Punishments using personal items?

[Slenderman - Doctor]

A question for the Mistresses and Masters out there...

Have you ever made a slave use a personal item in a punishment?

For example... I'm proud of my DVD collection which I've built up over the past two years. A punishment as a slave could be to orgasm over one of the DVD covers. That's what I mean by "punishments using personal items".

Using slave-related items (hairbrushes, food, BDSM toys etc.) is fine but what about items which the slave holds in high regard?

Or would this be a step too far - an invasion of privacy, so to speak? I mean, some may see it as a clever punishment because it'd make the slave learn their lesson. But others may see it as just plain harsh.

Thoughts?

Hope this makes sense. Just a general question I thought would make a good discussion
