Thanks for the comments. I'm currently very invested in one of my other stories in the R18 section so haven't really considered this one. I had assumed there was no interest in it. (In fact, I had almost completely forgot about it)
The story was intended to lead into a more sexual version of the film 'Nerve' (A film I thought had potential but really went downhill) but I thought nobody wanted to read it.
I will consider coming back to it in the future though if people want me to.
