Sleep Play
Erotic roleplay during which one participant, usually female, lays out on a bed or couch, typically fully clothed, and pretends to be asleep while the other participant, usually male, touches, massages, fondles, and plays with her body while she feigns sleep, eyes closed. Because there is no duty or obligation on her part to react, moan, or please the male participant, her mind is free to receive gentle tactile stimulation and more easily reach orgasm.
She and her boyfriend's favorite sexual activity besides intercourse was sleep play
