Confessions of a Curious Little Sister...

Summary:

A story of a younger sister discovering herself sexually as she watches her older brother have sexual relations with his best friend.

I plan on making this into a series with her discovering more about herself and the brother going further as time goes on. If people appreciate the work, I might place more drama with the M/M relationship goes on.

My first work, any criticism appreciated. Thank you!

Chapter 1: I hate my brother.

Chapter Text

I've never really been the type to ever cross a boundary.

I do all my chores, I practice my flute every night, I'm doing well at volleyball, I'm quiet at family dinners, and the last time I got in trouble was because I fed my cat food I wasn't supposed to.

My brother, Jesse, on the other hand - he loves to mess with me. He chews with his mouth open, will blast his alternative rock music in his room without any regard to the time, and he leaves our shared bathroom a mess constantly and never puts down the toilet seat. He's pretty popular in school for what I know. He's about 6'3" as a sophomore, is the star center of our high school's basketball team, and when he's home, it's rare to see him not get constant texts on his phone.

A part of myself wishes I was more like him, I do admire his confidence and his willingness to do anything without fear of failing. I find myself a bit shy and whenever I get teased at school, I just let it happen rather than defend myself. The girls in my school aren't really picking on things that I'm self-conscious about, just usual mean girl behavior. I don't think I'm ugly - I'm athletic and I've had a couple guys confess to me that they like me, but I think it's just because I hit puberty a little bit early. Even though my brother is two years older than me, I still feel like we're decades apart.

The carpool dropped me off from volleyball practice and when I entered the house, I walked into the living room to see my brother napping on the couch in just his boxers with his homework barely attempted on the table. He's so gross, I hate it. I know it's just dad and us, but it doesn't mean they can't act like they have a girl living in the house. Feeling gross from all my sweat, I go upstairs to my room to grab a change a clothes and go to the bathroom to take a quick shower. I open the door and unsurprisingly, his clothes are all over the floor and his shaggy hair is everywhere in the sink. Since it's a Jack-and-Jill style bathroom, I locked the door that connects to his room. Disgusted with the environment, I place his clothes in the laundry basket and turn on the shower. After a relaxing hot shower, I decompress and put on a comfy t-shirt to start blowing drying my hair. I place a couple pimple patches on and put in my bangs rollers so that they're good for tomorrow. As I'm about to put on the rest of my clothes, I hear a shifting of the locked door knob from my brother's end.

"I'm almost done - just wait a bit" I call out but he didn't respond back.

As I go to put on my underwear as I'm pretty dry now, I hear the sudden opening of the bathroom door from my bedroom side.

"Haha 'sup loser" I hear my brother taunt as he jets inside with a glass of ice water in his hand.

Neither of us being able to process the situation, he tosses the water at my face as I'm shifting the underwear onto my other leg. Shocked from everything that's happening, I trip and fall onto my ass - exposing myself to him and he laughs at me. An immediate blush pulsates through my faces as I get up to assess the situation. He's crutched over and haughtily laughs at me as I push him out and lock the door.

"What the fuck is wrong with you - YOU'RE SUCH A DICK!" I scream at him as I pound on the door in frustration.

I look in the mirror and all the progress I had with my hair is now instantly gone, some of my pimple patches have fallen off, and the shirt is so wet that it's see through.

...He saw everything. I blush again as I think about what happened. He's such a jerk, why the fuck would he do that to me. What the hell did I do to deserve this.

I slowly open the bathroom door to peek my head out and see he's out of my room. I hurriedly grab ANOTHER change of clothes and this time made sure to lock my side of the bathroom door as I tried to recover all my lost progress.

After drying myself off again and hanging in my room completing some last second homework, I hear the garage slowly creak open as dad arrived.

"Hey y'all, I got us some chicken, come on down both of you!" he yelled up to us.

As we both head downstairs to the family table, Jesse makes an L with his fingers and sticks his tongue out at me. God, I hate him... We both sat at the table and you can see my dad is already pretty beat. Ever since Mom has passed, he's been working a lot more shifts at the hospital so that we can do all our hobbies. His undershirt was completely sweated through and you can see the exhaustion creep into his eyes. The grocery store fried chicken smelled fantastic and we all dug in.

"So how was your day today, dear" he said gazing at me with the most dead eyes. I do really appreciate how he tries to show his affection even after working such hard shifts....

