My favorite place to masturbate is outdoors in our back yard. We have a fenced yard so I don't worry about being seen by neighbors.
I love sitting out in the sun when it is warm and start by slowly playing with my cock. My wife tells me I must love looking at my penis because I go nude most of the time at home.
I do love holding my cock. It feels so good in my hand. I was out on the deck just yesterday. As I played with my cock and it started to feel real good, I got up and walked to the middle of the yard. If our neighbor had come out on her deck, she could have seen me. The feeling of being nude outside is like nothing else. And to be masturbating out there in the day time was wonderful I continued to stroke my cock and moved so I could see the reflection of myself in the glass on our back door.
That was all it took for me to shoot several streams of warm cum onto the grass. If you have never masturbated outside, I highly recommend it.
