The doctor's office called and said they could fit me in for my physical that day. I thought nothing of it until the nurse told me to strip and that the doctor would be in to see me in a moment. I was locked in a chastity device.

I was a chastity devotee, loved wearing cock-locking toys, loved being forced to wear them, and in between relationships, as I was then, I hired an on-line keyholder to administer my chastity. I had an emergency key, but it was at home. I was so used to wearing the chastity device, suffering the pain of denied erections, that I'd left the house without even thinking.

"Oh fuck," I whispered, panicking.

Maybe I could reschedule. But I needed the physical to start the new job. The receptionist had moved things around to get me in. I'd look like a total dick if I left. A total limp dick. On the other hand, what would the doctor say? Would she write in her permanent record that I liked penis torture?

I grabbed my coat and was determined to just deal with the fallout of cancelling when Dr. Colleen opened the door to the room.

"Not undressed yet, Mr. Roberts?" she asked.

Dr. Colleen was one of the new doctors at the practice, the only one who could fit me in. She was just out of med school, petite, pretty with long dark hair. She was wearing a skirt over nylons and a blouse that showed off her perky breasts. Her doctor's coat hung open.

"Um," I said. My face burned and I knew I was beet red.

"You're not embarrassed, are you?" she asked. "Really, this is totally professional."

"I... I... forgot something that I should have done...."

"This won't take long," Dr. Colleen said. "I understand this is for a new job."

"Yes," I said.

"I understand you can be a little nervous about a strange woman seeing you naked, but I promise you it's no big deal."

"It's not that. It's...."

"Then what is it?"

I decided I'd just get it over with.

"Dr. Colleen, I totally forgot about what I'm wearing underneath my pants. Since this appointment was last minute."

Dr. Colleen smiled. "I'm a pretty open-minded doctor. I think I can handle whatever you have under there. Whether it's panties?"

I shook my head.

"Dyed public hair?"

I shook my head.

"Shaved bare?"

"Well, yes, but that's not it."

"Unconventional tattoos or piercings?"

Again I shook my head.

"Now you have my interest," Dr. Colleen said. "Drop your drawers. And I promise you that I am not going to judge you at all."

So I unbuckled my pants and revealed my poor shriveled cock in a locked CB6000.

Dr. Colleen pulled on latex gloved and lifted my locked cock. She peered at the plastic that passed behind my testicles. She tugged at it gently and I groaned. She pulled on the lock.

"This is consensual?" she asked.

"Of course."

"Looks like you have some chaffing near your testicles. How long have you had this on?"

"Two weeks, I guess. Fifteen days." I was in one of my longer periods of chastity.

"No masturbation at all in fifteen days?"

"None."

"Wet dreams."

"Uh, no."

"All right then," Dr. Colleen said. She continued with the physical, ignoring the plastic contraption on my cock. There was one benefit to the cock cage. Dr. Colleen was a beautiful woman, and being naked in front of her might have caused an embarrassing erection. There was no danger of that.

"Well, you're in fine physical health except...."

"Except?"

"I'm going to need to examine your penis and testicles more closely."

Before I could answer, she turned on her stool, opened a drawer, and removed a heavy set of cutters. I don't know what they were usually used for, but they made short work of the lock.

"Wait...." I said half-heartedly.

She removed the plastic cage and my cock became erect quickly.

"Excellent," she said. "I was worried about the long-term impact on your erectile tissue. You don't use it, you lose it. Just like any other body part."

She lifted my testicles.

"I'll prescribe you an ointment for this chaffing," she said.

Then she told me to stand.

"Bend over the examination bench," she said.

"But...."

"Bend over, I need to check your prostate," she said.

I turned, exposing my ass to my doctor.

She lubed a finger and inserted it into my anus. I knew when she found my prostate, since my knees went weak.

"Hmm," she said.

She finger-massaged my prostate prompting me to groan, or maybe I moaned. Five more seconds of massage, and my cock exploded in the most satisfying orgasm I'd had in months.