I began to say, "It was going really solid until Jesse decided to throw a glass of ice water at -"

"OH COME ON! It was an accident, how was I supposed to know that you were in the -" he brashly interrupted.

"AN ACCIDENT? HOW DO YOU ACCIDENTALLY GO INTO MY ROOM AND -"

"WILL BOTH OF YOU SHUT THE FUCK UP" My dad bellowed as he slammed the table. He placed his heads defeatedly into his hands and under his breath continued "... I've had a really long day at work today and my boss asked me to come back in tonight after a dinner break. I'm sorry for raising my voice but I absolutely do not want to hear bickering during my one hour of break today."

"I'm sorry, dad" we both said in unison with our heads slightly low as we continued our dinner.

After some idle chit-chat about our days, Jesse asked my dad "Hey, I was wondering if it was cool if Reese came over tonight?"

"It's a Friday, that's cool with me. Promise to clean up after yourselves though, I don't want to come home to a pig-sty." Dad responded.

"Deal, thank you."

I don't mind Reese that much, he's one of Jesse's oldest friends and they're both on the basketball team together. He comes over every once in a while and he's pretty nice to me. He's a bit skinnier than my brother, but he's also pretty tall for his age with just being a tad bit shorter than my brother. He keeps to himself mostly and they typically just game together when he's over for what I've seen.

As we're cleaning up dinner, I can't stop getting the "prank" out of my head. I'm blushing as I'm putting the dishes in the dishwasher - why would he do that? Jesse saw everything, but it didn't even seem like he cared. As I look to the side of the sink, I see him collecting his homework from the living room and going up to his room. After I'm about done with my chores, he comes back down in a tank top and some basketball shorts. He flicks my forehead as walks past and grabs a soda from the fridge. I can't do anything besides blush and gawk at him, I'm so mad - I can't contain it anymore.

I'm going to get even with him.

Jesse and Reese always hang out in the basement, so I began to craft my battle station. The entertainment room has a linen closet which we keep our movies and board games in, but the door has little shingles, so I'm able to look through it without being noticed. I placed my make-up bag on one of the shelves - when they fall asleep, I'm going to turn him into the little diva he thinks he is. I placed a couple pillows on the ground to make it a bit comfortable for myself, got my phone charger, air pods to watch movies while I wait, and my water bottle so I don't need a reason to leave. I go to the bathroom for the last time, turn off all the lights in the basement, and wait for my revenge.

After about twenty minutes of waiting, Reese rings the doorbell and Jesse leads him downstairs. They sit about a foot apart on the couch as Reese turns on the gaming console. About every 10 minutes or so I check up to see what they're doing, but all they're doing is playing fighting games and swapping from boring conversations like their March Madness brackets, girls in their grade, and stupid memes they saw on Instagram. As I'm about halfway through my second movie on my phone, I get bored and start watching them more intensely. I started to notice that Reese is pretty cute, he has nice curly blonde hair, thick arms, and I catch myself admiring his shoulders a bit. I know Reese has a girlfriend on the cheer team, he's bragged about how good her head is about 8 times tonight as a ploy to make my brother mad or something. My brother is a bit more brawn than him, but Jesse has shaggy black hair and a pretty defined jawline. I can see why they're popular, despite how big of a dick my brother is.

After about another hour of waiting, I hear Jesse start to get up and I put myself in a more alert position in case he comes to the closet. He proceeds to turn off the game, goes back to Reese and says "I'm going to the bathroom and then wash up, it's getting pretty late." Jesse scuffles up Reese's hair and goes to the bathroom next to the closet I'm waiting in. I hear the shower going, but after about three minutes of Reese texting while we waits - I see him lay himself out more comfortably. After another minute, he shimmies his shorts down to his ankles and kicks them off. I turn off my phone and take my airpods out, I'm not sure what's happening but I can't help myself from staring at his boxers. He turns his phone horizontally and I start to hear some upbeat music with women moaning coming from the screen. He starts caressing his own thigh as he watches his video, slowly twirling his thumb around crotch. What the fuck is happening?

My brother opens the bathroom door and rather than shocked, I see him enter in only his boxers. "You started without me? That's pretty classless, dude." My brother scoffed.

"Yeah, yeah, yeah. Hurry up and join me already." he said while patting the empty seat next to him.

