Flexible Steel Catheter Penis Plug

Benjamin's cock twitched helplessly against the tight cage as Angela circled the examination table, her white nurse's uniform pristine despite the thorough "examination" she'd been conducting. Red welts from her riding crop decorated his thighs, and the large plug stretching his ass made every movement a reminder of her complete control.

"Everything looks responsive so far," Angela murmured, making notes on her clipboard while Benjamin lay naked and restrained. His colleagues at the university library would never recognize the composed literature professor now—spread eagle and completely at his coworker's mercy in her private dungeon.

"But I have one final test to complete your examination." Angela set down her crop and opened a sterile medical kit, withdrawing a gleaming steel and rubber device that made Benjamin's breath catch. The flexible catheter caught the overhead light, its hollow design both beautiful and terrifying.

"This will measure your internal sensitivity," she explained with clinical detachment, though her eyes blazed with sadistic pleasure. She unlocked his cage with practiced efficiency, his cock springing free and already leaking with desperate arousal.

Angela's gloved fingers wrapped around his shaft, holding him steady as she positioned the steel tip at his opening. "Stay very still," she commanded, beginning to work the flexible probe deeper into his urethra.

Benjamin's back arched as intense sensations flooded through him—part pleasure, part burning pressure that had him gasping against his restraints. The rubber catheter slid deeper, the steel core providing just enough rigidity to navigate his internal passages while remaining flexible enough to follow every curve.

"Excellent response," Angela noted, watching his face contort with the overwhelming mixture of pleasure and discomfort. She twisted the device slightly, the hollow design allowing her to feel every pulse and throb of his arousal from the inside.

When she reached behind him to manipulate the plug in his ass, Benjamin nearly screamed. The dual stimulation—steel pressing against sensitive nerves in his cock while the plug massaged his prostate—created fireworks behind his eyelids.

"The examination is progressing beautifully," Angela purred, beginning to slowly withdraw and reinsert the catheter. Each movement sent lightning through his entire body, his cock weeping around the steel intrusion while his ass clenched desperately around the plug.

Benjamin's vision blurred as she established a rhythm, the flexible probe stroking places he'd never imagined could feel such intense sensation. His professional composure had completely shattered, leaving only raw need and the exquisite torment of Angela's thorough examination.
