Irene and Yeri saw Seulgi's Instagram post of her in bikini outfit that they bought. They got jealous that she was showing her body (due to her recent bikini photos) to the world. When Seulgi came back, they had to remind her whose pet she always belongs.

Yeri was relaxing on her bedroom listening to her playlist when she heard loud banging on her door. Confused and startled, she get up and opened it. Irene was revealed to be the responsible, she was leaning at the doorframe with a blank face greeting her.
“What’s up, unnie?”
“Have you seen this?” Irene showed Yeti something from her phone. She took a look at it and saw a picture of their fellow member Seulgi in a bikini.
“N-no?”
“Look what that idiot just did.” Irene gritted her teeth. “We already told her, remember?”
“Yeah. I feel disappointed too.”
“Shall we do something about it?”
“What do you got in mind?”
Irene smirked in sinister afterwards as her only response. No more words needed, Yeri definitely must’ve understand what she’s trying to imply.
An hour later, Seulgi came home from her schedule today. Right as she entered the dorm, she saw Irene and Yeri at the living room, without realizing they’ve been waiting on her anticipatingly.
“Hey guys, you had dinner already?”
“Not yet.” Yeri replied lazily. Irene glanced at her with a serious demeanor. “But we already know what to eat for tonight.”
Seulgi nodded. “Oh okay. What is it? Can I have one too?”
“Oh don’t worry, baby. You don’t need to ask.” Irene chuckled and slapped her thighs as she rose from the couch. “Yeri, strip her out of her clothes.”
Yeri nodded while Seulgi was puzzled at what her unnie just said. “Wait what?”
It seems like tonight is just gonna be another night where she’ll be under their control again. Seulgi would love it to happen again but this time it wasn’t like that for now. She’s exhausted from work and she doesn’t have that stamina to go crazy with them on the bed.
As Yeri approaches, stood in front of her as she stared at her like a predator all locked in to its prey, she was about to remove her shirt but Seulgi hesitated. “Uhm, guys… can I ask a favor? Can we just do this some other time? I- I don’t feel like it tonight.”
Irene glared at her and came forward to shockingly slap Seulgi. “What the fuck did you just say? Yeri! Let her know what’s all this for.”
She took out her phone and opened Instagram. Seulgi saw her post on it and looked at them who are clearly irate. She has now understood why they are acting like this. “Wait, guys. I can explain. T-the manager s-saw it and told me t-to post it.”
“Your MALE manager?” Irene’s eyes went fiercer which effectively made Seulgi nervous.
“I-I gave her my phone while I was d-doing photoshoot.”
“What the hell are you thinking?!” Irene blew up.
“Didn’t we already have the permission to restrict our phones at them? How come he saw it?” Yeri added.
“So if he knew about that, then that means… he must’ve opened your gallery too.” Irene sideeyed Seulgi. “What if he already discovered those what we were doing-”
“I hid it somewhere, I promise!” Seulgi defended herself. “He does not know about it. I’m sure. I have the only access to it.”
Irene and Yeri sighed. They looked at Seulgi who seemed aware of her fate tonight. Might as well let her found out already. Irene shook her head and went behind Seulgi.
“Fine. That’s good, I guess. Because no one must know about us. However, I’m afraid you’re still not safe yet, darling.” Irene swept off some hair away from Seulgi’s cheeks.
“W-why?!” She asked anxiously.
“Did you forget who gave you that bikini and what was the purpose of it?” Irene whispered to her ear.
“For our eyes only. Yet, you let the manager see it… even worse, the entire world. It’s like, you have just flaunted the side of yours that we’ve created.” Yeri added.
“Exactly. It’s almost as no different that you have kept our secret of ours to anybody. You broke our promises, Seulgi. You broke our hearts.” Irene hold her shoulders as she leaned her face closer on Seulgi’s side.
“So tonight, the only fitting punishment for all of it is we are going to break you. And you will never say no when it comes to our cocks, right?”
