Being a nosy sister – [F] watching [FM]

Being home with my family for Christmas is always tricky for me – having to put up with being in close proximity to my parents and not having any space or privacy while I’m there is always aggravating and leaves me on edge. This year has been arguably worse in that regard – my younger sister has a new boyfriend and has been going on about him incessantly when she isn’t messaging him or talking with him on the phone, bemoaning not being able to see him the entire time.

Now that the main Christmas festivities are over, today saw my parents deciding to brave the bad weather to head out and visit some friends for the day. For my part, I had no intentions of leaving the house – it was cold, wet and snowing outdoors, and I’d brought my PS4 with me for Christmas to try and amuse myself and give me a reason to lock myself away in my room. Thus, my parents going out and the poor weather gave me a perfect excuse to move my console into the living room to vegetate in front of the TV all day – a joyous occasion I was genuinely looking forward to.

My sister had other ideas however – after asking me over and over again during Boxing Day what my plans were (“I dunno” was my response for the most part), her irritation was tangible when she asked whether I was going out – or more specifically where I was going in the assumption I’d leave her alone – and I told her I’d be going nowhere all day if I could help it. Cue an argument as she sulkily told me she’d already asked her boyfriend to come over and that she wanted some privacy, blaming me for everything short of global war and famine because I wasn’t willing to go out in the snow to leave her in peace. Of course, the more she complained the more I dug my heels in, and as it became clear that neither of us were going to budge on our plans I promised her that I wouldn’t be leaving the living room or kitchen all day and that she has the rest of the house to herself. Going a little red and stammering a little as she realised that I knew what she wanted me out of the house for (as if it was somehow not clear from the very start), she argued a little longer, but it was obvious that this was a token effort as she was resigned to letting me lounge around at home. “Just don’t bother us or anything, okay?” was her closing gambit as she stomped upstairs while pulling out her phone, no doubt to tell her boyfriend to come over.

After making sure I had everything I needed with me for a comfortable day of gaming and laziness, I settled down on the couch with coffee and the agonising decision of what game I should play first, while my sister alternated between singing in the shower and stomping around as she changed and got ready. When the doorbell rang I was tempted to race to answer it to piss off my sister, but decided against it even before the grouchy, shouted “leave it!” came from upstairs before she thundered down to fling open the front door.

My sister had tried to slam the living room door shut as she passed, but – as a mistake that would repeat itself later – only pushed it half-shut, so after some murmured conversation at the doorstep (no doubt apologising for my existence) I glanced over my shoulder as they passed the room to head upstairs. I immediately caught my sister’s boyfriend’s eye as he peered in. I smiled and waved with a brief “Hey”, and he returned the greeting before my sister all but shoved him away to usher him upstairs. He was a couple of years older than my sister, and seemed tall with messy brown hair and a beard… pretty attractive, it had to be said.

That brief meeting out of the way, I settled back to my carefree gaming session, punctuated by the giggles, loud exclamations and chatter from my sister talking with her boyfriend upstairs. I thought I’d dialled this out of my head as I focused on what I was playing, but at some point I became aware that the chatter had stopped, and at the back of my mind a question kept pricking at me, enticing me. “What do you think they’re doing right now?” It was a question made more alluring by what had been a frustrating Christmas period – I hadn’t had any other “me” time, so within moments my mind was racing and my imagination running wild. I tried to ignore it, but found myself frequently pausing the game to stop and listen, straining my ears to see if I could hear anything. But there was not a sound to be heard.

My body realised what I was thinking of doing before my brain fully registered it – my heart was thumping and mouth dry as I paused the game and put down the controller again. “Just a quick peek upstairs, or listen at the door for a moment” the devil on my shoulder whispered to me, while the rest of my brain had turned into a full-blown excuse generator… “Just grabbing something from my room”, “I was coming to see if you wanted a drink” and so on. Shaking my head in disappointment at myself, I nonetheless climbed off the sofa, and with my ears keenly listening for every sound I very slowly, quietly and downright sneakily made my way to the stairs and then up them, expertly avoiding any step or floorboard that I knew would creak.

As my sister’s bedroom used to be my own, I know very well what happens if you don’t close the door fully or almost fully – it slowly, quietly swings open again, and it’s exactly that mistake my sister had made. My heart leapt up and thundered in my chest as I spied the open door from the staircase – partly because I could see in, but perhaps more so because they might see me. This wasn’t the first time I’d found myself in this position – I wrote about it two Christmas-times ago here: https://www.reddit.com/r/gonewildstories/comments/3y2o2y/driving_home_for_christmas_and_arriving_too_early/ – but since then my sister had redecorated and moved all of the furniture, so I could no longer peek in from the relative safety of the stairs and I wasn’t sure what their view out into the house might be. Now at the top of the stairs and almost frozen in fear, I was about to talk myself out of proceeding further, except at that moment my ears caught a quiet but clear rhythmic sound that was unmistakeably two people on a bed. My breath catching in my throat, I listened for a moment, and my arousal took over and padded me quietly over to the doorway.

