Not good, but she'll get there

The second you heard Tracy's car pull out of the driveway you whip out your phone and opened the app to control the vibrator currently buried in her pussy. The app allowed you to control the strength of the vibrations on a scale of 1 to 10. You decide to ease her into her training, seeing as she had to last the whole day, and set the vibrator to just 1 on the scale. That'd do for now and besides, you had to get ready to head to work yourself.

Once you had settled into work, you decided to start having some fun with Tracy . You knew she would be in a class right now which meant it was the perfect time to start toying with her. You slowly start turning up the intensity, working your way up to a 5 over the next few minutes. You were having fun thinking of your little slut squirming and potentially letting slip a couple moans as she took her class through their warm-up. You decide to play it slow and drop her back down to a 3, she did have to last the entire day after all. Over the course of your morning you played around occasionally in between drafting emails and taking meetings, working your way up as high as an 8. It wasn't till around mid-day that you finally received a text message from Tracy , which was strange because she should be teaching a class right now.

She also attached a nice selfie of her tits out, to make up for her failings.

You took it easy for the rest of the day, for the most part. It wasn't until you knew Tracy would be in her final class of the day that you decided to really test her. You slowly worked your way up from the 2 you had her resting on all the way up to a 10 and held for a whole minute. Just as you started lowering her back down, happy with her performance, you received another set of messages.

Of course, you hadn't really expected her to be able to control herself very well, especially not on the first day. However, given how masochistic Tracy was, any punishment you could come up with would really be a reward for her. You'd have to think something up later, for now the idea of her coming home with a self-afflicted pink pussy and tits was enough.
