Loved them!
I haven't seen a lot of the NTR themed stories, so The Vortex was a welcome breath of fresh air and by far my favorite. I like that you gave the relationship moment at the beginning time to breathe and didn't just rush straight towards the MC portion because it nicely established the stakes of what was being manipulated, lost, and gained for the rest of the short.
I will also second hypfan's comment that including the slight hint of a last fading resistance moment AFTER the MC was done was great - chef's kiss! I feel like many productions go that once someone is whammied, that's it. Done, and the character overall becomes sort of flat, and it's just about the MCer just putting the person through the rest of the script. That's the ultimate point of course in a lot of these stories (and don't get me wrong personally that's why I'm here for MC stories at the end of the day) but I really appreciated that you included the 'last gasp' as you put it to really drive home the NTR theme.
Hope you're inspired to keep making more!
