Female Doctor Enjoys Little Bro’s Big Dick by StasiaGrey..,

Introduction: Doctor Tina treats her younger brother who has a 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? Everything feels fine. Good even,” he groaned.

I smiled and continued.

As I milked his cock in slow, languid strokes, his body would pulse against me. Precum leaked out from the tip. No man could resist my hand job techniques.

“Sis…” He said, his face went tight.

“Are you in any discomfort?”

“No, I- Please you gotta stop, I- Oh, shit..! I’m so sorry!”

I didn’t plan to make him cum. Not at least after a few appointments, but my plans went straight out the proverbial window as a fountain of cum blasted out from his cock.

“Fuck, stop,” he begged.

But I couldn’t stop. One of my addictions was to watch a man as he climaxed, watching his face as he endured the throes of pleasure.

I furiously pumped his big thick cock, forcing hot spurts of cum to shoot out from his tip. His body was tight with tension and his face was a mask of post-orgasmic bliss.

Cum sprayed everywhere. It spurted out like a geyser, hitting his navel, up his chest and the sleeve of my doctor’s coat. Some even stained my hand, not that I minded.

I didn’t want to spoil his orgasm, so I continued pumping his cock until he was completely emptied out.

“Oh, God,” he huffed. Spent, his body relaxed and fell back onto the examination table, gasping for breath.

I let go of him, which was still shockingly erect. It was sticking straight up like an obscene golf flag pole.

While he recovered, I got on with the task of cleaning up the cum with some disposable towels. Semen was everywhere, so it took a while. It was all over him, all over me, on the examination table, and on the tiled floor.

“I’m so sorry,” he gasped.

“Don’t worry about it. I should take responsibility too. I didn’t notice the warning signs of your pending ejaculation fast enough.”

While I wiped up his cum, he continued apologizing.

I walked over to him and grasped his cock. I just loved how it pulsed in my hand.

“Don’t apologize. You did nothing wrong. What happened is a normal physiological reaction. When your penis is stimulated, the reaction is inevitable. Don’t be ashamed of enjoying something natural.”

“Thank you,” he mumbled.

“There is no problem with his erection, from what I observed.”

“But it’s still hard,” he said, pointing to his painfully erect cock. “It only gets soft after cumming several times. Girls can’t seem to deal with it.”

I climbed up on the table with him and knelt between his legs. These were solidly built tables- I had full confidence that it would support both our weights.

“Young ladies nowadays can’t seem to appreciate a good thing when they see it,” I breathed. He didn’t stop me as I got dangerously close to his member. I inhaled, drawing in the thick masculine aroma that went straight to my aching pussy.
