The afternoon sun streamed through the floor-to-ceiling windows of the penthouse, casting golden light across the Egyptian cotton sheets. I smoothed my hands over the silk duvet, adjusting the pillows for the third time. Everything had to be perfect tonight.

"Come on, Katherine," I whispered to myself, "you can do this."

My fingers trembled slightly as I reached for the small medical bottle on the nightstand. Dr. Chen had prescribed this specialized lubricant specifically for my condition—vaginismus, the diagnosis that had haunted me since adolescence. The cream-like substance contained both a dilator and localized anesthetic, designed to help my body relax enough for penetration without the searing pain I'd experienced before.

I uncapped the bottle, examining the clear gel inside. The instructions were clear: apply generously, wait fifteen minutes, then proceed with gentle pressure. Tonight would be different. Tonight would be normal.

"Just a few hours, and Xander will be here," I murmured, recapping the bottle and placing it prominently on the nightstand. "And I'll finally be able to give him what he deserves."

My reflection in the mirror showed a woman I barely recognized—flushed cheeks, nervous eyes, but determined. I touched my collarbone, a habit I'd developed whenever anxiety threatened to overwhelm me.

The intercom buzzed, startling me. "Ms. Foster, the catering staff is here," the doorman announced.

"Send them up," I replied, smoothing my dress.

When I opened the door, Brittany stood there with a champagne bucket, her smile too wide, too bright.

"Happy birthday to Xander!" she chirped, pushing past me into the penthouse. "I helped organize the catering since you were so busy with... other preparations."

Something in her tone made my skin prickle, but I pushed the feeling aside. Brittany had been Xander's best friend since college—his words, not mine. I'd learned to tolerate her for his sake.

"It's all set up," she said, lingering in the bedroom doorway. Her eyes flicked to the medical bottle on the nightstand, and a small smirk played at the corners of her mouth. "Everything looks... ready."

I felt heat rush to my face. Had she seen what it was? Did she know?

"I should go," she said, but made no move to leave. "Wouldn't want to intrude on your... special evening."

Finally, she left, but the door clicked shut behind her with an unsettling finality.

The elevator doors opened at seven sharp, revealing Xander. His tie hung loosely around his neck, and his eyes were slightly glazed—he'd started the celebration early.

"Happy birthday," I said softly, rising to kiss him.

"Katherine," he sighed against my mouth, his breath warm and smelling of expensive whiskey. "You've gone to all this trouble..."

"It's no trouble," I assured him, taking his jacket. "I want tonight to be perfect."

Brittany appeared again, as if summoned by some unspoken signal. "Rehabilitated the birthday boy!" she announced, throwing her arms around Xander's neck.

I watched them embrace, noting how her fingers lingered at the nape of his neck, how he didn't immediately pull away.

"Just stopped by to wish you both well," she said, her eyes meeting mine over his shoulder. "I know Katherine has some... special plans for you tonight."

Xander pulled back slightly, his brow furrowing. "What's that supposed to mean?"

"Oh, nothing," Brittany laughed, her voice light but edged with something sharper. "Just that some people have... complications."

I felt my stomach tighten. She was referring to my condition, I knew it.

"Brittany," Xander warned, but there was no real anger in his voice. "Not tonight."

She pouted dramatically before backing toward the door. "Fine, fine. I'm going. But remember what I said about pressure, Xander. Some people can't handle it."

After she left, Xander turned to me, his expression a mixture of irritation and something else—impatience?

"Sorry about that," he said, loosening his collar. "She's been weird lately."

"It's okay," I lied, though her words had stung more than I wanted to admit.

---

The bathroom was my sanctuary, steam rising from the drawn bath. I'd prepared everything—rose petals on the surface, candles flickering around the edges of the sink.

I stared at my reflection again, this time with determination hardening my features. Tonight would change everything. No more embarrassment, no more excuses.

"Xander deserves better," I told myself, reaching for the plush robe hanging nearby.

The bedroom was dim when I returned, lit only by the city lights streaming through the windows and the soft glow of candles I'd placed earlier.

I approached the nightstand, my heart pounding with anticipation and fear. The small medical bottle sat exactly where I'd left it, its contents promising freedom from pain, from shame.

