I was naked and home alone enjoying my favorite adult beverage, doing household chores on a nice, cloudy afternoon. The windows were open and the breeze was blowing through the house. It felt great against my naked body. The smell of rain was in the air.
The alcohol was starting to cause my body to tingle. I poured a second drink to help solidify my buzz. All of the movement while doing chores was causing my to dick to flop around and rub on household objects; I had begun to get an erection. I noticed my stomach was rumbling a little from my Mexican dinner, but nonetheless I was feeling pretty good and having a great time.
The rain and thunder started up. I stepped out on the back porch and walked into the rain. I wasn't worried about privacy; I had an eight-foot fence around the entire backyard The cool rain sent chills down my spine. My dick began to stir, and I couldn't help but tug on myself. I let my hands caress my balls, and then slip between my ass cheeks, allowing my fingers to tease my asshole.
All of the water coming down on and around me gave me an intense urge to pee. I stood tall, took a deep breath in, and let my warm piss flow from the head of my dick. It felt amazing to be naked and free. My stream finally slowed to a few drops.
While standing outside in the rain, I couldn't help but glance around. I was getting a strange feeling that someone or something was watching me. The sky was starting to get even darker. I felt something touch my backside. I spun around quickly, trying to keep my balance in the slick mud. There stood a non-human creature. It was about 6'2" with a thin, nonthreatening frame. Upon further inspection, I saw that the creature had eight tentacles which where equipped with suckers and smaller tendrils. The creature moved like a snail, slowly sliding along.
