I had sex with my sister

So to preface, this is a pretty old story. This happened back when we lived with our parents over a decade ago. But I figured this was a great place to share anyways.

I'd always considered my sister attractive. Never in a "she's hot" way, but more in a "I see why people are into her" way. She was a tad chubby but still had a great figure shape. DD chest I believe, so her body still had a somewhat hourglass shape, despite being a little curvy.

Around the time this takes place, between siblings and step siblings, we had 2 other younger siblings as well as obviously the parents. Given that we all lived in the house, we all still had chores and whatnot. One of the chores she had to do was walk the dog. If I wasn't doing anything, sometimes I'd go with her. We had a big rock we'd walk to that was near the neighborhood, but still concealed enough that you wouldn't see anybody near it unless you were about 5-10 feet away, with how the tree would hang down the way it did. So we'd walk the dog, chill by the rock, chat and bullshit and take a break, then head back. It was pretty typical.

One day we're walking the dog and talking like always, headed towards the rock. I forget exactly what sparked this conversation, but we were making fun of movies or TV or some generic trope where someone will kiss on TV and then suddenly it's all fireworks and sparks over the top crap. One of us had made the comment about going all prince charming frog and just (jokingly) randomly kissing strangers until something clicked. The other person threw out a jokingly "what if we kissed and felt something" reply. Again I forget the exact words but that was the general idea.

We get to the rock and it turns into me basically laughing about "what if, that'd be weird" and her throwing out a "yeah you wanna try and see what happens?" reply. I didn't think she was serious at first so I laughed it off with a "totally" and tried to play it off. She gives me this look that I hadn't really seen before, and puts her arms around the back of my neck and smiled at me. She leans in and at this point, I say fuck it and go in.

The rush of the taboo, the mystery, the youthful hormones, and the fact that I've known this girl in a sexual way since as far back as I can think of, I absolutely felt something. She breaks it, smiles, and we lock eyes as almost a non verbal confirmation, before we went back, this time actually full blown making out like horny teenagers lol. My hands went to her hips, her arms pulled me closer, and my tongue found hers

After a little bit it ended. I didn't really know what to say or how to process it. I gave a lazy humor "so, anything spark" and she laughed and gave me a "oh yeah" type answer.

After that, not too much happened for a while. I replayed that moment in my mind for quite a while. But I didn't have the balls to ask her to recreate it, or how she felt about it. Didn't wanna push and ruin anything I guess.

Fast forward a month or two. We're hanging out in my room and playing games. Some wii game. I don't recall, not like it matters. I genuinely for the life of me can't remember the exact conversation that lead to this, but we ended up talking about dick sizes and blowjobs. We'd always had a pretty open relationship with no filter, so outside of talking about our personal sex lives, nothing was tmi.

Somewhere along the line, she made the comment about how being able to deep throat wasn't a challenge for her. Being a dude, I tried to match her energy and throw out a "Psh couldn't handle mine" competitive shit head sibling kinda way. By no means am I massive, so I honestly had no idea where this came form. Average size, but not some 12 inch monster lol.

She says "I doubt that, prove it" and smirks at me. I laugh it off with a "what, fucking show you?" and she's just encouraging it with "yeah why not" in the most casual way, like I'm playing a hand of cards or something.

My sister asking to see my cock was all I needed to be pretty much rock hard at that point. I stand up (we're sitting on the bed side by side at this point) and her eyes locked immediately onto the bulge in my pants. I unbuttoned my pants and pulled my boxers down enough for my cock to spring out like a wind up toy.

She let out a quick "woah" which was either to me almost hitting her in the face, or to my dick itself, who knows. I mutter "so, was I right" and this girl without slipping a beat, wraps her lips around my cock, bobs her head up and down a couple times, and then just shoves the fucking thing down her throat, almost all the way. I know this sounds like some made up porn shit. But she gags on it, holds it as long as she can, then gasps, smiles, and gives me this cock ass "well I got most of it"

Nothing happened after that, idk if the tease was fun for her or if she was just too nervous to go farther, but that's all that happened at this point.

