I went to the pet store and bought three lucky gerbils, a whole set up for them. I took them home, stripped down, lubed up my ass then put the first brave gerbil into a condom. I looked him in the eyes and I could tell he was just as excited but nervous as I was. Then I shoved him inside me and out of instinct due to being squished in my tight little asshole the gerbil tried to burrow to safety which felt AMAZING. I bent over and moaned uncontrollably as the gerbil flailed and burrowed trying to save his life. Unfortunately it was in vain. After a couple minutes he stopped moving. The first brave gerbil on my sexual journey had died. My legs still shaking from pleasure I pulled him out of my ass and out of the condom. I looked at his lifeless body and he looked so peaceful it almost brought a tear to my eye. I threw him in the trash can then grabbed another condom and another gerbil. The second gerbil was quickly inside me and thrashed just as violently as the first. My legs buckled, my small flaccid penis started leaking. I laid on the bed, my legs shaking as I jerked my tiny penis as hard as I could. Unfortunately this one died quicker. A failure. I cast it into the trash and got the biggest gerbil ready. I swear he winked at me. It was hard to get him in but he started burrowing and thrashing directly on my prostate. I screamed in pleasure and came everywhere as that fat gerbil flailed helplessly in my asshole. My orgasm was so intense I lost control of my bowels and shit everywhere. As the diarrhea sprayed from me like a chocolate fountain the final dead gerbil plopped out of my ass and onto the bed. I laid there panting watching the mixture of shit and cum soak into the bed. Then I got up, cleaned up and got dressed, my legs still shaking. A truly unforgettable experience. I need more gerbils.
