My Sister and I Have Anal Sex by Ardresac

Explore the provocative and forbidden in “My Sister and I Have Anal Sex” by Ardresac. This tale delves into a complex relationship filled with passion and desire, pushing boundaries and exploring deep connections. Dive into a world of intimacy and allure that will leave you breathless.

But that’s all we do.

Okay, I don’t mean that literally all my sister and I ever do together is have anal sex. We do normal stuff too – going to the mall, frisbee golf, smoking weed, etc.

And it’s not a romantic thing either. At least I don’t think it is. We haven’t started acting differently towards each other or anything like that. We act like totally normal siblings, as far as I can tell – it’s just that sometimes, when we get together… well, you know.

I should try to explain how it started.

_____

When I was 22, I moved out of our dad’s house into a crappy apartment closer to my new job downtown. My sister, Tina, was 19. She had recently graduated high school and was working as a waitress at a restaurant in a nice little shopping center near the house. She still lived at home with our dad. Mom had been out of the picture for a long time.

About a week after my move, Tina came by to visit. She dragged me out to the parking lot, down 3 flights of stairs, to show me her new car. It looked a little too nice to not have been at least partially subsidized by our dad, but I didn’t say anything about that.

“Oh! I almost forgot!” Tina exclaimed, opening the passenger door of her car and bending over to dig something out of the center console. The car’s suspension sagged down on the right side from my sister’s considerable weight. I averted my eyes; her gigantic ass looked like it was about to pop out of her shorts with her bent over like this. As her older brother, it was my sacred duty to look away from such things.

Tina stood back up, shoving herself up from the passenger seat. The car’s suspension squeaked as it sagged farther and sprang back into position. She turned around to face me, and she held something in her hands.

“Housewarming aromatic herbs…” she whispered in a joking cryptic voice, holding a little baggie in her cupped hands.

“OooOOOooo…” I crowded close to her to see, our foreheads lightly touching as we both stared down into her hands. The weed looked dank, and I could clearly smell it even outside with the baggie still closed.

_____

“It’s fuggen awesome that we can just smoke out in the living room like this,” Tina said, setting the bong down on the table in front of her. She was sitting on the couch, I was on a big padded chair that was in front of and to the side of the couch. It’s the kind of chair that swivels around, but it’s not a lazyboy. I’m not a lazy boy.

“I know, it’s insane,” I agreed, still coughing from my last big “reep” from the bong, as we sometimes call them. “I’m still getting used to it. Like… yesterday I started to make one of those little de-smokifier thingies, before I remembered I don’t live with Dad anymore.” De-smokifiers is what we called it when you took a toilet paper tube, stuffed a few of those fabric softener laundry sheets in there, and blew your bong hits into the tube so they don’t smell as much.

We chatted and smoked for a while, then sort of transitioned to watching Family Guy while still chatting back and forth.

_____

This is where things start to get a little weird.

Sometimes, when I’m with my sister and we get really high, she’ll just lay down wherever she’s sitting. She won’t go to sleep though, she’ll keep talking with me and doing whatever. She’ll even keep playing Mario Kart with me sometimes. She usually does okay against me in Mario Kart, but once she lays down and relaxes, the annihilation begins, and she loses interest in the game pretty fast.

She laid down on the couch now, turning away from me, which was unusual. The couch creaked and groaned as she repositioned herself. She wiggled her butt several times as she settled in, which sent waves of jiggles up her back and down her thighs. Then she wiggled her butt some more, which I heard but didn’t see, because once again I had looked away from my sister’s gigantic ass.

Although she faced away, we continued to talk about various stuff, and she even responded to scenes happening in the show, which I now watched intently to keep my eyes away from places they should not be.

She continued to wiggle her body once or twice every few minutes while I purposefully kept my eyes away. At one point I looked over, and it was like her shorts were wedged into her ass at the bottom, basically exposing the entire bottom half of her ass, though not actually exposing any of the actual crack itself (Thank God? I guess?)

I looked away again, but I told Tina about the problem.

“Uh, Teen, your ass is kinda hanging out,” I said as casually as I could.

“Oh, jeez,” Tina said, sounding a little embarrassed. I was still looking away, but I heard her adjusting her shorts, the couch creaking under her as she moved around.

Tina sighed. “Better?” she asked, still facing away from me.

