As the device tightened, holding her mouth open, Tessa wondered whether maybe she had made a mistake. She thought she was an accomplished slut, there was nothing I could do to her that she couldn’t handle! I told her I had something fun to inject into her lips and she laughed. That was it? She eagerly agreed, thinking there was no downside to FREE plastic surgery. At the very worst, she might just have to give up sucking dicks for a while until it wore off. Big deal…
She was a little less confident when I pulled out the dental gag. She wanted to know if it was really necessary. I said probably not, but if her lips were to touch each other during the process, her brain might literally implode because of pure sensation overload. She laughed, chiding me for misusing the word literally when I clearly meant figuratively. When I smiled and shrugged, pulling out a large syringe filled with pink goo, she stopped laughing and tentatively agreed to have her mouth clamped open.
The procedure was unremarkable. I mean, as unremarkable as injecting a mysterious pink fluid into a woman’s lips while her mouth is held open can be. I chuckled at her moans and groans as i slid the fine needle inside her, slowly emptying the liquid. When the vial was empty and her lips were swollen and pink, I told her to sit still for one hour while the goo did its work. She lifted a hand, about to touch her tingling mouth, but seeing my smug smirk, thought the better of it and decided to wait.
After an hour, I returned. She was visibly aroused by this point, but was still managing to stop herself from touching, which must have taken some determination because her lips were still swollen and throbbing. When she saw me, she blushed a deep red and her hand shot out from between her legs. I giggled to myself at her embarrassment. Thinking that this was nothing compared to what was about to come I removed the device holding her now neon-pink mouth open.
She stared at me, wondering what the hell I had done to her. Her mouth was so sensitive! It was throbbing and making her dizzy, like she her pussy when she was super horny… only different. She sat with her mouth still wide open, afraid to close it. There were some sensations emanating from her lips that she couldn’t quite comprehend, like there were now TWO pussies on her body, but that was impossible…. right?

My interested leer made her nervous as a shaking hand rose to her face. She had no idea, but the pink color would never fade. She was going to be stuck looking like a bimbo. She moaned a little, feeling air on the sensitive skin…. How was this possible? WAS it even possible? No, of course not, this was some kind of mind trick! Once she touched her lips she was going to find out that this was all a big trick-
She came.
As soon as that finger touched her mouth, she started an orgasm that rocked her entire body. Her eyes rolled up into her head, her hips started bucking, and her body writhed in an all-consuming pleasure the likes of which she had never imagined. I giggled and unzipped my fly, fishing my hard cock out of my pants and stood there waiting for her to notice it. As she spasmed uncontrollably, sucking on her finger and squealing like a slut, something inside her vaguely recognized that this was really wrong.

But then she caught sight of the erect cock in the room, and that thought vanished along with any semblance of self control. She leaped to my feet and immediately started kissing it, smooching it, screaming in pleasure and generally just impaling her face on it. I just stood there, letting her do all the work as she shuddered in an artificially forced orgasm again. There were no thoughts in her head that weren’t “COCK!” in bold, underlined italics and 72 point font. The sensations shooting the short distance from lips to brain simply drowned everything else out. The little blowjob machine she had become just sucked endlessly, rubbing my cock all over every inch of her slutty punk lips, groaning a primal, involuntary noise. When I came she held it in her mouth eagerly, slurping on it and cooing as her lips tingled pleasantly wherever the cum touched.

Unbeknownst to her, the goo in her lips had created a brand new extra pussy. One many times more sensitive than the one between her legs. Her lips were now equivalent to clits in terms of erogenous heirachy, she would never again prefer being fucked over sucking a cock. Her perception of her mouth would slowly change, from being an orifice for eating and communication to just a hypersensitive sluthole for as many cocks as she could get. The only respite from the throbbing, aching need her lips felt would be when they were momentarily soothed by cum. Only then, with white sticky goop dripping from her mouth, would she be able to think straight.
But not even that would sate the hunger she now felt. The deep, insatiable need in her modified lips for pleasure, for cocks, nipples, pussies, balls, anything she can wrap her lips around and suck. She won’t be able to help herself, the temptation to suck would be too great that even though she may not want to, she’ll impulsively seek out things to suck every minute of every day. She’ll likely even suck in her sleep. Actually scratch that, she’ll likely never sleep peacefully again, due to her being unable to bring herself to stop licking her lips. She might lose consciousness from cumming her brains out too hard, sure, but she’ll find it almost impossible to rest otherwise.

I couldn’t even tell if she understood me while I explained her new situation to her. She seemed distracted as she ran a finger along her bottom lip, shuddering hard. The look in her eyes asked me how I could do this to anyone, how could I condemn a person to a lifetime of this, a neverending quest to find another cock and sate the aching, overwhelming NEED she now felt? How could I do this to her, when all she wanted was a little temporary fun? She couldn’t actually ask it though, as her mouth was now far to sensitive to allow her to produce any kinds of sounds other than involuntary squeals, so I decided not to answer it. Instead I offered my hardening rod again, for her to pleasure herself on. It’s such a cute sight to see a woman totally exhausted from pleasure frantically, desperately drag herself across a room. It’s even cuter when she starts moaning in ecstacy from only a mouthful of man meat.

And the best part? (for me anyway)… This is not a chemical addiction. This is not any form of mind control. She’s just too weak to fight the pleasure. She’ll go through any humiliation willingly if the reward is cock, because deep down she just knows she’s to pathetic to fight her desires. She needs nothing more now than to be a fuckdoll. To feel cocks shoved down her throat and a belly bursting with nothing but hot jizz. To be so overwhelmed from pleasure that she passes out, and then wakes up to do it all again. To be grabbed and facefucked until tears and cum stream down her face and over her swollen pink lips, every single day for the rest of her life.

I left her there, helplessly sucking her finger and gargling cum, sobbing to herself. The shock of having her mind ripped open, and the shamefully aroused fear of what a future might be like where even talking or eating would instantly reduce her to a simpering puddle. I imagine the thought probably upset her just a little.
It happens sometimes in this line of work.
