EVIS-023 - 3-day worn stained panties, perverted old man offers more money to make it dirtier with pleasure

A perverted old man offers to buy a high school girl's panties, which are heavily stained with discharge, urine, and blood from being worn for three days. He makes an even more extreme offer: he'll pay more if she masturbates and stains them further. Desperate for cash, the girl follows his instructions, using her fingers and toys to pleasure herself, rubbing all her discharge and fluids into the fabric.