A few months down the road, me sister and I are in my room with my cousin and watching stuff on Netflix. We all stayed up late and at one point, my cousin fell asleep on the floor next to the bed on the beanbag.

After the move ended, we starting looking at other stuff to watch. Going to the search, we saw that he had apparently searched for "porn" on Netflix being the dumb kid he was lol. We ended up checking out the results for it and obviously nothing came up. A couple pg-13 and R rated comedies, American pie and sex drive type movies.

I lie down on my side to see the TV, and she does the same. We're still a couple feet apart, but nothing we hadn't done many times. The beanbag is sitting in a way where you can see the TV, and you're next to the bed. So if you looked at the bed, you'd see the whole front of whoever is lying down, and the upper part of the person behind them. That's essential in a sec

We turn on a movie, and during the movie a scene with a girl taking her top off came up. She slowly hscks herself up into me, not quite grinding on me, but still easing her ass against me to where I know she felt me pressing against her.

Eventually it turned into actual grinding, and once my cock was throbbijg against her, I stopped trying to hide it. My hand went to her hips, grabbed her ass, and at this point we're practically dry humping on our side while trying to be quiet.

My hand moves past the elastic of her shorts, and grabs her bare ass. I hear her try and hold in a little moan, so I took that as a green light to continue. I pull my cock out and I'm rubbing it on her bare ass and she's grinding back into me, still trying to keep quiet and not make the bed squeak too loudly.

Again, this is gonna sound like some porno shit but this is legit how it played out. Eventually my horny brain took over, and I started going from rubbing my cock on her ass to pressing between it. My tip was touching her bare asshole, and she seemed to not care. I started doing these half thrust motions, not quite hard enough to force it in, but enough to push against her.

Her moans picked up, and not stopping me, I kept going. I grabbed her hip, and slowly pushed against her as hard as I could. The second my head pushed inside her, she let out a noise that almost sounded like it got cut off mid moan. High pitched then silent. I pause for a sec, making sure she's good. Then she starts pushing back into me. Back and forth. Slowly but just enough to fuck herself without rocking the bed. We didn't finish. Mostly because we kept looking over every 10-20 seconds to make sure our guest wasn't waking up. After a little bit we ended up stopping.

The next day, we're hanging out, working out downstairs on some of the exercise equipment. Everyone else is out. Siblings at a friend's, parents off doing work or whatever they were doing. She's stretching a little sluttier than usual, and dressing a little more comfortable than normal for using the machines we had. At this point, my cock is visible thru my shorts and she's loving the attention.

She asks if I'm enjoying the view or if I'm getting any ideas. At this point, I'm being a little braver so I tell her yes and walk over. She's sitting on the ab machine, and I walk up and put my hand on her thigh. She shivers and smiles up at me. My hand goes to her thigh, up her leg, and to the middle of her shorts. I started to rub her pussy thru her clothes, then slid everything to the side, and slid my fingers inside her. She was soaked and just got wetter as it went on. After making her cum a couple times, after the last one, she grabbed me by the shirt, pulled my face close to hers, and said "fuck me. Now."

Within a few minutes her legs were behind her head, and we finished with her swallowing me. After that we had a pretty ongoing sexual relationship for quite some time. There were some mornings where I'd sneak into her room first thing in hehe morning and fill her ass with cum before she even got out of bed. She'd sneak into my room at night sometimes and give me head. We'd "catch each other" in the shower "on accident" pretty often, and she'd even have nudes that she'd let me "find" on her phone.

At one point, we were dating in a sense. It was like a private relationship where we swapped love notes and talked about meeting and honestly it was pretty sweet. Ever the years, even when she'd have a boyfriend, she'd still fool around with me. I think part of it for her was just sharing it with me specifically. Hell, I remember her telling me "I think you'll like this guy I'm talking to" while she was in the middle of putting panties back on a couple years back lol.

Anyways, happy to answer questions. Thanks for bearing with me. We had a lot of escapades over the years so there's plenty more stories to tell, but this was kinda how it all started and turned into what it ended up
