A solo jerk session turns into a cum-soaked panty fantasy. The performer, his cock rock hard, takes in the sight of the stripy panties, imagining the owner's wet, eager pussy hidden beneath. He strokes his shaft, his grip tight, his rhythm steady. His mind's eye sees the panties clinging to her curves, the gusset damp with her arousal. As he finally lets go, his cock pulses, sending rope after rope of cum onto the panties, painting them with his desire, claiming them as his own.
