Is this poop fetish normal?

I have this fetish where i am very much aroused at the thought of my girlfriend dying from not being able to take a shit! She is in her mid 20's, athletic with a round butt.

It would turn me on to no end to take her deep in the woods, tie her up with extra thick rope, and then jam a massive butt plug up into her anus so she never again was able to have another bowel movement.

It'd be so arousing to watch her scream in pain as her feces keep building up inside of her, day after day, knowing that she will eventually die from never being able to get rid of her feces.

The thought of her feeling absolute agony from her shit being forcefully held in really arouses me. As she is tied up deep in the woods with me, eventually, after enough time passed, her feces would start rotting away at their intestines....

After a while longer (several weeks maybe?) the amount of shit inside of her would cause her intestines to actually explode, sending several weeks worth of her feces into her abdomen and bloodstream.

At this point, her organs would start to become poisoned, eventually causing all her organs to fail, one after another.

All the while I'm forcing her to hold back their shit, i torture her even more by showing her video of other people shitting while she can't of course, which makes her even more miserable.

Eventually enough time would pass where she would have her intestines completely destroyed from not being able to have a bowel movement. Soon she would actually DIE from being poisoned by her feces, which turns me on to no end!!!

Being that my girlfriend is young and athletic, Is it normal for me to be aroused at the thought her dying slowly and painfully from not being able to shit?

Please let me know. Thanks
