I can't say how long the two have toyed with me, to me it feels like hours, but it probably were only minutes. Time and time again the both of them brought me close to a climax, time and time again my Mistress fucked me with her finger and Madame caressed my nipples and pussy lips, only to stop and leave me wiggling and begging, until I was nothing more than a trembling wreck with no other thought left than the desperate wish to cum.
Now I lumber awkwardly behind them while they explore the shop, my pussy pulls and pumps like mad and I have to hold my hands together so they don't get a mind of their own. My thighs are smeared with my juices and my nipples stand out like daggers. They come to a halt in front of a shelf with rubber toys and whisper quietly so I, in my befuddled state, can't understand a word. Madame reaches into a compartment and pulls out a pair of short but wide red rubber hoses which she shows to my Mistress. I wonder what they could be good for, and guessing from her facial expression, it's no different with my Mistress. Madame explains something, and they both grin at me, which makes me nervous.
"Do you think the size fits?" my Mistress asks, and Madame answers her with a nod.
"Maybe a little tight, this ones are B, but a C would be too lose." She swings the rubber item around, its roughly two and a half inches long and has the diameter of my lower arm. "Hold still," she orders me and I press my arms to my sides, "and close your eyes."
I close my eyes and feel her touching my breasts, then a strange, smooth feeling encasing one of my breasts. Then her fingers vanish, and the smooth feeling gets stronger, constricts my breast. Frightened, I open my eyes, but before I notice anything I hear a smacking sound and my breast is in flames. I whimper and close my eyes.
"Silly thing," I hear the biting voice of my Mistress, "not even able to follow a simple command."
My breast pulsates and and feels like it is squeezed through a narrow tube. I start. Tube... hose! I realize what the rubber things are good for, and already the other one closes around my other breast and constricts it. Hands turn me around and push a few steps forward.
"Open your eyes again," my Mistress orders me, "and look at yourself in the mirror."
I do as told and my breath catches in my throat at that sight. The rubber hoses encircle the bases of my breasts like a second skin, squeeze them together so that they are reduced to half their normal thickness, but elongated and pushing out nearly horizontally, while at the front a taut, fist size ball is formed. It looks alien, but at the same time highly erotic. I stare at the picture and am fascinated. Madame giggles contently while my Mistress licks her lips and the skin on my tits get rosier.
We wander further through the shop, and the both of them giggle and gesture like excited young girls while they pull items from the shelves, examine them and put them back. The tension in my breasts gets heavier, it feels as if the rubber is getting tighter and tighter. My Mistress pulls something small, metallic from a shelf. The corners of her mouth lift appreciatively, and it dawns to me that this doesn't bode well for me. The redhead whispers something in her ear, an explanation perhaps, and they laugh.
They begin to caress my breasts, pull at my nipples, and I twitch a bit because it feels so good, but just then my Mistress barks at me to stay motionless. "Close your eyes!" Orders the small redhead, and I close them obediently, while my tits are under electric current and thousand small lightnings run through my nipples. Suddenly, a sharp pain travels through them and my eyes shoot open. My nipples burn like hell and, shocked, I stare at them and have to gather all my concentration to not rip off the gruesome toys they have attached to me.
The metal items are nipple clamps, but not simple ones, but unspeakably insidious torture devices. They consist of a ring with bent jags, about two inches in diameter and with a hole in the middle. The jags point towards my breast and bury themselves deep in the taut skin. Through the holes in the rings they have pulled my nipples, until they reach two evil looking alligator clips which are fixed two inches above the rings and push their teeth deep into my sensitive buds and pull my teats out thin and long.
I grimace with pain and begin to tremble, and my eyes become moist. "Please..." I whimper and know instantly that this was a mistake, the enraged look on the girl's face tells it all. Her hand shoots out and smacks my pussy loudly, sends a gruesome pain through my lower body and makes tears run down my cheeks.
My Mistress watches us interestedly, and I want to throw myself at her feet and beg her to stop this, but then pride grips me. I pull myself together, feel a few loose tears trickle down my face and onto my tits and look at the girl submissively. "I am sorry, Madame, it won't happen again." Uttering those words costs me so much effort, because I know they will only bring on more pain, but at the same time they please my Mistress and promise me unbelievable earth-shaking orgasms in her arms.
The redhead glares at me. "You softie, I would have thought that a slut in heat like you wouldn't start crying at the first little bit of discomfort." She starts walking around me in a circle, furious. "I don't know if I should even bother with you any further. Maybe I should push you back out into the street like you are."
Panic grips me, a look at the face of the girl confirms that she would certainly throw me out naked as I am, and probably without even giving it a second thought. I bite down on my lower lip, but she suddenly grabs my arm roughly and pulls me all through the room. I stumble along awkwardly in my high heels and try not to fall over while my Mistress follows us with measured steps, then I'm suddenly thrown around and loose my balance.
