I need to improve my pain endurance

"I need to improve my pain endurance, Mistress," you answer.

"Very well, my dear," Rita nods.

She releases you from the stall, and you are taken to the training area at the center of the cargo hold. You are sat down on a metal chair without a back, your legs strapped to the frame. Then without any warning, Rita smacks the uncovered portion of your backside with a whip.

SMACK!!!

You tense your muscles, but you don't make a sound. Everything seems alright now.

You tense your muscles, but you don't make a sound. Everything seems alright now.

SMACK!!!

You tense your muscles, and you almost make a sound. But in the end you are able to hold yourself together.

SMACK!!!

"MMMMMM!!!" You try to hold yourself together, but you yell into your bite gag. As a response, Rita stops the beating.

"You have five minutes to rest. Then we continue," she says.

And you spend the entire day practicing as ordered.
