I was lying on my bed staring at the ceiling and feeling sorry for myself for the third night in a row. The girl troubles of an eighteen year old guy still in highschool were not that critical in the grand scheme of things; I fully understood that yet somehow the thought did little to cheer me up. I rolled over onto my side and tried once again to think of something else, anything else, just to take my mind of her for a little while.
Andrea had been my girlfriend for almost two years and things had been going really well I thought, particularly as I watched the constant string of breakups happening around me. Then her family decided to move away. Some bullshit about her father’s job I guess, I hadn’t really paid attention at that point of the conversation. She had been as upset as I was over the whole affair but there was precious little we could do; neither of us were independent enough to leave our families and live on our own.
“Hey Alex,” came a soft voice from the doorway.
Even with my back turned away from her I recognized my older sister’s voice immediately, she must have finally gotten home. The day Andrea actually left it hit me pretty hard and, naturally, the one person I could have talked to about it wasn’t around.
“Hi Megan,” I mumbled back.
“You want to talk?” she asked.
Mom had no doubt told her what happened as soon as she walked in the door, it would at least save me the trouble. I wasn’t really sure if I wanted to talk though, I was getting to the point where I almost enjoyed the self-pity in a weird sort of way.
“You miss her pretty bad, don’t you,” she said without really making it a question.
I nodded and felt Megan sit down on the bed behind me and reach out to ruffle my hair the way she did sometimes.
“It’s stupid, I know,” I said. “Just a highschool crush, we probably wouldn’t have lasted anyway. Even people who get married don’t last very long.”
“But now you’ll never know,” Megan said with that note of understanding in her voice that I loved to hear.
My parents loved me and they did their best to empathize with me but they were a different generation and they just didn’t understand. Megan was different; she didn’t always have advice for me but she listened and, more importantly, she never judged. That was the main thing that set her apart from my parents and even my friends, I could tell her the most embarrassing and terrible things I’d done or thought and she wouldn’t so much as flinch.
“Yeah, that’s part of it I guess,” I said.
I returned to my previous position on my back and looked up at my sister. She was sitting with her knees pulled up to her chest and looking at me with a completely neutral expression.
“It’s not really a big deal though is it,” I continued. “People are starving and dying all over the place and I’m whining about a girl. Suck it up, right?”
“Alex,” she said slowly, “just because yours isn’t the worst problem in the world doesn’t mean you’re not allowed to care about it. It’s okay to be sad that Andrea’s gone, even I’m going to miss her.”
I felt tears welling up and blinked them away quickly. Megan wouldn’t care but I hated to cry even when I was alone, it made me feel pathetic. Or maybe it was just because I only cried when I was already feeling pathetic, hard to say.
“I dreamt about her,” I said quietly. “The past two nights I wake up and she’s in the room with me, it seems so real. She doesn’t talk or anything even when I talk to her. Then I try to touch her and I realize she was never there.” I snorted, “more of a hallucination than a dream I guess, since I’m awake and all.”
Megan nodded thoughtfully and I noticed she was chewing on a few strands of her hair in the corner of her mouth. Usually that was sign she was focused on something and not paying attention to what she was doing.
“Sometimes that happens to me,” she said. “When I’m stressed or worried sometimes I get hallucinations like that. One time I woke up and was convinced there was a massive hole in the floor. I had to go to the bathroom but I was terrified I would fall if I got out of bed. I think I ended up actually jumping off the end of the bed where I thought it was safe. Funny what you remember sometimes isn’t it?” she finished, smiling at the bizarre memory.
“Yeah,” I agreed, forcing a weak smile of my own.
“Anyway, think you’ll be okay?” she asked.
“I think so, probably just going to sulk for a while then I’ll be fine,” I told her.
“Alright, well I’ll be around if you need me,” she said as she got up to leave.
“Thanks Megan,” I said before she made it out the doorway.
“Anytime little brother,” she called back.
Just like the previous two nights I woke up disoriented in my darkened room. Andrea was standing beside the bed watching me and I smiled happily at her.
“You’re back,” I whispered.
“Just checking on you,” she whispered back. “You were making noises like… I don’t know, bad dream maybe?”
