It was 9:00am on a cold autumn Saturday. I had just finished a nice long, hot shower after going for a mountain bike ride in the nearby park. I wiped down the shower and proceeded to dry my body off with a towel that was fresh from the dryer. I stood for a moment looking into the large mirror in the bathroom. The steam on the mirror was dissipating and I could begin to see myself clearly. I was somewhat surprised to see how muscular I had become. It was a good season of biking and I had spent many hours on some of the toughest trails in the area. I had lost about 25 lbs and could see that my legs had become very muscular. My chest had also gotten quite muscular and my biceps were bulging without having to flex them. As usual, whenever I looked at my cock in the mirror I had to play with it. I had just trimmed my brown pubic hair to a thin layer and shaved the sides a bit to create a neat patch. It made my cock look longer which I loved. I finished admiring myself and chuckled at my obvious vanity, and headed out of the bathroom into the much cooler bedroom air. I threw the towel onto the bed and strutted across the room to my walk-in closet. In doing so I passed by the large, open bedroom windows which ran from about a foot above the floor to the ceiling. Our master bedroom was situated at the back of the house. I often left them open since I figured that I could not be seen during the day. The light was quite bright outside and the sun was shining from the front of the house so anyone looking my way was facing the glare of the morning sun. It was nonetheless an exciting feeling to be completely naked, facing the back of my neighbours house and yard.
