I did it with my sister and it was wired

So this is an actual real incident. Everyone who has a beautiful sister knows these Moments but probably never pushed it. also its nearly 17 years ago. But yeah, i did. By "accident". We both were still living together with my parents. At that time Internet was still Something new. Internet on the Phone was very expensive and defnitly Not for porn and an average houshold wouldnt have a Computer for everyone. More like one or two for all. And porn magazines were very difficult to get. Since you had to buy them in Person which, AS you can Imagine is very embarrassing. So maybe the younger people reading this will never get into a Situation like that or well maybe diffrently. The thing is - In my time you jerked Off to everything that was just a little erotic because of that lack of porn. And your own sister was defnitly a thing, especially when she was older than you. Also even though a lot of girls do Masturbation - I dont think it was that common in my Village at that time. Or at least in my Family. I have never heard my sister Masturbating while she defnitly must have seen me at least once geting of somewhere in the house. It was just like that 17 years ago.
Also, even though most of us had Boyfriends and Girlfriends, things usally didnt went to fast either. IT could take weeks of dating even before you could just rub a womans vagina or see her breasts. Sex could take months. So you could say that basicly everyone was more or less horny and therefore thirsty for sexual releave in some way and sex was a taboo theme. And i think this is why this was actually possible to happen.
You see my sister and me often annoyed each other. Like other normal siblings. Since she is older, she usally started this and i end it by hiting her on the head. Not to hurtfull, just enough to keep her mouth shut. She was usally laughing while i did IT because she techniclly won since i lost my temper.
I dont know today what it was that day but things sort of escalated.
I cant remember the reason anymore for sure but i think it was her making random stupid sounds while i wanted to watch TV. It was summer and She was wearing a skirt and a string that day while i wore a Boxershort with a pee hole. Both of us a Shirt. I didnt saw her boobs that day. I mean i had seen them before but not this day. I did not even saw her pussy completly. So here is what Happend. She annoyed me and as usally i would go after her. She ran into her room and was siting in her chair cowerdly kicking after me to get me away. I tryed to get close of course and I dont know why (okay i actually do) but it sexually aroused me to Spread her legs to get Close. I got some nice brief looks between her legs and i kinda didnt wanted to stop until i had a good view. So i got wild and pushed both legs fast enough and ran her over. I also had already a semi erected boner. But while i pushed myself foreward the chair broke. And i fell on top of her. I didnt penetrated her. This is not possible like that but my semi erected penis was defnitly resting on her pussy mount. I felt it and while we both looked into our eyes - in shock of the broken chair, my dick started to grow to his maximum size. I also had an absolut rush of hornyness and since i didnt knew how to deal with this Situation, and she absolutely felt my dick too, i went along and hit her face. We were wiggeling a lot around and of course i pushed and tryed to rubbed my penis on her a little. IT was to tempting. She tryed to grap my hands and screamed to stop while laughing. But WE never really seperated. im sure she was rubbing her vagina on me too. It just felt to good to stop and since her skirt had fallen over her stomach i could see some glimbs of pussy lips. So i kinda wiggled my dick out of the pee hole and she got really clinchy with her legs. I was so aroused and horny already and she probably too that we didnt care anymore if we were Brother and sister. Our fighting went on more and more into a wiggeling up and down and then there was it. I actually probed her after several thrusts. Her Slip went to the side and i went in a little bit.
In the exact Same Moment she also grabed both of my hands with hers and we both stopped for a second and looked into each others eyes. You all have to Imagine this took Place in a matter of a minute after falling to the ground. So i was probing her pussy and we were holding hands and looked into our eyes. And i pushed it deep inside her. I was in sexual agony. i had to do it even if i would regret it. Her hot warm moistered pillow of a pussy was to wide open for me. But also while i did that i tryed to get my hands free so we started to wiggle and fight around again. But we defnitly were fucking. She tryed to fight too but her moans and the continued eye contact Said it all. It didnt took Long anyway since it was my first time - we just fought for like 5 thrusts before i blew my load deep inside her. We still had eye contact so i was pumping my load while we both looked at each other. And she defnitly allowed it. She was curious to know what would happen and well she got her answer. After i finished i pulled out and stood up and said Something like "well dont annoy me again" - what she did Afterwards? I dont know. Cleaned herself i guess. I was completly confused and a little scared. So i went into the living room waiting for trouble. But Later she came back into the living room eating cereals. And it was so strange. She Said nothing bad. We talked about the Show and We acted like nothing happend even though it defnitly did. Or like it wasnt even that big of a Deal.
The whole thing was crazy. I was so comfused.
Seriously every Brother at least once has stand between his Sisters legs. Maybe Not on a Chair but these Situations have happend in other ways. And to be honest without her help the slip would have never left its place either. She defnitly wiggled her ass left and right to roll it to the side.
So we both wanted IT and took Advantage of the Situation.
Why not just talking to each other to fuck you Wonder? Come on guys you dont ask for this. And even though there are sexual tensions No one would openly admit them. Especially not in my time. But yeah this is how it happend the First time.
And This dear guys is how it really can happen and has happend. Just some couple of horny minutes in both sides.