She ruffled my hair fondly the same way Megan always did and I enjoyed the feeling for a moment before realizing what was different.
“You talked,” I accused her.
“Yeah, so?” she asked with a raised eyebrow.
“You never talked last time Andrea, how come you can this time?”
She paused for a long moment, long enough for it to dawn on me that she had touched me too. When I had tried to touch her the previous two nights she had simply vanished like a ghost. Pushing my luck I reached out and gently felt her arm. It seemed solid and, better yet, she stayed exactly where she was.
“Maybe your imagination’s just getting better,” she said softly.
“Maybe,” I agreed. “Can you stay with me a while?”
“Sure Alex, just for a little while.”
She lay down next to me on the bed facing me as I shifted to give her enough room.
“I’m glad you’re here,” I told her. “I miss you so much already.”
I leaned in to kiss her and felt her hesitate for a second before pulling away. I frowned in confusion and backed off.
“What’s wrong?” I asked.
“Nothing, just… it’s nothing,” she said.
I tried again and this time she didn’t back away when I kissed her, although she didn’t seem to be responding much either. Then again, I reminded myself, she was just a figment of my imagination. I stroked her bare arm up and down and felt her slowly relax under my hand. When she seemed calm enough I reached for her breast and gently cupped it in my palm.
“Alex!” she protested as she grabbed my wrist.
“Shhh,” I hushed her.
Even with her loose grip around my wrist I began fondling her breast delicately before pinching her nipple a little roughly the way she liked it. I heard her gasp and smiled to myself before pulling my hand free of her fingers and sliding it down across her tummy. Her legs were bare which I found odd since I could have sworn she had been wearing pants when she climbed into bed with me but I didn’t dwell on it long. It was just another inconsistent detail to remind me that it wasn’t really Andrea in my bed, just a facsimile created by my mind.
She was tensing up again as I caressed her thigh and slowly worked my hand under her shirt. Still I was unprepared for her reaction when my fingers reached her panties.
“No!,” she yelled sharply.
I jerked away instantly as though I had been burned. She may have seemed reluctant before, but that was a flat out order to stop.
“I’m sorry, I didn’t… I’m sorry,” I apologized.
Her face softened as she saw how upset I was getting and she pulled my head to her shoulder.
“Hey, it’s okay, I’m not mad. Just go to sleep Alex, just go to sleep,” she repeated soothingly.
She rocked me gently in her arms for a while and I felt myself gradually calm down before finally drifting back to sleep.
“Man that was a weird night,” I told Megan the next morning.
“Why’s that?” she asked.
“Just the dreams. Hallucinations. Whatever.”
We were eating breakfast and I was taking advantage of the time before our parents showed up to talk to my sister before I had to go to school. I was worried my memory of the previous night would bug me all day and was hoping Megan might say something that would help.
“Andrea showed up again,” I continued. “It was different thought, more real. Like she was actually there almost. She… she didn’t want me to touch her though, I don’t know what that means.”
“Could be nothing,” Megan suggested. “Could just be your brain could only handle so much.”
“I don’t think so,” I said, shaking my head. “I remember she held me after that, like it wasn’t the contact that was bad just the, y’know, sexual stuff.”
I felt my cheeks get slightly warmer even though Megan didn’t so much as blink. It wasn’t the mention of sex that embarrassed me, we had talked about that stuff many times before, but when I said it out loud I realized how dumb it sounded that I had tried to fuck the product of my own imagination. Still, I guess if I had been thinking clearly at the time it wouldn’t have been much of a hallucination.
“Maybe it’s just my subconscious trying to tell me something,” I sighed. “Like I wasn’t good enough for her.” I smiled wryly, “I probably wasn’t, you know.”
“Don’t say that Alex, don’t ever.”
I was taken aback by how firmly my sister said those words, like the idea that I didn’t deserve Andrea bothered her more than me.
“Well, whatever. There must be a reason for it though,” I persisted.
“Maybe,” Megan said thoughtfully. “Just try not to dwell on it too much, alright?”
“Alright, I’ll try,” I agreed even as I doubted my ability to follow through.
