My g/f and I are quite kinky and from time to time I just love to sit spread legged with my hand inside my knickers whilst watching her stand in front of me in a pair of clear crinkly plastic knickers, hands cuffed behind her back, a leg spreader fitted and waiting for me to say “now,” at which time she will release and pee into her plastic knickers as I bring myself to orgasm.
I have done the same for her, (peed in plastic knickers whilst she masturbates) but I am never tied up.
The sight and sound of her plastic knickers filling is just so erotic, if you have not tried peeing in clear noisy plastic knickers I suggest you do, it will drive your partner wild, but only if you are both into watersports.