"Oh god, I'm so sorry," I said.

"Nonsense," she said. "It's a natural reaction to your two weeks of deprivation. Think nothing of it."

I couldn't believe when she reached around with a cloth and cleaned the log stream of semen off the paper covering the examination table.

"You appear to be entirely healthy, regardless of your self-imposed chastity. We'll sign off on those forms and get you started on your new job." She snapped off her gloves. "Wait right here." She stood and added at the door. "Leave your clothes off for a moment, please."

She was gone for maybe five minutes. I contemplated the cut lock. My key holder would be pissed and would probably enact a punishment: a self-spanking, or the spiked chastity tube instead of the clear one. It was worth it. The physical could have been far more embarrassing than it had been. Dr. Colleen had been incredibly cool about everything.

Just then she returned with a package in both hands.

"I went ahead and got you some ointment samples," she said. "But I think we can help with the root cause."

She produced a can of shaving cream and straight razor. Before I could say anything, she slathered my balls with cream. In another moment, she was quickly shaving the stubble from my cock and balls with a straight razor. I watched mesmerized and suddenly my cock was growing in her hand.

"Doctor, I'm not...."

"Don't worry about it," she said, distracted by her work. "It's good to keep my razor skills keen."

In a few minutes, my cock and balls were cleaned of hair. Usually I did it myself before I started any long-term chastity. Her work was quite precise, and probably was a closer shave than I could ever do.

She took the CB-6000 and held in her hand, comparing it against my erection.

"I thought this might be a problem."

Her other package was an ice pack. She placed it against my crotch.

"Ah!" I said in surprise, but the ice pack did its job and my cock shrink to its normal shriveled size.

With skill, Dr. Colleen replaced the CB-6000 on my cock.

"It won't stay on without a lock," I said, motioning to the lock she had cut off.

"Oh, no worries."

She had a new lock, which she placed on the chastity device with a click. My cock was locked back up.

"Go ahead and get dressed."

She was out the door before I could ask for the key.

As I was buttoning my shirt, she returned with a nurse. Dr. Colleen handed me the prescription, the ointment samples, and a copy of my medical report.

"Doctor?"

"Oh yes," she said. She showed me the small key. "Nurse Jenny, make sure we schedule Mr. Roberts for a follow-up visit in two weeks for a check on his prostatitis."

Jenny smiled at me and I swallowed. Did she know what Dr. Colleen was doing to me?

"Doctor," I said a little more firmly.

"Better make it thirty days," Dr. Colleen said with a smile.

The nurse looked up. She was more buxom that Dr. Colleen, blonde, and curvy. "Does thirty days from now work for you, Mr. Roberts? Or would you like me to push it out?"

"No, no, thirty days will be fine."

Dr. Colleen smiled. "And make it the last appointment of the day. Mr. Roberts is starting a new job, you know."

As I left the office, Dr. Colleen smiled at me.

I smiled back. It looked like a had a new keyholder.

Thirty days went by far slower than I expected. It was my first time with no safety key. If I wanted the chastity device off, I'd have to cut it off. And then I'd have to change doctors.

In all truthfulness, I'd sometimes used the safety key to take care of myself during long sessions of chastity. A sexually explicit TV show or a pretty girl walking down the street, and I'd be whacking my pud without my key holder's consent. But not this time.

I was in a constant state of painful arousal wondering what Dr. Colleen intended. Had I misinterpreted the encounter? There was no way I had. She'd cleaned my pipes and then locked me back up with her own lock. She clearly wanted to keep me in chastity.

I arrived 30 minutes early a month later.

"Dr. Colleen is running a little behind," the receptionist said. She was getting her coat on, and the waiting room was empty. "But she says you can wait in Room C."

She led me back. It was after 6 and the office was deserted. Room C was the same room as last time.

"She'll be right with you."

I sat on the crinkly paper of the examination table. My heart was thumping. I'd never had an in-person key holder.

The door opened. Dr. Colleen entered, petite, beautiful. Her lips were brighter than last time. Her lab coat covered whatever she was wearing beneath. She smiled.