As much as Seulgi wants to disagree, she can’t have worsen the situation. She nodded and accepted her defeat. “Yeri. Continue stripping her. We’ll put this bitch where she belongs.”
Yeri proceeded to undress Seulgi leaving her only in her black pair of bra and panties. Irene gripped her arm and dragged her aggressively onto the bedroom, throwing her at the mattress. “Yeri, go get the handcuffs.”
“Guys, I’m so sorry! I won’t do it again.” Seulgi pleaded. Irene raised her chin and inserted her thumb to let her suck it before she released. “If you mean it, endure all of these for us. Got it?” Seulgi lowered her head and nodded.
Yeri handed her the cuffs as she bounded Seulgi’s hands behind her back. Irene locked them off and there she sat with restriction of getting a touch of these two at all. Completely defenseless, Irene and Yeri liking how accurately Seulgi is looking when it comes to their presence.
“I’ve been ultimately loving this sight of yours being so awful and pathetic, but realizing you couldn’t fight as well to others just like what you are for us… it made us felt like we do not own you anymore.”
Irene grabbed two strap ons from their secret hideout on one of their closets. “That’s why we have no choice but to have you reminded who exactly you belong to. You ready, Yeri?”
“Always, unnie.”
“Great. I taught you well.” She kissed her on the lips before they began to wear the strap-ons featuring 7 and a half inch silicon girthy dominating cocks. Yeri pulls down Seulgi’s panties and stuffed it on her mouth.
“This is what they couldn’t give to you. The rightful balance of pain and pleasure, now let’s see whose power you still prefer to.”
Yeri sat on the pillow level of the bed and went underneath Seulgi’s body. Irene kneeled and lapped her pussy to get her wet first. Seulgi’s stifled moans on her panties as she felt how Irene’s wonderful tongue swirls around her cunt.
Satisfied enough, she let Yeri slowly bury her length on Seulgi’s slutty hole. Irene then lathered her cock with lube before going straight onto her asshole next, filling Seulgi up. They both began to move, fucking their submissive personal toy with all desire.
The two enjoyed watching Seulgi taking their cocks well done, her training paid off from constantly getting her holes molded into their sizes from the numerous times of sex they’ve shared since that one particular night where all this new kind of relationship began. And so they didn’t afraid to sped up the pace of thrusting on her stuffed holes.
Seulgi can feel definitely the length and girth of their strap ons stabbing her rear and core back and forth, rubbing those inner muscles and walls simultaneously so delicious. Her eyes are fluttering as it turns her on so much. Her arms gave up from support, colliding on top of Yeri’s chest which gave more angle on Irene to fuck her ass more.
She began to feel repeated spanking from behind, unbeknownst to how she turned her position more tantalizing on Irene’s view by how she looks stretched out. “How’s this, pet? Do they make you complete like we do? They may be doing their roles as your fans and your manager, but nothing comes close to us who knows you deep down in the bottom of your soul exactly who you are. Every part of you belongs to us! Do you hear us, pet?” Irene yelled as she pounded her harder, her skin slapping against her lap.
Loud stifled moans and whimpers can be heard from Seulgi, meaning she probably is answering that she understands it all. She pressed her face on Yeri’s breasts before she shivered as Irene saw how she squirted on her cock, reaching her climax.
It made the bed soaked wet and some to their feet. Irene slips out of her taut entrance proceeded by Yeri letting go of her small puddy, Seulgi was rolled to her back on the mattress, heavily breathing in exhaustion.
Yeri takes out the panty from her mouth and let her gasp, with some saliva dripping out from her lips. “We’re not done yet with you, pet. Once these are all done, make sure you’ll regret anything to happen again. Now fix up and be a good cock slave to us.”
Irene spread her legs and inserted back the strap on deep inside of Seulgi’s snatch. Yeri kneeled beside her face and requested to have her strap on get sucked. Being fucked again in double penetration, they assured to seal every holes of Seulgi and mark it as their property.
