Iris along with her partner Jase post on Fetlife and have a dom/sub vibe going on. There are numerous videos on Manyvids showing off.
I have one video which I've posted below - this was posted on Manyvids before they were forced to remove it.
Pint of Piss
"We had so much fun filming this custom where it was requested that I drink a cup of Jase's piss, have him make me spit it back up, and then swallow it again. I love being a thirsty, filthy whore. Cheers!"
