I gotta agree with the pee sayers! If it was sweat, I would think that wife beater would be almost see-thru or at the very least have some visible signs of sweat. Many people do sweat badly between their legs but if that was the case I think you would see more "sweat" between the ass, which is clearly dry in these photos. Nope, I'm pretty confident it's pee, I've shot some girls peeing in their pants before and thats exactly what it looks like. Sometimes it does trickle down the leg, but only if they've been holding it for a while.
Wait....maybe she's a squirter, who just gets excited by performing in front of crowds
