My fondest memory of my late mother was the day she let me serve as her toilet.

I put this in the catagory of "gross" because most people would say it is but I don't find it that. I loved having my mom shit in my mouth. I was 15 years old and mom caught me sucking on the hashmarks of her dirty panties while jerking off. She yelled at me at first then got quiet and then ordered me to strip and lay down in the tub. Then to my amazement she took off her panties and told me to sniff them. I sniffed the part that was on her ass not the part that was on her pussy like most little perverts might. Not me. I wanted to inhale her shit smell. Then she lifted up her skirt to reveal her massive black pubic bush and squatted over my mouth and lowered her ass hair onto my mouth. She said one word "LICK!" I obeyed and did not stop until I had a huge fat putrid turd half way down my throat sticking out like an obscene big black cock. I sucked on it or a few minutes until my mom said "chew." I chewed. It was dryer than I expected. It took half an hour to manage to chew up and swallow about half of her turd. She spent the entire time squatted over my mouth low enough for her asshole hair to tickle my lips. The stench was overwhelming but inspired the hardest erection I'd ever had. I continued chewing slowly when mom re-positioned herself and peed between the turd and my open mouth. It dribbled its way down my throat making the turd easier to chew which also brought out the intense putrid flavor of the turd. Finally after about an hour of chewing and working it slowly down my throat with the aid of her bitter salty piss, I finished swallowing the last morsel of shit. Then Mom commanded "LICK!" She made me lick her clean. That took another fifteen minutes or so.

After completing my new duty as her human toilet she gave me permission to jerk off with my tongue up her ass.

From then on every morning I had toilet duty. I wanted to eat all her shit all the time and drink all her piss as well but Mom said I'd get sick if I did that. So I was limited to being her full time urinal and my tongue was now the only toilet paper she ever used but I only got to be her full toilet once a month.

On my 16th birthday mom had a surprise for me. My birthday was on a Monday. That Friday she said I was visiting her sister and that we would celebrate my 16th birthday there. My aunt was well off financially. I don't mean she was a billionaire but she probably was a millionaire. She lived in a mansion and had a Mercedes and a small yacht and a beach house so she was well off and she always gave the very best gifts.

So when Mom and I arrived she greeted us out front and led us inside. The moment I was in the house Aunt Joan loudly command "Strip!"

I looked at my mom and she shrugged her shoulders and said "if you want to be our toilet I suggest you strip.

I was naked in half a second. In keeping with the mood I thought it best to drop to my knees and bow my head. I saw that in a bondage video I once jerked off to. It was the right thing to do. Aunt Joan put a slave collar around my neck and led me by a leash down to her basement where I'd never been before. when I got down there she led me to a dark room. She turned on the lights and there sticking out of the wall was a black box that looked like a coffin on a short platform. She opened the lid and told me to get in head first. I did naked. I was shackled into place with rubber shackles. The entire compartment was lined in black rubber. There was a soft cushion under my head. The "coffin" was at a slight incline with a drain hole at my feet. There were holes in the sides for my legs to stick out of. She had me put my legs through though they were wrapped in the rubber lining. I felt restraints attached to my ankles and legs and thighs. Then I felt them lifted up. A bright light accompanied the sound of a door opening and I could see down between my legs as a rubber harness was attached to my balls causing them to protrude. Another rubber harness was put on my cock and that had a metal rod at the end that inserted about six inches into my pee hole. I later found out it was hollow. A butt plug was lubed and inserted up my ass. The door was closed leaving my legs up in the air and my ass in a position ready to be fucked if that was the plan. I heard the door to the room close and I was left alone with my excited and slightly scared thoughts.

A moment later a bright light exploded onto my face. After adjusting my eyes I realized I was looking up from the under side of a toilet seat the cover having been lifted to a vertical position. Aunt Joan showed my mom how to work some controls and my head was lifted up and down and the entire box shifted with me in it so my mouth would be in different positions under the toilet seat. Then the seat cover was lowered to within a quarter inch of my nose. The lights were shut off and the door was closed.

