Part 1

The second year after graduating from college, I was living in my old college town painting and sculpting by day, waiting tables by night, and not making nearly enough money to pay the bills. I was sweating making the rent, two months behind on my car payments, every art supply store in town was cutting off my credit, and my only source of nutrition was the free meal I grabbed at work every night. I was getting desperate enough to consider getting a real job when I noticed an ad in the local newspaper.

It read "Practice Patients needed for nurse clinician program. High hourly pay. See Dr. Brown at University Hospital." I was out of paint and canvas anyway, so off to the university I went. Dr. Brown turned out to be a 30-ish, good-looking brunette who told me the nurse clinician's program needed patients for the senior students to practice assessments and procedures on, and each student would pay $200 directly to the patient for the privilege. Since there were 18 students in the class and every assessment would take about a half an hour and no one else had applied for the job, I could rake in a potential $3,600 for a good day's work. I was seeing dollar signs and neglected to ask Dr. Brown what an assessment consisted of when I agreed to show up the next day for the class.

At 8:00 a.m. the next day in a small room adjoining the classroom, Dr. Brown handed me a typical backless hospital gown and told me I could change right there. I thought she was going to leave as I started to undress, but she puttered around in the room getting a few items as I took everything off and put the gown on. She noticed me clutching the back of the gown together, looked me in the eye and with a sly smile said, "Hope you aren't shy around women, because the entire class is women from 21 to 40 years old, and they are going to really look you over inside and out."

I followed Dr. Brown into the classroom where she introduced me to the 18 students and motioned for me to climb on an exam table. She proceeded to measure my height and weight, take my blood pressure, listen to my heart and lungs, look in my ears and eyes, take my temperature orally, and finally look down my throat. She slipped on a pair of gloves, asked me to stand at the edge of the table, slipped the gown off my shoulders and allowed it to drop to the floor as she sat on a stool in front of me.

As I felt 18 pairs of eyes glued to my crotch, she proceeded to detail to the class how to examine the male external genitalia. She retracted my foreskin, commenting to the class on how to do it. She handled each testicle, explaining that she was checking for lumps, and finally asked me to cough hard as she tugged on my scrotum. She patted the exam table and asked me to bend forward. I felt her spread my ass cheeks and felt something cold and wet at my anus.

"Relax," she said, "you'll only have this done 18 more times."

I felt her index finger enter my anus and probe around. I felt like I was electric-shocked and gave a little grunt when she touched my prostate. She described to the class what she was doing and what she was observing, minute by minute, until she withdrew her finger and told me to put my gown back on. I was sweating as she called a student's name and a rather large, heavyset woman in her 40s approached me and commenced taking my blood pressure, pulse, height, weight and mimicking what her instructor had done.

She slipped the gown off my shoulders, sat on the stool and did my genitalia exam like an expert. She had me lean over the table for the prostate exam and was just a little rough, but was quickly done and I was instructed to put the gown on again.

The instructor called another student's name, and this one happened to be a woman I had taken an English class with. She was my age, blond and attractive, and gave me a wink as she started her exam. Things were going well until I dropped the gown and she looked at my nearly erect penis. My face was beet red as Dr. Brown pointed out that my penis was erect and therefore there was no need to retract my foreskin. The blond instructor gave me another wink as she hefted my testicles and then patted my butt telling me to turn around for the prostate check. She located my prostate easily and proceeded to massage it expertly. I couldn't help but moan as she continued the contact of finger on prostate a little longer. She instructed me to put the gown back on, and as I turned around a small line of precum dripped off my penis, hit the floor, and to my great embarrassment was noticed by Dr. Brown.

"Class, occasionally during routine prostate exams some prostatic fluid is produced and one may actually collect a semen sample by stimulating the prostate."

The next 16 students performed their exams, and I got progressively more erect and stimulated. As the last student was performing the prostate exam, I was bucking back against her finger and moaning. I heard giggles from the class and happened to see a knowing smirk on Dr. Brown's face. I leaned back panting and sweating on the exam table with my penis pointing towards the ceiling as Dr. Brown asked me if I would mind if she demonstrated the procedure for collecting a semen sample by prostatic massage. I mumbled my consent. She patted the table and told me to lay on my side in the knee-chest position.

She put on another set of gloves and lubed the finger, even though I had enough lube in my ass to do a set of wheel bearings. She motioned to the older 40-ish student to come forward and told her to take a sample bottle and hold it at the tip of my penis.

While detailing to the class what she was doing,she inserted her finger in my anus and started massaging my very stimulated prostate. Her other hand reached between my legs and grasped my throbbing penis and made sure the tip was in the wide-mouthed bottle. I was really bucking back against her finger as she stroked my cock. As everyone was crowded around the table, I had an earth-shattering orgasm and shot a load of cum that filled half the specimen bottle.

I lay there panting and exhausted as Dr. Brown told her students to leave my checks with her as they left. As soon as they were gone, she leaned over, kissed me on the ear, told me I was great and hoped I would sign up for the catherization class.

