I'm really looking forward to doing this again, but next time, on top of the porch, or maybe, on the driveway!
I open the back door and step outside. It's cold and quiet; a little too quiet. Judging by the neighbors' lights (or lack thereof), I assume they're not home. I stretch in excitement, take my shirt off, and hang it on the backyard gate. The same I do with my shorts.
In just my boxers, I walk towards the porch. I slip my hand inside them and pull out my stiff penis. From the excitement, I'm already wet, so I lick the pre-cum off of my penis and then slowly begin stroking it. I dream of the girl next door watching me play with myself. Oh, if only. With my left hand, I pull off my boxers and walk around the porch, maintaining my stroking streak.
Shortly after, I reach an orgasm. I quickly grab my boxers and use them to catch all the cum. On my way back inside, I pick up my shirt and shorts and shut the door behind me.
