My brother and I had just finished playing a game on the computer. I was so horny I started smelling his boxers that were laying on the floor. He laughed.
When he rolled over on his bed I put my hand in his pants and started massaging his butt. Eventually, I reached over to touch his very nice cock, he then started jerking me off too. I finally came and so did he. We still do it a lot to this day.
