Derek was 34, almost 35, but his triathlons made him look a decade younger. At 5-foot-8 and 145 pounds, he was the epitome of good health, but yet, he enjoyed going to the doctor.

He wasn’t gay per se, but not straight either. Somewhere in between. And ever since getting sports physicals in school, he had had a medical fetish.

Derek had given and received a few “fantasy” physicals over the years, but they just weren’t realistic enough. He sought a doctor—a real doctor—who would push things beyond where they ought to be.

Eventually someone who claimed to be a family physician responded to his Craigslist ad. Derek and the doctor exchanged a few messages, which included Derek sharing his stats and athleticism. Derek made it clear he expected a “complete physical,” DRE included. The doctor explained it would be best to take a “semen sample,” and Derek agreed.

The “appointment” was set for 8 on a Saturday morning. Derek began the day with a short swim and about a half-hour of weights. Then he showered up, put on a pair of tight white briefs, knee-length shorts, and a cotton T, and headed for the clinic.

Derek was instructed to use the clinic’s back door. He knocked lightly and entered. The clinic’s lights were off when Derek arrived. The doctor seemed nice enough—maybe 45, and in good shape. He smiled, nodded, and eyed Derek’s slender frame, confirming Derek seemed to be telling the truth about the triathlons.

Within seconds, Derek found himself shoeless, on a scale, in a dark clinic hallway. There was some idle chit-chat, the substance of which Derek cannot remember. A couple minutes after that, Derek was alone in the exam room with the doctor, who took a brief health history, instructed Derek to “get undressed,” and left him alone in the exam room illuminated only by early morning sunlight.

Derek kicked off his athletic shoes, peeled off his socks, slipped out of his T-shirt, slid down his shorts, and stood in the dim exam room in just his white briefs.

He wondered whether the doctor wanted Derek completely naked. Derek wanted to be completely naked, and slid off his briefs and took a seat on the exam table. But that wasn’t realistic enough. Physicals begin with patients in white briefs. So Derek slid his back on and took a seat, just before the knock on the door.

“Ready for me?”

“Y-yes, doctor.”

The doctor now had on his white coat. He closed the door, and Derek heard a click. No question about it, the door was now locked. Derek and the doctor—a real doctor—were alone in the exam room, and there was no one else in the clinic.

The doctor stood in front of Derek and instructed him to follow his finger, and then to look into the light. As the doctor examined Derek’s ears and mouth, he inquired whether Derek had had a summer cold.

“Just getting over one,” the 34-year-old said.

The doctor placed a stethoscope on Derek’s back and asked him to take several deep breaths and then to breathe normally. The steth ended up on Derek’s chest next, and then on his carotid arteries.

As the doctor pressed the stethoscope into Derek’s neck, he also pressed his groin into the knuckles of Derek’s right hand that was grasping the side of the examination table.

It was a lump, soft yet not.

“All right, lie back.”

Derek felt his penis stir as the doctor examined his abdomen and then explained that the thumps just above his groin were to examine his liver.

“All right, you can sit up now.”

Derek could see through the gap in the doctor’s coat, and confirmed the doctor was getting hard. The doctor checked Derek’s reflexes next and thought to himself … “Yep, a runner.”

“Well, those work well!”

Derek blushed a little, at getting a compliment from a man who clearly found him attractive.

“Let’s have you stand down and slip off your underwear.”

Yes! Derek obliged and took a seat, buck naked, on the end of the exam table.

“No, stand up.”

The doctor pulled out a little ledge, and Derek stood there, wearing not a stitch of clothing in the dim exam room, as the doctor painstakingly put on a pair of gloves. Then, he touched the athlete’s genitalia.

“I’m examining your testicles now, for any signs of abnormalities.”

Derek looked down at the doctor’s gloved hand, and saw his penis grow alongside the doctor’s index finger.

The doctor examined Derek’s penis next—the length of the shaft, then the tip, spreading the opening and looking closely inside. Derek watched every move. No doctor had examined him in that way before.

“Have you had a hernia before?”

“N-no. I don’t think so. But I am doing some weight-lifting.”

Derek was about half erect when the doctor had him turn and cough.

“Good. All right. Turn around, put your forearms on the table, and bend over.”

Derek felt cold jelly at the entrance to his anus before feeling the doctor’s finger enter just a little bit.

“This is the part that can be somewhat uncomfortable.”

Derek felt the doctor’s finger enter completely inside him. The doctor kept pressing, examining, probing, longer and more intensely than he knew was medically necessary.

“How long since you last ejaculated?”

“Five days, I think.”

Upon hearing that, the doctor pressed a little harder and a little faster. Derek looked between his legs, and although his penis was back to its flaccid state, he saw a thin, clear band of fluid stream from its tip.

“Ugh. I’m sorry. I’m, um, leaking.”

The doctor chuckled a little, and as he withdrew his finger, he told Derek not to worry and again scanned the athlete’s completely naked frame.

Derek wiped the fluid from his penis, but in doing so, masturbated himself a little.

“Let’s have you get back on the table, and lie down.”

Derek reclined as the doctor again pulled out the ledge. Derek jacked his penis slowly.

“We’ll need a sample today.”

The doctor said it with a whisper.

“Sometimes …”

The doctor put his gloved finger back on Derek’s anus, and then inside.

“… this helps.”

As the doctor massaged Derek’s prostate, it didn’t take long. The doctor had a cup at the ready, but he didn’t get it in there in time to catch the thick glob of semen that erupted from the 34-year-old’s erection and landed on the left side of his groin.

“Fuck, yeah!” the doctor said.

Derek pointed his penis toward the cup for the rest of his ejaculation. Maybe half of the semen made it into the cup. The rest coated his pubes and softening penis.

“That was very good. Good ejaculation.”

Derek silently agreed.

“Just relax. Relax …”

Derek closed his eyes and soon the doctor returned with a warm cloth, and cleaned the rest of the ejaculate from Derek’s body.

Derek laid there in the dim room for a bit, before sitting up, and hearing that he was “a very healthy young man.”

Then Derek got dressed. As he walked to the parking lot, he thought about the semen he had left behind, in the cup. Derek had a sneaking suspicion the doctor would be putting it to good use, and by doing so putting the finishing touches on his own personal fantasy.