I had a hard time getting to sleep that night, I spent what seemed like hours tossing and turning in my bed. The thought that maybe I really hadn’t deserved Andrea while I’d had her surfaced occasionally but really I was more worried about her showing up again in the middle of the night. The memory of how she had reacted when I had tried to touch her really bothered me.
I felt myself being shaken and stared around in confusion. I didn’t remember sleeping but the clock on my dresser said it was almost three in the morning so I guessed I must have. Andrea was once again beside my bed, this time with her hand on my shoulder looking concerned.
“You seemed like you were having a bad dream again,” she whispered.
“I don’t remember having any dreams,” I shrugged dismissively. “But anyway, can you tell me something though while you’re here? Last night, did I do something wrong?”
“No, nothing wrong. I’m sorry about last night, that was my fault,” she said, smiling faintly at me.
She climbed into bed with me and this time I made sure she had plenty of space and made no move to touch her.
“Alex, I love you, you know that right?” she asked.
“Yeah Andrea, I know. I love you too.”
She flinched a little as I said her name. That seemed weird to me, if anything I would have expected her to flinch when I said I loved her.
“This might be the last time I’ll be here,” she told me. “I want you to understand how much I care for you so… we can do anything tonight Alex, anything you want. I won’t stop you.”
“Are you sure? We don’t have to if you don’t want to,” I replied.
“I’m sure, anything you want just for tonight.”
I tentatively reached out and brushed her cheek, it felt as real as last night and this time she didn’t back away or tense up at all. When I kissed her lips they parted for me giving me as much access as I wanted. I let my hand fall to her breast and caressed it lightly over her shirt feeling the nipple harden under my touch.
All the things Andrea used to like when we had sex were flashing through my mind and I was determined to make her happy, especially since she said this might be the last time I saw her. I gently kissed her earlobe, barely brushing it with my lips, before nibbling on it as delicately as I could. She moaned quietly as I traced my lips down the side of her neck to the collar of her shirt; that would have to go.
“Sit up a little,” I whispered as I found the bottom of her shirt.
With her help I pulled the shirt up over her head and dropped it on the floor. Her breasts were as amazing as I remember, even in my darkened room. If anything I would almost have said they looked better.
“Mmm, you like them Alex?” she asked.
I nodded affirmatively with my mouth already locked on the underside of her left breast where I knew it was most sensitive. She was still completely passive, letting me do all the work, but at least she seemed responsive to my efforts; every now and then she would let out a low moan and squirm a little on the bed.
Eventually I slid down toward the bottom of the bed, stopping briefly to nuzzle her tummy as she lay on her back watching me. Her panties were damp and I breathed in deeply, enjoying her smell immensely as I had so many times before.
“This okay?” I asked with my hands in the waist of her panties.
Again there was that slight hesitation before her answer.
“Mm-hm, anything you want tonight li- Alex,” she whispered.
I caught the stutter in her voice but ignored it, the one piece of clothing remaining on her body occupied my entire conscious mind. Slowly, so slowly, I pulled her panties down her legs and over her feet. She lay before me then fully naked and so beautiful to me I could do nothing but stare for a long moment.
“What you going to do now?” she whispered nervously.
Her words jolted me into action and I spread her legs farther apart before leaning in close. She was trembling beneath me and I stopped momentarily to look up at her.
“Are you scared Andrea? Nothing to be nervous about,” I promised.
“I know, I’m just… waiting.”
I shrugged to myself and leaned back to her waiting pussy. Stroking her pussy lips up and down with my fingers I gradually parted them to reveal her firm clit that seemed to be begging for attention. I gave it a quick lick and felt a surge of satisfaction as I heard the small whimper from the head of the bed.
My tongue danced across her clit, giving her the short, fast touches she liked as I slowly pushed one finger inside her pussy. Her pussy muscles clamped down when my finger was only halfway inside and I stopped for a moment until she relaxed. When I felt her pussy loosen up sufficiently I inserted a second finger and started pumping them in and out without letting up on her clit.
