I, Xiao Zhen, am a 17 year old high school student. My sister, Wenjun, is a girl who loves SM, and my sister and I both share the same hobby, and our mom sometimes joins us (but not often!). But lately, we’ve been feeling less and less excited about it, and we’ve been getting bored as we’ve been exchanging abuse with my sister and I. But there’s nothing we can do about it! But there was nothing we could do about it! Until one day last summer vacation…
(First day of summer vacation) My sister and I were hanging out in my sister’s room.
“Sis! We’ve been so bored lately! Is there anything new?” I asked my sister.
“It can’t be helped! I don’t know how I’m going to play it! And there are no new tricks.” Sister said.
“Well, can we get Mommy to play with us?” I asked.
“Yeah! But ‘last time’ didn’t mom say we were having too much monotonous fun?” Sis said.
“So can I give you guys some IDEA?”
“Mom?” My sister and I said.
“Mom! When did you get in here?” Sis asked.
“I’ve been listening for a long time!” Mom said.
“Mom, do you have any good ideas?” I asked.
“I don’t have any good ideas, but I do have a suggestion, and I wonder if you sisters would agree to it?”
Mom asked.
“Let’s hear it!” And my sister said in unison.
“OK, have you guys ever heard of a Japanese term called ‘female dog’? That’s what I read on the internet, and I think it’s a good way to play in Japan!” Mom said.
“I’ve never heard of it! But it seems like a lot of fun! ‘Female Dogs’, does it give us an idea of what it’s like to be a dog?” Sister said.
“It’s still my sister who’s smarter oh! That’s right! But this will make you live a very humiliating life, which can test your level of masochism, so you sisters think about it! Come to my room at 8:00 tonight and tell me the answer.” Mom said and walked out of the room.
“Do you want it, sis?” I asked.
“What about you?” Sister said.
“I don’t know yeah!” I said.
“Then we’ll talk about it tonight in Mommy’s room!” Sister said.
I heard a voice in my heart that said, “Say yes! Say yes!” Repeatedly in my mind… the masochistic feelings inside me were festering.
(7:55 p.m.)
I walked to the door of Mom’s room and I opened it gently, as if I was afraid of being discovered.
“Sis! You’re here already! Did you promise too?” I asked.
“Yeah! I’ve been thinking about it for a long time and decided I’d like to give it a try.” Sister, who was sitting in a chair, said, “Did you say yes too?” Sis asked.
“Yeah! I think I’m on the same page as you.” I said.
“You’re all here! Have you thought it all through?” Mom asked.
“We’ve all thought about it.” My sister and I replied in unison.
“Okay! Let’s go to the basement first then!” Mom said.
My sister and I walked into the basement with a sense of unease and a little excitement.
Beginning of conditioning.
“All right! Both of you take off all the clothes and pants you have on! Dogs don’t have clothes.” Mom said.
I took off my clothes and everything and I stood naked next to my sister who was doing the same.
“Alright! I’ll help you ‘pierce’ first!” Mom said.
“‘Piercing’?”
It turned out that mom had helped us put a small iron ring around our womanly nipples, which made our breasts look even sexier with the ring on.
“Next you get down.” Mom said.
My sister and I were on the floor and our asses felt much cooler, as if we were two slutty bitches on the floor.
“I’ll start by colonizing you and cleaning your anal opening.” Mom said.
Mom held a 300cc syringe in one hand and injected it into my anal opening first. A cool sensation came from my anal opening and I shook, as if my whole body was paralyzed.
Suddenly a feeling of wanting to poop went straight to my head, “Mom, can you stop for a second? I want to go to the bathroom so bad!” I said in agony.
Mom didn’t answer my question, I saw her hand holding the cork towards my anal opening and there was more cork in my anal opening. And the feeling of wanting to go to the bathroom but being blocked by the cork, a feeling of pain coupled with pleasure exploded through my body.
“No taking it down!” Mom said sternly.
After about 10 minutes.
“Come! Shin you crawl up behind your sister’s ass and swallow all your sister’s excrement.” Mom said.
“Yes!” I obediently crawled to the back of my sister’s buttocks and opened my mouth, and then my mother pulled out the cork that was in my sister’s anal opening. After about 5 seconds, the yellow liquid plus some good like mud poop instantly from my sister’s anus flowed out, and discharged excrement immediately rushed into my mouth, I also feel my sister’s these excrement still have residual warmth.
I suddenly felt another sensation, a thrill of eating poop, and I think I liked eating other people’s feces.
“Ah! Mom, I’m so ashamed! So humiliating that I let my sister eat my poop and it’s all for everyone to see.” Sister said.
“Who says only your sister eats your excrement! You crawl behind your sister’s little really and take after your sister.” Mom said.
My sister climbed up behind my ass, Mom pulled the cork, and as if my anus was liberated, all the excrement spurted out at the same time, and my sister seemed to be enjoying herself.
Mom helped us clear our anal opening with water, “Okay you guys go ahead and get your school summer uniforms from your room.” Mom said.
“Good.” My sister and I said.
