She leans over and tells me the circuit has reached 50% power and I cry and scream with renewd vigor. Now she is really getting off on it, thrusting with violent force and spanking the button on my ass with all of her strength every tenth stroke or so. My screaming turns to crying and then sobbing and then screaming again. I've tried to count the spanks to know how far it has turned up and how far left to go but I cant keep track. I'm panicking now, I cant breath fast enough or scream loud enough to get away from the pain. She's shouting, "yes, yes" with each penetration. Then with one more slap on my ass the pain goes beyond anything I've ever known or imagined. I start to make a mewling sound as my mind loses all thought. I'm not even a real person any more, just a biological receptacle for pain. I couldn't come up with a safe word even if there was one. She is truly evil and clearly has no intention of stopping. She is an evil sex kitten lapping up my pain like it was cream. My vision is going into a tunnel. The pain is so strong it is like a deafening noise in my head. Vague distant sounds of her laughing with glee reach my ears and I don't even understand what it means as I slip into the blackness.
She sees my head sag and go silent and checks the readout on a heart rate monitor. Then she examines the probe for any signs of bleeding but everything looks good. With a final thrust all the way she leans over my back and caresses my neck whispering softly into my ear, "so, how do you like it now little boy? have you finally had your fill? too bad if you have because there is soooo much more to come." She smiles and hugs me for a bit basking in the thought of all that fire and pain flooding into my rectum and feeling my body against hers mindlessly spasming to the endless torture. Maybe just one more smack to turn it up again and see what happens but there is no change, just a body; limp yet vibrating with tension.
After a short while she turns it off and pulls out. She admires my sweat-covered unconscious body for a bit, proud of what she's done to me. Then, she walks around in front and snaps some smelling salts under my nose. I jerk awake and scream again briefly and sag my head back down. She places her hands gently on my cheeks and lifts my head up to face her. I come to focus and remember where I am and what is going on. I start to speak and she touches my lips gently and says, "shhhhhhhh it's OK now the first session is over and you were wonderful." She takes a hydration straw and places it in my slack mouth and says to drink up for strength. "Don't you worry about a thing, you just rest right there for a minute or two and then we'll start again. That was a nice introduction but the next round will be much worse" She lets go and my head sags again as she walks away with a chuckle.
After an unknown passage of time I hear her calling my name again and I snap back to awareness. Behind me, she is caressing my buttocks gently and marveling at the lack of any visible injury. She reaches into the bag and selects a larger strap-on that is 10 inches long and 3 inches in diameter. Unlike the first probe, this one has four electrical contacts. Two are 4 inches long and 1 inch wide starting from the base and the other two are 1/2 inch square and positioned close to the base so as to touch the sphincter at the moment of full penetration. There is a contact switch designed to detect that and redirect the shock from the larger contacts to the smaller ones.
She has also gotten out a small bottle containing a 1.5 million scoville unit hot sauce that is more powerful than many self-defense sprays. Careful not to spill any or get it on her hands, she places the tip of the bottle up to a reservoir in the back of the strap-on. She squeezes an ounce or two into the hole and plugs it up with a cork connected to a short thin rubber hose. The hose leads to a squeeze bulb that will cause a continuous stream of sauce to squirt to the surface of the probe via about a dozen tiny vent holes.
At last she mounts the new instrument of torture into the harness and in one single thrust, impales me and holds it there for a few seconds. I gasp in shock from the violation but shudder in dread and start to cry over what is going to happen next and the finality of it all. The sight of tears rolling down my face is like a splash of gasoline into her fiery desire.
She smiles contentedly and turns on the shock source again. This round, she doesn't waste any time with a slow increase and starts off with a mad frenzy of vicious thrusting and smacks the contact switch on my ass with every single stroke ramping the shock level up very fast. In mere seconds, the shock has got me screaming and struggling again. So far she has stopped just short of full penetration on each stroke but finally decides to jam one fully and firmly in. She holds it there for a few seconds activating contact switch redirecting the shock to the smaller contacts on the sphincter. The same amount of shock delivered via the smaller contacts instantly doubles the pain triggering a single continuous scream lasting until my face turns red and all of my breath is gone. She pulls out a bit and renews the thrusting with brief pauses at each moment of full penetration to hear my screaming flip from simple agony to inhuman howling each time.
After a few more minutes of this the shock level is up to 70% and she decides to take it to the next level and squeezes the bulb a few times instantly wetting the surface of the probe with liquid fire. It is a searing ungodly burning that I know can't be possibly undone with a simple off switch. This is going to increase into a massive burn that hurts for over 30 minutes no matter what happens. The muscle spasms from the shock only intensify the pain from the hot sauce.
In a flash of clear thought amidst the chaos it finally hits me how unstoppable this situation is and how long the night is going to be. My only remaining role is to suffer and she isn't going to stop until every last scream and tear is taken from me ... and maybe not even then.
