We made love together often over the following days. I let Dex cum in me whenever he wanted. I knew it was risky, that I still had my period and could get pregnant, but for those moments, I didn't want him to pull out and I definitely didn't want him to wear a condom. He and Kira made love a few times on their own while I gave them some privacy. I wanted them to get to know each other that way, without me there, though I admit I was thrilled anytime they invited me to join them.

I called to Jackie regularly, but there was no response. I was still heartbroken about her leaving, but there seemed little I could do to change things.

I sat on the couch by myself, Dex and Kira up in her bed, likely making love for the second time that day. I smiled knowing how hot they were together, how much I enjoyed knowing they were growing comfortable together, sharing every inch of their bodies with each other.

I missed Jackie terribly. I felt a hollow place inside me, one I'd covered over for many years after the accident, the hollow place filled for a few weeks while Jackie was with me again. Losing her a second time made me ache dully, wanting only to hear her voice one more time, if only to tell her I loved her again.

I thought about the first time I had gone to Jackie and made the first move, the first time I'd been sure that I wanted us to be together.

- - -

I knew something was different in this memory. When Jackie was showing me, I was there fully, a participant unaware of my older self watching the scene. This time, as I looked out from my fourteen-year old eyes, there was an extra layer there, a knowledge that I was directing someone to see what I saw. It made Jackie feel real to me yet again, not just as a memory.

“Jackie,” I said, knocking softly on her door, my panties wet from where I'd been playing with myself moments earlier, “can I come in?”

“Yeah,” my sister replied.

I stepped into her room and closed the door behind me. She was on her back on the bed, reading a novel, wearing the pair of reading glasses she hated so much. They had a dark, narrow oval frame and I thought they were cute on her. I had even bought a pair for myself a few weeks earlier, but after checking myself out in the mirror, I didn't like the way I looked with them on. Plus, I didn't really need reading glasses, they were just another way to try to capture some small part of my sister's beauty for myself.

“Hey,” I said quietly.

“What's up?” Jackie said, closing the book in her lap.

I shrugged, “just wanted to spend some time with you...”

My sister smiled at me, “okay... anything in particular you want to do?”

“I... I dunno,” I said, sitting on the bed at her feet.

“You don't know?” Jackie replied, “everything okay?”

I nodded, “yeah, just... was thinking about you...”

“Oh?”

“Yeah... just... been thinking... about you...”

“You said that already,” Jackie stated, “out with it.”

“I... I want you to touch me...”

“Oh, this is getting interesting...” Jackie purred.

“Just thinking that might be fun...”

“I'm sure it would be fun, if that's what you want, Penelope.”

“I do,” I said, looking at where my sister's shirt hung down low, the slight curve of her small breasts visible below the neckline, “I... I'd really like that again...”

Jackie scooted next to me and put her arm around my shoulder, “look, Penelope... I don't want you to think you have to, okay? We were just having some fun. You sure you... want me to touch you again.”

I leaned into her and kissed her neck lightly, “yes... please... I'm so wet...”

Jackie purred and kissed my lips, then pushed me back, her hand sliding down to my thighs. My sister's fingers slipped over my panties and she grinned against my neck, “mmm... you are wet...”

She slowly slid my underwear down and brought them up, holding them over me while she looked at them. I had worn a pair of green panties and the dark spot in the crotch gave evidence of my arousal. I could smell them as Jackie turned them over in her fingers.

I saw her inhale and smile, then she brought the panties to her nose and sniffed them. I wasn't sure what to think. I certainly found my own odors embarrassing. Since I'd started puberty, I'd been aware of the smells between my legs, and I worried constantly that others would notice them, as well. A year earlier, I often wore two pairs of underwear on the days when I thought I had the strongest odors. Watching my sister intentionally sniff the wet crotch of my panties over and over, I couldn't help cringing to see her suck in the odors I'd tried hard to hide.

Jackie surprised me. “God, Penelope! You smell so fucking amazing.”

“Really?”

“Oh, absolutely! Mmm...” She sniffed my aroma again, then rubbed the wet spot over her neck. “I just want to bathe in it!”

“Jackie... I always hated the way I smell...”

“You shouldn't. Seriously, I love your scent, Penelope. I'm so turned on right now.”

I found myself becoming aroused again as I watched my sister pull off her shirt and caress her breasts with my moist underwear in her fingers. Seeing her do that, the first time I'd ever associated my feminine odor with sexuality, left me transfixed. I leaned up to her and kissed her tits, smelling myself on her skin. For the first time, my own scent made me feel aroused. I loved smelling myself on Jackie's flesh.

