She feeds her patient a little something that triggers a massive, painful erection. The poor creature moans and wails in pain as his cock hardens, but Odette knows no mercy. She spits on his engorged cock and rubs it furiously. She gags him with her hand and stimulates the poor captive cock. She is truly a merciless medical sadist...