Here, I froze once again, but I could definitely hear the bed rocking together with the occasional sigh or pant. I wanted to lean around the corner and peer into the room but didn’t dare as I didn’t know if there were in a position to spot me, but I was about to give up I remembered a large mirror my sister kept in her room. Lo and behold, there it was, and by adjusting my position outside of the room I found myself with a view of what was happening inside.

My sister and her boyfriend were both completely naked bar their socks – his black and hers white – which I remember thinking seemed quite brazen as I was home! She was straddling him, moving her hips rhythmically up and down on his cock while he massaged her buttocks with one hand. They were kissing, faces pressed together, and it looked as romantic as it did erotic as I watched via the mirror for a spell as they kissed and fucked, not knowing they had an audience.

As it was clear they wouldn’t see me, I couldn’t resist peering around the corner to watch directly rather than via the mirror. This granted me a full view of my sister’s ass as it bobbed up and down – his cock sliding easily in and out as she did so, at which point I could see both how wet his penis looked and that he wasn’t using a condom. I couldn’t tear my eyes away as I watched this scene continue for a minute or so, punctuated by sighs and kissing sounds. Then my sister shifted position, and after ducking away from the door for a second I looked back to see she’d moved her weight to bounce on him – I hear a clear, low moan from him as this commenced, with the bed’s headboard now knocking against the wall as she picked up speed and their bodies began to slap against one another. They both moaned and sighed a few times from this before my sister changed things up again to grind against him instead – I heard him whisper something but I’m not sure what, and she giggled in response.

She seemed to be enjoying this grinding motion, as she moaned louder and more frequently, picking up speed and moving more vigorously so the bed was knocking against the wall again. After a brief spell of this she returned to moving her hips up and down on his erection, and I ducked to hide with my heartrate soaring as she moved her head to one side and I caught a glimpse of the top of his head. Thankfully as I resumed watching via the mirror for a second I saw he was too preoccupied with her body slamming down on his cock and his hands kneading her buttocks, as they both breathed heavily.

Those same hands then stopped her movements, and I tensed. Maybe he did spot me? But no, he’d stopped her so that he could start thrusting his hips up against her. He fucked her rapidly, and my eyes were glued to his cock pushing in and out of her as she moaned louder than I’d heard before. This ended with a load sigh or groan from him, and I got ready to move away as I suspected he may have cum.

Again, I was wrong, as I heard their bodies moving together again, and so looked back around the door to see her bouncing on him, before switching to grinding on him again. While doing this slowly I heard them say a few things one another, although I couldn’t make out what, and then she began to speed up. Her movements became more vigorous, her breathing more ragged, and after another brief paused where they swapped some words she resumed these movements… moaning and sighing until she pressed her body down onto him with some louder moans as she seemed to have an orgasm.

As he wrapped his arms around her, I decided this was the moment to make my escape, silently and carefully making my way downstairs so that I would be neither seen nor heard. Returning to the sofa I was breathing hard and my cheeks flushed red, but I sat glued to the sofa processing what I’d just seen without even thinking to resume my game. As it turns out they weren’t finished after all, as I heard another brief round of the headboard knocking against the wall before silence, and then a resumption of chatter and giggling.

Around half an hour later my sister came into the kitchen alone, raiding the fridge for drinks and the cupboards for snacks without a word to me, while I’d returned to engrossing myself in my game without even daring to look her in the eye. With food and drinks procured she was gone again, back to her room and boyfriend.

Having fixed some lunch myself and done some more gaming, events repeated themselves in the afternoon – I paused the game several times after a period of silence, and eventually made my way quietly and carefully upstairs. This time my sister’s bedroom door was almost entirely closed, but I could still peer through the crack in the door to see her trusty mirror, which in turn let me see my sister’s boyfriend again naked but for socks, stood over the edge of the bed fucking my sister who was also naked but for socks on all fours. His body was slapping against hers and his cock moving wetly in and out while she moaned and whimpered. Holding her hips with one hand, I watched for only a couple of minutes as he fucked her until he pulled out and said something, prompting her to turn around quickly towards him. I couldn’t see whether she was sucking on him or something else to finish things off, but it was my cue to escape downstairs in silence again.

I’ve spent the rest of the day stewing in arousal, imagining being fucked like that myself – a situation not helped by me sitting in my room writing this. Part of my feels incredibly guilty for spying on my sister like this, but I guess my exhibitionist streak lives with a voyeuristic one that got a big kick out of watching her boyfriend in action like that.
