Not my brother but half-brother. My dad’s first wife died in an accident when my two half-brothers were 8 and 9 respectively. He remarried to my mom and had three daughters (including me). We have a great family. By the time I was ten, both my half-brothers were in college – so it really was like two separate families. I was eighteen at the end of my senior year, and I won a basketball scholarship to a major university, and was using the summer to prep for it. I’d gotten down to 120 lbs of muscle, but I needed a lot more work to get where I needed to be.
That summer, Don visited our house with two friends. I always thought Don was good-looking, but these two friends were hot. They laid-out in the backyard tanning by the pool in speedos. All three were muscular, washboard stomachs, and oozed manhood. I stared at them from my upper-story bedroom window. More than once, I fingered myself to orgasm. One day, Don came inside from the pool and went to the bathroom just inside the hallway. I didn’t know he was in there, and I opened the door just as he was “putting it away.” I stared at it, and he at me.
