I've seen some 750 word stories, and thought that I'd give it a try.
I had got together with my stepbrother, well, more than a few times when we were younger. Each of us were 18 and it was the summer between our Senior year of high school and freshman year of college.
He was the aggressor, but to be truthful, I didn't fight him too hard. I've watched all kinds of porn, and I thought that if I were ever to hook up with a guy, he would be similar to Alex. 6'2", with a solid 220 pounds. Slightly hairy. I suspected that he mangroomed.
One Saturday afternoon, I was in the shower. Alex and I shared a bathroom. I heard someone come in. I assumed that it was Alex, and he needed to pee. This was not something new.
Next thing that I know, the shower curtain is being pulled aside. Alex is stepping into the tub, and I see a 7 inch, hard cock. I stammered, "What are you doing?"
"Relax. I need to shower too. I've got a date, and I'm running late."
I looked down at his cock. It was still hard. "Why are you hard?"
"As I was getting ready to get in, I got an idea that you can help me out."
