EP.75 Promise 

At my brother's answer, Jung-su and Il-ho exchanged satisfied smiles as if everything was going according to plan, and Jung-su spoke in a more generous tone. 

"We're in this together now, right? Good. Then I'll let you have a go with her as a celebration. Hey, 4-ho." 

"Yes!" 

"When you're done licking, have sex with your brother once." 

"Ah... yes..." 

Though I felt guilty about my brother, I bowed my head and crawled toward him. 

Keeping my gaze lowered to avoid eye contact, I tried to unbutton his pants, but Jung-su called me with a stern voice. 

"Hey, get up." 

"Yes?" 

Sensing something was wrong, I tried to stand up nervously when Jung-su grabbed my right breast piercing and pulled me toward him. 

"Aaaah!!" 

I followed his pull to avoid the piercing from being torn out. 

Immediately after, he kicked me in the chest, causing me to fall backward. 

"Do you serve your customers this lazily too? Do it properly." 

"Cough, cough... I'm sorry. I'll do it again..." 

Finally understanding Jung-su's intention, I got up and stood in front of my brother. 

With obscene graffiti all over my body, I began to dance seductively. 

Thanks to having done this countless times while selling my body, I swayed my breasts and moved my hips rhythmically and vulgarly. 

It felt even more shameful to beg my own brother for sex, using formal speech and degrading myself. 

Making eye contact with him made it hard to breathe. 

"Please use my cheap 500 won pussy... Ahh... please allow me to serve you with my vagina~ Use me like a disposable onahole... haah..." 

"Hehe... Han-young, see what kind of woman your sister is?" 

"Uh-huh..." 

"What are you doing? Your sister wants to have sex with you. You need to answer her. Are you just going to keep staring? Hehe." 

"Ah... okay... I'll have sex with you..." 

My brother answered shyly in a barely audible voice, and I crawled between his legs and said: 

"Yes! Then... let me clean your penis first... chu..." 

I unbuttoned his pants and pulled down his underwear, revealing my brother's familiar penis, which I immediately took deep into my throat. 

I used the skills I had developed with customers, sucking his penis with mechanical efficiency. 

"Ugh!" 

The stimulation must have been too strong for him, as he ejaculated in my throat in less than 30 seconds. I wasn't surprised and sucked out every last drop. 

"What? You came already? Can you even have sex like that?" 

Jung-su taunted my brother disdainfully, while I lay back, pulling my legs up and exposing myself. 

"Please enjoy my ruined pussy..." 

Being young, my brother quickly recovered his erection, got off the sofa, and positioned himself at my entrance. 

Jung-su, Il-ho, and Hye-na just watched us siblings while snickering. 

I felt something enter me, but due to being so accustomed to sex, I wasn't excited at all by my brother's awkward thrusting and such ordinary intercourse. 

I focused on tightening my vagina to finish quickly, but since he had already ejaculated once and my tightness was weak, his movements showed no sign of stopping. 

Suddenly, my brother wrapped his hands around my neck and pressed down with all his strength while shouting: 

"You fucking bitch!!! You promised me!!! Ugh... You dog! You don't even know what hardships I went through!! gasp gasp And you just offer your pussy to other guys!!! This is too much!! When I wanted to do it, you always rejected me!! Damn it!!" 

It seemed like he had lost his rationality when faced with this psychologically difficult situation. 

'I'm sorry for being such a pathetic masochist... I should have resisted until the end... I've hurt you so much. I'm really sorry... sorry...' 

Even as I lost consciousness without any resistance, seeing my brother's tears falling broke my heart. 

"Guk... kek... sorry... kek..." 

With my last strength, I reached out to wipe away his tears before losing consciousness. 

Not long after regaining consciousness, I raised my upper body and looked around. Jung-su and Il-ho were sitting on the sofa. 

"You're awake? It took a while to calm your brother down." 

"Hehe~ This family is really messed up. And the parents don't even know what's happening to their children~" 

Soon after, I heard someone coming from the bathroom and turned to see Hye-na and my brother Han-young returning together. 

