You could consider so, so many ways to keep yourself busy with your new toys and whatever you may already own.
Do you have computer privacy, the ability to password-protect a document or file? If you do, consider writing and numbering eleven scenarios, real short ones that use your gear, both whatever enema equipment you have plus whatever you buy.
Example, copied from my own such list:
Roll a 3: Yes, sir, yes, sir, three bulbs full. The first two are soapy, each expelled immediately. The third is a rinse, also expelled immediately. Now a plug, lubricated lightly, inserted carefully, and worn for 30 minutes. You may touch yourself during the final five minutes only.
Each scenario describes something you could do in the time you have available with the items you have. When your free time starts, roll two dice--and you have to do whichever scenario your dice total, no matter what.
Or you could write yourself twenty-two, eleven completed in a half hour and eleven that take up to ninety minutes. Or thirty-three, including some long sessions. Then you determine how much time you have, and roll two, four, or six dice.
It's kind of like being your own Dom.
