This first experience with a chastity belt had been breath-taking, in a frightening sort of way. This contraption, she reminded herself – this steely metal undergarment, was locked onto her hips. And without the key, she truly, absolutely could not get it off. She had no access to herself at all, no ability to let out any of the frustration she felt, a steel wall erected between her and her own sex that no amount of strength could shift. It was a thought that thrilled her as she cast her mind back to the journals she had read of maidens locked into similar, if not less substantial devices than hers. To remain like this, the way she felt now, for months, if not years on end – how would that feel? If she could not remove the belt… no, the thought didn’t bear thinking about. Marinella knew she could, anyway. She had the key in her hand. All she had to do, right now, was push it gently into the lock… just like that… and twist-

…

She sat bolt up right, stumbling to her feet, as she looked down at the key. She twisted at it again, but nothing happened. It wouldn’t turn.

Marinella’s heart stopped. She rattled at the key, at the lock, twisting it in both directions, turning it over. She kept trying for several minutes, wondering if she’d made some mistake, some obvious error, but it was fruitless; the chastity belt remained firmly locked in place, the key refusing to turn a millimetre.

And with that, Marinella’s chastity truly began.
