No, Collin stay

Collin was about to rush out of the clinic, but he remembered why he was here and what pushed him to come in the first place. He swallowed his pride and looked at Jessie.

"I understand and I find it satisfactory" said Collin feigning confidence. Jessie only smiles at him knowing he was bluffing.

"Very well, Doctor Priima is waiting for you in room 5." Ended Jessie and Collin quickly moved towards it. He didn't want to press his luck with more bluffing. Collin entered the room and it looked like any other hospital examination room. A lovely woman was sitting behind a desk wearing a lab coat. She had dark golden skin with emerald eyes.

"I assume you are Mr Grayson." Asked the doctor

"Yes, I am." Answered Collin meekly feeling less and less comfortable by the situation

"Good, I was wondering if you will come or not. I understand that all this could be quite overwhelming, but I assure you the procedure is safe. The trials are here to analyze the outcome of the second puberty and understand it a little better. Now please undress and go sit on the exam table." Said the Doctor putting a cheap sheet of paper over the exam table. Collin looked around clearly uncomfortable with the fact of undressing in front of a beautiful woman.

"Now now don't be shy, you aren't the first I see. Now undress." Said the doctor with a snap in her voice and Collin followed the command without protesting and began removing all of his clothing and sat on the table. The next 10 minutes were pretty standard medical stuff. Collin's weight, height, blood pressure were taken. He grew fairly uncomfortable when the doctor took some measurements of his genitals.

"Let review this to make sure everything is fine. You are 5 foot 4 and you weigh approximately 115 pounds, your muscle mass is inexistent and your genitals are underdeveloped and smaller than the average. Otherwise than that you are perfectly healthy. There's one more test to do and you'll be good to go. Now get up and turn around." Said the doctor taking a pair of latex gloves from one of the drawers. Collin followed the doctor's instructions knowing full well what's going to happen next.

"Try to relax. It will be uncomfortable for only an instant." Said the doctor putting some lube over two fingers covered by the latex glove. A second later, Collin could feel the doctor right behind him and felt pressure on his anus. Like she said it was uncomfortable for only a moment.

"As expected your prostate is underdeveloped for a man of your age. I want to test a hypothesis, it will take only a second."Said the doctor and before Collin could answer anything she pushed her fingers a little deeper. At that moment, something in Collin exploded. The world around him turn black and all he could feel was an intense pleasure as his cock ejected cum harder than before.

Collin came back to him a couple of seconds later only to find himself on the floor next to a puddle of his cum. "I'm sorry." was all he managed to say. "Don't worry about that. Your prostate is way more sensitive than most normal males." Said the doctor writing something in Collin's file. At that moment, the doctor wasn't sure that the second puberty trial was the best trial for Collin. She was thinking of a more experimental treatment that was more fitting for him.