She pushed me back and slid her tits over my face, giggling as she rubbed her nipples along my lips. I sucked them as her fingers found my wet slit, tasting my essence and inhaling my own odors, shuddering as I got closer to orgasm.

Jackie kissed my lips as two fingers slid around my clit. I pulsed with desire for my sister. I wanted her to touch me all over. I pulled her over me, pressing her breasts to mine, humping up against her hand. I came hard as she nibbled on my ear and whispered to me, “you are so hot, Penelope... cum for me... cum for me...”

I pushed her onto her back and returned the affection, dipping my finger into Jackie's slit and then rubbing her wetness onto her clit. I brought my finger to my nose and inhaled. I loved her scent, that perfect, pungent mix of roses and wet pussy. She purred as she kissed me and I quickly brought her to orgasm.

We lay together, giggling as we fondled each other's boobs. She mused again about how she wished hers were bigger.

“Oh, Jackie, I love yours!” I squeezed one, then the other, buzzing with love and excitement. “They're beautiful... plus... you wiped me all over them, so they're even better now.”

My sister grinned, then asked, “so what brought that on, Penelope? I thought... I thought maybe you didn't want this anymore...”

I shrugged, “I didn't... maybe at first... but I really like it, Jackie... I like being with you... I love you...”

“I love you, Penelope, in fact,” she whispered in my ear, “I kinda like to think of you as my girlfriend... I thought maybe I'd screwed it up for us... pushing this on you...”

“No... no, I love this, Jackie. Really... you make me... happy. So happy. You make me feel so good...”

“Me, too, Sis... I love you so much... so,” Jackie said, smiling, “if I wanted you to touch me again...?”

“Only if you touch me...” I returned her smile and kissed her lips, full of love and excitement for the days to come.

- - -

How'd you do that?

“Jackie!?”

How, Penelope?

“Jackie! I thought you were lost again!” I felt my stomach rise up and my heart pounded in my chest. My sister's voice was tentative, but she was talking to me again. I wanted nothing else in that moment.

I was... gone. I left. I hate what I made you do, Penelope. I made you--

“Stop, Jackie! Just stop. No. It's not like that,” I said, calling out to my sister. I sensed her next to me, and I turned, running my hand to where her hair was falling over her shoulders. I longed to be able to see her, but running my fingers through her silky strands made me feel wonderful again. “I love you, Jackie. I wanted to be with you. Desperately. Did you see? Did you see my memory?”

Yes. How did you do that?

“I don't know, I just... concentrated on it, I tried to remember... I don't know how I let you see it, too...”

I had forgotten about that night with you.

“I came to you, Jackie. If I hadn't wanted it, I wouldn't have come to you that night. You didn't force me to do anything. Please see that. Please see how much you showed me, how much you taught me, because you loved me. I don't blame you for being curious, for... having needs. I had those, too, and I can't imagine anyone I'd have rather shared my first years with. You were my true love, Jackie. My one true love. You gave me so much... I want you to see that...”

I loved you, Penelope. Love you. I always thought what we had together was the best there was. I went away... because I felt I'd forced you to see things my way... that I made you believe it was okay.

“It was more than okay, Jackie. I don't give a shit what others might think about what we did. It was wonderful. You made me feel good about myself. I owe you so much for that.”

What about what I've done about Dexter and Kira? What about... what you've done with them, because of me? I... I agree about us... but what about them?

“Did you see, Jackie?”

See what?

“Their first time together, and the times since...”

No...

I tried to concentrate on the memories still fresh in my mind. I focused, but couldn't bring it into vivid awareness. “I... can't seem to bring you there.”

I'd love to see.

“I know,” I replied, frustrated. I tried again, but once more, could not show Jackie the moments in my bed with Dexter and Kira. “I'm sorry.”

That's okay...

“Jackie,” I paused and tried to convey how it had felt to watch my children making love, giggling as a memory came back to me, “you remember that first night I let you put your finger in my butt?”

No... I... I'm not sure...

“Remember how much you wanted to put a finger in me and I wouldn't let you break my cherry? When you suggested my butt... I wasn't sure, but the way you took your time, the way you made it so wonderful... it was like those moments, watching Kira and Dex together. The love, Jackie... the love between them... the gentleness... it was like you with me that night.”

Show me.

- - -

“I know, Penelope,” Jackie said, slowly stroking my slit after she'd brought me to a strong, wet orgasm. “I won't bust your cherry. I just... really want to finger you...”

