Two girls moved into my neighborhood a few weeks ago. Yesterday they invited me to their house for some "fun". I arrive at their doorstep wearing my casual clothes. One of the girls open the door wearing the sexiest bikini I've ever seen. She lead me through the house and out to the backyard. The yard is surrounded in a 9 foot tall fence. I look to the left and see the other girl holding a rolled up slip and slide. She walks over the the center of the yard and rolls out the blue tarp. The other girls joins her at one end. They begin take off their bikinis until they're completely nude. They then crouch down over the slip and slide. I begin to wonder what they are doing. They start to breath really heavy. Then suddenly shit began spewing out of their assholes. They slowly shift across the side of the slip and slide until the entire slip and slide is covered in the juicy brown excrement. The smell reaches my nose and I almost throw up. I run to the door but it is locked. I rush over to the fence to try and climb over it but one of the girls grab me. I try to break free but the other girl runs over with a rope and ties my arms together. She then moves down to my legs and ties my ankles together too. They throw me to the ground. One begins to shout at me saying "How dare you try to escape!". One girl walked to the side of the house and pulls out a plastic lawn chair with a hole in the seat. The other girl drags me under the chair by my arms. She positions me so my face directly under the hole. One girls sits in the chair. I try to squirm away to prevent what's going to happen but the other girls holds me down. She grips my face and holds it directly facing the hole. The girl on the chair begin to breath heavy again. I watch as her anus begins to move as if her asshole is about to explode. She screams and liquid shit sprays all over my face. The smell of shit fills my nostrils. I start to get the feeling that I'm about the throw up, but that slowly fades away. The smell of shit also begins to fade. Shit continues to spray all over my face. Suddenly I begin to enjoy it. I open my mouth and it fills with her warm anus juice. The wonderful taste of shit fill hits my tongue. My dick becomes erect. The girl that was holding me down sees this and pulls of my pants and boxer briefs. She squats down over my dick and spreads her ass cheeks. She sits down, shoving my dick into her ass. I can feel her ass fill with the delicious frothy anus juice. She slowly pulls her butthole off my dick. I look to see my dick covered in the rich, oily anus juice. She bends over my dick and begins to suck on it like a popsicle. She fills her mouth with the warm, juicy shit and gulps it down. The two girls stand up. They can both see that I have learned to love the luscious shit juice. They untie me and allow me to stand. One of the girls walk over to me and whisper into my ear "You're ready". They then walk over to the slip and slide which is still covered in the lush shit juice. They stand at one end of the slip and slide and take several steps back. They hold each others hands and charge forward. They majestically dive onto the shit covered slip and slide. Their bodies slip across the moist slip and slide until they reach the end. They stand and allow me to see their shit covered bodies. I walk over to them and ask them if I can lick some of it off of them. They agree and allow me lick them clean of all of the tasty shit juice. After I'm done, one of them says "That's enough for today, come back some time". I then put my clothes back on and leave, planning to soon return.
