Piss... I'm into piss, and I want to get pissed on all the time.
I also love a good bush (Shout out to my Team Bush brothers on these boards), and Puffy nipples. I have a thing for panties (specifically black) and them being pulled to the side for various sorts of fuckery. Stretching, gaping, and fisting are also pretty tight.
I really have no hangups just so long as there's no dick, shit, or vomit involved. Anything else goes! No urethra bullshit either.. that shit sends chills down my spine.
