Wakes up next morning, locked in the belt

Next morning felt like waking up from a nightmare. With all the vivid dreaming Mackenzie didn't get a good rest, and the morning found her tired and dizzy, let alone horny as hell. She reached out to the nightstand, opened the drawer where she kept her toys, and let her other hand slip under the blanket, between her legs.

Her dizziness evaporated instantaneously when her fingers touched metal and she stood up right away, suddenly aware of her sore ass. "Fuck!" she cursed loudly as she pulled the blanket away, looking down. And there it was, snug but oddly comfortable, the **** instrument that Rachel had locked her in: the chastity belt.

Mackenzie's heart sank as she remembered Saturday's events and the memory of being helpless and humiliated filled her with embarrassment. Even worse, she felt aroused. Instinctively she reached out to rub her perky nipples, but that put her even more at a disadvantage. It only made her feel more aroused, and more conscious of her inability to do anything about it.

She tried to pull at the metal, to tug in a direction or another, or to slide her fingers in any orifice or gap she could find. It wasted the better part of half an hour just to confirm that none of these things helped. She was locked into the belt securely, and only Marianne and Rachel had the keys.

This started to become a bigger problem than she thought. She was aroused, being locked like this aroused her further, and she was helpless to do anything about it. Rachel said she'd have to wait a week. Right now this felt like an eternity.
