Adam manages to follow his instructions and is rewarded by the doctor

The next day Adam wakes up with morning wood, which isn't unusual for him. What is unusual though, that Dr. Miller had asked him not to do anything about it. He tries his best to refrain from masturbating throughout the day, but that quickly becomes a real challenge and almost like ****. He just cannot get the image of the pretty young doctor out of his head, and neither the memory of her hands on his tiny dick.
The effects of the salve and pill from two days earlier have worn off by now as well, so that his ability to cum is no longer inhibited and back to normal. The urge to relieve himself is all Adam can think about.

The promise and anticipation of daily hand-jobs by the gorgeous blonde doesn't help his condition either, but at the same time it is also all that keeps him from succumbing and touching himself. He doesn't want to disappoint the doctor. Afraid that she might cancel the offer of this special treatment, in case he should turn out to be an unreliable test subject, who is unable to follow a few simple instructions. Like not to masturbate.

What this all adds up to: While he was used to masturbate more than half a dozen times daily, sometimes more, at the time of his appointment Adam has gone for almost 48 hours without release. He is horny, he is hard, and his balls are filled to the brim. His dick is aching and ready to burst. And as he arrives at the clinic, it almost does.

Instead of being let in by the buzzer, Dr. Miller personally opens the door. The young blonde, who was absolutely professional on his last two appointments, is now dressed only in tight and very short hot pants, that shows of her legs and hips, and a low cut top that shows more than generous amounts of cleavage. If Adam's dick hadn't been hard already, this sight now would have made certain of it.

"Hello Adam! I hope you don't mind my casual attire. But since the clinic is closed on Sundays, were all alone. Additionally, since were going to start the scientific trials and i need to make sure that your penis is fully erect for the control test..."

At that moment her hands move up to her breasts and push them together, causing her tits to almost spill out of her top. Surprised at this unexpected deviation from the doctors very professional behavior on his previous appointments, all Adam could do was stare with his mouth open and drool over this mesmerizing display of the doctor's boobs.

"... i thought that today i could do away without changing my clothes, and help you with visual stimulation. I see that you approve."

Dr. Miller seems to smile genuinely at Adam's reaction, which confirmed what she already knew, that she was quite gorgeous and sexy. The blondes hands leave the side of her breasts, as she continues to talk. But Adam does not hear the words. All he can see, all he can think of: Breasts. And the doctor apparently realizes this as well.

"Adam?"

The young man is shaken out of his trance by the calling of his name.

"Good, looks like your back. Let's move to my office to start the control test."

They move past the now empty reception, and into the doctor's office. As soon as they arrive in it, Dr. Miller puts on a coat. It's wide open and doesn't really cover anything, leaving Adam free to ogle the sexy body in her skimpy attire. Still, it looks like the doctor's attitude is immediately back to fully professional.

"Please undress and lay down, so we can start with the control test."

She guides Adam towards a hospital cot. Still uncomfortable and self-conscious of his tiny dick, Adam's face slightly reddens. He knows that she has seen everything already on their previous session, and the prospect, that the beautiful woman was about to give him a hand-job, makes sure that he does not hesitate and follows his instructions. Now naked, he lies down, his small, but fully hard dick on full display.

"It looks like your penis is already erect, good. Now please tell me, have you masturbated since your appointment yesterday?

"No..." Adam stammers, painfully reminded of the pressure he feels between his legs because of this.

"Good. It's important for our trial that you follow my instructions. Let's proceed then. First, let's document the length of your erect phallus before we begin treatment with the 'Quickshot Cure'. "

After putting on gloves, the doctor uses a measuring tape and notes down the value with pen and paper. "Okay, still at scrawny 3.5 inches"

Adam winces at this humiliation, but his mood immediately swings back up when he hears the doctor's next statement.

"Now for the control test, i will use my hand to stimulate your penis. Additionally, I will measure the time until you achieve ejaculation. In the unlikely case that it should be necessary, we will repeat the process until your penis loses it's erection. Are you ready? Shall we proceed?"

"Yes, please!" Adam eagerly replies without delay. What he had been waiting for all day was about to happen.
