Mistress Valentina wanted her chastity slave to wear a dick lock but he did not want. She was pissed as what she wanted him to do was not optional and it was not up for debate. When he did not do it, she felt that it was up to her to punish him. She did so using her chastity device which he had to wear for a month as opposed to a week that she had wanted him to wear it earlier.
Mistress Valentina had a perverted neighbor and she felt that he needed to wear a chastity device and that it would do him a lot of good. So the mistress had him wear a chastity device whose key she had hidden. He wore it as he did not know what it was and he had assumed that it was for fun. He later realized what it was and he regretted it.
