Todd, my older brother knew that I, Bethany, his younger sister, got super horny after a bike ride to the park and that my horniness made me crave sex more that an 18 year old girl who was just graduating High School should. I loved the thought of having sex after a bike ride to the park...the seat and vibration of the seat gets me so horny and moist.

As soon as the weather turned warm enough, my Mother told Todd that he should take me on a bike ride to the park.

Mom, I can go myself. I told her

Yes dear but you will have a lot more fun if you go with someone and who better than your handsome and loving brother. She said with a smirk

So we went and by the time we got to the park, its really only a couple of miles away so it wasn’t that long, I was so hot and bothered I could barely stand it. So Todd, leads me around the park to a little gazebo I had never seen before, and we park our bikes and he takes my hand and leads me into the gazebo. I mean we were in the Gazebo but it was completely open and anyone could see in, if there was anyone there. Luckily there wasn't because as soon as we got into the Gazebo Todd grabbed me and kissed me, like really kissed me tongue and all. And being so horny I completely melted, Todd reached around and under my tee shirt and he just lifted it right over my head. Of course I raised my arms because that’s what you do right? So like a minute after we got there, I was making out with my brother my shirt off and my little not even A cup tits exposed to the world.

But that wasn’t enough for Tommy because I felt him unsnap my jeans and push them down over my little boyish ass. So of course, I had to step back and pull them off along with my panties and like two seconds later Tommy had two fingers up my snatch and I was coming hard on his hand without him having to do a damn thing.

As soon as I came down from my cum Tommy picked me up and laid me down on a bench in the middle of the Gazebo with my legs spread and my pussy exposed. He pulled off his pants and then WOW! He just slid his hard cock into my cunt. No asking, no preparation, just slid the damn thing in.

And what did I do? I came again with his cock pushed deep as it would go in my sopping cunt. And I kept cumming again and again as he pumped in and out. I was wild and wrapped my legs around huis waist and met his every thrust. I was a wild woman, girl, whatever, panting I begged him to cum. He asked where and I replied, “in me, in me, in me” not even pausing to think if it was my safe time before he flooded me with his hot sperm. It felt great, perfect!

It took a few minutes for the both of us to regain out breath. I sighed as he slid his cock out of me. I still wanted more and he knew it. But, the meanie was depriving me.

I got up off the bench and sort of sheepishly got dressed. Todd still had his pants down and his cock was as hard as it has been. The he said, didn't you forget something?

Huh? I said.

You forgot to suck my cock and drink my cum. He said.

OMG! I am so sorry I said and dropped to my knees and took his turgid member into my mouth. It was actually the first time I had had a cock in my mouth and to be honest it was only the second time I had had a cock in my cunt, the less said about the first time the better since it was a few years ago and I really didn’t want it or the guy. I just neve said anything ‘cause like why should I, everyone would just think I was a tramp. And I guess I am a tramp since I just let my own brother fuck the living shit out of me and seriously I want him to do it again and again.

I was licking and sucking for all I was worth when Todd shoved his prick into my mouth and down my throat and I felt his cock pulse and then my mouth was flooded in warm sticky cum and damn it all, I came again. It was amazing.

After I swallowed it all down, ‘cause I know good girls swallowed their boyfriend’s cum and I guess Todd was sort of my boyfriend, or that at least I was a brother fucker and really thought that I would be forever!

Todd pulled his cock out of my mouth and told me I was the best sister a guy could have, so of course I told him he was the best too and that I really wanted him to use me again. That’s what I said, Use Me!, it was sort of degrading, but I really meant it. I really wanted Todd to keep fucking me, whenever, wherever, however. I mean WOW who wouldn’t want to cum like I just had.

Todd chuckled and said I guess we better get home.

So I said yeah, even though I wanted him to fuck me more.

So, of course, the ride home made me horny all over again and I was sort of a dripping mess with Todd’s cum leaking out of my pussy. I mean I couldn't let mom see how soaked I was and the dark spot on my jeans where Todd’s cum and my girl juices had leaked through. But Mom was there right at the door when we walked in. She looked at me and said, it sure looks like you guys had fun. You know Todd, you should take your sister on bike rides more often, that’s why I signed you guys up for the weekend charity bike run. It will be great and I know you guys will have a lot of fun. I even got the last room at the motel in Hornyville so you will have a place to stay before heading home on Sunday. You guys don't mind sharing a room do you? Now Todd, take your sister upstairs and get he out of those wet clothes.
