Water

I have to agree with Owen. The pain is in the movement through and subsequent contractions of the ureter. After a stone hits the bladder it's a peashooter action through the Urethra. The only way you got that fucker in her mouth is if you were pissing in it. If that was the case the nasty bitch ptobably wouldn't care if you told her you shot a stone in her piss receptacle. Either that or the stone was caught on the side of the Urethra, a much wider passage. This is actually possible with a staghorn stone, but to be caught at that stage of the Urethra, be stuck to the side, a erection would probably be very painful.

I seem to be about 80% low on THC. Perhaps, since it is fryday, I'll soon remedy that.