My fingers closed around it, cool glass against my trembling skin. One step closer to normalcy. One step closer to being whole.

I didn't notice the slight difference in weight, the almost imperceptible variation in texture as I uncapped the bottle.

I didn't see Brittany's shadow move in the guest suite doorway, her eyes gleaming with triumph as she watched me prepare for what she knew would be my destruction.

The cool glass of the medical bottle pressed against my palm as I settled onto the edge of the bathtub. My heart hammered against my ribs, a mixture of anticipation and fear coursing through me. This was it—the moment that would finally make me whole in Xander's eyes.

I uncapped the bottle, the soft pop echoing in the tiled bathroom. The liquid inside looked slightly different than I remembered from my previous appointments—clearer somehow, with a subtle sheen that caught the candlelight. But my nerves were too frayed to question it.

"Just breathe, Katherine," I whispered, my fingers trembling as I dipped them into the cool gel.

The first touch against my skin felt wrong—too viscous, too clingy. I paused, frowning slightly, but pushed the thought aside. Dr. Chen had warned me that each formulation might feel slightly different.

I applied a generous amount to my most sensitive areas, the way I'd been instructed countless times before. The coolness was supposed to be immediate, followed by a gentle numbing sensation that would allow my body to relax enough for Xander.

But the coolness never came.

Instead, heat bloomed across my skin—not the warm flush of arousal, but an intense, searing burn that made my breath catch in my throat. It felt like I'd poured acid onto my most delicate tissues.

"What's happening?" I gasped, jerking my hand away.

The sensation intensified, spreading outward in waves of agony. When I looked down, I saw that the liquid had begun to change consistency, thickening and turning cloudy where it touched the moisture of my skin.

"No, no, no," I whimpered, panic rising as I realized something was terribly wrong.

I grabbed a nearby washcloth, desperate to wipe away the substance before it could do more damage. But as soon as the fabric touched my skin, a fresh wave of pain tore through me—the friction was accelerating the reaction.

"Oh God!" I cried out, dropping the cloth as my thighs began to stick together.

The realization hit me with horrifying clarity: this wasn't the medical lubricant. This was something else entirely—something that was literally bonding with my skin.

I tried to stand, but my legs wouldn't cooperate. The sticky substance had spread, creating a chemical burn that felt like my skin was being torn apart from the inside. I collapsed onto the bathroom floor, my screams echoing off the marble tiles.

"Xander!" I shrieked, my voice breaking with desperation. "Xander, help me!"

Footsteps thundered down the hallway, and the bathroom door swung open with such force that it slammed against the wall.

"Katherine?" Xander stood in the doorway, his expression not of concern but of irritation. "What the hell is going on?"

I looked up at him through tears of agony, my body convulsing with pain. "Something's wrong," I choked out. "It burns—it's burning me!"

His eyes flicked over me, taking in my collapsed form on the floor, but there was no compassion in his gaze—only annoyance.

"You're doing this now?" he said, running a hand through his hair. "On my birthday?"

"I'm not doing anything!" I sobbed, reaching toward him. "Please, help me up!"

Xander took a step backward, his jaw tightening. "This is exactly what Brittany warned me about. You're being dramatic again."

"Dramatic?" I gasped, disbelief momentarily overriding my pain. "Xander, I need to get to a hospital!"

"Stop it," he snapped, his voice rising. "You're ruining the whole vibe of tonight. We were finally going to—"

"I know what we were going to do!" I screamed, interrupting him as another wave of agony ripped through me. "But something is seriously wrong!"

He looked at me for a long moment, then shook his head in disgust. "I can't deal with this right now."

As he turned to leave, his eyes caught something on the counter—the empty bottle. For a split second, I thought he might realize what had happened, might understand that I wasn't faking my suffering.

Instead, he picked it up and hurled it against the wall. The glass shattered, fragments raining down around me as he stormed out, slamming the door behind him.

"Xander!" I screamed after him, but he was already walking away, his footsteps fading down the hallway.

I lay there on the cold tile floor, my body burning as if I'd been set aflame from within. Through the haze of pain, I heard the distant sound of laughter—Brittany's distinctive giggle floating through the apartment.

And in that moment, as my vision began to blur and darkness crept in at the edges, I realized that this had been no accident.

