Have a couple of rules & a dare:
- Whenever you are in a toilet that locks, you must strip naked
- Whenever you are getting dressed/changed in your room, it must be done in front of your window, without looking outside
For the dare, it will be again window based - get something you can use as a blindfold, and a stopwatch (your phone should have a stopwatch). Your aim is to stand at your window naked & blindfolded with your tits against the glass for 5 minutes, however you must have nothing to help tell the time whilst blindfolded. Use the stopwatch to keep track of how long you manage.
When you think 5 minutes have passed, you may take off the blindfold & check the stopwatch. If it shows 5+ minutes, you are done! If you stopped early however, you must immediately try again, but aim for one minute longer each time you fail (so 6 minutes on a second attempt, 7 on a third, etc).
You have free choice over time of day to do this, so you can choose how daring you want it to be
