Purple: Partial gag/ speach control

"So which will it be"
she showcased the lipstick
"We have red, pink, brown, PURPLE, black--"
"purple?"
"Purple it is then"
"no that wasn't--"
But she was already applying the color to my lips.

When she was finally done, I felt a strange sensation on my lips. It started with a small hot feeling. Then the feeling would spread out a little and subside again before it spread out further and started again. It was as if small hot tidal waves were rolling out, each wave making my lips grow slightly more.

"I really enjoy when I have the chance to use this one. Its so deliciously devious and subtle" the nurse almost said almost giddily.

I though the feeling would stop once it had reached the end of my lips... but to my horror I felt something small were trying to creep in at the corner of my mouth. I tried to keep what ever it was out of my mouth, but the strange liquid feeling seemed to just seep in between and along my pearly whites. I tried to spit whatever it was out, but the insides of my cheeks felt like they were being hit by small wave after wave of heat as the liquid were slowly creeping in. Only slowly subsiding as the liquid were tracing itself all the way to the back of my mouth.

"No need to bother with that silly attempt, Its not coming out. I hear that the girls stationed in the lab were prompted to REALLY inspire the lab boys for this one, and that they did."

Suddenly my mouth got **** open wide. It felt like a piece of chewing gum or something had wedged itself in between my back most top and bottom teeth.
"Ahh, seems like phase 1 is almost done"
The liquid trailed along to my tongue. again the burning sensation. strangely enough, only hitting the sides and edge of my tongue.
Everything in my mouth felt hot and stiff, then what ever had **** me mouth open gave way. and I could move everything again.

"what-- gasp-- what the hell did you do?" I asked, my jaw still feeling a bit sore due to the violent jerk it had been **** to do.

The nurse just smiled at me "like I said, phase 1. Now its time for the next phase."

"Training?" I did not like the sound of that. and I definitely did not like the phallic object the nurse were suddenly showing me.

"What the? get that thing away from-- penis?" huh? I hadn't said that last word.
My jaw got **** open again, but now my tongue were being pulled outward as well, moving around as if trying to reach out for the dildo.
Although my jaws were being held open, I saw, felt and heard my lips move around and the word "PENIS! PENIS! PENIS!" could be heard from them.

"Wait, what the HELL is happening?" I tried to speak, but the sound of my voice were being drowned out by that low feminine voice from the purple lipstick that kept demanding "GIVE ME! GIVE ME!"

The nurse was getting closer and closer to my face with the dildo. "You see, this particular lipstick have a feature that I really enjoy people try to work around. This lipstick function more as a kind of enforced training wheel for your mouth. You could in theory live a completely normal life while wearing this. But most likely, you will either end up begging for it, or the lipstick will do the begging for you."

As the nurse once more drew closer, I struggled in my restraints as best I could to no avail. "You bitch, I will make you pay for this" I tried to scream at her. But it was drowned out by my lips making kissing and sucking and licking motion toward the dildo.
"Please let me taste it. I want to have it in my mouth. I'm begging you! I fucking NEED it in me"
