The first week went by quickly as Nancy learned the ropes of her job. She eventually grew less nervous about procuring urine samples but the excitement never died. Each day she went home with her panties more than a little wet.

But how she loved her job. Some boys remained limp as she cleaned them and had them pee into the cup. Others grew hard as she touched them and these were her favorites. Nancy loved watching their wilted shafts become erect as she carefully swabbed and cleaned with the hygienic pad. Sometimes she would lift up the small penis to tenderly wipe at the wrinkled and hairless scrotum underneath. All the boys were far too young to have developed any significant testicle size but Nancy liked all the same to explore these small marble sized nuggets that she knew would one day grow to the size of pink pong balls.

Uncircumcised boys also became a favorite patient for her. The presence of a foreskin often meant extra cleaning and Nancy was always meticulous in her attention. Some boys had not yet fully retracted their foreskin and she was always careful not to hurt them as she cleaned. Others, however, had fully retractable foreskins and Nancy took great pleasure in handling these little boy penises.

One boy in particular, Jason, remained vividly burned into her memory. Nancy recalled his wrinkled little penis, hidden away by his puckered foreskin. Jason was eleven years old and quite embarrassed to be revealing himself to this older woman. Nancy could tell was very nervous as she examined him and he had vehemently insisted that his mother stay in the waiting room during the exam.

After some gently persuasion, Jason reluctantly let his pants and underwear drop to his ankles and let Nancy proceed with the cleaning. She felt very wet and horny as worked on this obviously uncomfortable boy. She swabbed his penis several times with the hygienic wipe before taking it in her eager fingers. Jason flinched at her touch.

“Don’t be afraid,” she reassured him. “I won’t hurt you.”

Jason blushed even redder at this comment but he let her continue touching him. Carefully, she lifted his penis and gave a few dabs at his scrotum which she noticed had already started growing. Then she gently pulled at his foreskin.

“Have you retracted your foreskin before, Jason?” she asked innocently.

“Oh, umm…” he hesitated, clearly unnerved at this line of questioning.

“It’s okay, you can tell me,” she told him encouragingly. “I’m a medical professional.”

“Yeah, sometimes,” he replied reluctantly.

“That’s good,” she told him. “It’s important for young boys to learn proper hygiene. Do you clean underneath your foreskin?” She squeezed his flaccid shaft and was delighted to feel it pulse in response.

“Um, yeah,” Jason mumbled.

“Very good,” she told him. His penis was now starting to swell in her fingers and she could tell Jason was very embarrassed by this turn of events. She gently retracted the foreskin from his hardening penis, revealing the dark red glans underneath. He was now fully erect although his penis was only three inches in length.

Nancy couldn’t help herself as she softly pulled his shaft, wishing she could jerk him off. Instead, she opened another hygienic wipe and began to clean the thin layer of mucous left behind by his foreskin.

“Ahh!” Jason recoiled at her touch.

“Sorry!” Nancy apologized. She knew that uncircumcised boys were often more sensitive than their circumcised counterparts. One hand gripped his shaft gently but securely as she cleaned him off. Then she positioned the cup underneath his throbbing glans and instructed him to urinate. When he was done, Jason wasted no time in getting dressed again and meekly exiting the lavatory.

Another patient that Nancy remembered well was five year old Timothy. His mother had insisted on accompanying him along each step of the exam, including the urine sample. She pulled a chair into the lavatory and waited while Nancy prepped her son for the sample process.

It felt very odd to be in a room with a five year old boy with his pants pulled down while his mother sat watching. Nevertheless, Nancy did her best to remain professional. Since Timothy had come in on a general examination, Ruth had instructed Nancy to go ahead and examine the boy’s testicles for any abnormalities during the urine sample.

“Timothy,” she said, kneeling down in front of him, “Dr. Parker asked me to examine your testicles too? I’ll be very gentle but you tell me if it hurts, okay?”

“Okay,” Timothy told her agreeably. Nancy glanced at his mom before starting the examination. She appeared a little uncomfortable now but it was too late for her to leave the room.

