Female Doctor Enjoys Little Bro’s Big Dick

All characters are strictly over the age of eighteen



I’m a urologist.

Not many women work in this field, but I chose this specialty because of my fascination with penises. And I get to see many of them. Even though most of my patients are older, I get enough young and middle-aged men to keep it naughty and interesting for me. I’m married to a kind and intelligent man, but sadly, his sexual prowess left a lot to be desired. I loved cock too much to resign a life of sexual unfulfilment.

I checked my patient list and smiled. My last patient of the day was a young man with an erection problem. According to the notes, once his penis was fully erect, it did not get soft, even after an orgasm.

Of course, I didn’t believe it. Probably he experimented with Viagra or something. Who knew what 18-year-olds got up to these days?

I did, however, wanted to see the phenomenon with my own eyes.

There was a knock on the door, and I called out for them to enter.

A young man shuffled in.

“Hey, sis,” he said nervously.

“Hello, Billy,” I said with a smile.

I understood his nerves. Most women didn’t work in the urology field. And he probably didn’t expect his older sister to be looking at his ‘problem’.

Penises always intrigued me. Working as a urologist paid well and got me in close proximity with dicks.

Especially when it came to fine young specimens such as my cute little brother.

“Oh, I thought…” he started.

“That you were expecting doctor Gupta? He had a family emergency and I’m looking after his patients today.”

“Sorry, I didn’t mean it that way. It’s just embarrassing.”

“Nothing to be embarrassed about. I promise you, anything that happens in this room stays in this room. Have a seat.”

He simply nodded and sat on the examination table. I knew he wasn’t fully convinced, probably dreading his predicament, but I found it was best to just push ahead before the patients lose their nerve. My little brother would be no different.

“First, let’s get through all the boring checks. You’re Billy Madison?” I asked, looking over his file on the computer.

“Yes.”

“Eighteen years old?”

“Yes.”

“Do you smoke, drink, or take any recreational drugs?”

“No. Just drink socially.” There was a pause. “Okay, I may have smoked a joint at a house party a few weeks back. Don’t tell dad.”

“I won’t. Doctor-patient confidentiality.”

I looked up from the computer and smiled at him. “Try to relax, Billy. This is just a routine examination. If there are any irregularities, I promise we will find and resolve it.”

“Okay.”

“For now, why don’t we change you out of those clothes? There’s a gown behind the screen. Make sure to take off your shoes, too. I want to give you a full medical checkup.”

He went behind the screen and a few minutes later came out with nothing but the gown on. The front was tied together with ties. He shimmied up onto the examination table, trying his best not to let the front slip aside and expose his penis.

Cute.

I went over and untied the gown. As I pulled the front open, his hands shot over his penis.

“We will start off with an inspection of the genitals,” I said in a very matter-of-fact tone.

“Sis, wait.”

I pulled his hands away from his crotch. I was surprised to see his foreskin covered most of the glans, with the tip still exposed. In most cases, when the penis became erect, the foreskin would roll back, fully exposing the head.

“Excuse me,” I said.

I took hold of his penis and peeled the foreskin back. My little brother’s crown looked like a fat purple plum. I massaged the area with my fingertips, and his dick pulsed and started to enlarge.

“Oh, God, I’m sorry,” Billy said, his eyes wide with shock.

He was mortified to have his cock reaction to his sister’s touch. He had no control over it.

I was sure he would have preferred to stay flaccid, but I wanted him nice and hard. I swallowed as I watched it inflate in front of me.

After it was fully erect, I proceeded to start jacking his shaft, rolling his foreskin all the way back and then up over the head.

“Relax, this is part of the examination.”

“D-do all doctors do this?”

“I doubt my male acquaintances would. It’s very invasive,” I said as my hand trailed slowly up and down his shaft. “But this is the most effective method for finding irregularities.”

“I-I guess,” he groaned.

“Any pain or discomfort?”

“Apart from me dying of embarrassment?
