Rainy Day with a Monster

*disclaimer this story does have pee / scat fantasy along anal play and other bodily fluid. Character is over 18. Readers discretion is advised. Also note that I had great help from neuroparenthetical. Thank you again!*

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.

While standing frozen in the rain due to fear, I forgot about the fact that I was completely naked! I started to slowly back away, but the creature continued towards me. I noticed a couple of its tentacles were outstretched and coming straight towards my feet. By this point, I had backed myself into a corner. I began to shake due to being wet and fear-stricken.

The first set of tentacles reached my feet. They slowly worked over my toes and up my legs. The little suckers making popping noises as they went along. It actually felt quite pleasant. The creature dispatched a second set. They reached my feet and wrapped around my ankles, holding my legs in place.

The first set of tentacles continued their journey between my thighs, over my dick and balls. They proceeded between my cheeks, across my stomach, over my chest, up and down my arms, and finally across my face. The little suckers stopped on my lips and smaller tendrils emerged, pushing their way through my sealed lips, making contact with my tongue, and then sliding down my throat.

I began to gag, but that didn't stop the creature. As soon as my mouth fully opened, one of the tentacles entered, causing me to really start heaving. I was about to vomit, but the tentacle stayed in place. My eyes began to water as I started puking. The tentacle finally retracted from my throat and both tentacles wrapped around my wrists. My arms were pinned to my side.

I was standing upright, unable to move. I pleaded with the creature to release me, but it became very apparent that it had other plans. As scared as I was, I didn't realize I had become aroused. Another tentacle traveled towards my dick and balls. It lightly tugged and massaged my member. Precum began to drip from my dick, and it landed on one of the tentacles.

This sent the creature into a frenzy. It began to vibrate and pulse. The tentacles near my cock sprouted smaller tendrils, and some of those went down my urethra. The tentacles already surrounding my limbs pushed me into a seated position. The fifth and sixth reached my thighs. They began to work their way up toward my ass cheeks. When they reached their destination, they parted my ass to expose my tight little rosebud.

The seventh tentacle exposed itself and began to tickle the entrance to my ass. It kept rubbing back and forth while secreting a jelly-like substance. All of the sudden it slowed to a stop. The eighth tentacle arose from the creature's body and went straight for my mouth. Once again it made its way down my throat, causing me to start gagging. Once the creature got me to start vomiting, it simultaneously plunged into my ass.

I tried not to focus on the pain. I tried to just relax, but I remembered that I hadn't shit all day, and now this large tentacle was inside of me. I felt so full! I tried to say tight. It was no use. The tentacle would enter and exit my tight ass until I was forced to relax and let whatever was going to happen, happen. I felt myself beginning to shit. The tentacle kept its pace, coaxing the shit out of my ass. When I finally stopped shitting the tentacle pushed even deeper into my ass.

I could feel it swell. It began pumping some type of liquid into me. I began to feel very full and bloated, to the point the fluid was coming out around the invader, but the creature kept going. I had nothing to hide anymore. The tentacle found my prostate. It noticed that every time it pushed on the sweet p-spot my dick would jump. It felt so good! It began working my prostate in earnest.

Each pump got me closer and closer to cumming. I had succumbed to the creature's torment. Its tentacles and tendrils worked me until I reached the peak. The tendrils in my urethra created such an out of body experience. I began to shoot ropes of. The creature caught all of it.

My body was exhausted. I had no more to give, but the creature started to pump my ass again - this time full of hard objects. I'd never felt so full in my life. The creature retracted its tentacle, but still held me in place. It continued to tug and massage my dick, causing me to cum again.

The creature picked me up and brought me to its face. My manhood was exposed. The creature opened its mouth and ran its long tongue all over my dick and ass. Its tongue pushed its way into my ass, where it wiggled around and teased my prostate. My head fell back with the feeling of bliss. I was slowly guided to its mouth, where its lips latched onto my asshole and a very strong suction ensued.

Every time an object was sucked out of my asshole it would cause my body to spasm. I lost count after four. The creature eventually placed me on the ground, face down, and disappeared.

It took a couple days for my body to recover from the trauma and pleasure it experienced that day, but I have been tempted to stand nude in the rain again and to coax the creature back out of hiding.
