I grinded my Brother By accident

incest

So this is my most embarrassing story.

At that time i didnt knew what to do.

Im a 19 years old white girl with black Hair. Im skinny and most men would like to fuck me for sure. I have b sized Breasts. Im Not a Virgin anymore but only had Sex once. Most of the time im masturbating. And i enjoy thinking about forced orgasm in Public. Sometimes when i get the urge to masturbate in Public it makes me scared because my lips are very big...like, really thick and it always feels like im going to cum in public and i have to Fight it. But i guess this Fantasy made it all happen much easier. I also have to admit that i actually orgasmed in a Bus once. Secretly rubbing myself against a seat. So this wasnt helping either.

My Brother and me are very close but He is one year younger than me. And WE both still live with our Patents.
He is also jerking of a lot in His room. I can hear it very often because my room is next to His and the flapping sound is really loud.
But He never was attracted to me. Sometimes i tryed to tease him a little but He would always be disgusted for example when seeing my nipple or Something.

But since He is in this age He would get boners Probably just By touching stuff with His Dick i guess. So it was nothing Intentional on His side either.

So here is what happend.

We were on a Trip to the shopping Hall together with Friends. It was a hot sommer so i was wearing just a slip and a skirt and my brother a short jogging pants.

And while in the mall WE met another Bunch of friends from school.

After a nice day we decided all to Go back at the same time and the Bus was super full. Therefore i decided to sit on my Brothers hips. At first a Friend was sitting next to us but Then He stood Up for an old granny. WE knew that granny, she would sit there until the last station. Ours was three before hers. So we were on our own the rest of the way Home.

The Road is also very bumpy. And it was a 25 Minute ride Home when things got Out of Hand.

After some Minutes I started to feel Something between my legs and it was getting bigger.
It took only a few bumbs of the Bus and i knew that my brother was erected. Since He was wearing jogging pants the boner was standing quiet straight Up between my legs, i was shocked at first and closed my legs around it, Pushing the boner Into my lips By accident. Even tough there was fabric inbetween US. I know that He must have felt my thick spongey lips. Because His dick started throbbing. And it scared the shit Out of me.

I was looking at him with wide Open eyes. So He took out His Phone and wrote me a message "please dont Stand Up everyone is going to see my boner, please hide it - its an accident im so embarrassed" - i was shocked but i could understand him and wrote Back "you are owning me your life for this one" so we stayed quiet about it and i was hiding His boner under my skirt....between my legs...pushed Into my lips... i thought, what could Go wrong, what If He...cums?....what If...i get horny???! And there it was...just the thought made me wet in an instance and i was a little embarrassed. I tryed to ignore it but my pussy lips started to fill Up with blood and got even more plushy and His throbbing dick was making me extatic. I was starting to tease myself Into agony..dont cum dont cum dont cum...i thought to myself while i was geting electrified....i know it was my brother but i thought, well If he gets an orgasm its a mess but If i could get Off He probably wouldnt notice. No one would i did it once before.

So i started to move a little bit Forward to get His boner really squeezing against my lips while closeing my legs harder.

I then just wiggled here and then...good that felt so good. I was really building Up until He wrote me again "what are you doing? Please stop moving" - "im hiding your boner better and i cant stop moving because of the Road and Bus" - "but i will have an accident"....i was shocked to read this, i knew that this means He was close to cumming...but i was too "get yourself together its just 10 Minutes Till home" and Then i looked angry at him.
But yeah i was on the brink to cum too. It was way to tingling already down there. I thought If i can cum Faster than him i can stop wiggling and He still wouldnt get off. Perfect plan!... NOT.
Well of course thats a stupid idea but i was so horny and in agony....just two or three more rubs. I was moving a little bit in circles.... Getting Close...oh god...im cumming....just one more round...but then what was that?! His dick started to Pulsate and Pump. I immediatly stopped moving in fear. I knew this feeling from my first time... oh No... did He?....did He cum? I looked at him in shock...He was so embarrassed and said :im so sorry sis, but you didnt stopped moving" - He was close to crying. I just said " its Okay we will get of the Bus in a Minute anyway" hiding my face for what i just did.

I could Not believe myself what i have done. I grinded my brother to orgasm. He looked so abused Afterwards. He really didnt wanted that and i forced him. But did He know? It seemed like He thought it was all His fold.

After WE came home i tryed to talk to him but He refuesd and begged me to never Tell anyone. I felt so sorry for him. I made him cum. It was Not His fault. But i also couldnt Tell hin the truth. So i promised to hin to never ne mad about it and never tell anyone.

And We never talked about it since. I also lost my touch for forced orgasms in public. Grinding my brother always comes Up in my mind and Then im to embarrassed myself to continue.

So yeah this is the Story hope you enjoyed it.
