This reminds me of a story called runaway experiment on a different site

Sounds like something I'd be interested in seeing. Link?

I, for one, am intrested in a M/tentacle story/chapter.

So, you weren't a writer till you put the mask on
But for real; color me interested

It's not like she'll bring it home, planted in her basement, and invite her friends over to join her.

This. We need to see this.
Also this story is amazingly well written for, as you put it, a first attempt.

First attempt at clop. I've written before. Just not here.

A first attempt nonetheless.

This was very well done especially for your first foray into clop. I especially enjoyed the aphrodisiac/hypnosis part. There's something about
Twilight completely giving herself to the plant that really gets me going. Great work and I look forward to more.

This was pretty good for your first clip fic. 👍🏻👍🏻😃 keep it up :3

This was a amazing first attempt, I look forward to the second chapter!

next chapter please

Ah yes the infamous relative of the Venus flytrap, the (in)Uranus pony trap

On a reread this time, this was just as good as the first time I read it.

giving the tentacle i her marehood

in her marehood

bit off the ground No sooner than

bit off the ground. No sooner than

As she drew closer and closer, stepping over the vines that extended from the flower, the trickle of her essence coming from her marehood slowly grew, until she was dripping. And as she moved, the vines on the ground, attached to the walls, and hanging from the ceiling, stirred.

I have read enough fanfics to know where this is going...

Twilight sighed around the tentacle in her mouth. Was there nothing this plant wouldn’t do for her? First, it led her to this fountain of ambrosia, then it fed her and protected her, and now, it was going to satisfy her needs!

Well, it's obviously a nice plant!
(Suggestion:I would use "Wasn't there anything" instead of "Was there nothing".)

Yup, that's literally another story. (Assuming we are thinking about the same.)

The thought had occurred to her that maybe if she just walked

moving behind her and the tentacle

new heights of pleasure she was reaching.

Came back to find this 7 years later because I loved this fic. I'd love to be taken care of by a plant <3