I have no idea how long I was there but some time later the light exploded onto my face again as the lid was opened and my mother very casually lowered her panties and lifted her skirt and sat down over my face. The controls re positioned my mouth to her pussy. In a second piss gushed into my gaping mouth. I swallowed as fast as I could but I missed some. I was given the command to lick so I licked her pee hole clean. When Mom was satisfied with my performance she dropped the toilet seat to within a quarter inch of my nose again leaving me to enjoy the intense flavor of her piss. Then I heard a loud flushing sound and water sprayed on my face. I could feel it flow down the sides of my naked body and drain down at my feet.

Some time later Aunt Joan needed to take a shit. My mouth was positioned under her ass. I didn't need to be told to open wide. Her shit was a bit softer and easier to eat than Mom's usually was. It also stunk far worse but she gave me ample piss to rinse her shit down with. I think it took me half an hour to eat her turd.

Mom took her turn shitting in her new toilet some time later but then many hours passed and I fell asleep.

I was woken up by another bright explosion of light over my face. A woman's ass that I never saw before descended onto my mouth. The control lifted my mouth tightly against her asshole and in a moment an explosion of diaria gushed down my throat. I thought I could handle anything but I almost puked it up until she followed it with a lot of piss.

Almost as soon as the mysterious woman left Mom came in to take her morning shit and that was followed by another different strange woman's asshole followed by Aunt Joan followed by yet another woman's asshole. A total of five women used my mouth as their only toilet repeatedly. Thankfully most of the visits were for pissing. I did get a huge amount of satisfaction serving as a full toilet eating all that shit and being treated as though I was nothing but a plumbing fixture to be used and if possible used up by a bunch of women with very active colons but there are physical limits to being a human toilet.

I had now way of telling the time. I could not tell you while it was happening if I'd been there an hour or a week. When you have few external stimulation you lose track of time easily. I guessed it was about a week I'd been there attempting to count the number of times the women were shitting down my throat. I'd also lost track of who was shitting in my mouth only caring about consuming as much as I could looking forward to each load rammed down my grateful throat. I lost track. All of a sudden there was a whole run of women shitting and pissing down my throat. One right after another more and more women none of whom I recognized took a shit down my throat. Periodically Aunt Joan tossed odd items down her new toilet that seemed like odd snacks. During the entire ordeal I almost continuously shit out of my ass and almost as if by magic every time I did I felt a cool burst of water spraying my asshole clean. the butt plug was hollow. I peed out of the rod in my dick. But I stopped paying attention to all that. Towards the end women I didn't know periodically poured pitchers of piss onto my face or down my throat but mostly I could not sallow but a fraction of the piss poured into the toilet I had become. If I had to guess I would have guessed that maybe towards the end twenty different women all shit down my throat. Aunt joan gave me something that pretty much kept me in a constant state of shitting diarrhea out my ass and I think my cock was a yellow fountain.

Finally the toilet seat opened up and as many women as could fit in the bathroom all crowded around the toilet and looked down and together they sang happy birthday. Not one had spoken a word since I had been shackled into my little prison. I was certain it was almost a week past my birthday but as it happens it was only about 3 in the afternoon on Monday, my birthday. Aunt Joan and Mom informed me that I would continue to be a toilet for the rest of the day and that many more friends would be over to use me and many of the women already there hadn't taken a turn yet. About a dozen more dumps were taken in my mouth and half a dozen one gallons pitchers of piss were poured onto my face and in my mouth. Finally my mom sat down to take the longest shit of her life. I'd swear it seemed like ten pounds of shit and two more gallons of piss were poured between her legs as I tried desperately to eat all her shit. With my eyes burning with shit and piss and my nose and ears filled with it and my whole body covered with all the piss and shit I couldn't quite swallow, I felt the door open up. The plug was pulled from my ass only to be replaced with a larger hollow plug that permitted the river of sewage to continue to flow out my ass. Then I felt a vibration and a tingling warm sensation deep up my ass. Clamps were applied to my balls and I felt a vibration and tingling there as well. Finally a larger diameter rod was inserted in my cock. I felt it all the way down into my bladder. I felt a stinging shocking sensation inside my pee hole. It wasn't strong enough to make me scream but it was sharp enough to hurt just enough to turn me on. Vibrating buzzing clamps were attached to my nipples. I later found out that all that were electrified and were shocking me at various intensities. But I paid little attention to any of that. I was desperately trying to chew and swallow all that turd my was shitting down my throat.

