Who do you test it on first?
My ex-wife—Sexy version
We still had some paperwork now and then, or we paid the last couple of bills together from that period when we still were a happily married couple. She confided in me in one of those “paperwork meetings” that she missed my big cock. I guess when I look back, I fucked her properly at home, in every hole she had. And on the beach. Or in the train. Literally everywhere now that I remember.
We split in a friendly way, even if she found me with her best BFF in our marital bed. She knew that my sexual overdrive was simply too much to handle for her, so she didn’t make a scene as she saw us. Her married BFF looked up for a moment and said, “Hi!” to her and then continued sucking on my throbbing cock. Seconds later it started pulsating, filling her little cheating mouth with my hot cum.
One day, I was very lucky. I saw on TV this “Storage Hunters” thing and decided to try it as well. I started paying small amounts in the first 2 months as I was bidding, collecting experience, and learning the “how to” DIY version. One day, I showed up at a storage bidding location, and I was the only bidder, so I merely paid their expenses, and that was it.
One of the things I found in that storage was this real-life-size, let’s call it “magic,” guillotine. It was a mere coincidence that I discovered its powers, as I cut for fun a carrot with it, and both pieces fell against each other on the garage floor. As I wanted to pick up the two parts, to my astonishment, it was whole again! I did cut it again, this time holding both ends against each other, and it worked again, making the carrot one solid piece of vegetable again!
This was amazing! I went to the kitchen and took from the fridge a full carton of milk, an avocado, an entire halibut fish, and a chicken I was planning to cook that night so I could test it on (dead) animals too.
It worked each single time!
Now I wanted a live animal, so I dug out a worm in the garden and cut it in two. As I held both parts against each other, the worm wriggled and crawled away!
What’s next?
Try it on a bigger animal.
What about the tip of my left pinkie? Did I have the guts?
I did.
It hurt like hell.
But it worked flawlessly!
By coincidence, as a cut piece of worm fell on the floor against another worm I just had cut, I saw to my amazement that the body parts were exchangeable! I tested many more times, exchanging parts, and I even made a carrot-melon vegetable-fruit. I tested it on two different animals, and soon I had a worm-snail made. So, combining different animals was possible too. Amazing.
I stopped testing and went to have a coffee in the living room to figure out how I could use this machine to my advantage. No clue at first.
I could exchange parts and create new fruits. Or worms. Or bodies. Human parts being exchanged? Big pharma would pay me billions for this!
As my ex showed up that Friday night at my place, we first did the usual paperwork, bill splitting (she would bring cash), and anything that needed to be discussed. But she was very flirty, as if he were a bitch in heat. Did she have her cycle perhaps? Once business was done, I handed her, as usual, her big glass of mojito, and we went to the deck to enjoy the sunset.
“Why do you have a young bull in your backyard?” she asked, as she was caressing my thigh, the drink getting into her head. **** always made her horny.
I gave her a second large mojito, and I told her about my discovery, ignoring her question.
She didn’t believe me for a second until I showed her the video recordings I had made, including the one of me cutting my fingertip off. She looked at my hand and couldn’t see anything, not even a scar.
“Let me give you a live demo!” I enthusiastically offered her, and we walked into my garage. I switched on one light because the overhead door was closed and locked. I had prepared a basket of vegetables for my demo, and after that I would do my pinkie again.
Each demo went flawlessly, even my fingertip. To raise the non-existent bar, I cut off my entire little finger. No problem there, as it was attaching itself to the stump within seconds. Demonstrating the parts exchange went flawlessly each time too. By now I had tested the machine at least 150 times, all tests different from each other.
My ex was amazed. “Let me try my little finger!” and we did. It went as expected, flawlessly.
With her watching, I cut off one of my titties. Flawless. No scar, nothing. I cut off both. No issues.
She was truly amazed and excited! “Cut off both my tits!” She said in a sultry voice.
Was she getting sexually aroused? Did she have a kink for this shit? Or
“OK, let’s do it,” I answered her.
I helped her insert her breasts through the lunette, having them secured as I lowered the upper board and locked the lunette with those big bolts on each side.
“Can you move them?” I asked her. “We want a clean cut.”
My ex tried to pull her titties out; no chance.
“Can you wiggle them?”
The drunk slut tried, zero movement.
“Let me check.” I said, grabbing those erect nipples in between my thumbs and index fingers, rolling them.
