I never tell my stepbrother, Andreas, no when he wants a massage. We had finished up after soccer practice, and Andreas slapped me on the butt and asked for a rub. He laid down on the bench, and I grabbed the lotion, squirted it out on his back, and started rubbing. We were both in our jocks, and it’s been a while since we were this intimate. I mounted his back, and my crotch was rubbing against his ass. I got an instant erection. I pulled his jock down and got my hands on his bare ass, then my lips. He had me too hard to keep my jock on that I had to take them off and feel his skin on my cock. His dick was too hard to keep pressed against his stomach, so I flipped him over and let him rub it on my hole. But it was a give-and-take kind of day as the tip of my cock pushed against his hole as I stroked him off.
