THE PERFORMANCE

CASSY

Sienna's office is in Tribeca, in a building that's made of glass. The car ride over is torture. Not because of traffic or the silence, but because I can feel the vibrator nestled against me. Silent now, but there… a constant reminder that at any moment, with the press of a button, Sienna can make me lose control in front of anyone.

And she will. I know she will.

I keep my eyes on the window, watching the city slide by. People rushing to work, living their normal lives.

"Nervous?" Sienna asks without looking up from her phone.

"No, Ma'am."

"Liar." But she sounds pleased.

The car pulls up to a sleek building with "VALE TECHNOLOGIES" etched in steel letters above the entrance. People in expensive suits stream in and out. This is her empire, her kingdom built on hatred and brilliance in equal measure.

The driver opens Sienna's door first. She steps out with grace, already pulling on her CEO persona like armor. Then my door opens and I step out onto the sidewalk, and several curious people glance our way. Assessing me and wondering who I am.

Sienna doesn't acknowledge me at all. She just starts walking toward the entrance, and I follow like a shadow.

The lobby is all marble and chrome. Modern art on the walls. A receptionist who looks like she stepped out of a fashion magazine greets Sienna with a bright smile.

"Good morning, Miss Vale. Your nine o'clock is already in Conference Room A."

"Thank you, Mika." Sienna's voice is professional, warm even. Nothing like the cold command she uses with me.

We walk to the elevator. People nod to Sienna as we pass and she nods back, every inch the successful CEO. No one questions why I'm here. Maybe they're used to seeing her with women or they don't just care.

The elevator is crowded. Sienna stands in front, I stand slightly behind her, which is professional and appropriate. Then her hand slips into her pocket.

Oh no…

The vibrator comes to life. It's low and steady. My breath catches and I freeze. Every muscle in my body goes rigid as I fight not to react, not to make a sound. I wouldn't let anyone in this elevator know what's happening.

Sienna doesn't look at me. She's scrolling through her phone like nothing is happening but I see the slight curve of her lips. She's enjoying this.

The vibration continues building. My face is burning and I can feel sweat beading at my hairline. My thighs clench together involuntarily.

The elevator stops and people get off, more people get on. A man in a gray suit smiles at me. "Morning."

I can't speak. If I open my mouth, I'll moan. Sienna glances at me, then she raises an eyebrow.

Right… I'm being rude. I'm supposed to respond. "M-morning," I manage. My voice sounds strangled.

Then the vibrator intensifies and I nearly collapse. My hand shoots out, grabs the elevator railing. The man looks concerned.

"You okay?"

"She's fine," Sienna says smoothly. "Just a bit under the weather. Aren't you, darling?"

Darling… The endearment is poison-sweet.

"Yes," I gasp. "I'm fine."

The elevator reaches the top floor. Everyone files out. I can barely walk. My legs are shaking… oh god I'm so close….

The vibration stops. I sag against the elevator wall, gasping.

Sienna turns back, still holding the elevator door. Her expression is innocuous. Concerned, even.

"Are you coming? I have a meeting."

I hate her. God, I hate her so much.

I force myself to follow her down a hallway lined with offices, glass walls showing busy people at work, building her empire.

"Conference Room A is here," she says, stopping at a door. "You'll sit in the corner. You will not speak or make eye contact with anyone. You will simply... exist. Understood?"

"Yes, Ma'am."

"Good girl."

She opens the door.

---

Conference Room A is enormous. A table that seats twenty. Floor-to-ceiling windows with a view of the Hudson River. And seated around the table are five people in expensive suits, all looking at Sienna with varying degrees of deference and fear.

"Gentlemen, Ms. Park," Sienna greets them. "Thank you for your patience."

"Of course, Miss Vale," says a man who must be in his sixties. "We're eager to discuss the merger."

Sienna gestures to a chair in the corner. "Cassy, sit there."

Every eye in the room turns to me as I walk to the chair. I sit and keep my eyes down.

"Don't mind her," Sienna says casually, taking her seat at the head of the table. "Now, let's begin. I've reviewed your proposal, and frankly, I'm not impressed..."

The meeting starts. They're discussing a merger, Vale Technologies acquiring some smaller company for an amount of money that makes my head spin. Hundreds of millions of dollars being discussed like pocket change.

Sienna is brilliant, ruthless and she tears apart their proposal point by point, forcing them to justify every number, every projection. They scramble to keep up with her.

And I sit in the corner, overlooked like I don’t matter. Ten minutes in, I feel the vibrator pulse. Once. Twice, a warning.

I glance at Sienna. She's looking at the man across from her, listening to him stammer through an explanation of projected revenue, while her hand is in her pocket.