Jesse walked up to the couch and slowly removed his boxers as he went to sat. I went to cover my eyes but I stop myself, I'm not sure why I'm hesitating. I've seen him naked plenty of times, but this feels different... Reese swapped the phone to his left hand as he reached towards Jesse's cock. He gripped it like it was nothing and very tenderly beat it. Stroking it up and down at a very slow pace. As they watched the video together, I could see Reese's cock slowly emerge from the open hole in the front of his boxers. Jesse crossed his arm over and proceeded to slowly stroke his cock as well.

What the fuck is happening. I've never seen anything like this - I've only seen one porn video before and turned it off because I was confused what I watching and doing. But I don't feel confused right now, I feel paralyzed from the blush creeping throughout my entire body. My hands are sweating as I can't stop myself from rubbing my hips.

After a couple more minutes of them jerking each other off, I see Jesse slowly arise from the couch as he gets on his knees and turns towards Reese's erect cock. Jesse eagerly shuffles their boxers off as Reese begins to stand up and caress Jesse's hair. I see my brother look up into his eyes as he slowly put his juicy tip in his mouth. He places his hands around his butt as he goes slowly deeper. Both of them were big, but Reese was quite a bit thicker. Jesse begins to twist his head around and start to speed up over time.

I feel a cold sweat encroach my body and I find my left hand start to slowly grope my own breasts. God, I've never done anything like this. What is happening? Why can't I stop? Why don't I want this to stop?

I start to pant in sync with Reese's moans. I want more of this. I watch my brother's cock twitch as he tests his gag reflex with his friend's shaft. His lips are reaching the base of the cock, as if he's kissing his friend's crotch.

I find my right hand moving away from my hips and my fingers slowly start to twirl around my groin. As Jesse goes back and forth, I grope myself in unison. I've never masterbated before, I'm not sure what to do, but fuck I can't resist it anymore.

Jesse moves his right hand away from Reese's firm ass and gradually reaches up to his pecks. His thumb plays with his nipple as Reese starts to pull my brother's head in deeper.

Saliva is drastically starting to form in my mouth, but I don't want to swallow it. I run my hand past my panties and I twitch as I spread my fingers across my pussy. I split my labia and start to naturally circle around the area. Fuck. Fuck. FUCK. I'm so sensitive, it feels so fucking good. FUCK. FUCK. FUCK. I want to watch this forever. I glance at my brother's cock as it starts to throb, he's enjoying this as much as I am.

"I'm getting close, you're doing a good job..." Reese puffed and started to pull Jesse's hair from his bangs and off his cock. "I want you to cum with me... Got it?"

Jesse nods, bites his lips, and moves his hand from Reese's peck and starts to jack himself off. He seems so sensitive, every stroke has him whimper as he continues to choke on his friend's cock.

I continue to rub but every motion has me convulse in pleasure. It's so fucking much. My underwear is ruined and my shorts are soaked through. I'm so embarrassed but I couldn't care less, I want to continue. FUCK. I need to continue. I want to watch my brother service him all fucking night.

My knees buckle together as I watch Reese manhandle Jesse's back of the neck as he pulls his head into his crotch. My brother's grip around his own cock severely tightens as it throbs out white fluids all over the floor. He couldn't help himself. I can't help myself, I don't want this to end.

Suddenly, Reese's grip loosens out of nowhere as his face scrunches up and knees buckle. Fuck. Don't tell me it's done. Fuck. I'm left twitching and shaking as I watch him complete. Fuck. I wanted more. FUCK. FUCK. FUCK.

My brother backs away slightly and an opened mouth smile with his tongue out slowly creeps up, showing his friend's frothy cum swirling around. He closes his eyes and swallows it while Reese slowly pets his head. "You're getting better, someone's been a bit jealous of my girl" Reese chuckled.

"Better not forget it or you might not get more..." My brother teased with a little wink as he got up to begin cleaning up his spillage.

I take my hands out of my shorts and place them on the door as if I'm gazing through a window at an exhibit. The pillows underneath me are wet as I shift around to regain composure.

The boys put on their clothes as if nothing happened and launched a couple more games before they headed off to bed.

I stood awestruck in cold sweat for an hour as I watched them fall asleep. Once they were knocked out, I grabbed my stuff and snuck back into my room - completely forgetting about the prank.

I'm now far more obsessed with this than I will ever be getting revenge.