Carefully, Nancy moved Timothy’s little penis aside, enjoying the feel of his soft skin beneath her fingers. She glanced longingly at the little pink tip of his penis, wishing she could taste it. Her other hand moved to cup his tiny ball sack which was no larger than a teabag. Delicately, she located his tiny testicles and rolled them between her fingers, searching for any abnormal lumps. As she worked, she couldn’t help but notice how Timothy’s penis became erect, the shaft hardening into an inch of firm flesh beneath her fingers.

“That feels funny,” Timothy told her.

“I’m not hurting you, am I?” Nancy asked. She hoped her concern masked the rising tide of sexual energy building within her. Her pussy throbbed with sexual longing.

“No,” he replied. “It feels nice.”

Nancy was taken aback by his words. “Oh really?” she asked nonchalantly. She glanced at his mom who shifted uncomfortably in her chair.

“Yes,” Timothy replied naively. “I like rubbing myself down there too.”

“Oh, I see,” Nancy answered, continuing her exam. She felt uncontrollably horny now. She had been teased all day by the sight of hairless scrotums and wrinkled little penises but this was too much. The twenty nine year old was certain she could come if she so much as caressed her engorged clit. Her wetness had soaked her cotton panties and her head was throbbing with overwhelming sexual desire.

“Why does it get hard?” Timothy asked innocently. Nancy glanced up at his face and saw nothing but young curiosity. “Sometimes it gets hard when I touch it. I don’t know why.”

Nancy looked to his mom again whose face was scarlet. She was clearly at a loss for words so Nancy spoke. “Well, Timothy,” she said, “boys’ penises get hard because…” She didn’t know how to continue.

“It’s okay,” his mom finally spoke up. “Timothy, we’ll talk about this later, okay?”

The little boy nodded, confused about why his simple question had caused such consternation. Unable to help herself, Nancy massaged his testicles and squeezed his little erect shaft for a moment.

“It feels good when you touch me,” Timothy informed her. Nancy smiled at the boy but his mother shifted again in her chair.

“Timothy,” she warned him. “That’s enough. Please be quiet.”

Reluctantly, Nancy finished the examination. She watched Timothy pee into the container and fill it almost to the brim. She was amazed by how much urine some boys could hold in their bladders. Under the pretense of shaking out the last few drops, Nancy gave his little penis a few gentle squeezes. She smiled at him as she did this and was happy to see him beaming in return.

Nancy thought that the encounter with Timothy would be the most blatantly sexual experience during her six week internship. She was wrong, however. Brian was a ten year old boy whose mother had brought him to Dr. Parker’s clinic because of an odd rash on his penis. After several exams and tests, Ruth had decided that the rash needed a topical treatment and prescribed a medicating cream. It was Nancy’s job to show the boy how to properly apply the cream.

“Brian,” she said, “if you’ll follow me into the exam room we can get started on getting rid of that rash.” Nancy noticed how the boy slouched into his chair in the waiting room. He was clearly not happy about being here.

“Excuse me,” his mother spoke. “Do you mind if I come too?”

“Mom!” Brian protested.

“If you want to come, that’s fine,” Nancy told her.

Mother and son followed Nancy into the exam room. She closed the door behind them. “Okay, Brian,” she said holding up a tube of ointment. “Dr. Parker has prescribed this medicating cream for your rash. You’ll need to apply it twice a day, once in the morning and then again before bed. Apply liberally and make sure to work the cream into the skin, okay?”

“Okay,” Brian said, holding out his hand. “Can we go now?”

Nancy shook her head. “I’m sorry, but Dr. Parker wanted to make sure you understand how to apply it properly so she asked me to show you. Could you undo your pants please?”

Brian turned beet red. “But my mom’s right here!”

“Brian,” she spoke, “I need to make sure I understand how to do it too so I can make sure you’re doing it right.”

“I can follow directions!” he protested. “You don’t have to watch!”

Playing the diplomat, Nancy spoke up. “Brian, how about you and me go into the next room and I’ll do it for you, okay? It’ll just take a second. And then I’ll come back and explain to your mom on how to do it.”

“Okay,” Brian agreed grudgingly. He followed her into the lavatory. Nancy shut the door.

“I’ll need you to take off your pants,” Nancy instructed him. “Please?” She waited as Brian undid his belt, his ears a little red. He hesitated a moment before pulling off his white underwear. Finally, he was naked from the waist-down. His eyes avoided Nancy’s and neck and face were scarlet.

