Okay, my first erotic fanfic.
I know. It seems really bad to start out with. But it's what I made first.
I still feel reeeeally dirty, though. My future works won't be as bad.
Trust me though, you should read till the end.
The Plan.
It's a quiet night in Gravity Falls. Which makes me all the more nervous when sneaking across the room to Mabel.
Besides the creaks the only other sounds in the night that I can hear are some crickets and my sister's breathing. After what felt like an eternity I make it to her bed. She's sleeping on her back with her head facing me, which comes close to the edge. Her strawberry scented soap fills my nostrils. It's going well, I think to himself.
I then take off my shorts and pull out my growing member through my boxers. I stare at Mabel for motivation as I stroke it to life. I stare at her smooth skin and hair gleaming in the moon light.
Once it's erect I risk the first part of the plan to not wake her up when I start to rub the head on her cheek. The sensation was like a shock going through me at first. I place my left hand on her head and start rubbing her lips. I feels like I'm going to pass out from the sheer pleasure.
I can feel her lip balm as my sensitive tip circles her lips. Once it feels like I'm close to cumming on her face, as much as I would love that sight, I stop myself. When I'm about to pull back Mabel starts to lick the head. I quickly look down to see that she is still asleep and must be dreaming about a sucker or something.
Mabel mumbles in her sleep as she continues to unknowingly lick the tip of her brother's dick. I stare at her Tongue lapping at my sensitive head and start to stroke myself. I watch her tongue drag itself from the right of my head to the left and repeat this for what feels like an eternity until she finally starts to take the very tip into her mouth and suck it.
This and the feeling of her tongue swirling the tip sends me over the edge. I remove my cock's head from her mouth, making a bridge of pre-cum, and fulfill my earlier dream of facializing my sister with my sperm.
I shoot jet after jet onto her cheek and temple. I had to refrain from letting out an actual moan. Once I felt drained I admire the sight of my sperm on the side of her face, dripping down to her mouth. She laps up some that makes it to her mouth.
I pull myself out of my stupor when I remember the now ruined plan and realize that I need to clean up the evidence. I head to the bathroom on shaky legs and not turning on any lights so I don't wake up Mabel and get a damp wash cloth. I come back to find that she is in the same exact position and carefully clean her face with the cloth. I use my covered index finger to wipe her soft lips. Before I can get the little that is left, Mabel licks it away in her sleep.
After I'm done with the evidence I crawl back to bed and quickly fall to sleep.

“Kids! Wake up!” I open my eyes to see Mabel staring at with the morning light on her. “I made some... thing for breakfast and I want you to try it before me!” our uncle concludes his wake up call to us.
The day seems to go by extra slow as I wait to start the plan over again tonight. I have a suspicion that Mabel might some how know about my failed attempt on her last night. She repeatedly stares at me with an expression of questioning and very slight contempt.
I better finish the plan tonight before it's completely ruined.

