My Sister, The Horny Disaster

I’m stuck with my sister for the summer, and there’s one big problem; she won’t stop masturbating!

Hey gamers! Thought I’d try my hand at some incest stuff, and this is what I came up with. As you could probably guess, this is a work of fiction. Enjoy! (And I guess jerk off to it if you’re into that sort of thing.)

—

My name is Alex, and I’m a 14 year old boy.

This summer, my grandparents decided they wanted to see me more often. My parents agreed to let me head up north to stay with them for the season, since it was true that I hadn’t seen them in a while. However, there was one small issue; they didn’t have any extra space. They didn’t have a guest room, and they felt it would be wrong to make me sleep on a couch.

As a solution to the problem, my 23 year old sister, Samantha (who I usually call Sam), agreed to let me stay with her, since she was nearby. I packed my things, including plenty of clothes, and stuff to pass the time while I didn’t have anything to do. My parents drove me up the coast, and dropped me off at Sam’s house. I should’ve figured out that something was off that very day; it was a small, messy house. Outside, the mowing work on the grass was shoddy, and the road was cracked to hell and back.

The inside of the house was a completely different story. The house had only 5 rooms; a living room connected to a kitchen, 2 bedrooms, a bathroom, and the garage. Nearly all of them were complete messes, save for the extra bedroom. For my sake, she had made sure that it was clean. Over the summer, my grandparents would come to pick me up every once in a while so we could go somewhere and do something for the day—maybe the park, maybe a nice restaurant, or just hanging out at their house. In the downtime, at my sister’s house, it was a completely different story.

On the first day I was there, we didn’t do much; we just watched TV. When it was bedtime, I took a shower, brushed my teeth, and headed to bed. I got dressed in my pajamas, and got in bed. I didn’t go to sleep immediately, though. I pulled out my phone, and scrolled through Twitter for a bit. Since the house was small, I could still hear my sister in the shower. Notably, she took longer than me. A lot longer than me. About 40 minutes. Eventually, the shower turned off, and I heard her go to bed. Eventually, I got bored of looking at my phone, and started to lay down.

After a few minutes, I started hearing something weird through the wall. It sounded like a weird, wet slapping noise. Soon after, I heard Sam’s voice. It sounded almost like… moaning. Then, I realized; my sister was masturbating! I tried to ignore it and go to sleep, but she was going at it aggressively. The wet noises got louder, and she moaned harder. Eventually, she groaned the loudest I’d heard yet, and after a few more slapping noises, I didn’t hear anything else.

The next morning, I didn’t mention it. It was hard not to remember it, though, since she had a noticeable wet spot in the loose shorts she had been wearing. I didn’t point it out, since that would be an awkward conversation. Later that morning, I left with my grandparents and we went to the mall. During the next week after that, things were just about the same; I would be with my grandparents for a majority of the time, and whenever I was home, me and Sam would hang out for a bit. And every night, she would retreat to her room for a session of self-pleasure. I didn’t hear the same noises every night, but it was clearly in an attempt to reach the same goal.

Unfortunately, I couldn’t indulge myself in the same way; it just felt awkward to do it while my sister did the same next door. By the time she would finish, I was too tired to even bother. Over the second week, she got more bold, doing it even during the day. I could tell she was trying to be quieter, but it wasn’t working. Sometimes, I would be watching TV in the living room, and she’d come and watch with me right after she’d just been fucking herself.

The other night was when I decided I had enough, and I was gonna have to talk to her about it. We had been watching some dumb TV show that she wanted to watch; it wasn’t unbearable, so I didn’t complain. I don’t know what was going on, but a passionate love scene began on the TV. I heard my sister lightly moan. To my surprise, she was touching herself on the other side of the couch; she was covered by a blanket, but her movements were obvious. Soon after, I lied and said I was tired, and went to bed.

About an hour later, I was thirsty. I decided to go get a glass of water. I heard Sam moaning again, but assumed she would be in her room. I walked out to the kitchen, and to my horror, she was on the living room couch fully naked with her hand between her thighs, watching porn on the TV. She continued as I walked towards the cabinet, oblivious to my presence. I tried not to make myself obvious. I made a bit of noise getting water, though, and she looked at me. She covered herself with a blanket and turned off the TV, but I could tell she was still going at it, just trying to be quieter. I got my water, and headed back to my room. Only a minute later, I heard noise coming from the living room again. Since I’d been putting up with it so much, it wasn’t too hard to fall asleep.