Part 2

I took the money I made as the guinea pig for Dr. Brown's nurse clinician class and paid my debts around town as well as my back car payments. By the time I made it to McGovern's bar to pay my tab, I was down to my last thousand bucks. Pop McGovern had let me slide on my tab for almost a year because I had convinced both him as well as his cute barmaid of a daughter into thinking I was a top-notch artist just waiting for my lucky break. Pop was surprised when I paid my tab in full, and when he asked if I had finally sold a painting, I told a big lie and made up a story about how I was selling my stuff left and right.

Both Pop as well as his daughter seemed really pleased with my new-found success and bought me a couple of beers. The bar was fairly crowded and lots of my friends and former creditors were hanging around. Pop, as well as his daughter, made sure that everyone knew how successful I had become, and I was buying drinks for all my buddies and bragging. I had failed to notice the cute blond from Dr. Brown's class sitting behind me taking all of this in until she stood next to me and leaned in to whisper in my ear, "Congratulations on your success, but we both know how you made your money. Shall I tell everybody how you were moaning when Dr. Brown was reaming your ass, or do you agree to do as I ask?"

I mumbled my agreement, and she whispered that I should be at Dr. Brown's office at 8:00 the next morning for the catherization class.

I tossed and turned all night, sweating about the class and how I didn't want my friends to find out how I "earned" my money. At 8:00 a.m. the next morning, I was knocking on Dr. Brown's office door. The cute blond answered the door and with a smirk waved me inside.

"Dr. Brown and the class will be here in a half hour, so you'd better get undressed. I'm sure you remember Claire from the last class, and I know you remember me from English class. You can call me Nurse Cathy. Or better yet, Mistress Cathy," as she gestered to a short, heavyset woman who I vaguely remembered for her roughness.

I reluctantly and rather slowly started to remove my clothes with the two women watching me. I had just removed my boxers and was reaching for a backless gown when she came up behind me and cupped an ass cheek in each hand.

"I've always thought you had a cute butt," and with that she slapped me hard across the left ass cheek.

I jumped and she laughed and said, "I have all kinds of plans for you, sonny boy, and so do several others in this class. If you behave and follow directions, nobody will have to find out what a liar you are, and if you don't behave, you'll get worse than this," and she slapped my right ass cheek really hard.

Claire suddenly walked up and grabbed my penis, which had decided to shrink back to nothing. " I'm learning how to pierce body parts, and I noticed in the last class that you were not circumcised. I've never pierced a foreskin, so I want to look at yours to see where it can be done." She pulled me by the penis over to a stool where she sat down with my penis at eye level. She retracted my foreskin several times, and I started getting hard. She let go of my foreskin and grabbed my scrotum and moved my balls around in the sac. "There are a few good places here to pierce as well." I shuddered at the thought.

Noises could be heard coming from the classroom, so Claire stood up and said, "Show time, big boy."

Part 3

Cathy threw a gown at me and said, "You won't be wearing this long, but we have to be professional. Wait here for Dr. Brown," and they went into the classroom. I sat there for a few minutes wondering what I had gotten myself into, when Dr. Brown came in all smiling and happy.

"I didn't think we were going to get a male patient for the catheterization class. I can't thank you enough for doing this. We have 16 students, plus Cathy and Claire, whom you already know. But you will only have to be catheterized by three of them, and I will numb your urethra before each time."

She took me by the hand and led me into the classroom and introduced me to the 18 students, all of whom were young women. I was directed to an examination table where I lay down and Dr. Brown immediately began describing in detail the catheterization purpose and procedure for a male patient.

The class was divided into three groups. A nurse in each group was to catheterize me as the others observed. Dr. Brown motioned for Cathy's group to come gather around the exam table. "Cathy has the first opportunity, since she is largely responsible for our guest volunteering."

I could feel my face redden as Cathy stood next to me at the pelvic level and raised the gown above my waist exposing my penis and scrotum for everyone to see. She put on a pair of sterile latex gloves and then grasped my penis between her thumb and forefinger, moving back my foreskin. I was already semi hard. She opened a pack containing some soap solution and gauze and swabbed under my foreskin as well as completely down the shaft.

Dr. Brown said, "I'm going to numb his urethra with a cetacaine solution prior to each catheterization," and she inserted the nozzle of a sterile plastic tube connected to a 3 cc syringe into the tip of my penis. It was cold and tingled a bit but didn't hurt at all. I thought, "This may not be too bad."

Dr. Brown nodded for Cathy to proceed. Cathy opened a sterile package containing what looked like a small, red rubber hose and took it in one hand and lubed it with sterile KY jelly. She grabbed the tip of my penis with her left hand and moved my foreskin back with her thumb. She guided the rubber tube into my urethra with her right hand. I didn't feel much until she had fed six or eight inches of catheter into me and it started to burn and I jumped. Cathy grabbed me by the scrotum, squeezed lightly and hissed, "Don't you dare move."