My brother's face was bright red, and he was naked from the waist down, covering his private parts with both hands while standing in the middle of the living room in front of Jung-su and Il-ho, who were sitting comfortably on the sofa. 

I looked back and forth between Hye-na and my brother, wondering if they had sex, when Jung-su spoke: 

"Yuhan-young. Remove your hands." 

When my brother silently removed his hands covering his penis, I saw that his pubic hair had been completely shaved, making his penis look particularly pitiful. 

"Bwahahaha!! Cute~ Hey, that kid is getting slightly erect!" 

"Good job. Now we just need to put that on, and we're done." 

Hye-na had taken out a small chastity device from the eco-bag I had brought and was approaching my brother. She squatted in front of him to put it on. 

My brother's penis became fully erect at Hye-na's touch. 

"Huhu... Han-young oppa. If you get erect like this, it's hard to put on~" 

"Ugh..." 

"Unnie, if you're awake, take the basic position in front of your brother and spread your hole." 

At Hye-na's command, I took the basic position facing my brother from just a step away and inserted my fingers to spread my vagina wide open. 

As my vagina widened, my narrowed urethra naturally released remaining urine, which dripped down. 

"Please look at my ruined loose pussy..." 

"Now, oppa. Quickly ejaculate once while looking at 4-ho~" 

At Hye-na's casual command as she squatted beside my brother with her chin resting on her hand, my brother began masturbating right there. 

"Unnie, push your pussy forward more and answer what I ask~" 

"Yes..." 

As I pushed my vagina forward, it felt so close that it was barely a handspan away from my brother's penis. 

"Unnie, do you remember what I told you in your room before? I said I would ruin your rosy life. I said I would make you so despicable that people would look at your body with contempt despite your pretty face, and turn you into a pathetic woman who finds happiness in that." 

"Yes... I remember..." 

"What do you think, oppa? Doesn't unnie look pathetic? Doesn't she look stupid? Would any normal person want to do this in front of their own brother? Isn't she contemptible?" 

My brother, stroking his penis, reluctantly answered Hye-na's persistent questions. 

"Ugh... she's contemptible... really pathetic." 

"Kyahahang~ Unnie, how does it feel? Are you happy?" 

"Haah... I'm happy... I'm a pathetic masochist who feels happy when despised..." 

Speaking while looking into my brother's eyes gave me an indescribable, sinful excitement. 

"Huhu~ You can look forward to becoming even more miserable in the future." 

'Huhk... even more than now?! Ugh... I want to masturbate too...' 

After hearing Hye-na's words, my heart fluttered with both fear and anticipation. 

"Ugh!!" 

Meanwhile, my brother's semen flew through the air and landed on my spread vagina, giving me a warm sensation. 

Click 

After my brother finished ejaculating, Hye-na, who had been watching, fiddled with the chastity device for a while before finally locking it and removing the key. 

"Heheh! Locked it~" 

"Ugh?! Ugh, what is this... quickly remove it... it's uncomfortable." 

Having completed her task, Hye-na hopped onto the sofa and snuggled up next to Jung-su. 

My brother's penis was no longer visible in his groin; only his swollen testicles could be seen. 

Where his penis had been, there was now just a hole for urinating. 

It seemed more painful than expected, as my brother was trying desperately to remove the chastity device with a clearly shocked expression. Watching this, Jung-su burst into laughter and said: 

"Hahaha!! It's useless. You won't be able to remove it except when having sex with your sister, so get used to it from now on. I promised that if you listen to us well, we'd let you do it with your sister. Hye-na and I will each keep one key. Don't worry about urinating; you can just pee as usual. 

4-ho." 

I was blankly watching my brother with sympathetic eyes when I heard Jung-su call me from behind. Startled, I didn't even think to undo my pose. I turned around awkwardly with my vagina still spread wide open, facing Jung-su while dripping my brother's semen, and answered: 

"Yes?!!"