"Mr. Roberts, I'm so glad you didn't cancel your appointment."

"Me, too," I said. "I mean, no, I didn't, Doctor."

"I've been looking forward to your appointment."

I tried to be suave. "Well, doctor, as my new keyholder..."

"Remove your clothes, Mr. Roberts," she said sharply. She turned and left the room.

There apparently would be no flirting. I dropped my drawers, laying my short, pants, and underwear across the chair. My cock was pushing at the cage, twitching and swelling. I knew what was coming, I hoped.

Dr. Colleen left me waiting for quite some time before she reappeared. She had lost the lab coat. She was wearing a short skirt, tight blouse, and seamed stockings. The high heels gave her an extra three inches.

"Let's get this straight, Mr. Roberts," she said. "I am not your keyholder, your girlfriend, or your mistress. Do you understand me?"

"Yes, ma'am," I said, my throat dry.

"You are my patient. In fact, you are my experiment. I am interested only in your reaction to prolonged penile entrapment. This is not romantic. This is scientific. In fact, you might be the subject of a medical journal paper."

She pulled out her phone and began photographing my straining penis.

"Hold still," she said.

She pulled a measuring tape from a drawer, held it against the plastic cage, and took more pictures.

"I think we can go a size smaller," she said.

"What?"

"Shut up and turn around," she ordered.

"Doctor, I--"

"Mr. Roberts, would you ever like to touch your cock ever again?"

"Yes, ma'am."

"Then shut up. Turn around."

I turned and bent over the table. The paper crinkled under my hand.

"Hands."

"What?"

"Put your hands behind your back."

I did and felt leather cuffs being placed around my wrists. "We use these for psychiatric emergencies," she said.

I heard her take a latex glove from the drawer and snap it onto her hand.

"My first experiment is to see if we can cause ejaculation without erection," she said.

"I don't think--"

She sighed. I heard rustling of fabric. Then I felt Something soft and wet cover my mouth. I gasped and her panties were in my mouth. I tried to shut my lips, but she pressed a spot on my jawline near my ear and my mouth flew open. She stuffed the panties -- black and silky -- deep into my mouth and then covered my lips with a piece of tape.

"You need to listen better," she said.

Dr. Colleen lubed her gloved finger and inserted it into my anus. She found my prostate easily and I groaned with near ecstasy. She knew how to find a prostate.

"No enlargement," she said to herself. "Anus slightly dirty. Some feces in the rectum. You will give yourself an enema before you arrive at your next appointment."

Next appointment? I groaned again as she began to rub the prostate left and right.

"Do you feel imminent ejaculation?"

It felt good, but I didn't feel the inevitable pull in my balls of a good spurt. I shook my head.

I heard the whir of some sort of instrument. Dr. Colleen applied something to the base of my balls. It vibrated and I groaned louder.

Slowly she moved the device from the base of my balls, across my perineum, to my anus. I was suddenly lost in pleasure. She pushed gently against my prostate.

Suddenly, I felt the building of an orgasm. It seemed to travel from deep in my ass to my scrotum, where it surged and bounced between my balls before drippling out of my limp dick. I wanted to shout, but the panties were plastered against my tongue. My nostril opened and I nearly collapsed onto the table.

"Excellent!" Dr. Colleen said. "I knew you could do it. You orgasmed without a complete erection." She leaned around me and I caught a faint whiff of her perfume and sweat.

"I'll need to measure the volume of ejaculate," she murmured. "Then you can dispose of it. Kneel."

I fell to my knees as she scraped the cum up with a metal blade. She placed it into a small test tube and made certain she'd gotten all of it.

"Six milliliters, Mr. Roberts," she exclaimed. "That's quite a lot of spunk! We'll see if we can increase that."

She ripped the tape from his mouth and removed her panties.

"These are soaked," she said. She turned and placed them in the pocket of my pants.

Taking the test tube, she tilted it above my mouth. "Open up."

