An ass used much like a pillow. You lay or sleep upon it, this requires your butt pillow to be on his or her stomach and preferably with no clothing to detract from the warm softness of a butt pillow.
"Baby I'm so tired, roll over and gimme some butt pillow to sleep on"

"Alright honey"

And she proceeded to roll over onto her stomach, and pulled her pants and panties down to her knees. Just enough to expose that supple and soft butt pillow.

With arms tucked under her I laid my head on the left cheek and proceeded to drift off to sleep.
