The sheet of paper covering the padded exam table crunches loudly when Tony squirms. Stephen, standing over him in scrubs and a lab coat, smiles reassuringly. “There’s no need to be nervous, Mr. Stark. All I’m going to do is evaluate your degree of sensitivity.”
Tony watches, mouth dry, as Stephen pulls on a pair of latex gloves with a snap. “You can’t just take my word for it, doctor?” he asks as Stephen coats one hand in lubrication.
“I’m afraid not,” Stephen says. “I believe you, of course, but a patient’s experience of frequent, involuntary, and intense erections is subjective by nature; you only have your own penis to evaluate. I can be more objective.” He pauses and Tony sighs and nods. “I’ll begin with penile stimulation.”
Stephen wraps his lubricated, gloved hand around Tony’s dick. The touch is clinical, not sensual, which only makes Tony harden faster. He stares up at Stephen in his scrubs with his calm, professional demeanor and gets hard so fast it kind of hurts.
“That is a rapid reaction,” Stephen observes. He gives Tony’s cock one firm pump with his hand and Tony cries out, hips bucking upwards. Stephen lets go then and waits until Tony’s caught his breath before going on. “You were right to be concerned, Mr. Stark. This is a severe case. You need immediate treatment.”
Tony’s heart beats faster. “What kind of treatment?”
Stephen turns away, stripping off the soiled glove and replacing it before wheeling a steel tray over next to Tony. Arranged on the tray are a series of long, straight steel rods of increasing length and thickness, each with a loop on top. “These are urethral sounds,” Stephen says calmly, ignoring the dark, rigid erection that Tony is still sporting. “I’ll insert one or more of them into your penis until prostate stimulation is achieved. After removal, your control should be significantly improved, although several treatments may be necessary before full control is achieved.”
The sounds look far too large to go where Stephen is suggesting. “Will it hurt?”
“Not at all,” Stephen assures him.
Tony licks his lips. “All right, doctor. Let’s do it.”
“Excellent.” Stephen carefully lubricates the smallest sound and then takes Tony’s cock in hand again. Tony cries out, hips jerking. “Hold still, Mr. Stark.” Tony nods quickly and watches with wide eyes as Stephen places the tip of the sound inside Tony’s cock, holding both perfectly straight. He eases his grip on the sound and lets gravity pull it slowly, steadily into Tony’s cock.
Tony gasps, though he doesn’t move. There’s no feeling like it. The sense of invasion, the tingling of nerves that have never been touched like this. It feels like his cock is pounding in time with his heart.
Stephen hums, sounding disapproving. Tony glances down to see his dick has swallowed the entire rod. “You need considerably more than that,” Stephen says. He grips the sound and pulls it firmly out of Tony. The withdrawal, so much faster than insertion, makes Tony shout, his eyes rolling back in his head. When he comes back to himself, Stephen is waiting patiently, holding a sound that has to be twice as thick as the first. “Are you ready, Mr. Stark?”
“Yeah,” Tony says hoarsely.
The second, much thicker sound slides into Tony’s cock faster than the first. Heavier, Tony registers, trying not to whimper. He fails, tiny, sharp, chokes noises slipping out of him. God, being stroked on the inside is intense, and Stephen’s hand is still holding his dick firmly, providing an odd, wonderful counter pressure on the outside.
When it’s fully embedded, Stephen takes hold of the ring and twists. Tony moans helplessly, then cries out when Stephen pulls it out perhaps an inch and then lets it slide back into Tony’s cock. “Still not enough,” Stephen says, tapping the sound lightly. Tony makes a choked noise. Stephen catches his gaze.
“Whatever you say, doctor,” Tony manages.
“Excellent.” Stephen withdraws the sound and Tony sobs. The slide of the surgical steel leaving his cock almost feels like coming.
The last sound is huge. Tony can’t take his eyes off of it, watching breathlessly as Stephen positions it above his cock. He feels it the moment the tip slides inside him. God, it actually feels like it’s stretching him. Tony lets his head thump back onto the exam bed, eyes sliding closed as tiny huffs of breath escape him with each new inch of steel that slides into his cock. It slides deeper and deeper and then it presses against something new, deep inside him, and a bolt of pleasure shoots through Tony. He cries out, shouts sliding up higher and sharper when Stephen pulls the sound out a bit and then lets it slide back, sending the same shock through Tony, and again.
Tears are streaming from Tony’s eyes and he can’t think, it’s so intense. Maybe Stephen warns him, or maybe he doesn’t. Tony wouldn’t know either way. All he knows is that suddenly the sound is pulling out of him and it feels like it’s pulling his climax along with it. Tony wails when he comes, semen all but spurting around the sound, it follows the withdrawal so quickly. Stephen gives his cock a few firm strokes, helping milk Tony’s orgasm out of him.
Panting, Tony looks up at Stephen, still pristine in his scrubs and gloves. He smiles down at Tony. “Well done, Mr. Stark,” he says warmly. “Shall I schedule you for a follow up?”
Tony shivers. “Yes, thank you, doctor.”