Soon her breathing was becoming noticeably more ragged and her hips were wriggling beneath me. I closed my lips around her clit and licked just the tip in long, smooth movements. I thrust my fingers as rapidly as I dared and kept my tongue in position as much as possible while she came, then sat back grinning.
“Mmm, that was nice Alex,” she breathed.
My smile spread wider and I crawled up to kiss her again, letting her taste her pussy juice on my chin. I was so horny at that point and my cock was straining uncomfortably against my shorts. I reluctantly pulled away from my lover long enough to strip them off then climbed back on top of her.
The nervousness had returned to her face but there was also lust evident in her eyes as my cock brushed against her wet pussy. I let my erection slide up and down the entrance to her warm cunt until I felt her hips rocking against me, then gently pushed inside her. She immediately stopped moving and closed her eyes as I worked my way deeper.
“You miss that?” I whispered into her ear.
She didn’t say anything but simply nodded slowly in response. I began thrusting my cock in a slow, gentle rhythm inside her pussy letting her get used to my presence. I ran my hand over her breasts as we fucked, alternating simple caresses and swirling my fingertips across her nipples. When her hips began rising and falling to meet my movements I increased my pace, thrusting inside her faster but still not too hard.
“Oh god Alex, keep doing that,” she moaned.
I was close to cumming at that point but held on as best I could while maintaining my pace. The fingers of her left hand sank into my upper arm as she buried her face in my shoulder while her pussy convulsed around my cock. I couldn’t hold myself back any longer as I felt her orgasm hit but fortunately I didn’t need to. My cum sprayed deep inside her still spasming pussy just as her orgasm was beginning to fade.
My arms strained to support me any longer as the last of my semen emptied itself from my softening cock and I barely managed to roll off of her before collapsing. I lay there for a few minutes listening to the sounds of our breathing returning to normal before turning to her.
“Fell better now?” she inquired.
“Yeah,” I said. “I really do.”
A few weeks went by after that night and I was definitely feeling like I was over the worst of it. I still missed Andrea sometimes but it certainly wasn’t as constant or as painful anymore. I knew the last encounter with her had been a dream, it was pretty obvious afterward even if it had felt so real at the time, but somehow I think it helped anyway.
I found myself spending a lot more time with Megan at least partly because she was, once again, the only girl in my life. She didn’t seem to mind me following her around like a lost puppy either, just another testament to how much patience she always had for me.
We were sitting around in her room talking about nothing in particular, me on the bed and Megan at her computer, when I noticed the box on her dresser. I had seen it there earlier and hadn’t paid it any attention, but when I took the time to read the writing on the side I realized what it was and froze.
“What?” asked Megan, turning away from the game of solitaire she had been idly playing when I stopped mid-sentence.
Following my gaze she saw what I was looking at and a look of resignation passed over her face. On her dresser was the box for a pregnancy test kit, and it was open.
“I’m sorry,” I said and felt myself blushing. “That’s none of my business.”
“No, it was stupid of me leaving that lying around. I just didn’t think… well I didn’t think, let’s leave it at that.”
Megan got up and tossed the box in her garbage can before sitting back down. I wondered if I should leave, the situation was pretty awkward and I didn’t know what to do short of hoping it would blow over given time.
“I’m not pregnant,” she blurted out finally.
“I just got nervous,” Megan continued. “There was a guy about a month ago and….” She shrugged helplessly and visibly tried to gauge my reaction. “You’re not going to tell mom or dad, right?”
“Come on Megan, you know I wouldn’t do that. I am kind of glad you’re not pregnant though,” I admitted. “I don’t think I’m ready to be an uncle.”
“And I’m not ready to be a mom,” she replied, seeming a little more relaxed. “Hopefully I won’t be as dumb in the future.”
It bugged me a little that Megan had even considered that I might tell on her, but I consoled myself with the thought that she was probably just nervous about the whole ordeal. She had been hiding it pretty well up until then, I hadn’t even noticed anything different.
It wasn’t until that night while I was lying in bed that a disturbing thought crossed my mind. I pushed away immediately the first time but it kept returning, just gnawing at the back of my mind.
