My Mom and Dad we're fighting all the time and decided to divorce. My Mom eventually met someone, fell in love and married him. He had two children, a daughter Margeaux (21 years old) and a son Brett (20 years old) from his previous marriage. My Mom and I moved into my stepdad's house after the wedding. My stepsister Margeaux was already living at college at the time, but my stepbrother Brett was there living with us. Brett never really paid me much attention, even though we were only 2 years apart in age. He had school, sports and his friends to keep him busy. One afternoon, I was in my bedroom playing with my video games, when I heard Brett come through the front door of the house, just getting back from football practice.
He shouted to my Mom, "I'm gonna get a shower, I'll be down for dinner later".
I heard him come up the stairs, he passed my room (not even saying hi) and went into his bedroom. A few minutes later, I heard him go into the bathroom, shut the door and turn the water on to the shower. I was thirsty and decided to go downstairs to grab myself a glass of water. When I was coming back up the stairs, the door to the bathroom opened and out walked Brett, with just a towel wrapped around his waist. His tan, athletic, muscular chest and arms still wet from his shower, glistened in the dimly lit hallway. He glanced over and noticed me at the top of the stairs, staring at him with the glass of water in my hand.
As he walked to his bedroom, he said "Beau, come here, I want to talk to you."
As I mentioned, Brett never paid me any attention, so I was surprised and happy that he wanted to talk to me. When I entered his bedroom, Brett proceeded to shut and lock the door behind him. He then started making small talk, asking me about school and my classes and how I liked it. As I was responding to his questions, Brett proceeded to remove his towel from his waste, completely exposing himself to me, and began to dry himself off. His naked 6'2-inch muscular frame looked amazing to me. His ass was small, round and muscular as well, and as he turned, I saw his big flaccid cock, that's the first time I ever saw another man's cock before. I couldn't help but stare at it, it looked really big, and his balls and cock bounced around as he continued to dry himself off. When he caught me staring at his cock, I turned beet red, and quickly turned my eyes away.
He said, "There's nothing to be embarrassed about man. Do you want to touch it? Go ahead" and he walked over to me and put his cock in my face.
I was still beet red, but slowly reached out and touched his cock with my hand. I said, "It's so big."
He smirked and said, "It gets much bigger... see", as it started to grow in my hand. He then said, "The girls I date do things to it, that make me feel so good. Would you like to do that for me Beau? Make your big brother feel really good like those girls do?"
I paused for a second, not sure what was happening and what he was asking me to do, but because I liked that he was paying me this attention, and that he looked so good standing there in front of me, I said, "Okay".
He grinned with a mischievous look in his eye and said, "Sweet, it'll be so much fun getting to know each other better, but... you have to promise me one thing, you have to promise me that you won't tell Mom, Dad, or ANYONE about this... do you promise?"
