She thinks about Him.

Her fingers set to work eagerly at her cunt. She pawed it with an eagerness like she'd just spent hours watching porn. Her body twitched, and sultry involuntary moans slipped from her lips. Her body twitched and spasmed every time her fingers brushed against her sensitive clit. A sensitivity heightened by days and perhaps even weeks of orgasm denial that her Master had set her too.

He was in her thoughts as she touched. He consumed her thoughts. She was always naked, with a chain (~ownership~) running from her sensitive neck up to him. She could see his face, but never would have been able to describe it. It consumed her, watched her. It made her feel small. It made her feel horny. She had a pathetic spasm on the bed.

She'd only been touching for under a minute, but she already felt the edge coming. Her mind battled. She'd never edged in her old life. If she just sped up a little bit she'd be able to cum in seconds. With how badly her clit was throbbing it would be a sweet mercy. Then an image flashed in her head. His face. Watching her. The chain running from up her neck. Her hand stopped involuntarily. She couldn't help it. All Anna could do was lay in bed, desperately thrusting her dripping pussy in the air, as though if were fucking some invisible phantom cock. But, it didn't matter. She couldn't will herself to bring her hands back, or to even rub against the bed frame like some kind of heated animal.

Anna sighed and brushed her hand against her collar. Pets can't decide for themselves when they cum.