I thought about letting her try to put her finger in my vagina anyway. I was so close to giving up on ever having a boy break my hymen. I was sixteen, Jackie a few weeks from turning eighteen, and I was so in love with my sister that I had no reason to seek anyone else, boy or girl. I was so close to giving her my cherry. If she asked again, I'd have let her.

“I have an idea,” Jackie broke into my thoughts.

“Do tell,” I replied, moaning softly, slowly building towards another release.

“Well... there's another place I can finger you... but you might think its kinda... weird.”

I was quiet a moment. “What do you mean,” I asked softly.

“A girl has... two holes,” Jackie told me, “and I have a friend who has even let her boyfriend put his dick in there.”

“Two holes,” I said, stupid and missing her point, “what?”

“Your butt.”

“My butt?”

“Yeah, silly,” Jackie said, sliding her finger down my slit and tickling the tight hole below my vulva, “your butthole.”

“Oh!” I squirmed from the first contact. “Oh! Uh... I don't know, Jackie... that is... weird.”

“I'll go slow, Penelope,” Jackie whispered, slowly spreading wetness around my tight anus. “Please... I'll be gentle...”

I wasn't sure about the idea. Even in all the times we'd touched each other intimately, she'd never so much as tickled my asshole, and I'd done my best to not notice hers when she sat on my face. There was nothing particularly sexual about my butthole, or hers. Still, I stared into Jackie's eyes and saw the desire there. If my passionate lover, my sweet love, my adoring older sister, wanted to try something, anything, I wanted to be the one she was with when she did. “Okay...”

“Lay back.” For almost half an hour, Jackie made love to me with her lips and tongue and soft touches from her fingers. My body was shivering and shuddering and trembling from her passionate attention. I felt so good. Jackie kissed every inch of my face, my chest, stomach, and legs, finally turning me over and working up and down my the backside of my body, kissing me everywhere except the one place she'd suggested. Jackie massaged my legs, my thighs, and caressed my butt.

By the time she whispered, “relax, Penelope... I'll make it feel good,” I was ready for anything she wanted to do. I'd melted completely, Jackie's fingers and mouth drawing over my body like warm butter, and when her tongue ran through the cleft between my cheeks, I didn't resist, enjoying the unusual but incredibly erotic sensation.

Jackie worked her tongue up and down my crack, teasing my anus with each pass. I twitched involuntarily, but my sister had so thoroughly aroused my senses I moaned into a pillow each time her lips kissed me in that forbidden place.

She worked saliva around my hole, and finally her finger touched me there. I suppose I'd explored myself there once or twice, but this was the first time I'd ever enjoyed the sensation. Jackie moved very slowly, carefully, sliding around my anus for long moments before she teased it open with the tip of her finger. More minutes passed as she breathed against my ass cheek, her finger very gently probing my butt. Every few moments, she checked in with me, asking quietly, “how's that feel?” I always answered that it felt wonderful.

Jackie worked up to the knuckle before I was really even aware of how far she'd penetrated me. I moaned my pleasure. “Oh... Jackie...”

“God, Penelope... I am so turned on... I'm inside you,” she said in a passionate tone. I could feel her body shuddering as she masturbated with her finger in my ass.

I slid my hand under my body and touched my clit.

Jackie's finger slid in suddenly, pushing deep into my butt. She froze and said, “sorry... sorry, didn't mean to do it so hard...”

“It's okay... oh... oh, Jackie... so good... finger my butt... please... finger it good...”

“Mmm...”

Over and over, my sister slid her index finger deep into my bowels then withdrew to the tip and slid forward, back in again. I panted and touched myself. She came, shaking in orgasm, seemingly overwhelmed by finally putting a finger inside of my body. The knowledge of that, that my part of my sister was deep in my ass, made me cum hard. I loved having Jackie in me. The odd sensation of her finger slipping in and out of my tight backdoor was more than pleasant, more than lovely. I wanted her to keep it up.

I pushed my ass back at her, whimpering, “more... please... more...” Jackie moved faster then, my butthole very slippery and taking her penetration more easily. She felt big in my butt, and the movement was a slow burn, slightly uncomfortable. I boiled into another orgasm very quickly, twirling my clit while my sister plunged her finger in and out of my anus.

I barely registered when she withdrew from me. I was half-asleep, so relaxed, feeling wonderful. I became aware that Jackie was licking my butthole, very gently cleaning my flesh. Every touch conveyed her love. It wasn't even sexual in those moments. Her tongue said she loved me, that she needed me, that she wanted to give me pleasure and make me feel good. I moaned into the pillow. I couldn't believe how much I'd enjoyed having Jackie inside me.

- - -

“It was wonderful, watching them, Jackie. They treated each other like that. Like you did with me that night.”

