Slave for Five Days and Nights in Amsterdam Part 5

After finally getting a proper night of sleep the slave as regained energy and strength. This perfectly fits Goddess Kamikatze's plan for the next session. She is determined to make him exhausted again.
She has devised an evil scheme with buttons in different places that randomly need to be pressed to avoid electrical current in the slave's balls. The slave needs to keep his focus on the buttons at all time and keep running to press them to avoid excruciating pain from the electrical current.
While running, the spiked cage presses in his cock and nipple clamps with bells pull his nipples. In the meantime Goddess Kamikatze showcases the new lingerie sets that slave has bought for her during a shopping tour in Amsterdam earlier in the day. She takes her time and tries to distract the slave from pressing the buttons.
Soon the slave is out of breath and starts to miss some of the buttons. With the electrical current going up the slave begs the Mistress to stop.
But Goddess Kamikatze has other plans. After showing all the bras and panties, she wants to enjoy the suffering of the slave longer, and continues the punishment while she makes herself come... very slowly.
By the end the slave is in pain, exhausted, and desperate for the exercise to stop. The Mistress toys with him a bit more until she finally allows him to have a temporary break so he can be ready for what comes next.
