Glasses stay on while she plays

Bare floor and a plain wall behind her, with her glasses still on and lingerie across her hips. She spreads her legs wide, reaches between them and works a toy while several more lie on the floor within easy reach. The glasses stay on her face throughout, the lower frame catching what light there is each time she tips her head forward. It ends with her lying back on the floor among the toys, lingerie still on, and the room stays unchanged around her until the end.
