Played with another guy - Spanking

My playmate Lara confessed that she cant quite take her regular spanking from me because she had already been spanked by another master one day ago. I explained to her that she was my bunny first in line and when she decides to get spanked elsewhere, I will spank her with the same strictness as usual. I get her OTK and spank her bare ass with my hand and hairbrush to finally let her get up just to bend over the trestle for a caning. I will make her lern whos her master. No safeword for her today! There are still marks on her ass. Stupid girl! This one she wont forget. Thats for sure.
