The next day

You wake up in your cell like every other day. You make a few feeble attempts to reach your penis through the arms of the straitjacket. But it's impossible.

You wait for about an hour, then your trainer walks in.

"Good morning, worm," she says.

"Good morning, Mistress," you mutter in your gag.

You get breakfast through a bowl. In the meantime the bucket that contains what came out of you is switched to another one by a guard.

The trainer instructs you to stand up, and you get twenty hits by her whip. You have to say thank you each time. After that she grabs your shoulder, and you are escorted to today's training session.

Today you receive endurance training. Most of the day spent by being tied in place and mercilessly whipped by your trainer.

By the evening you are escorted back. Your trainer fucks you in the ass with her strapon one more time. After that you receive dinner from a bowl, and the bucket that contains what came out of you is switched to another one by a guard.

"Good night, worm," your trainer says.

"Good night, Mistress," you mutter in your gag as she leaves.