It was almost a month since the last time Andrea, imaginary Andrea rather, had shown up which would put it about the same time Megan said she might have gotten pregnant. Just coincidence I assured myself, that’s all it could be. And yet when I recalled how real Andrea had seemed at the time, how real the sex had been, I couldn’t help but think there might be more to it.
Eventually I got tired of the speculation, what my mind was suggesting was not something I should ever think about. Just the thought that I had somehow mistaken my sister for my ex-girlfriend and….
No, it was simple; all I had to do was go ask Megan who the guy was and put the matter to rest. I didn’t like prying into her life like that but I was prepared to do it anyway given the circumstances.
“Megan,” I called softly as I reached her room.
“Hmm? What is it?”
I must have caught her before she fell asleep since she answered almost immediately. She sat up in her bed and stifled a yawn as I stepped closer to her.
“I need to know something and it might seem a little weird,” I explained. “Who was the guy you were talking about? The one from a month ago.”
She didn’t answer right away so I asked again.
“Megan, who was he?”
A hint of desperation was creeping into my voice that I couldn’t fully control. Megan continued to stare at me and I realized that I hadn’t been imagining things.
“Alex, I don’t remember alright,” she said finally.
“Yes you do,” I replied numbly.
I felt sick at the thought of what I had done. All the times my sister had been there for me, everything she had done for me, and I had….
“I’m sorry Megan, oh god I’m sorry.”
I stumbled away from her into the hallway trying to make it back to my room. I had fucked my sister, that was clear to me now. Looking back it seemed so clear, so many things that should have given it away that I hadn’t wanted to see.
I collapsed on the floor beside my bed not having the strength to do anything more than curl up in a ball. She didn’t deserve what I had done to her, I could never apologize enough.
“Alex,” Megan called softly.
She had followed me to my room, I couldn’t understand why she would do that knowing how sick I was. Except… except my sister would never hate me even after what I had done. The thought upset me even more and I tried to curl up further and somehow disappear into myself. No, I didn’t deserve to ever see her again, I would have to leave; that was all I could do for her now.
“Alex please look at me.”
The sound of her voice cracking midway through her plea almost made me look out of pure reflex. My sister was upset and I instinctively wanted to help, but of course I couldn’t. Not this time.
“I’m so sorry Megan,” I whispered. “So, so sorry.”
She knelt beside me and suddenly her hand was on my head, gently stroking my hair.
“It’s not your fault little brother, it was me. You didn’t even know what you were doing.”
“I should have though, I should have realized.”
My eyelids were starting to hurt where I was squeezing them shut so tightly and my arms were beginning to tremble.
“Is it really so disgusting to you, Alex? Does the thought of us together bother you that much?”
The hurt in her voice broke my resolve and I opened my eyes finally. The tears running down her cheeks were the first things I noticed and I moved my hand to wipe them off before realizing what I was doing and jerked back.
“I didn’t mean to hurt you,” I mumbled.
“You didn’t, you never have. I let you do what you wanted, remember? I knew what was happening and it was my decision.”
Megan shifted slightly to lean back against the bed and settled in more comfortably.
“Because you were hurting little brother, and I knew I could make it better. It could be my secret and you would never have to know.” She smiled a little sadly at me. “It would have worked too, if I’d really wanted it to be a secret.”
“I don’t understand,” I said in genuine confusion.
She looked away for a moment, long enough that I was getting ready to verbally prod her again.
“I was selfish Alex,” she said softly. “I got careless and I know it’s because deep down I wanted you to know what I… what we did. I hoped maybe someday you would feel the same about me that I feel about you.”
She stood up as I stared at her in shock, unable to fully process what she was telling me.
“I know it was a stupid thing to do, stupid and selfish,” she said. “But it’s done now and… really I just hope you won’t hate me for it.”
She flashed me another one of those sad smiles and stepped out the doorway. She paused in the hallway and looked like she was going to say something else but stopped herself and walked away.
Things were naturally kind of awkward between Megan and me the next few days. She did her best to make things easy on me, she didn’t try to pressure me into talking and generally gave me my space. I could tell she was hurting though, it was obvious every time we passed each other in the hallway or had to pretend like nothing was different as we sat around the dinner table. Obvious to me anyway, our parents didn’t seem to notice anything different but that could just be because I was looking for it and they weren’t.
