain that to myself would be an understatement.

You're not insane, Penelope. I'll show you if you'll let me...

“What... what do you mean?”

Relax... I'll show you how much I love you, Sis...

I felt a warmth spread over my body. I was still beneath my covers, my hands at my sides. There was a sensation of a hot breath on my thigh, and my legs spread on their own. “What...”

Shhh... let me show you...

I became aware of a light touch, a bare tickle between my legs. I believed it was just sweat in my crotch, perhaps my perspiration from the warmth below the blanket was trickling from my Mons and down past my labia. Whatever it was, it was pleasant and I let it take me as I closed my eyes.

Your pussy was always so beautiful, Penelope. So sweet and lovely...

A softness spread over my genitals. It was if my sister's fingers were touching me there. I was sure I was imagining it, my ongoing mental crisis leading me to hallucinate that long-lost sensation. I moaned without a thought, the tingling in my clit becoming a throb.

I loved touching you here... I never cared if you touched me, I just wanted to make you feel good, Penelope...

“Ohhhh...” I breathed out softly, my clit responding to the imagined touch. I felt the hint of soft fingers running down my labia, spreading wetness along my slit. While I was no longer the virginal girl who'd once known her sister's hand there, I was drawn back to the feelings of pleasure and love those shared moments had brought me. “Ohhh...”

I never did get to finger you fully, Penelope. You saved your cherry for another. I always wanted to do this...

My vagina dilated as something pushed in. I couldn't believe how real the sensation was to me. I had to clench my fists to be certain they were still at my sides. I wasn't touching myself. My imagination, my delusion, must have been strong to feel so strongly a finger inside my body, pushing deeper and deeper into my slick channel.

Oh, Penelope... your pussy is wonderful...

“Ohhh...” The movement in and out started slowly, gently, but it became rapid, my body rocking back with each probe. I could almost see my sister watching me, fingering me. I bit my lip as my skin grew flushed, wetness sliding down over my anus as I grew excited. “Ohh... Jackie...”

That's it, Sis... cum for me... cum for me again...

My eyes closed tight, my hips rising. I knew I was imagining it all, that it was only my mind driving me towards release, but the fantasy, the vivid imagery brought back by hallucinations of my sister from so long ago had my channel spasming around where I felt her finger again. She probed me deeply, twisting and rubbing the upper side of my vagina.

I cried out in pleasure, cumming in ripples. My hands came up to my stomach, clenching into fists again, my body writhing as I orgasmed.

Oh, Penelope... oh, you wonderful, wonderful girl...

I started to whimper as waves of warmth spread through me. “Jackie... oh, Jackie...” Tears formed in my eyes even as I released. I felt her finger withdraw, no longer inside my body. I felt its loss immediately, and I sobbed. “I miss you so much...”

I know... I missed you too. I'm here now... I'm here, Penelope...

“But you're not!” I said between sobs, “I'm just crazy!”

No, you're not crazy. I can't explain it... I can't understand it... I can only find you sometimes...

“What?” I cried. The impression of Jackie's voice had grown faint, weak. “Jackie?”

I love you, Penelope, the voice said quietly, fading, I'll find you again...

“Jackie?” I called into the darkness of my room. “Jackie?!”

There was no response.

I didn't move for some time, crying softly to myself, overwhelmed by my hallucination. It had felt so real. I hadn't touched myself at all, and yet I'd had a powerful orgasm, all from imagining my sister touching my body. I wondered how far I was going to fall into my delusion. I worried what my kids would think when they found out I was losing my mind. I didn't want them hurt, didn't want them to see me so messed up. I cried into the night, inconsolable and lost and without a clear understanding of how I'd fallen so far, so fast.