I'd forgotten how much you enjoyed that... and how much I loved it, too. The first time I'd been inside you, Penelope. Your ass was so tight, I didn't want to hurt you.

“You did so much more than not hurt me. You made it soft and gentle. You took your time to show how much you loved me, and when you finally fingered me, I was all yours. You could have done anything with me, Jackie. Anything.”

How could I have forgotten that pleasure?

“I think... maybe you need me to help you remember some times... maybe that's how it works.”

I'm sorry, Penelope. I've been confused. I felt... awful... that I might have made you commit incest with your children.

“No, Jackie. No. Whatever else happens, no matter how badly this might go in other families, Dex and Kira and I are closer now than ever. My children are... wonderful, just wonderful. I've shared everything with them, now, just as I did with you. These last few days... these last few days have been the best since I lost you all those years ago. I never want to lose what you helped us find. Thank you, Jackie. I love you so much.”

I'm glad. I feel right again. I needed to hear that, Penelope, I needed to know you wanted this, all this. I love you so much. I wish I could be with you fully.

“I want that too, Jackie,” I said, longing to be able to look at her again. I closed my eyes.

Penelope... she said, interrupting my attempt to retrieve her image.

“Yes?” I replied, opening my eyes.

I feel... odd... Something is... different. I can't explain what I'm feeling right now... something is... strange... like... like I'm being pulled. Not like when I go away. I see... I see someone looking at me.

“I can't see you Jackie, I can't see you,” I called out, thinking she meant me. I closed my eyes again and tried to concentrate on her face, on her freckle, her perfume. I opened them when I had the image fixed in my mind, “where are you? It's not working. I can't see you.”

I feel odd, Penelope. I see someone looking at me, she repeated, her voice edged with fear. I see three people staring. They're looking at me strangely. I... I recognize her.

“Jackie? What's going on?” My heart was beating quickly, and I stood, no longer able to feel her hair or sense her presence.

Wait... I recognize her... don't I? Don't I recognize her, Penelope? I... I...

“Her? Her who?”

I'm being... pulled... pulled, Penelope... I think I should go with them... I don't know... Penelope... help me... I need to remember this... help me remember...

“What?!” I screamed, “Jackie, what's happening?!”

Help me remember... I promise, I will remember...

- - -

Dexter and Kira, once again, kept me company for the next couple of days while I was upset and frightened for Jackie. Whatever had happened to my sister, she was gone again. I'd called, cried, screamed for her, tried to bring her vision into existence, but nothing worked. I held out hope that, like the previous time, she'd return again, but it was difficult to try to understand what had happened. The first time she'd gone away, it had been her decision. She'd left because of guilt. This time, it was something else.

I didn't know how to handle her loss again, but my week off was over and I was forced to try to appear normal at work while Dex and Kira were off to school once more.

The weeks passed and Jackie didn't return. I could describe all those days here, but it is enough to say that the sadness from losing Jackie very slowly burned away, thanks mostly to sharing love and intimacy with my children. They were wonderful, supportive, and they loved each other. Dex was a gentleman and Kira was becoming a lady. I saw in their relationship the same wonderful closeness I'd felt with my sister. I missed Jackie tremendously, but, for my own sake, and for Dexter and Kira, I had to let her go once more.

We hid it from everyone, of course. It was difficult for the two of them to be out in public and not be able to hold hands or share a kiss like they saw their friends doing with girlfriends or boyfriends. I, too, had to resist the urge to do more than appear as a caring mother when we were outside the house.

I planned a Christmas vacation for the three of us, somewhere no one knew us, somewhere we could go so that Dex and Kira could be out in public and act like the lovers they were in front of me. We looked forward to the time away from the very moment I'd made the arrangements over Thanksgiving break.

I took us to the lake, the one which had been the location for the first times Jackie and I were together. It was the only spot which made sense to me. I knew I would long for my sister, that I'd cry to remember she was gone from me again, but I also knew my children would have a wonderful, loving time together, and I'd get to share in some of that, as well, while gaining some closure on the emotional year we'd shared.

We pulled up to the same cabin my parents had rented for us over two decades before. It had aged, clearly. There was a new porch and some updated furnishings, but as I stepped inside, I inhaled the old pine and felt fourteen again. Memories of Jackie rushed into me, and for a moment I let myself pretend we were running together again, racing down to the lake. I ran, giggling, lost in the wonderful sensation of youth.

Dexter and Kira ran after me. I could hear my daughter laughing as Dexter tried to catch her. I raced ahead, rushing into the water and diving in, not caring that I was wearing slacks and a blouse. I dove under, letting the cold water rush over me. I didn't care that I shivered by the time I came up for air.