The next day was just about the same as usual; my grandparents came and picked me up after I had a simple breakfast of cereal, and headed down to the local pier to see the sights, visit the temporary summer carnival, and have some food. They brought back to Sam’s house at the end of the day, and we hung out for a bit. This night, though, Sam went to her room about an hour earlier than usual. Since we were going through the show together, I figured I would also head to bed, though I wasn’t planning on sleeping just yet. As is typical, Sam began her nightly ritual. I heard her rub herself silly, a sound like mixing creamy mac and cheese.

An hour passes, and she hasn’t stopped—not for long, anyway. I begin to get bored of looking at my phone, and decide to go look for a snack. I head out to the kitchen, and dig through the cabinets. Once again, I hear Sam reach climax, and start panting. This time, though, I hear her get up. Her door opens, and she comes out of the small hall that leads to our rooms. She’s wearing a loose-fitting white shirt without a bra, so I can clearly see her nipples. The only thing covering her crotch is a pair of beige panties that I can tell she just put on, seeing as they are almost entirely dry and her thighs are drenched with her orgasmic fluids. She opens the fridge, and reaches into the almost empty drawer, pulling out a cucumber. She begins to walk away, but I speak up.

“Hey, Sam,” I say. She turns around.

“What’s up?” she says, as if these were perfectly normal circumstances.

“Can you… uh, try to be a little quieter?” I say. She looks panicked.

“O-oh my God, you could hear me?” she says, a bit freaked out.

“Uh, yeah,” I say, nervously. She sits down at the table, and sighs.

“Alex, I’m… so sorry,” she says, sadly. “My boyfriend left me only a few days before you came up, and I’ve been a serious mess.” She hangs her head down. “I must’ve been making you feel so uncomfortable for the past two weeks.” She stands up, and begins to walk towards her room, putting the cucumber back in the fridge. As she sees me again, she looks down.

“Do… do you have a boner right now?” she says, a humorous tone taking over her somber voice. At first I think to deny it, but then I look down. Sure enough, I’m pitching a tent in my pajama pants. I cross my legs slightly.

“Oh my God, you do!” she says. “Are you some kind of perv?” I can tell she’s joking, but I’m still annoyed.

“I can’t do anything about it while you’re moaning next to me!” I say. Still, she eyes my erection.

“Do you want me to help you do something about it?” she says, in a lower voice.

“W-what?!” I say, surprised.

“You’re clearly a big boy, and I think you deserve something more than your hand,” she says, seductively.

“W-wait, but you’re my sister!” I respond, panicky. Suddenly, she lifts her shirt, to reveal her breasts. She moves back and forth, shaking her big, pale boobs in front of my eyes.

“You wanna touch your sister’s boobs?” she asks. I don’t respond. Though my brain tells me not do it, I reach forward. I grab her boob gently, and I squeeze it. I gently knead her soft, doughy tit with my hand; it’s the first one I’ve ever touched. She puts her shirt back down, and I pull back my hand.

“Didn’t you just say I was a perv?” I ask, confused.

“Sure, but you also have your big, warm dick down there, and I’m sure you can’t bear not being able to shove it in something,” she says. “Do you wanna fuck your big sis, or not?” Her bluntness takes me aback. Even though it feels wrong, I’m turned on; my cock is throbbing.

“S-sure,” I say, nervously.

“Then come and take your prize,” she says, walking me to her room. As I follow her, she lifts up the back side of her shirt, flaunting her ass. She opens the door to her room, and I look in. It’s a disaster; her blankets are a mess, as is her floor. There’s a visible wet spot in the middle of her bed. She shuts the door behind me.

“You ready to see a real girl’s body for the first time?” she says. I don’t respond, but she undresses anyway. She tosses off her white shirt. She turns around, and begins pulling off her panties. She pulls them down her legs, making extra sure to bend down and stick her ass out towards me. I can clearly see her creamy pussy. Then, she turns around.

“How do I look?” she asks. I look her up and down. She’s only a few inches taller than me, but she’s clearly older than me. I look at her large breasts, and then down at her wide hips. She can tell I’m interested in her lower body, so she turns around. Her butt is round and well-defined. She turns back around.

“You, uh, look great,” I say.

“Now it’s your turn,” she says. I’m a bit nervous, but I start by taking off my shirt. I have a decent-looking figure and a bit of muscle, so I shouldn’t feel self-conscious, but it still feels a bit weird. Then, I slowly pull down my pajama pants. It pushes down my erection until I get down past it, and it flings up. I step out of my pants, and stand there, naked. She stares at my dick, even though it isn’t that big; only about 5 inches. Sam walks over to the bed, and climbs onto it. She lays on her side, holding up her head with her arm. She pats the bed with her hand.

