Fifty-something brunette in white sheets lies back with her thick thighs parted wide. One hand works between her legs while the other grips the pillow beside her head. Her fingers slide in and out fast, knuckles disappearing between her puffy lips. Back arches off the mattress as she gasps between clenched teeth. The bed creaks under her shifting weight, sheets tangled around her hips. Watching her own fingers disappear inside herself, she bites her lip until it turns white.
