My ultimate fantasy

What would be your most ultimate fantasy scene  even if it is impossible to fulfil, 

I'll start. 

Some time in the future body parts can regenerate. My mistress has me secured spread eagled on her bondage table, she's wearing a strap-on that is the size of a horse cock, it has its own urethra and a tube leading to a sperm bank that has been fill by her other subs in a milking shed, they are constantly being milking while they await the same fate that I am about to endure. 

First thing Mistress does to me is attach some evil nipple clips to my nipple they bite down hard,so hard they can't be pulled free when she attaches rope to them and stretches them up to a hook in the ceiling above me.

The ceiling has a mirror finish so I can see everything my mistress does to me. The pain in my nipples makes me hard as a rock, the two Viagra pills she force fed me also help with that, she wants my erection to be solid the entire time she's getting her pleasure while she plays with my body.

Next she places some silicone rings around each of my testicles separately pulling them apart. Then she injects a full 100ml of cum also from the milking subs into my urethra and bladder, she follows this with a urethral sounding plug, the tip of which is slightly larger than its shaft so it is forced through my prostate and anchors itself in the opening of my bladder. 

Mistress then positions herself between my legs, lubes my ass with another 100ml injection of cum and slowly feeds the strapon into my ass, when she starts to feel some resistance she gets a firm grip on each of my testicles one in each hand and pulls me onto every delicious inch of her strapon not careing how much she has to pull, finally I feel it's tip entry into my stomach and it's balls resting between the cheeks of my ass.

She releases my testicles and picks up a 4 inch long meat skewer and shoves it through one of my testicles then does the same to the other one.

Mistress starts to withdraw her horse cock strapon until just the head is inside my ass, then inserts it all again, repeating this until she can achieve an easy rhythm of fucking my ass with full long stokes, she pauses when it's imbedded all the way in my stomach once more.

Mistress then picks up the leads from her estim unit and connects each lead to each of the meat skewers inbedded in my balls and applies a constant electrical power to them.

At this stage I'm moaning with pleasure and my need to orgasm is fast approaching, however with my cock plugged with the urethral sounding rod it's impossible for me to ejaculated.

She commences to fuck my ass, desperately I want to cum.

Mistress is pounding my ass fast now, still with full length strokes  & she's increasing the power and intensity of the estim.

I can't hold back my orgasm any longer as the estim is at its maximum strength, but I can't ejaculate because of the rod plugged in my cock, so my cum is forced backwards into my bladder, Mistress starts to pump me full of the milking shed cum until my belly is bloated & I look like I'm 9 months pregnant.

Mistress then warns me there will be consequences if I spill a single drop of her cum from my ass as she withdraws her cock and replaces it with a 3 inch diameter butt plug.

Mistress reduced the power to the estim allowing my balls to rest. Mistress then came to my head and asked if I was thirsty, I eagerly replied, yes Mistress, which may be a mistake. 

Mistress then orders me to open my mouth wide, then proceeds to rape my mouth with her horse cock, I could only take half its length when I felt another intense shock to my balls and this time I felt my prostate spasm, the butt plug was also connected to the estim unit. 

I knew the estim was powered on once more. I also knew it wouldn't be long before I reached the point of orgasm again.

As  Mistress continues to rape my mouth and throat she increases the intensity of the estim, but this time it was set to pulse. 

When I reach the point of no return, Mistress sensing my impending orgasm, asked if I was ready to ejaculated my cum, 

I could only nod and moan my garbled yes yes yes please, around her horse cock dildo in my throat.

Mistress then told me she would quench my thirst first and proceeds to pump my already bloated belly with more of the milking shed cum.

Mistress then leaned over my body just as I was about to cum again, I was thinking that this cumshot would also end up in my bladder, but Mistress quickly sliced of my cock around the sounding rod, removing my cock and then the sounding rod. 

My orgasm exploded intensely and Mistress made sure to capture every delicious drop.

When my orgasm was cumming to an end she removed the estim from my balls and then slowly removed the skewers.

The electrical pulses continued to shock my prostate and every so often another spurt of cum shot out of the hole where my cock once was.

Mistress removed her cock from  my mouth, my belly bulge was like I was having triplets.

Mistress once again walked to my feet, and place a strange looking press between my legs and secured my balls to the hard base. Mistress pushed a button and the upper section started moving down. 

In the mirror above me I could see the upper plate had dozens of needles pointing down towards my balls, they slowly started to penetrate them, as the upper plate continued to crush my balls to mush, ball juice and meat squeezing out due to the plates coming to a gap of 5mm, the mush of my balls and the juices they once contained all drained into a container under the baseplate.

Once my balls were completely destroyed Mistress pushes another button and a blade swings down slicing them off at the base.

Mistress sets me free, all except the 3 inch butt plug in my ass which stops me from emptying my cum filled belly.

Mistress then thanks for providing the special ingredients for a very special dinner,  she invites me to situation her dinner table and she the meal she now cooks, she pours two large glasses with fresh warm cum and we sit down to eat & drink, my fried cock and testicles mush marinated in my cum. 

Well Mistress ate, as my belly could not take anything else as it was full of cum. Mistress still ordered me to drink all the warm cum, she reminds me that cum should never be wasted. With my belly so full I could feel the cum settling half way down my throat. 

While Mistress ate I could already feel my cock and balls regenerating to an even larger size than before, we could continue with our scenes another day. 

Mistress said if my cock and balls regenerate to a big enough size to share, she'll invite a few of her friends around to help think of other ways to torture my body next time. She has even said she knows of a transgender Mistress that is hung like a horse that could penetrate my mouth or ass which ever is not being used at the time of ournext scene.

The next morning after a restless sleep Mistress allowed me to remove the butt plug, while straddling a 20 litre drum, ( like Mistress told me the night before, cum should never be wasted), the cum exploded from my loose gaping asshole the humiliation I felt as she stood watching me evacuate all the cum from my loose used ass was immense. 

But I can't control my excitement for when we commence another scene and my brand new cock erects to a thick solid 10 inches and my ball to the size of tennis balls, easily large enough to share with her friends. 

I can't wait.
