This time the fingers were not removed completely, but began to slowing ease in and almost out of my ass, but never withdrawing completely. The stinking that had initially accompanied my three finger invasion began to subside as my ass began to lube under the steady rhythm of the hand fucking my ass. As I was getting used to accommodating the fingers they were spread in my ass, now side by side, instead of stacked, this again brought back the stinging that had been present in the initial stages of being fucked.
The spread fingers started a faster pace, but instead of going straight in and out of my ass, they hand corkscrewed in and out, stretching my hole in all directions. The hand was driving deep into my ever stretching ass, as if they noticed this, whoever was driving their hand into me added the final finger, alongside the other three and continued to twist it into me. They continued to stretch me for an eternity, driving their hand into me until their thumb was pressing onto my balls. The hand was pushed into me as far as it would go and then just held there. Slowly it just rotated, the widest part of it stretching me, slowly rotating first left, then right, keeping the forward pressure up, ensuring that it was as deep as the thumb stop would allow.
The hand was withdrawn and I immediately felt something spread my anus as it attempted to penetrate me, it was well lubricated and with a reasonable amount of pressure, it spread my anus wider and slipped into me, fill the void within. It was large and filled me, but not large enough apparently. I heard the sound of a pump expelling air and the object inside my ass grew, filling me and stretching my anus further, again, the sound of the pump, it was becoming uncomfortably large. My ass involuntarily tried to expel it from within me, but with two more swift inflations this was impossible, I was solidly filled stretched and plugged.
My ass twitched and spasmed around the huge plug that now completely filled me, attempting to expel it from inside me, this went on for a few minutes until my ass became accustomed, or just surrendered to the huge object filling me.
I then felt my hands being detached from my ankles and I was instructed by my Mistress to roll onto my back, I was shocked to hear my Mistresses voice as I was sure that She had left the room, confused I rolled over. My legs were spread out in front of me and pulled flat forcing more pressure onto the huge plug, they were pulled apart and the ankle cuffs fastened to something keeping my legs apart, my wrists were fastened above my head, exposing my chastity covered cock.
The next this I felt was a loop of rope was being looped around my balls, the ends were looped off behind my balls then the ends were pulled down and looped through the ties on my ankles and tied off to each other, pulling my balls hard towards my feet. There was then a sharp stinging in my balls as something struck them, my back arched and the rope pulled on my balls tripling the pain. The crop rained down blows on my balls and inside my thighs; I gritted my teeth through the pain, attempting not to move to make it worse. The heat grew in my balls until I was about to cry out, then it stopped as quickly as it started.
I lay breathing deeply on the floor, trying to catch my breath, I could feel no one around me and all was still, I lay apprehensively, wondering what would happen next, but there was nothing, just stillness, the heat began to subside from my balls and my breathing began to return to normal.
I lay there, waiting, my balls warmed through, my ass full to bursting and my cock straining inside the CB6000, I knew it wasn't over, so I waited...
