Master and I have recently started a new routine when I spend the night: as he brushes his teeth and futzes around, I make the bed. When I'm done, I strip down (I normally sleep in the nude) and curl up in my kitty-corner next to the bed and wait for Master to arrive.
He turns off the light and climbs into bed, and I ask if I can climb in too. He sometimes says "yes" right away, but usually he says "no" or "not yet." Then I curl up in my kitty corner while he scritches my head and he'll ask me a few questions - "Have you been a good girl today?" "Why do you like being my kitten?" - stuff like that. After talking for a few minutes, he lets me into bed, and we snuggle. ^_^