"Dr. Colleen!"

She reached down and grabbed my balls firmly.

"Open your mouth and swallow this semen," she said softly.

I opened my mouth and she poured the cum onto my tongue.

It was bitter.

"Swallow."

I did as I was told.

"Excellent." She undid the cuffs. "Dress. Our next appointment is in one month." She handed me an appointment card. "Don't be late," she said at the door. "And wear the panties."

The panties were too small and rode up my ass crack. They made the constant arousal I felt even worse. The orgasm she had given me had left me even hornier than before, and the month had dragged. I'd considered cutting the little lock off with a large pair of pliers, but that same day I received the bill from the insurance company. "Prostatitis IIIa Treatment - $400, 100% covered."

Dr. Colleen was being paid rather well for my "treatment"! I laughed and vowed to make it to one more appointment. The constant arousal and stymied erections left me hyper-focused on my new job. And not the least bit interested in the opposite sex, at least on the surface. It had been clear that Maggie the technical writer on my project had been interested. How could I tell her I was unable to seal the deal? It was just better to pretend to have a long-distance girlfriend. Dr. Colleen was effectively a long-distance girlfriend anyway.

Nurse Jenny entered the exam room. "Dr. Colleen will be in in a moment. She said to undress to your undershorts."

Her green scrubs that didn't hide her figure. She turned to the computer monitor in the exam room and began typing.

I paused, ashamed of the fact I was wearing Dr. Colleen's panties. I felt my face flush.

"Go ahead, Mr. Roberts. No need to be embarrassed."

I realized this was all part of Dr. Colleen's humiliation of me. I removed my shirt. Then I unzipped and dropped my pants.

The nurse had watched me out of the corner of her eye.

"Oh my," she said. "Those look like Dr. Colleen's panties."

I blushed, even though it was clear the nurse was in on Dr. Colleen's procedures.

"Turn around." She turned the waist up in the back and said. "These are a little small. We'll get you a larger size."

Dr. Colleen entered then and she smiled at the black lace panties.

"So good to see you again, Mr. Roberts," she said. "How has the last 30 days been?"

"Uncomfortable," I said. Dr. Colleen smiled.

"Of course. But worth it... for science." She turned to the nurse. "Jenny, fetch the package, please."

"Yes, Doctor."

Dr. Colleen lowered the panties.

"Quite a bit of growth. The hair, I mean. We'll have to see about that." She pulled the key from her pocket. "Ready to be let loose?"

"Yes!"

"Turn around," she ordered. She cuffed me quickly. "I can't let you be touching my science experiment." She spun me back around and unlocked the chastity device. My cock sprung to life.

"No sign of erectile decay," she said. She squeezed my cock with a gloved hand. I felt like I'd spray all over her in a second.

"Sit on the exam table." I did and she gathered her shaving equipment. She lathered my testicles and the base of my shaft. I groaned at the attention by cock was finally getting.

"If you orgasm without permission, I will delay our next appointment by 30 days."

"Yes, Doctor," I said through gritted teeth. She scrapped the hair from my genitals, and I tried not to look down her blouse while she did so. Even so, I caught a glimpse of her pale breasts.

She caught my stare and smiled. "Your self-control is weak. No wonder you need a chastity device."

The nurse returned and stifled a laugh at the sight of the doctor bent over cleaning the excess shaving cream from my junk.

"I'll need ice," Dr. Colleen said.

"Yes, Doctor." The nurse laid a box on the counter and left.

Dr. Colleen wiped my cock clean and applied a lotion that soothed the burning. Nurse Jenny returned with a bucket of ice.

"Shrink his member and then we will attach the new chastity device." Dr. Colleen left, and the nurse smiled at me.

"I'm so glad you're abstaining," she said. "Even if you need plastic help. It's so heartening to see a young man willing to reject sensuality."

I jerked as she pushed the ice into my crotch.

"'Your sanctification is the will of God, that you abstain from sexual immorality,'" she quoted. I wasn't sure what to say to that. My chastity wasn't really the will of God. More like the will of my dirty mind.

