Blue: Always open

"Bl... blue"
I answered more out of surprise than anything. The nurse removed the blue one from the selection "A bold choice for a lipstick color, but you cant go wrong with choosing you favorite color... right?" she semi asked with a knowing grin. I tried to resist, but the restraints that were already holding me in place, and the experienced nurse who seemed to have applied lipstick to countless other in this situation left me with 0% of not coming out of the lipstick being applied perfectly onto my lips.

"All done" she triumphantly announced to me, while the sensation of the lipstick started to settle in. It started with a tingle in the lips that soon turned into a strange feeling of tightness. At first I could barely feel it, but then I could see it... my lips were getting bigger, and fuller. Then the feeling spread up my jaw, and I felt my jaw muscle going limp, loosing the muscles to stay closed.

"You are gonna love watching this next part, I always do" She said while holding up a mirror for me to see.

I could barely believe what I was seeing. Where there normally would have been an image of me in the reflection, all I could see now was some perverted form sitting in its place. With the mouth just hanging open in an 'O' shape. I tried to close my mouth, but all that managed to do was snap the lips into a puckered kissing pose. The moment I tried to relax my lips from the 'kiss' my mouth went back to an 'O' shape, with my tongue lulling out.

"whaa?..." I tried to say, but my words were slurred without the fully needed movement from my jaws.
"whhaaa iiih youu ooo too nee?"
"What I did to you? oh sweet little blowjob ****, you made this particular choice yourself. And don't worry your little head on the difficulty of your speech, you wont need to say much in the future after all. "

The nurse made a little jump
"which reminds me"
Another tray was brought forth. My heath sank looking at the various objects. All the lollipops, pacifiers, dildos and other various objects normally associated with going into the mouth.

Tear were starting to appear as my fright was fully setting in.
The nurse coming ever close while giving that sadistic smile and holding one of the objects in her hand.
"We need to get your lips fully calibrated"
