An older man, his hair graying at the temples, sits on a toilet, pants around his ankles. He looks up as a young twink enters the stall, a wicked grin on his face. 'I've got something for you, grandpa,' the twink says, holding up a pair of white panties. He drops them into the toilet, now filthy with the old man's piss. 'Put them on,' the twink commands, his voice laced with dominance. The old man, his cock twitching at the taboo, complies. The twink watches, his own cock hard, as the old man pulls the piss-soaked panties up his legs, his wrinkled cock and balls now encased in the damp fabric.