The other students as well as Dr. Brown caught this, and I heard a few chuckles and whispers. Cathy fed more catheter into me, and I thought my cock was on fire. I felt I had to pee badly all at the same time. She connected the catheter to a plastic line leading to a bag and urine started to fill it. Dr. Brown commented on Cathy's technique, pointing out a few things and recommending not to grab the patient's scrotum if they move, and then instructed her to remove everything. Cathy grabbed the catheter, released the air which was holding it in my bladder and slowly eased it out. I jumped again and grunted, so she squeezed me by the scrotum again and said, "Lay still." Finally, the catheter was out. I felt like my cock was on fire, and I could feel tears in my eyes.

Dr. Brown told the class to take a 15-minute break to allow me to recoup, and she left the room. About half the students left the room as well. I pulled the gown down and got up, but Cathy stopped me, looking very angry. She lifted the gown up in back and said, "Bend over the table. I told you to behave, and you didn't."

"I'm sorry, but it hurts," I stammered.

She opened the gown wide in the back and slapped my ass four times on each cheek. "That's for moving and this is for not addressing me properly," she said, and hit my ass four more times. I was mortified as the rest of the students watched the whole thing knowingly, but even more mortified to see that I had a full erection waving around. Cathy reached over and grabbed me by the cock saying, "He evidently either likes the catheterization or the spanking." She stroked my cock a few times, and I let out a small moan which resulted in a few giggles. She squeezed my cock hard and I yelped as I quickly lost my erection. "Can't have you in that state for the next group," Cathy said.

Part 4

Dr. Brown and the rest of the students started back in. She called for the next group to gather around me and looked at me sort of funny because I was already lying there with my gown up. "Our patient is evidently eager to get started, so shall we?" she said with a grin.

She called a name to do the procedure, and I recognized a young girl that I used to joke with who worked at the 7-Eleven part time. The young girl, Anna, smiled at me and promised not to hurt me. The procedure went about the same and hurt about as much. I tried not to move or make noise, but did both anyway, and Anna had to repeat a few things. She completed everything to Dr. Brown's satisfaction and removed the catheter. Dr. Brown announced a break and left with just a few students.

I sat up again, and almost as soon as I did Cathy was there in my face. She ripped the gown off me, leaving me sitting there nude. "You cost Anna some grade points and are going to have to pay for it. Stand up and bend over. NOW!!!"

Everyone watched as I bent over the exam table with my ass in the air. Cathy said, "Anna, would you like to do the honors?" Anna was behind me in a flash and hit me six times on each cheek.

"Not enough," Cathy said, "Hit him eight more times." Anna hit me hard on each cheek, and I yipped after the last one. There were lots of comments from the onlookers, and again I was rock hard. Cathy squeezed my scrotum hard this time, and as I squealed, my erection magically disappeared. She yelled at me to lay back down and behave or I would be really punished.

I got back on the table as Dr. Brown came back, looked at me, and then Cathy, and just shook her head. She called for the last group and for another young woman named Jill, who I also knew from around campus. Everything happened as before, except this young girl was nervous and put excessive KY on the catheter as well as my urethra and her little hand kept slipping. She ultimately jammed the tip of the catheter under my foreskin and I jumped and groaned. Dr. Brown coached her through; however, it burned like hell all the way to my bladder, and I couldn't help moving. She finally got it done and then removed everything, to my great relief.

Dr. Brown thanked me again, dismissed the class and left, winking at me as she did. Nobody left, and Cathy was right next to me almost immediately. "You really messed up Jill's grade," she hissed at me. "Roll over and get your ass in the air," she said. I immediately complied and rolled over on my knees, head down, ass in the air.

"Jill," Cathy said, "would you like to teach our patient a lesson?" Jill was there quickly and slapped my ass hard, at least 12 times with her hand. As before, I was hard as a rock. I heard the sound of rubber gloves being snapped on and looked to see Cathy standing behind me with gloves on. "None of you got to see Dr. Brown collect a semen sample from this patient, so I'm going to show you how she did it."

I felt her index finger enter my anus and touch my prostate. I jumped and she slapped my ass with her other hand. I moaned and pushed back against her finger. There were several chuckles and comments such as, "He really likes it up the ass." I noticed Claire behind me with a camera. Cathy did a play-by-play as her finger did circles over my prostate, and I moaned. "Roll over and face the class so they can see you cum," she yelled in my ear.

I quickly rolled on my side, looking into the smirking faces of the class. She continued to massage my prostate and work her finger in and out of me. I moaned louder, breathed more rapidly, and pushed back against her finger. I looked around at the women looking at my cock, which was enormous. She reached between my legs and gently rubbed my scrotum and I exploded cum across my chest and onto the floor. I heard some light applause and a few "way to go" Cathy's as the class gradually left the room.

Cathy pulled off her gloves and said, "Get dressed and leave now, but don't think you are off the hook. Claire has a piercing class she needs you for in a few days, and I'm soaking wet, so get your tongue and lips to my apartment now!"
