Ever since I got my own apartment, I have been able to walk around naked like I couldn't do when I was still at home. Most days when I get home from work, I strip down and stay that way until the next morning. Since the glass door in my living room faces a line of trees I don't have to worry about anyone looking in, so I can masturbate on the couch and no one would know it. The longest I have gone with no clothes was when I took off a couple of days from work and had a four day weekend. As soon as I walked in that Wednesday, my clothes were gone and I was free until that Monday morning. I still had to walk outside to the mailboxes, but I waited until after midnight when the lights went off. One of the nights I even jerked off doing this, wearing nothing but flip flops and an erection.
I wasn't hard the whole time, but for a good part of it my penis was sticking up and I was playing with it. I don't remember how many times I came, but it was a lot. One of the days I would lay on the couch, masturbate, cum, fall asleep, then start masturbating again when I woke back up. I didn't want to waste a bunch of tissues, so I just let it fly on the table and cleaned it up later. By the time Monday came around my penis was red and sore, but I had to cum one more time so I went onto my balcony and did it in the cool air before work. It was tiring and it hurt to have an erection for a couple days after, but damn it was fun.