I laughed at how good I felt. It was a release I'd needed for weeks, if not years. Tears were in my eyes, and I was thinking of Jackie again. The good times ran through me and I felt her love. Kira closed the distance and wrapped her arms around me, hugging me tight, my son right behind her. “Mom?”

“I'm okay. I'm just happy... I remember this place... it has such wonderful memories for me...”

“Is this where you and Jackie were first with each other?” Kira asked.

“Yes... this was the place. That very cabin, and over there,” I pointed to the secluded area along the far side of the lake, “that's where she and I were together the second time. So many memories.”

“Sorry we lost her, Mom,” Dex said gently. “I wish she was here... for you...”

“It's okay, really,” I said, crying and smiling at once, “she brought back the good times. She brought them all back. How I could have let those be lost... I loved her so much...”

I hugged my children until we were all shivering from the cold.

We were the only people around the lake, and I took Kira's hand on one side, Dexter's on the other, leading them out of the water.

The door to our cabin opened as we walked up and I froze. A young woman stood on the porch, looking at me with her mouth open in a small oval. She was slender, small-breasts beneath a t-shirt, auburn hair down over her shoulders, bright blue eyes sparkling in the fading light, and a beautiful freckle on her nose.

I smelled roses in the air.

She looked about eighteen.

My heart leapt into my throat.

Those eyes.

I knew those eyes.

It couldn't be her.

It couldn't be.

“Jackie?!”

My tears ran freely as I ran up to her and stood a foot away.

“Who... who are you?” It was her voice, her tone, my sister's nervous habit of twirling her hair around her finger when she stood still.

“Don't you recognize me?” I pleaded with her.

She looked at me a few long seconds. Jackie stared into my eyes, and I saw the recognition dawn in her expression, “Penelope? No... no, it can't be you... You're... sixteen... no... what is happening?”

“Yes! It's me! Jackie... it's your sister!”

She shook her head and said, “I... I don't understand... I don't know how I got here... I was... coming home... to visit... and then... I walked through that door... what is happening?”

“I think I have a very long story to tell you, Jackie. A very long story.” Her eyes were beginning to water, and my tears ran freely down my cheeks.

Jackie's eyes flashed to where my son and daughter stood behind me, staring at them a moment before looking back at mine. “I don't understand... is that really you, Penelope? How can this be?”

“It's me, Jackie. You're here! Oh, you're here! Jackie... I love you so much,” I couldn't believe my sister was standing in front of me. I'd only had brief glimpses of her face the weeks before. To see her now, alive, the perfect, beautiful sister I'd lost so long ago, was overwhelming. “Oh, Jackie... I love you so much.”

She hesitated, staring into my eyes, uncertainty and fright in her gaze. “It.. it is you... Penelope...” Jackie rushed into my arms and wrapped herself around me. “I... I don't know what's going on, Penelope. I'm scared. Help me...”

“I will, Jackie. Oh, I will. You're safe, now. You're safe.” I held Jackie against me, the warmth flowing from her body into mine.

I thought of the last thing Jackie's presence said before she was pulled away from me weeks before.

Help me remember... I promise, I will remember...

“I'll help you remember, Jackie,” I poured myself into her arms. “I promise... I'll do anything for you, Sis. I love you so much. I never want to lose you again.”

She squeezed me as if she never meant to let me go. “I love you, Penelope. I've always loved you. I feel like... I've been gone away. Hold me... oh, hold me...”

Even though I was shivering, I didn't want to move. My sister was alive and in my arms. She was as she had been at eighteen, youthful and beautiful, her silky auburn hair spilling over her shoulders, her slender form pressed against me. I felt her need and her wonderful love. I didn't try to worry about whether I had finally lost my sanity. It didn't matter. I didn't know what might happen next, what difficulties we might have now that I had aged and she had come back as she was before the accident. I didn't care about any of it in that moment.

I squeezed her hard and whispered my love for her over and over, never wanting to let her go again. When I heard Jackie say quietly, “oh, Penelope, I love you so much,” I melted in her arms and pressed myself against my sister, vowing to do anything I could to be with Jackie every day for the rest of my life.

Something, some power beyond my understanding, had given me the chance to show my sister my deep love for her again, a second chance to create a life with her. I didn't care that I was now twice her age. All that mattered was that Jackie was alive, warm, and radiating her love for me as I cried tears of joy on her shoulder, stroking her auburn hair, and feeling complete for the first time since I was sixteen.

“Let's go inside,” I whispered into Jackie's ear, “we have so much to talk about...”
