I have fairly limited supplies, but I have a few nights alone and I'm looking for a nice, long, but simple scenario. If it helps, I'm into a little bit of pet play on the side, even though my master is away.
hmmm, a bit hard to answer such a general question.
Try to sleep in self-bondage (not too tight, not too arousing).
Take your dinner in a tray on the floor, best with your arms tied behind your back.
Wear some (harmless) pet-accessories for sleeping and try not to touch yourself.
Ask your master for tasks.