The vibration starts again, low and teasing. My hands grip the arms of the chair. I try to keep my face neutral. Just keep breathing.

"That's an interesting perspective, Mr. Wilson," Sienna says. "But your numbers don't account for market volatility. Try again."

The vibration increases. I bite the inside of my cheek, hard. The pain helps keep me grounded. But the pressure between my legs keeps building. The heat is spreading through my body.

Not here. Please… not here.

Sienna laughs at something Ms. Park says. The sound is genuine, warm. She's completely at ease while I'm falling apart six feet away.

The vibration pulses- on, off, on, off. It's worse than constant. I can't predict it or prepare myself.

"I think we need to revisit the timeline," Sienna says, flipping through papers. "Three months is unrealistic. I'm thinking… six."

"Six months would impact our Q4 projections," Mr. Wilson protests.

"Then adjust your projections."

Her hand moves in her pocket. The vibration becomes constant and strong. My vision blurs. I'm gripping the chair so hard my knuckles are white. I can feel it building… that point of no return, that moment where my body is going to betray me whether I want it to or not.

I can't. Not here. Not in front of these people. I look at Sienna, silently begging her. She meets my eyes across the room, holds my gaze and smiles.

The vibration intensifies, and I cum. Right there in the corner of Conference Room A, while five executives discuss merger terms, I cum so hard I see stars. My whole body goes rigid. I bite down on my lip until I taste blood, trapping the moan that wants to escape.

Wave after wave of pleasure crashes through me. It was devastating, humiliating and… Perfect.

The vibration doesn't stop. She's drawing it out to the last. Making sure I feel every agonizing second. When it finally stops, I'm boneless, and sweating. My face is flushed, my breathing ragged, and no one noticed.

They're all still focused on Sienna, on the merger, on the millions of dollars changing hands. No one saw me break, except her.

Sienna stands. "I think we have a framework. My lawyers will draw up the revised terms. Expect them by the end of the week."

Everyone stands, shake hands and thanks her for her time.

"Ms. Park, do you have a moment?" Sienna asks. "I'd like to discuss the Asian market expansion privately."

"Of course."

The men left, while Ms. Park, a woman in her forties with perfect posture and a Chanel suit stays.

"Cassy," Sienna says. "Come here."

My legs barely work, my knees are wobbly but I manage to walk to the table.

"This is Cassy Beaumont," Sienna says to Ms. Park. "My new... personal assistant."

Personal assistant… the lie is so smooth.

Ms. Park's eyes rake over me, assessing me. She's sharp, I can see it in the way she takes in the expensive dress, the collar just barely visible under the neckline, and my flushed face.

She knows.

"Pleasure," she says neutrally.

"Likewise," I manage.

"Cassy is learning the ropes," Sienna continues. "I'm training her personally. She's very... eager to please. Aren't you?"

Her hand slides into her pocket again.

No. No, she wouldn't-

The vibrator pulses, once. My whole body jerks. Ms. Park's eyebrow raises.

"Yes, Ma'am," I whisper. "Very eager."

"Good." Sienna turns back to Ms. Park. "Now, about Tokyo. I'm thinking we should…"

She launches into business talk. Market shares, expansion strategies. All while her hand stays in her pocket, occasionally pressing that button, making me gasp and tremble while Ms. Park pretends not to notice.

This is the game, the humiliation. This is Sienna showing me and anyone perceptive enough to see that I'm completely hers.

When Ms. Park finally leaves twenty minutes later, I'm wrecked. I've cum twice more, once during a discussion of profit margins, once while Sienna was laughing at some industry joke.

The door closes behind Ms. Park, and we're alone.

Sienna turns to look at me with those dark, unreadable eyes.

"How do you feel?" she asks.

"I hate you," I say. My voice is hoarse.

"I know." She walks toward me. "But that wasn't what I asked. How do you feel?"

"Humiliated."

"And?"

I don't want to give her the satisfaction by saying it, but she's waiting. And I'm too exhausted to lie.

"Turned on," I whisper. "I feel so… horny."

"Good." She's right in front of me now. Close enough that I can smell her perfume. "Because that's the point, Cassy. I'm not just punishing you. I'm training you."

Her hand cups my face. The gesture is almost tender.

"I'm training your body to respond to me. To crave me, and need me. Right now, you hate it. You hate yourself for feeling good. But eventually..."

She leans in, her lips brushing my ear.

"Eventually, you're going to beg me for this. You're going to NEED me to make you feel this way. And when that happens, when you're so broken that you can't imagine pleasure without me… that's when I'll know I've won."

She pulls back, smooths down my dress where it's rumpled.

"Now go to the bathroom. Clean yourself up. We have lunch in thirty minutes with a potential investor. And Cassy?"

I look at her.

"The vibrator stays in."
