It doesn't matter

You don't have to resist touching your cock for very long at all because once the doctor slips another finger into your ass you cum, hard.

"Unh!" you moan as your dribbling prick shoots its load high into the air. The doctor gasps and steps back out of the way, her fingers sliding out of your asshole and she watches as you spurt out pulse after pulse of cum. You grit your teeth and grip the sides of the bed as your body trembles.

You look directly at the doctor, deeply embarrassed but unable to break eye contact. She has a wry smile on her face as your cum begins to rain down, splattering on your face and chest. There is a moment where you lie frozen, staring at the doctor, your face covered in your cum, and then:

"Oh my god! I'm so sorry! I don't know what happened!"

The doctor is a professional, and she says "Don't worry about it. Believe me, it happens more often than you think." And then, under her breath "maybe not that quickly..."

"Here, take this towel. I will leave the room momentarily so you can get dressed and cleaned up." She turns on her heel and closes the door behind her.

Fuck. You wipe as much cum off yourself as you can, then put your clothes back on. Your asshole feels weird. You feel weird. Weird and hot and flushed.

You hear the click of the door and the doctor returns. You can't look her in the eye.

"Well, I think we've determined the cause of your erectile dysfunction is not physical."

You cringe.

"Rather, it's mental. Ruling out factors such as repressed sexual preferences or porn addiction we can make the judgement that it's likely a temporary ailment."

"Now, many men are embarrassed by things of this nature. You shouldn't be. What is important is honesty. I would like you to tell your wife exactly what happened in your physical today. Will you do that?"

You gulp. "Yes, I will."

"Good. Please make an appointment with my receptionist for one week from now. Then, we will monitor your progress."
