The nurse cinches the straps downa nd grins at you. "Don't worry. This is all part fo the process to take care of your buck teeth."
"Huh?" You stare at the guy. "What the fuck are you talking about? I don't have buck teeth! Let me go, you asshole! DAD!"
The nurse grins and pulls your shirt up. "The walls are soundproofed. Anyway, you 'dad' is probably getting taking care of himself." He pickes up a scalpel from the table and uses it to slice the front and sleeves of your shirt, then pulls it off you. "Not bad for your age, kid. Good muscle tone." He slides a hand over your hairless chest.
"Get away from you, you perve!" You pull against the straps, angry, but also getting hard. You aren't into guys, but at 15 you get a boner from almost anything, including getting your chest and stomach stroked.
"Aw, let's see who wants to come out to play." The nurse slices open your pants and undershorts with amazing skill, and reveals your 5-inch hard-on. You flush, knowing it isn't all that big, but you are as big as most of the boys your age that you've seen.
"Don't worry. We'll be fixing that along with your teeth." He grins and pulls your sneakers and socks off, leaving you totally naked in the chair.
"What the fuck are you talking about?" You are still angry, but are also getting really scared. No one has come, even though your dad is supposed to be in the next room.
The nurse smiels and goes over to pick up a chart. "OK. I'll get you prepped for the doctor now. We'll get your buck teeth done first."
"What is with the buck teeth? My teeth are fine! I wore fucking braces for three years to get them perfect!" You watch the nurse pick up a toothbrush and a jar with some weird-looking orange paste in it.
He comes over and sticks the toothbrush intot he paste. "You'll like this - it's carrot flavored."
"Fuck that!" You struggle against the straps, but it's no use.
He shrugs. "It's either get your teeth brushed willingly, or I will use that big hypodermic on the table to paralyze you and do it anyway."
You see the hypo on the table - the needle is at least 6 inches long. You don't like carrots, but you can't escape if you are paralyzed. "Uh, OK. Go ahead."
The nurse starts brushing your teeth very efficiently. This is too weird - the paste does taste like carrots, but it really isn't bad. He does a thorough job, and your teeth tingle and feel sorta odd. Why do they seem bigger? Then he has you rinse and spit into a bowl he holds for you. The tingling doesn't stop, and you realize you can barely close your lips. "What the fhuvk?" Something is messing up your tongue.
The nurse grins and holds a up a mirror so you can see yourself. You scream when you see the reflection. Your whole mouth is distorted, pushed out and filled with huge, flat-looking, protruding teeth. "You FHUCK! What dhid you do to me?"
"Just got you ready for the Doctor, Ben. Don't worry. Those teeth will look just fine when he's done with you." The nurse chuckles and strokes your cock. "And this is going to be magnificent."
The door opens and another man comes in, obviously the Doctor. He picks up the chart and glances at it, then smiles at you. "So, Benjamin. We have something special for you today. I see you already have some lovely teeth. Now we'll make the rest of you match."
Shit! These guys are crazy! And maybe you are too. How could brushing your teeth change them like this? It has to be some kind of illusion. Drugs! The toothpaste is drugged and making you see things! That has to be it. But you are so harny, and the nurse keeps stroking you. Oh, fuck! You're gonna...
The nurse grins as you shoot your load, splattering your own chest. "That's the last human cum you'll ever make, boy."
"Huh? What are you talking about?" If you were scared before, you are terrified now. Are they gonna cut off your balls?
The doctor picks up the chart again as the nurse wipes you clean with a damp cloth. "The next time you cum, the seed is coming from the balls of a...."
