Silicone Urethral Sound

The airplane bathroom felt impossibly cramped as I locked the door behind me, my phone buzzing with another message from Kathleen. Three months of long-distance had been torture, but her latest package had arrived just before my flight with explicit instructions: "Open at 30,000 feet."

My hands trembled as I unwrapped the black silicone device, reading her note: "You've been such a good boy with the cage and taking my strap-on, but I know you're getting restless. Time to explore somewhere new."

The flexible rod felt warm in my palm, its ribbed surface designed for sensations I'd only fantasized about. The pull ring at the base caught the harsh bathroom light as I examined what Kathleen had chosen for me.

"Are you opening it now?" Her text appeared as if she knew exactly when I'd work up the courage.

"Yes, Mistress," I typed back, my cock already hardening at the thought of what she wanted me to do.

"Good. Lube up and start slow. I want to know exactly how it feels when something penetrates your cock for the first time."

My breath caught. We'd pushed boundaries before, but this was uncharted territory. I applied the packet of lube she'd included, coating the silicone thoroughly before positioning the tapered tip at my opening.

The first touch sent electricity through my entire shaft. The material was softer than I'd expected, yielding enough to follow my body's natural curves as I worked it deeper. Each ridge created a new sensation, my urethra stretching in ways that made my knees weak.

"Fuck," I whispered, gripping the tiny sink for support as the device slid further inside. The feeling was indescribable—not quite pleasure, not quite pain, but something entirely new that had my whole body trembling.

My phone buzzed again. "How deep?"

"Maybe two inches," I managed to type with shaking fingers.

"More. I want you to feel completely filled."

I twisted the ring like she'd taught me with other toys, and the ribbed surface created friction that made my vision blur. The sensations radiated outward from my cock, each movement sending waves of intensity through my groin.

"I can feel everything," I texted her, barely able to form coherent thoughts. "It's so intense, Mistress."

"That's my good boy. Now you understand why I chose this for you. Something completely new to keep you interested."

The plane hit turbulence, and the subtle movement sent the device shifting inside me, drawing a strangled moan from my throat. Kathleen had found the perfect way to remind me that even thousands of miles apart, she could still reach places no one else ever had.