I missed her too, as weird as that sounds. We still lived in the same house and saw each other every day yet I still missed her. Sometimes I would feel like going to talk to her and would start heading to her room before remembering that it wasn’t that simple anymore. For the first time in a long while there were issues between us that needed resolved before we could just sit down and talk like we used to.
Of course I wasn’t even sure we could go back to the way things were, Megan had as much as said that I was more than a brother to her but I didn’t know if I could feel the same about her. Sure I loved her but she was still my sister and there were lines we just weren’t supposed to cross; except of course that we had already crossed pretty much the biggest line there was.
If only she wasn’t my sister, or if society had evolved differently somehow, then we could have done whatever we wanted. That was the real question I had to answer, all else being equal what would I want my relationship with Megan to be? When I thought about it like that it seemed simpler; I wanted her to be happy and if that meant we would be closer than before, closer than we should be, then that was okay.
The first time I decided that I was okay with the idea of having sex with my sister I angrily threw the thought from my head and did my best not to think about it again. Gradually I realized that it wasn’t just a sick fantasy, I actually was okay with it. If I’d had more time to think about it before confronting Megan I might not have gotten upset at all.
The problem was that I still had to deal with the real world and that meant that my relationship with my sister could never be that way; too many people could get hurt.
“Hey Alex, you in there?” came Megan’s voice through my door, startling me from my daydreaming.
“Uh, yeah,” I called back.
“The pizza just got here, I’m just going to leave it in the kitchen whenever you’re ready,” she told me.
Our parents were gone for the evening so Megan had ordered pizza for us. I sighed as I realized that once again she was thinking of me and not forcing me to so much as be in the same room as her just long enough to grab some food. She was so good to me, always had been, and I was being a horrible brother. So what if people could get hurt? Megan was already hurting, and so was I for that matter.
Reaching a decision I made my way downstairs and put a couple slices of pizza on a plate before heading to the living room. Megan looked up at me in surprise as I sat down on the far end of the couch.
“Hey,” I said simply.
“Hey,” she said back, giving me a small but real smile; the first one in what seemed like a very long time.
We didn’t say anything else for a while but I think my presence was enough for Megan. I stole glances at her every now and then and she definitely seemed happier than she had the past few days.
I got up eventually to take my plate back to the kitchen and when I returned to the living room I took the opportunity to sit down right next to Megan. She immediately leaned against me and I wrapped my arm around her pulling her tight to me.
“I’m sorry about the last few days Megan,” I whispered.
She shook her head, “no, I understand.”
“That doesn’t make it okay. You’re always there for me when I need you, but I… I reacted badly and I’m really sorry.”
Megan snuggled up closer to me until I could feel her hair tickling my neck. I took that as I sign of her accepting my apology even if she didn’t think I needed to.
“It doesn’t have to be different you know,” she said. “I mean, I can’t do anything about what already happened but we don’t have to ever do that again, not if you don’t want to. I’m just glad that you don’t hate me for it.”
“Honestly Megan I don’t know what to think about it. All I really decided was that I want you to be happy, you deserve it.”
She gave me a cryptic look for a second then slowly brought her face closer to mine. She kissed me gently, then pulled away to gauge my reaction. Before she could say anything I leaned forward and kissed her more firmly, pulling her onto my lap in the process.
“That didn’t take long,” Megan said when we broke off again.
“Can’t help it, you feel too good.”
The feeling of holding my sister so close, her face mere inches from mine, cut through the all the problems I still had not resolved. I wanted to be with her, and if that meant an unconventional relationship then at least we could deal with the consequences together.
I let Megan push me onto my back across the seat of the couch as she manoeuvred herself to straddle my waist. Her hands ran over my chest and then moved downward to slide under my shirt. I pulled her head closer for another kiss and let her hair fall down around us, trapping us in our own little world.
It was only when I felt her try to pull my shirt over my head that I finally grabbed her wrists to stop her.
“Shouldn’t do it here,” I said.