As my sister and I walked, we thought back to the torture of folding just now, and an inexplicable feeling exited our hearts.
“Zen, what do you think mom wants us to do with the uniforms?” Sis asked.
“I don’t know! We’ll just take it anyway!” I said.
My sister and I grabbed our summer uniforms and walked down to the basement where we had just been.
“Mom, we brought it!”
Mom came out of the door of her room wearing… a sailor uniform from our school? And in her right hand, she was holding a box about 30 centimeters high.
“Put on just your socks and shoes first.” Mom said.
When my sister and I put on our leather shoes and saw each other, it was as if the two schoolgirls were completely naked, just wearing socks and leather shoes, and I had an indescribable feeling in my heart.
“Put these on before you put all your uniforms on.” Mom said.
Mom threw two collars to us, my sister and I put on the collars, I couldn’t help but be happy because it was about to start. Then my mom took a piece of iron smithing about 45 centimeters, and locked one end to my sister’s collar and one end to mine, with locks on both ends, so that my sister and I could not be separated.
“This iron refinement probably won’t be unlocked until the end of summer vacation, and as for the key, I’ll keep it!” Mom said.
Mom took out two pieces of twine and tied her sister’s hands behind her back, then tied her sister’s breasts, and then wrapped them around her bottom and tied a very large knot, and Mom pushed that knot into her sister’s cunt with her hand.
“Ah!” My sister yelped.
After tying my sister, mom did the same analogy, and mom pushed that knot into my pussy just as she did.
“Now I’ll help you put on your uniforms.” Mom said.
Once dressed, none of us could tell from our appearance that we were tied up, but our hands were tied behind our backs. We had our uniforms and skirts on, but we weren’t wearing panties. Mom took out two more pairs of leg irons from that box and locked them on for my sister and me. My hands and feet were restrained, and I was already feeling the pleasure of being abused in my mind, and the feeling of having my feet locked, my hands tied behind my back, and not having any difficult panties on made my lower body water with lust.
I had thought that was it, but I didn’t realize there was more. Mom took out two more pink like two oval eggs, there is a wire on the eggs, this wire is connected to a place like a controller, mom first pulled the knot out of my vagina, and then stuffed the pink egg into my vagina, and then turned on the switch.
The sound of “BUZZ… BUZZ…” scared me, and the sensation coming from my lower body made me feel as if I were about to ascend to heaven, and the sensation went straight to my head.
“Ah… mom… this is so… good! Ah… Mom…” both my sister and I screamed out.
“All right! The great work is done! These things you have on you will be on you for a long time.” Mom said.
Then mom led me and my sister to another room in the basement. There was a dog cage about 60 centimeters high and 200 centimeters long. Mom opened the door and my sister and I were pushed in by Mom, who put a big lock on the cage door and the key was left with Mom.
“To be like you, I live in a dog crate like you.” Mom said.
“But! We have just enough of this cage already, mom you might not be able to get in if you want to come back in.” Sister said.
“Who says I have to live with you guys?” Mom finished, pulling back the large black cloth next to her, which turned out to be a dog crate about a man high.
“And look at that.” Mom finished by lifting up the skirt of her uniform, which was actually tied with ropes just like ours, only without the pink eggs.
Then mom climbed into the steel cage as well, she locked herself in the lock and she slept in the cage herself.
My sister and I looked at each other in the cage, my sister gave me a kiss first and I gave her one, we were both happy to be ‘girl dogs’.
(Second day of summer vacation)
My sister and I were woken up in our cages.
“Breakfast.” Mom called to us.
Mom took two bowls for dogs and brought them to the cage while the bowls were the famous dog food X-way. For the first time I got to eat the dog food that I usually take to the dogs, and now it became my mom taking it to me, and I couldn’t tell you how I felt. Since both my sister and I had our hands tied, we both went down to lick it with our mouths, and when I took my first bite, the feeling in my heart was greater than the actual feeling.
After we finished eating, mom opened the dog cage and took my sister and I out, my sister and I squatted on the ground and looked at each other’s pussies. Mom took two 300cc syringes and pumped them into my anus, the sensation came immediately, the abdominal pain made me want to go to the toilet, and all the dog food I had just eaten was pooped out, spraying all over the floor.
At this point I saw my sister take the initiative to crawl behind my ass, she licked my asshole with that tongue of hers as if she was helping me clean it, and all the excrement on the floor, my sister ate it all into her mouth.
For the sake of what my sister just did, when my sister was done with the colonic I also volunteered to help her clean her asshole, I looked at my sister’s feces on the floor, there was yellow liquid, and some brown poop, I licked it with my tongue a few times first, then I ate it into my mouth one bite at a time without any consideration with my mouth.
10:00 a.m.
Mom told us to eat a little more food, but of course my sister and I had to eat dog food, and my sister and I only had one can before we couldn’t eat any more.
