All Day Pee Play & Despair
This page might not be a lot of fun, but the tease hasn't started anyway and you should be told this, especially if this is your first time doing something like this:
Disclaimer: while the amount of water you'll be drinking will be below danger levels (500ml-750 per hour), water poisoning can be a risk. If you're feeling unwell or feel like you can't drink anymore, don't. If the feeling persists, stop the tease. Don't do this tease while sick either, especially if you have a stomach/bladder infection. A healthy bladder shouldn't get damaged from doing this tease, but don't do it a few days in a row. Also, if you really have to go and it's starting to seriously hurt you, it might be time to let go ;)
There's no shame in quitting to prevent damage to your body, the only shame is in quitting to prevent damage to your ego.
