Spanking But Not To Hard, Wife Bruises Easily

My wife bruises very easily. Hit a filing cabinet or desk corner with some force at work and she will have a 2 to 3 inch bruise. For me and I think most other people it will hurt for a while and that is it.

We have been erotically spanking for several months but something has come up and I want to go a little harder. Not what I think would be considered a disciplinary spanking but one where she knows she has been spanked. Good pink bottom with a little sting. I think a brush or paddle could bruise her. I don’t want to bruise her.

Has anyone else here, had a spanking relationship with someone that bruises easily? How hard/long can you go before you caused a bruise? Are there techniques that allow you to go harder and not cause a bruise where one would be produced otherwise like location on the cheek, massaging, tempo, etc?

 

Thanks,
Things went well. No brusing.
I am the one not wanting to mark her. At least not at this stage. Down the road, who knows??
