So, this is what sounding is: https://en.wikipedia.org/wiki/Urethral_sounding

And literally one of the first things I said to my friend when I got home from seeing TFA was that I wanted to see Kylo Ren laying out on a bed with his hands restrained, a sounding rod in his dick, and begging and pleading to cum.

So... That.

Bonus points for Kylux or Kylo/Phasma, and even more bonus points if he still cums with it in him even though he shouldn't be able to.