I turned back to look at her, but the problem was not better. Her shorts now covered the bottom half of her ass, but the top part of her ass crack was now exposed. There was only an inch or two of crack exposed, and I would have guessed that that only made up a very small portion of the overall length of her ass. I did mention that my sister has a absolutely massive ass, right…?

“Uh, it’s still kinda hanging out…” I said awkwardly.

“Oh. How’s this?” Tina asked before abruptly pulling her shorts down, exposing almost all of her gigantic ass to me.

I swallowed. I hoped my sister did not hear it. I tried, but I was not able to look away from her. It went against everything I knew and understood, but for some reason, the sight of my sister’s bare ass was exciting me in my pants. I tried to stay calm, but at this point I could not look away.

“That’s not really better, try again,” I told her, trying to keep my voice as even as possible,

“Hmmmm” she made a thoughtful noise as she used her right arm to “try” to reach back and pull her shorts back up. But in the process, she grasped her right ass cheek, pulling it up and for a brief moment and exposing her asshole to me, which looked absolutely tiny in between her massive white ass cheeks.

She continued to “struggle”, pulling her ass apart several more times before laughing and saying, “I can’t reach, I’m too fat! Can you help?” She giggled a little more, and the motions of her laughter sent jiggling motions across her body, especially her ass.

“Do you REALLY need help dressing yourself? What are you, FIVE?” I teased her, but still I stared at her body. Her ass was bigger than any I had ever seen. I guess I already knew that before that day… I just hadn’t ever thought about it, for obvious reasons:

She’s my sister

She’s a little overweight, or maybe a lot, not that that was ever a concern of mine because:

She’s my sister

Duh?

“I’m so tiiiired,” Tina pouted, and again she pulled her right ass cheek up. But this time, she did not act as if she was trying to reach the waist of her shorts, and she held herself open for several seconds. “And I’m too high,” she added as she released. Her ass cheek bounced boobily back into place. I was not able to see her vagina — her shorts were covering it — but I got the best view of her asshole that anyone could have hoped for.

I mean, I wouldn’t have wanted to see her vagina anyway. Obviously.

I sighed as I stood up and slowly walked over to the couch, where my sister lay on her side facing the wall, with her whole entire ass way way out of her shorts. She wiggled her butt as I took the few short steps. I didn’t look away from her. I couldn’t look away from her. What was happening?

I knelt down in front of the couch. Tina’s ass and thighs took up most of my field of view. Her shorts were scrunched into a relatively thin band around the base of her ass. Had her shorts not been there, I think her vagina would have been clearly visible.

“Okay. I am now pulling your shorts up. Up your smelly ass,” I joked as I slowly pulled her shorts up. My thumbs sank into her flesh as I pulled them up over her ass. This was a really weird day.

“Welp, problem solved,” I said as I stood back up and walked back over to my chair. “Crisis averted,” Tina agreed.

But when I sat back down, I looked over and Tina had pulled her shorts back down again. What the hell?

“What the hell?” I asked her.

Again my little sister reached back and held her right ass cheek up.

“Oh, God, they came down again, didn’t they?” she said quietly. She was giving me such a great view. She released her grip. I was sad that she did. Her ass jiggled back into place, an ocean of flesh settling back into position.

_____

This was all extremely disturbing, insanely weird, and wildly exciting.

I stood up and began to slowly walk over to the couch. My sister’s huge ass wiggled provocatively as I did.

“This is so ridiculous…” I sighed as I got down on my knees in front of the couch again, in front of my sister’s giant naked ass.

“I know… I’m sorry…” Tina spread her ass open again in another “pretend” failed attempt at pulling her shorts back up. I was so close now. Why was she doing this? I no longer even thought about trying to look away. The Ass was So Phat. I love my little sister so much.

“It’s okay, I can help you,” I said in a strange voice as I pulled her shorts up again. She wiggled her ass and hips as I pulled up, concealing her big butt yet again.

This time I held the waistband of her shorts firmly against her body.

“Okay — does that feel secure?” I asked her, sort of pressing her shorts against her body, making sure they were really secure…

“I think so!” Tina said. I slowly removed my hands from her and returned them to my sides. Just then, Tina lifted her ass and quickly pulled her shorts down again, right in front of me. The couch groaned when she planted her naked butt back down. She wiggled and jiggled her ass playfully at me.

_____

“I really hope this whole pants problem isn’t contagious,” Tina groaned.
