Slave sent for 10 years in Sahara

Princess Hannah had slaves work for her in castle. One slave accidently left dirt spot while cleaning Hannah's shoes....which resulted in her outburst of fury and anger from princess Hannah.
She immediatly run to her daddy king and telled lies about that slave how he tried to hit her and she barely escaped.
King immediatly sentenced this slave to death in Sahara quarry. He chained that slave and sent him to Sahara to work until his death.

While poor slave was chained and gone to Sahara, Hannah made puppy eyes and asked her daddy if he can get remote shock collar while there. King cant say no to his little princess...
Bad thing is that Sahara is in different time zone than place where Hannah lives, so when slave works in quarry Hannah sleeps. When his workshift is over and he gets time to rest Hannah wakes up and starts to play shocking games.

His only hopes are that Hannah will sleep longer so he can have rest, or that she gets bored shocking him.......but 16 years old spoiled bratty teenage girl never gets bored and is full of energy.
She can push buttons all day while slave recives bursts of electricty while wriggling, squirming and drenching in sweat.