She moaned, whispering, “My pussy is wet for you...”
“Ready?” I asked.
“Yes, cut me and fuck me afterwards!” She replied,
“Ready for a new experience?” I asked her again.
“Yes, do it!” She groaned, feeling
The blade cut off both her titties high in one beautiful second, with a lovely metallic whoosh.
I released her from the device and held her titties against her chest, both wonderfully growing back.
“So kinky.” She said, “Can you fuck me now, please?”
“Close your eyes and grab inside my pants,” I told her.
She did, expecting that cock she knew so well. But this time, what she found really surprised her! The cock her hand tried to grab was extremely long! She almost came right there, in her pants.
“What did you do?” She asked in a husky voice. “I love it!”
“Touch my balls.” I simply ordered her.
She did. Something was off. They were too big to be human. The circumference was probably 40 cm (16 in.). She was amazed. She HAD to have them pump my cum inside her! She let go, and as she opened her eyes again, she quickly undressed, throwing her clothes as a heap on the floor, using it as a pillow for her knees. She quickly went on all fours and offered me her shiny wet slit, raising her ass as high as possible in the air.
“Take my cunt, my lover. No condom, just as nature wants us to breed. Fill me with your baby-making cum!” She begged me.
My ex had only touched my new cock and new balls but had not seen them. She was in for a big surprise. I was now positive she was breeding. And after today, she would return each day begging me to breed her.
I lowered my pants and took out my new bull cock. And yes, she was right; the balls of the bull looked gigantic on me. Shortly after they were attached to my body, they warmed up, producing loads of hot, ready bovine seed. Ready to breed anywhere.
My new cock I had borrowed was slender, with a girth of perhaps 2 cm (0.8 in.) but 40 cm (16 in.) long. The young bull's cockhead was a bit rounded and with an elongated shape. It was not meant for pleasure; it had one sole purpose: to inseminate the hole it was fucking and dump that cum as deep as possible.
I aligned the little mushroom against her soppy cunt, pushing the head inside without effort. What my own cock had in girth, I would compensate with depth. I knew that her cervix opening was very small, but maybe I would be successful.
The cock went in easily and very deep. I already had at least 30 cm nestled inside her receptive cunt as I bumped into that famous wall, the last and ultimate hurdle: invading her cervix tunnel. I now started a nice mating cadence, fucking her deep and slow, sometimes pulling all the way back and then hurting her again, as I tried to penetrate her cervix to fill her uterus with my jizz.
She groaned with each push of my super cock, loving the mix of pleasure and pain. As I pushed deeper than before, the pain caused a massive orgasm to run like electrical waves through her entire body, even feeling it deep inside her anus. She was truly shuddering on my cock, but I kept nailing her.
Somehow, it felt as if my new cockhead got even thinner, as if it knew that her tight cervix opening would not accept a larger mushroom. From the breeding arousal, I am now really starting to impale her hard and deep. Her fertile cunt was willingly assisting my drilling and eagerly pushed back against me. She was now lost in a continuous series of orgasms and could only groan, like a true egg-carrying slut.
Her face was drenched in sweat while breathing irregularly, her insemination having the absolute priority over any other body function. I held her slim waist with both hands, making sure she would get my bovine baby seed deep inside her. The view of her pear-shaped ass I was ramming made my new giant balls stiffen up, announcing the seeding. As she groaned again, I pushed even harder, and the cockhead finally entered the cervix tunnel! I felt the head pop into the larger space of the uterus and now started to fuck her against the wall at the very end of it. Left and right from the invading cock tip were the tubes that would carry the bull seed directly to her ovaries, securing a successful breeding.
Her small hand reached under me, cupping my swollen balls, encouraging me to finally make her a belly bulge. The soft caressing helped get me over the edge, and the first massive cum load shot deep inside her breeding organ, filling in one dump both ovaries. The next cum dump almost filled her entire uterus, and the third shot of cum did the rest.
But large balls from bulls carry way more seed than human cunts can hold, and cum loads three and four flooded her entire vagina. After that, my balls kept pumping good healthy animal seed inside her, but it burst out of her again right away, as her fertile cunt was already filled completely. My ex crashed to the floor and kept whimpering softly, having had the best fuck ever. I pulled out my now flaccid bull cock, and her cunt leaked a true river of my white cum on the garage floor.
My job was done. In nine months, she would be calving.
