His erection

You take Corey's Member in your hands and examine it; even fondle it while looking over every inch. It's small...about 5 ' inches. His sacks were small too.

The teen moans a bit as he's getting harder.

Seeing a perfect opportunity to gain a sperm sample, you grab a small plastic cup and point Corey's Member into it. You play with his sacks until he cums into the cup. Once he was done, you set aside to send to the lab later.

When Corey's cleaned up, you put on your stethoscope and listen to his heart. It's beating healthy, and you play with his nipples to see if it makes his pulse quicken.

It does.

Getting an idea, you pull out a few small vibrators and switch them on after taping them to Corey's nipples and Member. The teen can't moan loud, thanks to the ****, but does quietly. He's getting turned on...

After that, you take out a flexible dildo that has markings on it, like a ruler. Raising the table a bit, you say, "I have to take your temperature now, Corey. This is a very special thermometer, so I need you do as I say."

"...yes...Doc..."

"Good boy, now then..." You open Corey's mouth with two fingers, and then insert the dildo down the teen's throat. He gags a few times, but soon his throat starts to widen and open to accept it. You stop when the mark hits 5'inches, and withdraw it.

"You have quite a fever, Corey." You say, while writing the results in a special notebook you keep for things like this. "I believe I'll have to examine your insides to make sure nothing is infected."

"Go...ahead..."

You pull out the stirrups and put the boy's feet in them, then slip on gloves and finger Corey's entrance before opening him up with a spectrum. Seeing his anus was healthy, you remove the tool and insert of the dildo you used before.

Slowly you stretch him out, Corey keeps moaning and is nearing his limit. You make him able to take 4' inches of the dildo; not a bad start.

Once you record it and clean your tool, then take another sperm sample when Corey cums.

After you clean up and redress the teen boy, you take out the pen light again and make Corey follow it.

"You will remember nothing of what we did." You say. "Only that I removed your cast. Understood?"

"...yes...Doc..."

"Good boy. Now, do you live alone?"

"Yes...I have a apartment...my folks rent...to me..."

"I see. Now Corey; once a month you will come to my house for a full examination. You will tell no one. Understand?"

"Yes...Doc..."

You nod, and then bring Corey out of it. He doesn't remember how he passed out but he heads home anyway after thanking you.
