I never would have believed it had I not seen it myself. I had heard in school that my brother was hung like a horse. I'd even heard him telling his friends that women didn't really know how to suck cock. But I never would have believed... Well, let me give you a little background information first.
My brother, Jeff and I are twins. We're both 18, in our last year of high school. Jeff is about 6'3", with quite a killer bod. I am 5'8", with a typical 18 year old girl's body. I am athletic though, so it's tight too.
So anyway - back to my story. Well, you know how siblings are inclined to borrow stuff from each other. I was walking into Jeff's room, thinking he was out. And there he was, on his bed - with his legs bent back over his head - with his cock in his own mouth.
Now I've never looked at my brother that way before - but shit - imagine watching some guy suck his own dick. That thing looked so long, and as thick as my wrist. I'd never seen anything like it before. And my brother was going to town on it - sucking it like nothing I've ever seen before. My pussy was instantly soaked.
I was so shocked - and turned on I didn't know what to do. He didn't even notice me come in. I walked over to the bed - and he stopped. He looked at me, just like someone who's been busted doing something he shouldn't be doing. I was freaking out. I was so nervous, I didn't know what to do next.
Then I did something I still can't believe I did. I reached out and started massaging his balls - his beautiful, hairless balls. He moaned once, and I asked him if I could watch him. He just smiled, and his dick grew hard again. He put it in his mouth and started sucking. I was so turned on, I put my hand in my panties and started rubbing my clit - while I still had one hand rubbing Jeff's balls.
