Doorbell time, though you're still not sure how that translates to a clock

The doorbell jars you from your groggy thoughts, and you struggle to sit up. After a couple of failed attempts it occurs to you to take your legs off the arms of the chair and you get up feeling just a little stiff.

"Ku-ming" you yell, the dildo still partway in your mouth. You rip it out, wincing a little as it seems to have dried to your dry lips. "Coming!"

You've no more than dashed out to the top of the stairs when you hear the lock of the door being worked and then the door opening.