Our parents weren’t supposed to be back for a while but there was no point taking stupid risks. I saw Megan frown as she had the same thought that I did, then she shrugged and stood up.
“Alright, come on.”
She gave me a hand off the couch then practically dragged me up the stairs to her room where she pushed me playfully onto her bed. Before I could say anything she had pulled off her top and dropped it to the floor. She then resumed her attempt to remove my shirt as I stared at her bra-covered breasts.
“You can touch them if you want,” she said, finally tugging my shirt over my head.
I let my hands roam over my sister’s breasts, paying particular attention to the edges that weren’t fully covered by her bra and revelling in the feeling of her bare skin. I fumbled with the clasp briefly but actually managed to unhook her bra fairly quickly and let it fall away from her chest.
“You like them?” she asked.
I nodded dumbly and stared at her perfect breasts with their tiny pink nipples poking out at me. Megan let me stare for a minute, then turned sideways to give me a different angle as well as allow her to work on removing my pants. Feeling her fingers around my crotch sent shivers up my spine even before she began tugging my pants down my legs.
Finally I lay naked on my sister’s bed, my fully hard cock pointed up at the ceiling with her eyes fixed unashamedly upon it. Her hand reached out but she quickly caught herself.
“Can I?” she whispered.
“I don’t think I could say no at this point.”
She stroked my cock a few times, letting her fingers run delicately up and down before inexplicably starting to giggle.
“What?” I demanded.
“Nothing. Just, my brother’s dick in my hand you know? We’re being kinda bad.”
“Yeah,” I conceded. “That is kinda bad.”
“We could be worse though,” Megan purred.
She stood up and began swaying back and forth rhythmically as she unbuttoned her pants and slid them down to the floor. I sucked in a long breath as my sister stood before me in nothing but a pair of panties, slowly twirling to let me see her from every angle. It suddenly dawned on me that it was really going to happen, we were going to have sex again.
“Megan, I don’t have any condoms with me….”
She stopped moving and gave me a wide smile.
“I’m on the pill now, ever since that night. Well, a few days after anyway.” Her smile turned seductive, almost predatory, as she continued. “That means you can have me anytime you want little brother. Don’t have to worry about that.”
With no further teasing she shed her panties and climbed back on the bed, once again straddling my waist. Her pussy was mere centimetres from my waiting erection and I had to force myself to lie still and not pull her down on top of me.
“You ready Alex? Ready for you big sister?”
I didn’t trust myself to speak and instead just nodded affirmatively. Megan lowered herself painfully slowly and I groaned in pleasure as her warm pussy gradually engulfed my cock. I had been inside her once already but actually knowing it was my sister this time made the experience so much more intense.
Finally she bottomed out on me and was still for a moment, practically sitting on my lap. Then she began rocking back and forth on me, letting my cock slip a few inches out before sliding back in. The position was a new experience for me but certainly not an unpleasant one.
Her breasts were awkward to reach from my position so I settled for running my hands freely over her naked legs and ass. Megan cooed happily when I let my exploring hand brush her clit so I left it there and did my best to rub it smoothly even though her movements made that difficult.
“M’gonna cum soon,” I warned her.
I could feel my orgasm approaching though it hadn’t quite reached the urgent stage yet.
“Okay baby, but just give me a minute first,” she panted. “You can do that for your big sister can’t you?”
I didn’t know for sure that I could hold out that long but I was going to do my best. Feeling a burst of inspiration I thumbed my sister’s clit roughly as she rode me harder and almost instantly her mouth opened in an expression of pleasure.
“Oh my god, oh fuck,” she nearly yelled, making me glad our parents were still out.
The arrival of my sister’s orgasm preceded my own by mere seconds, though the full impact of the fortunate timing was lost on me at the time. Megan continued riding me until both our orgasms subsided then slid off me onto to the bed.
“Wow,” I said, unable to come up with anything more eloquent than that.
“Yeah,” she agreed.
“So what now?” I asked after a moment.
“Well, we still have about an hour and a half until mom and dad get back,” Megan said thoughtfully. “So until then I guess we could do… anything we want.”
Anything we want, I liked the sound of that.
