As Jung-su listened to Tae-hoon and Il-ho's conversation, he clapped his hands and said, "Right, there was a video. Let's watch it."
Il-ho replied, "Wait a bit. I'll set it up so we can all watch it on the TV."
Il-ho and Tae-hoon got up and went into another room.
Meanwhile, Hye-na retrieved a small syringe from a storage cabinet in the living room corner. The syringe's nozzle seemed quite wide compared to its size.
Hye-na approached me with the syringe and said, "I'll teach you how to mastur.bate. Animals shouldn't mastur.bate like humans, right?"
I murmured, "Uh-huh..."
Hye-na sat down in front of me, exposing my vagina, and attached the syringe's nozzle to my clitoris. When she pulled the syringe's handle, my clitoris was sucked into the nozzle.
"This will make you erect even if you don't want to, and if you press it, the erect clitoris won't go back. How is it? You seem to like it so much that you don't need to be asked. It looks like it will become a habit. If you keep doing this, your clitoris will grow."
I pleaded, "Uh-huh... stop... don't make it bigger..."
Hye-na continued, "I'll make your clitoris so sensitive that even a slight touch will make you come."
As Hye-na repeatedly pulled and released the syringe, I felt an intense pleasure that made it hard to focus.
Just before I reached climax, Hye-na stopped and said, "If you want to go, move yourself."
I took the syringe from Hye-na and thought, "This foolish thing... doing it myself? My clitoris might grow... but I want to go, so I'll do it a bit more."
Already dominated by my desire, I continued to pull and release the syringe in front of Jung-su and Hye-na.
"Aah... aah... gaah!!"
I lightly ejaculated and trembled all over.
At that m0ment, the door opened, and Il-ho and Tae-hoon came out laughing.
Il-ho connected a USB to the TV and prepared everything. "Okay, it's ready!"
"Unnie, go to the side of the sofa and mastur.bate while watching the video as instructed."
I went to the side of the sofa with the syringe in hand.
"Let's watch it then~ haha!"
Everyone sat on the sofa, and Il-ho pressed the play button.
The video started with Tae-hoon carrying me into a room. In the video, I was acting foolishly, doing everything Tae-hoon wanted.
I whispered love to Tae-hoon, exposed all my openings, and seduced him by shaking my buttocks. I cleaned his penis with care, moved my hips on top of him without realizing my anal opening was wide open, and repeated embarra$$ing phrases. I also begged for kisses in his arms.
Il-ho, Hye-na, and even Jung-su couldn't help but laugh as they watched.
I felt immense shame and humiliation, continuing to mastur.bate with the syringe.
"Hahaha, unnie has such a taste? Wow, it looks like she'd give up her liver and gallbladder too!"
"I'm more embarra$$ed watching this... haha."
"Hahaha! Tae-hoon did all sorts of things...!"
"And this woman is mastur.bating while watching it... haha."
By the end of the video, I had climaxed lightly twice.
Il-ho called out, "Yu Han-na, come here."
I stood up in front of everyone, catching my breath.
"How does it feel watching it directly?"
"It... looks foolish... I was wrong..."
"Do you understand now how big your mistake was?"
"Yes... I'm just a toy for animals..."
Jung-su said, "Okay, from now on, we'll educate you to be suitable for a toilet. Bring that table and spread it out."
I brought a table from the kitchen and set it up as instructed.
"Get on it and bend over. Show your anus."
I climbed onto the table, bent over, and knelt, exposing my buttocks to Jung-su.
"Wow, it's still fine even after being penetrated like that yesterday... haha."
Jung-su rummaged through a storage cabinet and came back with something.
"From now on, your anal opening will never be closed."
I trembled in fear.
Jung-su forcefully inserted an object into my anus. The pain of my anal opening tearing was relieved as a large object slid in.
"It's an anal plug. It will be your friend from now on... haha."
I tried to push it out, but it wouldn't budge.
Jung-su explained, "Only we can remove this plug. Don't try to take it out by yourself. Hye-na will handle your bowel movements from now on, so if you need to defecate, call her and do it in front of her."
Hye-na complained, "Why do I have to do it again?! It's disgusting to watch... let's play rock-paper-scissors!"
Tae-hoon and Il-ho tried to placate Hye-na.
Jung-su touched my vagina, seemingly pondering something, and then said, "Let's do this later. Get up."
Hye-na intervened, "I'll do it from now on."
Jung-su replied, "Do it moderately and send her away. She might die... haha."
Hye-na brought a spool of thread and told Jung-su, "I'll take care of this."
Hye-na ordered me to bend over and expose my breasts. As I did, she twisted and pulled my nipples with her fingers.
"Wow, unnie's breasts are enviable... you're a piece of trash, though."
She suddenly twisted my nipples hard.
"This should be enough to make them erect."
Hye-na began wrapping thin thread around my nipples, tightening them so they wouldn't come undone.
I winced in pain as she wrapped them at least ten times.
After tying both nipples, Hye-na said, "Always wear these. Don't remove them even if they hurt... haha."
When Hye-na flicked my nipples with her fingers, it felt like they might fall off.
"Since the clitoris is too small to tie, take this home and make it more shameful. You can go now since you worked hard yesterday."
Hye-na handed me the syringe and said, "This syringe is a gift. Use it for mastur.bation from now on."
I felt relieved that I could finally go home and rest my exhausted body.
Hye-na went to the bathroom and brought out a blue bucket. "From now on, this is your toilet. You wouldn't think of using a real toilet like a human, would you? If you need to defecate, bring this bucket and do it in front of me. You can urinate here for now."
I took the bucket, which felt heavy with my waste from the previous day's enema.
"When you dispose of it, do it near your house. Soon, your neighborhood will be filled with the smell of your feces... haha."
I bowed in a dogeza position at the entrance and said, "Thank you for reminding me that I'm not human. I'll do my best as a toy for my masters. Thank you for managing my bowel movements, even though I'm worse than an animal toilet."
Jung-su told me to leave, and I finally exited the house.
I held the bucket with my feces in one hand and the syringe in the other, with an anal plug inserted.
My life, which I had lived diligently for 24 years, had become meaningless.
Dreaming of a beautiful and hopeful future like others was now a luxury.
From now on, my future would be one of degradation, offering my body foolishly and ruining myself. However, just imagining how hellish those days would be made my vagina wet.
I regained my composure, removed the dog collar from the utility pole, and put on my clothes.
On the way home, I worried that the bucket's lid might open on the bus.
As I walked, my tied nipples hurt whenever they brushed against my clothes.
When I arrived home, I emptied the bucket by pouring its contents far away.
As I saw my house, tears began to flow.
My sister was standing at the entrance when I opened the door.
"Sister! Where have you been? Why didn't you come home yesterday? I was worried. Why didn't you answer your phone?"
"I stayed overnight at a friend's place."
I couldn't respond to my sister's questions.
"Sister, did you cry? What's with your clothes?"
"I... I tripped on the way here. I'm fine."
I tried not to look at my sister and headed towards my room.
"What's with the blue bucket? Sister, look at me!"
When my sister grabbed my arm, my clothes pulled, and my nipples were rubbed painfully.
"Ahh... sorry. I'm really tired. Let's talk later."
I tried to remain calm despite the unexpected pain.
My sister looked startled by my cry and released my arm. I quickly entered my room and locked the door.
"Sister..."
My sister seemed to hesitate for a while before leaving.
I removed my dirty clothes and lay on the bed.
The bed was cozy, and I felt sleepy, but the foreign sensation in my anus didn't fade, and my tied nipples continued to ache.
I eventually fell asleep, unable to think of anything else due to the pain.
