I like pee, not scat, though I have found it sexy when you touch something while fingering her ass.
Scat seems unsanitary, while pee is just gross. And gross is good.
Word of advice- wash your hand good. Last EMS recert (I'm not an EMT, but I hold the cert for work) I had mentioned that 62% ethyl alcohol does not give multi log inactivation of HIV or Hep (I forget which ones). Basically gelled hand sanitizer isn't good enough by itself.
