How it all began

Note : This story is completely fictional!

It began just about 6 months ago. My brother is two years older than me. I always knew my brother was a perv but I never really saw him do anything. One day we were on vacation in the outer banks. It was a lot of us there mostly family but some friends. I had to sleep on the same floor as my brother but in a different room. We had to share bathrooms though. One night I had to go to the bathroom. I got up and noticed that the light was on in the bathroom but i didnt hear anything so went to go to the bathroom. As i got closer i happen to notice my brother in there on the toilet jerking off. I was caught way off gaurd. I dont know why the only thing in my mind was that his dick was bigger than I thought it would be. Anyway as i was about to turn away he let out a little moan that caught my attention. All of a sudden he shot out sperm all over his stomach and chest. He kept stroking as the sperm dripped down his hand and balls. He let go of himself and i snuck back to my room. The next morning as I went to the bathroom I couldnt help but to think of what I saw the night before.

One thing that really caught my attention as I was going to the bathroom was that if you looked into the miror with the door open you would be able to see about where i was standing. I opened the door to test my theory and there is no question that he could have seen me. I dont know why but the thought of him jerking in front of me on purpose turned me on.

In order to see how he would react to me in a sexual way i came up with a plan. That day he was the only one in the pool. So i put on my bikini but I made a nice little cameltoe on my pussy. My pussy is a little bit puffy and since I shaved you could see the outline of my pussy lips really well. I waited until he got out the pool and then I walked out. He got an instant woody and jumped back in the pool. It worked! Now I knew he was turned on by me.

I waited until we went back home before my next move. For about a week I walked around with only my pajamas with no panties or bra. My nipples were hard like all the time. I wanted to get him good and horny. I could get away with it because my mom was at work so it was just us two. This time I wanted to return the favor of letting him watch me finger myself. I went to my bedroom and recorded myself on my phones video recorder. I "accidentlly" left it in the bathroom in the gallery mode knowing that he would look. It worked. I heard him jerking off to it 20 minutes later. I noticed that he texted it to his phone.

We still didnt talk about it but later that day I found his phone in the bathroom. There was a video of him jerking off in the kitchen.

It was about a week later when I decided to let him in on the fact that I knew what was going on in his mind. So I made another video of me fingering, but I sent it to him myself. I titled it "look but dont touch".
After his phone went off signaling that he got the text he came to my room and knocked on the door. I told him to come in. He walked in with an obvious boner. I was naked but covered up. He looked at me without a word. I pulled my covers off slowly and just let him take it in. I hadnt touched myself but I could feel my pussy dripping wet. He only stared with a little grin of disbelief.

I opened my legs a little wider and just parted my lips for him. He pulled his dick out and started stroking. It took him all of 5 seconds to cum. It had to shoot about 4 feet. I just kept fingering my pussy.He started jerking and came again about 5 minutes later.
Since then we masturbate for each other all the time. The only rule is "look but don't touch".