My cock deflated. "Good boy," she said.

The doctor returned. She examined the cock and then placed the base of the chastity device back behind my testicles. She opened the new box that the nurse had brought. It the same brand as my CB-3000, but small and tighter.

She slathered my cock in lube and expertly slipped the device over my dick before it could grow again.

"All right," she said. "All done. We'll see you next time."

I realized she wasn't going to give me an orgasm like last time.

"But Doctor," I exclaimed. "Don't I need... release?"

"Oh no, not this time. I want to measure the ejaculate after two months."

"But--"

Nurse Jenny giggled. "Poor man," she said.

I couldn't bear the thought of another month without release.

"But what if I have a date?" I asked. "I need to be... available."

Dr. Colleen smiled. "You can date without intercourse," she said. "Do you have an actual date?"

"No," I said dejected.

"What you need is a woman who understands your situation," Dr. Colleen said.

My ears perked up. Maybe Dr. Colleen was offering to date me. She did have the key and if I got her aroused enough she might let me go.

"Nurse Jenny is single," Dr. Colleen said.

The nurse smiled. "Oh, I'd love to date a pure boy like you."

"Then it's settled."

"It's so nice having a boyfriend that I can be free with," Jenny said. We were at her apartment and she was utterly naked. I'd taken her to dinner and she'd invited me back. In moments, she was naked and we were making out on her couch. I'd had the faint hope she had the key. She didn't.

"Maybe you could unlock me so we could... uh..."

"I don't have the key, silly," she said. "I don't want to ruin Dr. Colleen's experiment." She reached down and grabbed hold through my pants of the metal device locked to my cock and shook it.

She jumped up. "Do you mind if I dance for you?"

I shook my head numbly.

I saw Dr. Colleen monthly and Jenny weekly. For 12 months I had not touched my cock directly. My orgasms were strictly controlled and measured by Dr. Colleen. She knew my prostate well, and her stimulation plus a little vibration to my balls resulted in near instantaneous orgasm while still in my chastity device. Afterwards, Nurse Jenny would remove the device while my hands were still cuffed behind me and shave me bald, all the while chatting about this or that.

In all honesty, the hour of detailed ministration by two beautiful women was worth the 30 or 60 days of deprivation and pain as my cock tried to grow against the plastic cage.

"It's been twelve months," I mentioned to Dr. Colleen. "I think you must have enough data for your research paper." She looked at me over the test tube filled with my semen.

"You're so right."

I sighed. It was finally time to remove the cage. Maybe I'd finally get to have sex with Jenny. Maybe Dr. Colleen would like to join in. My cock started to harden as I thought about it.

"Now, now. Don't get too excited," Dr. Colleen said. "We still have one more month."

"One more?" I could do one more month.

Nurse Jenny needed two packs of ice to get my cock down to a manageable size.

"I can't wait for next month," I said to her.

"Mr. Roberts?"

"Yes," I replied. My phone had lit up with a call from Amalgamated Health Care, my insurance provider.

"I'm Valerie Diaz, your health care coordinator. I'm calling about your treatment for your prostatitis."

"My what? Oh right. Yes, it's definitely better," I said quickly.

"That's what your doctor says. The treatments worked well and the inflammation has gone down dramatically."

"There's been very little swelling in that area," I said. I was two days away from getting the device off. My final appointment with Dr. Colleen was that Thursday and I had a date with Jenny Friday.

"That's what our records say," Ms. Diaz said. "Congratulations. For that reason, we've moved your follow-up appointment out six months."

"Six months?" I cried.

"Yes, it's for cost savings. You must understand that the best way to keep health care costs down is to work together to reduce the time spent with the doctor."

"Six months?"

My penis began to grow at the thought, but was stopped evilly by the plastic cage.

"I've taken the liberty of rescheduling the appointment to next June. Have a good day, Mr. Roberts. And congratulations on your recovery."

I hung up the phone and began to weep in frustration and arousal.
