My roomates are lingering, so I decide to just go in my panties. You can see the glass cup filling up with piss as I piss in my panties and it leaks through. My bladder was full so it's a lot of piss. I keep pushing and fill my panties all the way up. You get a hot view from behind of me squatting over the glass and you get to see how full my panties get. Hope you enjoy!
