My younger brother has always been a bit of a selfish person, and for the last 18 years he has always made sure to put himself first. He always wants something now, without delay, regardless of who he inconveniences. Up until a few days ago I hated that about him, but it has it's rewards.
I was in the bathroom early one morning when I heard a hard knock on the door. It was my brother saying he needed the shower now to get ready to meet some friends. I told him to fuck off and wait, but he'd have none of it. He opened the door and barged right in while I was sitting on the toilet.
"You fucking dick!" I said. "Wait your turn asshole!"
"I did wait, you're taking too long." he said as he pulled off his t-shirt. He was wearing only his boxers and I was a bit taken aback by what I saw. My brother had a nice body on him. He had been wrestling all through High School and was really lean, and muscular.
"So you're just going to shower in front of me you perv?"
"I'm the perv?" he asked. "You're the one looking at my cock." And with that he let his boxers fall to the floor. I was amazed to find that my little brother was hung like a pony. His cock was not the longest I had seen, but it was thick, and veined, and the head was flared so nicely. I was staring at it for a good few seconds before I remembered it was my brother's dong I was admiring. He stepped into the shower and closed the dark green curtain.
I stood up and had to collect my thoughts for a second. I was really horny after seeing that massive meat between my brother's legs. It was so wrong, but I wanted to feel it in my mouth. I took off my tank top and shorts and quietly walked to the shower. I pulled it back in a quick yank and stepped in behind my little brother. He must have been expecting it because he didn't turn around when I came in. I wrapped my arms around him from behind and kissed his neck and shoulders as I mashed my tits into his back. He moaned as I played with his nipples before letting my hands slide down his wet soapy body to his rising cock. I wrapped my hands around it and was shocked to find my fingers could barely get all the way around his shaft. I stroked it slowly with my sudsy hand and felt it grow to full hardness. I was in awe of his package.
"This sure is a change for you sis." He said without turning to look at me. "Like what you have there?"
