I froze, my body trembling at the thought of obeying her command. The bikini bottoms were so tiny I wasn’t even sure they were covering my pussy at all anymore. I typed back quickly, “I can’t, Caitlin. This is too much.”

Her reply came instantly: “Do it. I know you love being told what to do. It’s fun to switch off your brain, isn’t it?”

I felt a rush at her words. She was right, of course. The thrill of letting her guide me, of giving up control, made my skin tingle and my core ache. Slowly, I turned around, my back to the windows as I leaned forward.

The thin strip of fabric at my hips tugged against my skin as I bent over, and I felt the cool night air sweep over my wet lips, reminding me of how helpless and exposed I was. A shiver ran down my spine as I clenched my thighs, trying to fight the maddening sensation to run away and make myself cum. My hands gripped the railing for support as I glanced back over my shoulder.

“I’m doing it,” I typed, picking up my phone and typing with shaking fingers.

“Hold it there,” Caitlin replied. “Now sway your hips. Let them really see you.”

I did as she asked, swaying slightly, gyrating my fat pale ass against the railing. The tiny strip of fabric felt even smaller with every movement, slipping further between my cheeks and lips and making me feel utterly bare.

Looking back over my shoulder I noticed that one of the men in the group leaned forward, his drink forgotten in his hand. The married woman in the robe stepped fully into the light of her window now, her eyes locked on me as she leaned casually against the frame. My cheeks burned, but the forbidden thrill of being watched only heightened my fear, embarrassment, and arousal.

“People are definitely looking at me,” I typed, barely able to focus on the screen.

“Good,” Caitlin replied. “You’re giving them a great show, I'm sure. Kinda jealous lol.”

“Really?”

“Maybe. But we’re not done yet.”

I paused, my body trembling as I waited for her next command. The anticipation was intoxicating, each beat of silence between her messages making my heart race faster. Finally, the buzz came, her words making my stomach flip.

“Take off the bottoms.”

I stared at the screen, my heart pounding so loudly I could barely hear my own thoughts. I guess I expected it, wanted it even, but seeing it written still made my stomach drop.

I hesitated, my fingers trembling as I stared at Caitlin’s words. Take off the bottoms. The thin strip of fabric was all that remained between me and complete exposure. My heart pounded as I glanced back over my shoulder. The man across the way was still watching, his body leaning against the window frame now, his expression focused and intent. The woman in the robe hadn’t moved, her drink still in hand as she tilted her head slightly, as though waiting to see what I would do next.

“I can’t,” I typed, my breath shallow. My body was on fire, a mix of fear and arousal coursing through me, making my legs tremble.

“You can,” Caitlin shot back. “Don’t think. Just do it. I bet you’re super wet right now. Aren't you?”

I hesitated a moment. This would be a new line crossed. After a few seconds, I crossed it. “Yes, I am..”

“Perfect. Then stop pretending you’re not enjoying this.”

She wasn’t wrong. The cool air against my skin, the knowledge that people were watching, Caitlin’s control over me—it was all too much. My hand moved almost automatically to the strings at my hips, hesitating as I felt the delicate knot under my fingers.

“What if someone takes a picture or something?” I typed.

“So?” Caitlin replied. “You’re putting on a show, remember? You’re a slut now, remember? Now stop stalling. Be a good girl and take them off.”

Her words sent a shiver down my spine, and before I could stop myself, I tugged at the knot. The strings slipped loose, and the tiny fabric fell away, leaving me completely bare. The cool night air brushed against my wetness, making me gasp as I straightened slightly, still gripping the railing for balance.

“I did it,” I texted, my hands shaking, opening my legs slightly but too afraid to look back over my shoulder.

“Good girl,” Caitlin replied. “Now touch yourself. Show them how much you love it.”

My breath caught, my heart thundering in my chest as I stared at the screen.

My hand moved toward my pussy…
