I couldn’t move. I was chained like a dog on the ground, standing on my fours. My knees hurt like hell and my arms were numb from the effort to stand still – every time I tried to change my position at least to relieve partially the numb feeling in my limbs actually was causing more pain.

What make things feel even worse, was the large screen in front of me. The screen was displaying four different cameras which were filming me from different angles. It was much like the scene was cut from an old BDSM movie. Even the lighting. It felt so strange to be able to observe myself in such a vulnerable position. My sister was behind me. Her blank eyes were staring at my butt. Around her waist there was a strap-on belt and an enormous dildo was attached to it. It was so unrealistic, almost like a dream, but somehow, I had to accept that this was the reality.

She grabbed my buttocks and gently spread them. The closest camera showed a view of my ruined asshole. I don’t know how much time exactly has passed since they devoured my rear hole but it still hasn’t healed. The camera zoomed to show a close-up of my blown malfunctioning sphincter and captured the exact moment when the head of the dildo pressed against the newly made entrance.

The head of the dildo disappeared in my rear with easiness. After the treatment I received earlier, my sphincter couldn’t do otherwise, but betray me. Inch after inch, the dildo slowly filled my rectum until I felt the hips of my sister resting against my buttocks. She paused for a second letting me feel how packed with plastic cock are my bowels. Then she gently withdrew until only the tip of the monster remained buried inside of me. She didn’t make me wait long before ramming the whole thing back inside. The intensity of her rhythm she established made me moan.

The cameras captured my expression every time the dildo was reaching the deepest parts of my colon. She continued her torment for what felt like an eternity, but really, she fucked me until my asshole prolapsed once again. Before withdrawing completely, she fucked me slowly for a few minutes letting the cameras capture the pinkish softness of my bowels protruding outside and hugging the destroyer.

She left me like that chained like a piece of fuck meat, immobilized, unable to do anything to help myself. For hours I had to stay in the same uncomfortable position. The pain didn’t let me rest even for a minute and on top of everything on the screen there was only one camera playing for the whole time – zoomed frame with my gaping asshole.

“Do you like your new cunt, slut?” I didn’t hear him entering the room, but there he was. “Oh, I actually forgot that you cannot speak. I guess you are already used to the special mouth gag? Shall I give it a try?”

At the same time as he spoke his last words his crotch was already in front of my face. He unzipped his pants and put his still soft dick inside the hole of my mouth gag. I felt the disgusting taste of his dick filled my mouth. I felt his hardness growing on my tongue until his cock was fully erect. He mercilessly fucked my unwilling mouth. He soon ejaculated. His seed filled my oral cavity and clogged my throat. He held my head, as I tried to breathe, his cock still inserted in my mouth. Unable to do anything else I swallowed. He held me like that for a little while before finally he withdrew from my mouth.

“It seems to me that you are going to be a very capable cock sleeve.” He stated, watching me drool through the hole in the mouth gag.

Next, he walked behind me and a second later I felt cold steel touching the burnt skin around my cunt. He teased me a few times and then inserted the cold steel rod deep in my vagina. When he moved away, in the screen in front of me, I could see the wire starting from the rod vanishing in one of the dark corners of the room.

I didn’t have to wonder for long what was going to happen. I saw that my sister had entered the room at some point without me noticing her appearance. Maybe while Jason was inserting the electric rod in my poor vagina? That didn’t seem important right now, as I noticed that my sister was wearing the same belt as before, but now the dildo has been changed.

The new one was considerably bigger both in length and width. Its head was made from metal with metal bands, built in the shaft, running along to its base. Jason unchained my arms just to tie them behind my back. Then he took a leather bridle, which he attached to the collar around my neck and around my chest, in that way immobilizing my hands completely.

I was not surprised from what followed next. My braindead looking sister positioned herself behind me and inserted the new dildo in my wrecked asshole. She grabbed the bridle and started thrusting in and out of my shit hole. She fucked me mercilessly, going deeper and deeper until after what felt like thousands of thrusts the dildo sank in my rectum to the deepest point possible. I gasped as I felt how my muscles clenched. The dildo in my colon had aligned perfectly with the rod buried in my vagina which caused the rod to produce electric shock. Wave after wave of electricity made my body shake. My sisters cock was still buried in me, when the last wave of electricity faded away. As I was still sobbing and shaking from the electric orgasm, Jason came closer and took a picture of me and my drooling mouth.

A moment later my sister let go of the bridles and unbuckled her belt. She stood up and went away, leaving the dildo still buried in my anus. As my arms were still tied behind my back and I was exhausted from the ordeal, I couldn’t do anything but lay my torso to the ground to take some rest. Jason seemed to like the submissive position I was in and took another picture of me before leaving the room.
