Pieds dans les chaussettes, bite dans l'urine, CBT, pipi

Mistress ERA holds a regular session with a slave, sitting on a transparent chair, she moves the slave to a frenzy with the movements of her legs, his cock reddens and pulsates from sharp and strong blows, and when she pisses on him he restrains with the last strength not to end sooner, he can't, until the full session is completed.
