My son has been sneaking and looking in my underwear drawer, and to get back at him I have decided to piss in his underwear, dry them out, and then send him this video of me doing it the next day while hes wearing them to school. You will see me in his underwear in the video and then I will piss a full bladder and so the entire pair up to the waistband. I will then take the puppy pad underneath me and rub one out on the underwear to make sure to get as much urine on them as possible. I will dry them out and he will be wearing them at school while watching this video as I send it to him on his lunch break the next day. You can even see his skid marks barely coming through from a stain in the crotch as I am wearing them to piss in them.
