Now masters generally reward obedient slaves in suitable ways. For instance, a particularly well-behaved slave might be rewarded in the following exercise by being allowed a glass of my own pee instead - but it'll take some time for you to earn such priviliges. That doesn't mean your level of obedience will go unnoticed, however.
You should have turned the clothespins on your nipples seven times since you put them on. If you failed to turn them at the correct time every time, drink one glass of water now and set it aside.
Did you fuck up or skip any of the other exercises we've gone through? If so, drink a glass of water - yes, a second one if you failed the clothespins. And if what you fucked up was holding the cock in there for 15 seconds after the first gag, down another glass.
Now there's a chance here I'm going to make you drink your own piss. But unless you've been a disobedient little shit, you at least have a chance of not having to. As soon as you click continue, lower the blindfold over your eyes and mix up the glasses so you don't know which is which. Then pick one up and start drinking it - and as soon as the liquid hits your tongue, take the blindfold off - but keep drinking. Understood?
Do it now.
