The Obedient Insertion

David taps his phone and the vibration dies, leaving the plug cool and inert in his palm. He sets it on the carpet beside a small bottle of lube and says, 'Lie on your back on the bed, Willow. Insert it yourself—show me you're my good little slut.' She rises on unsteady heels, the cage pressing between her thighs as she climbs onto the mattress and lies back, spreading her knees. The latex dress rucks up around her hips as she takes the plug, slicks it, and guides it to her entrance, her eyes fixed on David's face while she pushes it inside. He watches without moving, his phone still in hand, and when she's seated and breathless, he says, 'Good girl. Now stay just like that until I tell you to move.'
