"Sleepwalking"?

The officer's face did not seemed convinced. After a few moment's of watching her cum herself senseless, the choker released her, leaving her the task of dealing with the police. The only excuse she'd been able to come up with was that she'd been sleepwalking. Cara was having trouble thinking clearly, her cheeks still red, (and pants still soaked through) with sexual exertion.

"And what about the chat room message. Were you looking at porn on your computer while sleepwalking too?"

Cara shrugged, trying to look innocent with sex sweat still on her brow.

"I guess so. I don't have any memory of it."

She thought of asking the officers about the choker as they spoke to each other quietly. It seemed to know what she was thinking, and warned her with a single lash to the ass. She jumped and squeaked. The officer's looked at her strangely. One came over to talk to her.

"Look Miss, try not to "sleep walk" or whatever you were doing again. Have a nice day."

The officer's left. Cara breathed a sigh of relief as she locked the door. It was cut short as an invisible chain jerked her back to her room.

"Please, no..." she begged as she was strapped spread eagle to her bed.

"Now my pet, some excersize before bed."

The dildos pumped in and out furiously, her nipples pinched, whipped, and stroked. They continued until she passed out, a sweaty, orgasmic lump on her bed.