The bathroom door creaked open again, and I looked up through tears of agony to see Brittany leaning against the doorframe. Her silhouette was backlit by the hallway light, creating a sinister halo around her figure. Gone was the fake sweetness she'd worn like a mask earlier. Now her face was a canvas of cold satisfaction.

"Need some help?" she asked, her voice dripping with false concern as she stepped into the bathroom.

I tried to speak, but another wave of pain tore through me, turning my words into a strangled cry. The substance had spread further, creating a chemical burn that felt like molten metal against my skin.

"Oh, Katherine," Brittany sighed, crouching down beside me. "Did you really think I wouldn't notice your little medical condition?"

She held up a small bottle—identical to the one Xander had smashed, but this one was full. The label read "Industrial Strength Super Glue" in bold red letters.

"You see," she continued, twirling the bottle between her manicured fingers, "I've been watching you for months. Poor little rich girl with her embarrassing problem." Her lips curled into a cruel smile. "Did you really think I wouldn't find out what you kept seeing Dr. Chen for?"

Horror washed over me as realization dawned. "You... you switched them," I gasped.

Brittany's laugh was like ice picks in my skull. "Took me three tries to get the perfect timing. Had to make sure Xander was distracted just long enough." She leaned closer, her breath hot against my ear. "Industrial grade, Katherine. The kind that bonds skin permanently."

My mind reeled with the implications. This wasn't just a cruel prank or jealous sabotage—this was attempted murder.

"Why?" I managed to choke out.

"Because you don't deserve him," she hissed, her pretty features twisting with hatred. "You don't deserve any of this." She gestured around at the luxury surrounding us. "Your money, your privilege, your perfect life. I've worked so hard to get close to Xander, and you waltz in with your trust fund and your... problems."

I needed help. The panic button—my father had insisted I carry it after a string of kidnappings in our social circle last year. It was in my purse, just ten feet away.

"Xander!" I screamed, summoning what little strength I had left. "Help me!"

Brittany's eyes widened momentarily before narrowing with calculation. She darted into the hallway, her voice rising in alarm.

"Xander! She's faking! She's trying to get you in trouble!"

I heard his heavy footsteps approaching, then his face appeared in the doorway, flushed with anger.

"What the hell is going on?" he demanded.

"I need my purse," I gasped, reaching toward where it lay by the sink. "The panic button—please, Xander."

Brittany appeared behind him, her hand on his shoulder. "She's trying to get you arrested, Xander. For what? Not sleeping with her? Think about your future."

Something dark crossed his face—fear, perhaps, or simply the weakness that had always lurked beneath his charm.

"You're pathetic," he spat, striding across the bathroom.

For a moment, hope flared in my chest—until I realized he was heading for my purse, not to help me but to prevent me from calling for help.

"No!" I cried out as he grabbed the small device.

With one vicious stomp of his foot, he crushed the panic button beneath his heel. The plastic casing splintered, electronics spilling onto the marble floor.

"There," he said, brushing his hands together. "Problem solved."

Brittany's triumphant smile made my blood run cold.

The glue was setting completely now, my skin fusing in the contorted position I'd collapsed in. The pain was unbearable, radiating outward from my core in waves that made black spots dance before my eyes.

"Oh God," I moaned, feeling bile rise in my throat.

I vomited onto the floor beside me, but couldn't move to wipe my mouth or clean myself. The humiliation burned almost as much as the chemical reaction still taking place on my skin.

"Look at you," Brittany whispered, kneeling beside me again. "The perfect Foster heiress, covered in vomit, glued to her own bathroom floor."

She reached over and picked up my phone from the counter, dangling it just out of reach.

"Your daddy's security team can't help you now," she said, her voice almost gentle as she slid the phone across the floor and into the far corner of the bathroom.

I watched helplessly as my last connection to the outside world skidded away, leaving me alone with my tormentors.

The room began to spin around me as shock set in. Through the haze of pain, I heard Brittany's voice as if from underwater.

"She'll die here, Xander. Infection, shock, whatever. And then I'll take her place. Her money, her connections..." She paused, her voice dropping to a whisper. "Her boyfriend."

Darkness crept in at the edges of my vision as I realized with horrifying clarity: this wasn't just an attack—it was an execution.
