Hi everyone , I'm new here too ( couple weeks ) and I've done the Jennifer's Blackmail one ... wow.... I kinda cheated a little bit, which took away from the experience... ( totally my fault ) but even so... wow ... what an amazing script. O.k. so the word "WOW" isn't the best descriptive on Earth...
As for the urine thing ... nope , you do not have to drink it and that wont be cheating the script , it really is a "situational option" so to speak.
On a personal note ... I know that I'll end up getting another working webcam and actually do the whole thing fully and properly... so scary but SOOOOO exciting down to my core.... So eventually.... Like a moth to a flame, I know I'll end up doing it in a moment of sublime weakness.
I highly recommend trying it
