I want to describe the action of lithely and quickly pulling a satin pillow out of (away from?) underneath someone’s knee pit — This person is sitting in bed and the pillow is placed underneath her leg (the back of her knee, to be percise). It’s silky pillow against smooth skin so it doesn’t take much force to do that.
What word or phrase will possibly best describe it?
How does “draw a pillow out of underneath her knee pit” sound?
Hope someone can give a few examples of their suggestion! Thanks! (:
