Tied up to the medical chair, wearing a chastity cage, you wake up in front of Mistress Euryale, who already has a cruel smile on her face, her shiny boots in your face, and holds a remote control in her graceful latex-gloved hands. She set up her powerful fucking-machine in order to pursue your training - you hope that at least she will allow a release from your cage, but she is in a sadistic mood... You will get alternately penetrated by the fucking-machine, teased and denied with her huge vibrator on your cage, and played with like a pathetic chastity toy, with no other choice than to try all the different settings and speed of the machine for her entertainment...