Then I felt the surge. I was half way through eating Mom's massive turd when I came. I felt like I was convulsing. My whole body shook. I thrashed about to the limits of my shackles and thought I was going to choke to death on all that shit and surprisingly I didn't care and the thought of choking to death on mom's shit while drowning in all that piss as I was cumming made me all the hornier and cum even harder.

Finally I was done cumming. I still had a third of the shit to finish eating. It took me an hour to complete that and drink as much piss as I could. A hose was turned on and I was sprayed clean with a warm gushing of water like I was being pissed on by an elephant. The door to the room opened and the coffin was opened up and the shackles undone and I was removed. A light turned on and that is when I noticed there was a shower in the corner of the room. I finished washing all the piss and shit off me. The smell of shit never left my hair. I didn't mind. I pulled my long hair over to my face and inhaled every time I wanted to smell shit.

I was led out of the basement and up the stairs where I found about 30 women, most I had never seen before all standing around applauding me. I was still naked and now 16 and I would have been humiliated were it not for the fact that I lad licked shit out of every one of their asses. There were no birthday gifts. I had eaten them all and no birthday cake, I'd eaten what served for birthday cake. They already had sung happy birthday to me.

I was sat down on a rubber upholstered chair in the middle of the room while all the women came up to me one at a time wishing me a personal happy birthday. Most told me things like how well I had served as a toilet. Many told me what a disgusting little toilet I was or how putrid I was or how I belonged flushed down the toilet to live in sewage in a septic tank and other words I think were meant to make me horny again. Only my mother, aunt and two women who later admitted to enjoy serving as toilets in my aunt's special bathroom kissed me. One of those two women stuck her tongue in my mouth and pronounced it delicious. She said she could still taste shit in my mouth and on my breath. We made out for about twenty minutes while the others chatted.

At that point aunt Joan presented me with the one and only changeable gift I got that year. she put a chastity cage on my cock and balls telling me I would get to come again on my 17th birthday after I spent an entire week servig as a toilet to her, my mom and a hundred of her closest friends.

She was true to her word though I was not able to keep up with all that shit. At 16 I had spent three and a half days serving at first just two women then five and finally thirty on my birthday. On my 17th birthday I had served as a human toilet already for 11 days for 100 women. Between them they produced over 500 gallons of piss alone in that time and no I could not even come close to swallowing all that piss. They had actually set up a urinal up stairs and had a pipe running down to me gushing a constant stream of piss onto my face. When I wasn't struggling to eat turds it simply flowed constantly on my face, over my eyes, into my ears and nostrils and especially into my clamped open mouth. The urine and shit that built up every few hours had to be flushed through the recently modified compartment to keep it fro all backing up. But I was pretty much constantly covered i piss and shit and yes in the end I had an all over diaper rash but I didn't care. In reality I probably consumed about ten loads of shit a day for those twelve days. Then on my birthday itself I had the butt plugged pulled out and I got ass fisted by my aunt. Mom had been practicing stretching me so aunt Joan's significantly thicker muscular arm was able to work it's way up my ass without making it bleed. I came with the sensation of her knuckles grinding against mey teenage prostate as mom took her final massive dump in my still hungry throat. That cum was even better.

Since then every year including this day I have celebrated by serving as a human toilet to a large group of women. I have been lucky not to ever have gotten sick but then I was conditioned from a fairly early age and I do still serve as my Mom's toilet every month for a weekend.