After we had eaten, my sister and I were taken to two other rooms which had two tables, full and short, and the tables had iron cuffs that could be fastened to the four legs. My sister and I were taken to the table, and my hands and feet were fastened around the table, and my whole body was just lying on the table, and I couldn’t move. Then my mother brought an iron frame with hooks on it, and then she brought two bottles of ‘drops’, which were more like glycerin for colonics than drops! Mom took two thin hoses and connected one end of the hose to the bottle of glycerin and one end to my asshole.
“This drip is for 1000 cc’s, you won’t be able to unlock your locks until it’s completely finished, and you can train your endurance in the meantime. As for me, I’ll leave to prepare for the next segment! Farewell! My dear daughters.”
When mom finished, she left the room without looking back, leaving my sister and I at the table to receive this painful torture, but both my sister and I were hot in the middle of it.
As time went by, the glycerin in my body gradually took effect, and my anus looked as if it was going to explode, but my anus was blocked by my mom’s cork, and I’m sure my sister was the same way, but I couldn’t move my limbs because I was bound by the iron handcuffs. I felt a lot of pain, but there wasn’t any unhappiness in my body, because I wanted it! I was transformed from a girl to a woman by the abuse of my mom and the torture device!
2:50 p.m.
“It should all be dripping, right?” Mom said as she opened the door and came in.
“Sure enough it has dripped, my daughters, do you still like it?” Mom said.
“Hmm! Your anal opening is much softer after my many days of colonic, it’s much more comfortable now, isn’t it?” Mom said as she rubbed my asshole.
Both my sister and I were speechless, as we were now completely drained after having just expelled all the fecal matter.
“By the way, I have a gift for you sisters! Look.” Mom said, from behind her back, she took out two dog tails, and the other end of the tails was a round head made of plastic, Mom gently inserted the tails into my ass, and as my ass wiggled, my tails wiggled along with it, and I just loved this gift.
“Thanks mom! We loved it!” My sister and I said.
18:00 (dinner time)
(Interlude of cousin’s visit)
Today my sister and I ate dry dog food, but I got precious pee from my sister, which was a little salty, but I drank it all up anyway.
Then mom took out two sets of clothes, one for me and one for my sister, and then undid all the restraints on our bodies. For me, mom gave me a pink suit, a pink skirt, and a pair of rather sexy panties, but before putting on the panties, she inserted a pink vibrator, and for my sister, she wore…
It was our school uniform, a black and white top sailor suit, and a pleated skirt that came down to our knees, and the panties were mine, which meant that Mom helped us change into each other’s costumes. What the hell was that going to do? My mind wondered.
“You must be wondering now why this is necessary. I will tell you all! We have guests coming today, your cousins and aunts, and they are waiting in the living room now, so let’s go up!” Mom said.
So it’s Auntie and Cousin Shuhuan who are here! I walked up the stairs to the living room step by step. I saw Auntie on the sofa, and where was Cousin?
“If it isn’t Wenjun and Xiaozhen! They’ve grown so big!” Auntie said.
“Auntie! Where is cousin? How come I don’t see her?” Sister asked.
“You mean Shuhuan! She’s in the restroom preparing something for you guys, and you’re getting a tune-up from your mom, right? It must be very comfortable!” Auntie said.
“Auntie, how did you know?” My sister and I asked curiously.
“How could I not know? I’ve already heard from your mom! You don’t have to be embarrassed, your cousin Shuhuan is too!” Auntie said.
“Cousin too? Is she under your tutelage too?” My sister and I asked.
“That’s right! That’s right! I…”
“Wenjun, Xiaozhen! You guys come to the restroom! Hurry up!” Mom suddenly interrupted Auntie’s conversation.
My sister and I walked towards the toilet, but to my great surprise, I saw that my cousin was in the toilet, she took off her panties and squatted on the floor, and there was a pink basin between her legs, while the excrement then fell into the basin. I suddenly felt happy in my heart because I knew what my sister and I were going to do.
My sister and I immediately climbed over and I licked Cousin Sukwon’s asshole first, then put my head down and ate my cousin’s excrement one bite at a time. After about 10 minutes, my sister and I finished everything in the basin and I wiped my mouth with toilet paper first.
It was a relief to learn from mom that it seemed like our cousin was a girl who liked SM as much as we did.
Third day of summer vacation (9:00 a.m.)
Mom took the clothes and gave them to us, “Here are my clothes for you sisters to wear.” Mom said.
My sister and I took over the clothes and realized that the skirt was so short that it looked like it was being worn by a national primary school student, and so was the top. I barely managed to put on my panties, but found that they were too small and constricted my entire lower body, making me so uncomfortable, and the skirt I put on even only covered half of my ass. Mom took another gag ball and stuffed it in my sister’s and my mouth, and as soon as it was stuffed, my saliva immediately flowed out. Mom also took twine and tied my sister and I up, then the other end of the rope was wrapped around the beam of the house, then my sister and I were hung up like this, because my body was taller than my sister’s, so all of my saliva flowed onto my sister’s body.
I’ve run out of ideas as of this writing, so I’d like to ask all my friends and seniors to give me advice or provide me with new names of torture devices, new story content, and characters to include so that I can continue writing.
Thank you!