The day had finally ended and I am now watching Mabel sleep from my bed. I get up and repeat the process of sneaking across the room again to her bed. This time though I don't play with her mouth, I instead survey the situation. She's on her side facing me and she has already kicked away the blankets.
I move down the bed and carefully lift up her long night shirt up to her chest, just below her nipples. I look and see that she is currently only wearing panties. I gently grab them and slide them through her legs; she doesn't react.
I keep her underwear on me and carefully climb onto the bottom part of the bed. I lift up her left leg and place to the side of my head, on my shoulder, and stare at her beautiful pussy.
It's completely bald and is slightly flushed at the lips. I rub my sister's sex with my fingers to admire how clean, smooth and soft it is. I use two fingers to spread apart her pussy lips and stare at the lush pink flesh. I can smell her sexual scent through the abundant strawberry shampoo she uses.
I stare at Mabel's pussy for another moment before I taste it. I trail my tongue around her lips and start to spell out the alphabet.
“... Hmmm...” When I hear Mabel groan when I get to “K.” I slowly lift myself up and look at her face.
Her mouth is slightly open, her breaths are stronger and her entire face is flushed but she is still very asleep. I look down and test how wet she is my inserting my middle finger into her pussy. Even for my finger it feels incredibly tight, yet soft and hot too. She's ready, I think to myself.
I remove my shorts and underwear and expose my erect member. I gently place her legs apart and sensually run my hands on her torso, from her hips to her budding chest. I repeat these motions until I place my hands to her sides, are sexes rubbing together, and stare into her face. I enjoy her minty breath before I kiss her, to let her taste herself. I enter my tongue into her mouth and soon her tongue starts to sloppily wrestle with mine.
“Mabel,” I whisper, “Wake up. Your about to have sex with your brother,” I aim and slowly enter a third of my cock into her and slowly pull out until just the very tip is in.
Mabel lets out a small gasp and drowsily opens her eyes. “... Dipper? What are yo-AAH!” I interrupt her when I shove my entire length into her. She grips the my shoulders and bends her knees in response. Once she starts to be too loud I shove her panties over her mouth and hold them down with my hand to muffle her yelling.
Her waking up is actually part of the plan. Stan doesn't sleep with his hearing-aid so I don't need her to worry about making too much noise. But I want to be careful and I really wanted to shove those panties into her face.
Mabel seems to realize whats going on and starts to feebly push and hit me with her arms while she also kicks and thrashes with her bottom half. She doesn't seem to know that her pelvis, rapidly moving up and down, left to right and pushing back and forth is just intensifying our pleasure.
I use my other hand to hold her down and start to pump in and out of her to get her to calm down. She stops thrashing her hips but I can feel her pussy clamp down on me. Her body is trembling and she seems wetter than ever. This can only mean one thing: she came.
“You're cumming from your own brother raping you?” I ask her. “You're a real pervert, huh?”
Mabel tries to shake her head from under my palm. She's been keeping her eyes clenched shut since she came. Her face is covered with a mixture of tears, sweat and some of her own love juices. When she calmed down I slowed my pace but have been steadily gaining speed. I'm getting close.
“I'm ready to cum, Mabel. Should I do it inside?” I actually remove my hand a little to let her speak.
“No!” She finally opens her eyes and stares at me, pleadingly. “Please. Stop.”
“I'm so close, Mabel.” I take my cock out all the way and then enter it all the way back in. I repeat this again, and again, and again, and again and again.
In.
out.
in.
out
in.
out.
in.
I can feel that Mabel is close again when she really starts to beg. “Please! Outside! Outside!”
I pull my close to bursting cock out and finish myself off on her belly. I also rub the shaft on her clit and watch her convulse with her second orgasm. She grips the sheets and opens her mouth for an almost silent scream and some moans. After a few moments she relaxes with exhausting and just lays there panting with her head facing away from me, towards my bed.
My limp member lies on top of her sex as I look at my own sister, with her shirt up to her neck and exposing her breasts, with streaks and puddles of my sperm going from her pubic area to her lower chest. This sight gives me my second wind. I can feel myself start to stiffen and grow again. Before Mabel can say anything I already pull her in for round two.
“Ah-ah-ah-p-please-ah-stop!”
Besides Mabel's pleas and moans the room is filled with the wet sound of her ass slapping against my groin area.
My sister is currently on all fours and getting a more prolonged pounding. I've removed her shirt and am not covering her mouth anymore but she hasn't screamed for help yet. She's only really been begging me to stop.
“D-Dipper! Please st-AH-op this! I-I promise I won't tell anyone. We can pretend that this never-UGH!” I give her long beautiful hair a tug like I've been doing whenever she lowers her arms. She lifts herself up again and continues. “This isn't right! I'm your sister!”
I take her left ass cheek in my hand and pull it over with my thumb to get a better picture of her ass hole and my cock going in and out of her soaking pussy.
From the sound she's making and the tightness I feel I'd say that Mabel just had another mini-orgasm. She's had two others since we changed positions.
I take this opportunity to grip hers hips with both hands and pump much faster, seeing as I was close too. The new stimulation as she is already have a small orgasm brings her over the edge. Her current climax grows into the biggest one she's had so far. She covers her mouth to stop a scream as I give her a few more thrusts before I take out my member and spray my sperm on her ass and sex.
We collapse into a sweaty naked heap. I lie on my back as Mabel rests on her side like before.
After a few moments of catching my breath, I speak up. “So... what did you think?”
Mabel tiredly lifts herself up and looks at me through he wild looking hair and says, “Awesome.”
She plops down on my right arm and places her arm over my chest. “So it went according to plan?”
“And then some. I only told you to 'rape' me once,” she says while making her fingers into quotation marks.
“Your plan didn't have many details.”
“Well, I knew that you wouldn't want to hurt me or anything-which you didn't by the way-so I left it up to you.”
“I'm still not sure about the idea of this fantasy of yours.”
“I just wanted to try something out is all. If you don't want to do it then I'm fine with that.”
“That's good to know.” we rest in the same position but try to stay awake as to clean up later.
“...[pfft]”
“What?”
“Oh nothing. I was just thinking about how funny it is to think that you could overpower me.”
“Shut up.”

Told you that you should have finished this.
On a more serious not: just because I wrote something like this doesn't mean I condone what's happened in this story. I absolutely hate the idea of victimizing anybody like that. All it does is fill me with blood thirsty rage.
I'm not all that proud about the incest either.
I feel really gross right now.
Please review so I can improve on my next story, if there even will be one. And feel free to message me. Unless you're a hater of something.