Nancy was momentarily taken aback when she saw the size of his penis. She had grown accustomed to the smaller sizes of boys’ penises. Most were usually no larger than a cocktail weenie. Brian’s penis, however, appeared several inches larger than the average size she had seen. Nancy guessed it was about the length of her middle finger, much larger than the pinkie-sized penises she had been working with. Brian was uncircumcised and his foreskin was a wrinkly but protective sheath at the tip of his penis.

Brian must have sensed her staring because he glanced up at her miserably. “Go ahead,” he told her dejectedly. “The guys in the locker room think I’m a freak. They call me names like ‘Rumpled-Foreskin’ or “Wrinkly Dick’.”

Nancy’s brow creased with concern. She patted him on the shoulder. “Don’t pay attention to them,” she told him. “They don’t know what they’re talking about. And I didn’t mean to stare. I see lots of boys with foreskins. There’s lots more than you might think, you know.”

Brian ignored her. Nancy remembered the forgotten tube of medicated cream in her hand. She knelt down before the boy and unscrewed the cap.

“Squeeze a dollop of the cream in the palm of your hand,” Nancy told him, demonstrating. She glanced again at his penis, relishing the sight of its adorable pinkness. His scrotum had also started to grow and his testicles dangled enticingly, just inches from her face. She noted the small red rash that appeared along the skin of his penis.

“Work the cream into your hand for a moment before applying it to your penis,” Nancy carefully took his penis into her hands and began massaging the cream into it. Brian flushed at her touch but she could feel his penis throb in response. Enthralled, she felt the ten year old boy become erect as she worked the cream into his penis.

“Don’t be afraid to apply the cream liberally,” she told him.

Brian was obviously embarrassed by his erection and he avoided her eyes. “Um, okay,” he said, looking at the ceiling. He shifted his weight from foot to foot. His penis was now a full three inches long. She gripped the length of it in her fist, feeling its warm pulse against her palm. Unable to resist, Nancy took a moment to retract his foreskin. The glans of his penis came into view, the dark purple contrasting with the light pink of his shaft.

“Don’t be afraid to work the cream underneath your foreskin as well,” Nancy told him. She applied some cream to his glans, squeezing it gently between her fingers. She noticed how his back stiffened and how his breathing rate changed. Nancy was very turned on now. She fought urge to reach beneath her skirt and touch her aching clit. Instead she squeezed her thighs together and felt her inflamed pleasure nubbin pulse in desire. A powerful grip of sexual craving enveloped her body. Even her nipples were hard beneath her cotton bra.

“You have to be sure to work it in well,” Nancy told him, her voice trembling with excitement. She swallowed hard as she gazed at his erect little shaft. His foreskin had protectively slipped back over his glans. Tenderly, she retracted it again and caressed his glans, pretending to work more cream into his penis.

“Um, I think you better stop soon,” Brian croaked. But Nancy didn’t pay any attention. She continued to jerk off the ten year old boy, her fingers fondling his sensitive glans. Only a minute had passed but it seemed much longer. The inexperienced boy suddenly stiffened his back again and Nancy could feel his penis grow even harder as it throbbed beneath her fingertips.

“Oh!” Brian tried to strangle his gasp of pleasure as the orgasm surprised him. Nancy felt his penis pulse several times as Brian’s dry orgasm trembled his body. He was too young to be producing semen yet but she could feel his muscles clenching and unclenching. Nancy shivered with horniness as she imagined how one day this ten year old boy would be producing semen that he could ejaculate.

His orgasm only lasted a moment and Nancy suspected he had purposely suppressed it out of embarrassment. Reluctantly, she let go of his little penis.

“Please don’t tell anyone,” Brian begged her.

She patted him on the shoulder again. “It’s perfectly natural, Brian. Your body just gave a natural response, that’s all. Honestly, I would be a little worried if you didn’t respond that way.”

Brian hurriedly pulled on his pants again. Nancy washed her hands at the sink before handing him the tube of cream. He meekly took it and jammed it into his pocket. Nancy opened the lavatory door and they rejoined his mom in the exam room.

“How did it go?” she asked them. Brian looked away, still too embarrassed to speak.

“It was fine,” she told his mom. It wasn’t until she had started walking that Nancy realized how wet her panties were. “I think your son will be just fine.”
