Hanged upside down, Mistress Euryale's sub can only witness her preparing a stainless steel sound in front of him, applying slowly some lube on the round tip and along the long shaft of the device. Holding firmly his cock and balls in her gloved hands, Euryale penetrates his cock-hole with the sound. He starts to scream right away, as his urethra gets fucked and stretched deeper and deeper. Euryale wants to increase the size of the sound and picks a bigger one, then the biggest, one after another. Her sub can't stop whining pathetically while Euryale digs deep and fast into his urethra. It doesn't stop him from dripping everywhere... After this entertaining cock torment, she grabs his two little balls, squeeze them into her hands, and starts swinging his body around by pulling on them, ordering him to kiss her legs and feet at the same time.