I walk over to the bed, and climb on with her. She pulls me closer to her, and adjusts herself to be on her back. She spreads her legs as I kneel in front of her. As I sit there for a moment, she reaches forward with her hand, and grabs my cock.

“You’re so hard,” she says. “I bet you’ll fill me up so good. Aren’t you excited to blow your load inside your hot sister?”

“Wait,” I say. “What if I get you pregnant?” She laughs.

“Don’t worry, you won’t. I’m on birth control—you know, in case one of those guys on Tinder decides to swipe right.” Again, she laughs. “Now, go ahead and fuck me, big boy.”

I look down between her legs. Sam’s wet pussy sits there, spread wide, ready to accept me. I carefully get on top of her, putting my arms on either side of her, my cock ready to thrust inside her. I slowly slide it in, as her facial expression changes from a seductive stare to a look of mild ecstacy. I push my full length inside her, with little resistance thanks to her natural lubricant.

“How’s this for your first time?” she says, looking at me.

“I-it feels good,” I say.

“It’ll feel even better once you get to put your load in it,” she says. I begin gently thrusting in and out as we lock eyes. Her breasts shift slightly with my every push. I look down, gazing into her chest. They’re round and firm, just like the ones I’ve seen in porn.

“Does that get you off, staring at your sister’s boobs?” she says. I look back.

“Oh, I-I’m sorry,” I say, continuing to nervously put my cock inside her.

“Keep looking if you need to,” she replies. “You’re a growing boy, you deserve it.” I look back down, starting to lose myself in the act. I pick up the pace a bit, and my head starts to empty as I use her hole. I hear a wet slapping noise as I slide in and out of her creamy pussy.

“It’s so wet,” I mutter a bit louder than I mean to. Sam just giggles.

“I-is this wrong?” I ask. “I mean, you’re my older sister… we grew up together, sorta.”

“That doesn’t matter now,” she says, looking at me. “We both have urges, we’re just helping each other.” I pick up a hint of breathlessness in her voice. The emptiness in my head starts to grow, and I begin to stop worrying. I give in to my instincts, starting to get rougher with my thrusts. Sam starts to moan and grunt, like I’d heard her do through the wall.

“Oh…fuck, yes!” she moans. “Give me your cock!” I start to pant, putting all my energy into the task at hand. The noise from her crotch gets louder as I slam in and out of her. My back arches forward, as I feel a tingling sensation in my groin. It’s like what I feel when I masturbate, but much more powerful. I feel her fluids splash against me, soaking my thighs. The feeling in my dick gets stronger, as I start to lose my rhythm, instead opting for wild thrusts.

I can tell that Sam is getting closer to orgasm, as her moans and pants get louder.

“I-I think I’m about to cum,” I sputter out, barely able to speak.

“M-me too,” she says, unable to maintain eye contact. I look at her; her face is bright red, and she has a look of pure ecstacy. Suddenly, I feel something in my balls, and then an odd feeling travelling up my shaft.

“Oh God, it’s coming,” I grunt, continuing to thrust like an animal.

“Oh—fuck, yes! Give your sis a nice, big creampie!” she moans, gripping the bedsheets with her hands, and wrapping her legs tightly around my body. Finally, I feel it; ropes of cum shooting out of my tip. I continue to push in and out of her as Sam reaches orgasm as well, spraying liquid all over my legs. I start to slow down, milking every drop inside of her. She pants loudly, letting go of the bed, but keeping her legs wrapped around me. Eventually, she relents, letting her legs relax to the sides. I don’t pull out quite yet, instead flopping onto her, exhausted. Despite an inability to catch her breath, Sam begins to speak.

“How—how did it feel to cum inside a real girl?” she asks, exasperated. I take a moment to respond.

“T-that felt… s-so good,” I say, between breaths. Finally, we flip over onto our sides, looking into each other’s eyes. I pull out, letting my slowly softening cock rest on her thigh, still releasing the last drops of my cum. Before I can realize what’s happening, she pulls closer to me, kissing me on the lips. I can’t take even a second to think before she pulls back, looking into my eyes.

“I love you so much,” she says. I’m bewildered for a moment, before I look into her eyes. They’re a shiny shade of brown, illuminating her face, which I finally take a moment to look at. And even though she’s my sister, I feel something.

“I-I love you too,” I respond. She smiles at me, and brings me into an embrace. She puts my face close to her chest, but I don’t complain. I return the embrace, wrapping my arms around her as well. She pulls a blanket over us, and we sit there for a few minutes, appreciating eachothers’ warmth. Eventually, though, we fall asleep in our tight hug, awaiting the day yet to come.
