She uses a hairbrush

Yvonne grabbed her hairbrush from the bedside table, and brought it down on her The smack was much louder than before, although still dull, but what mattered was the feeling, and it felt amazing. Which is to say, it hurt quite a lot. She spent a good while smacking herself with the hairbrush, and when she decided she'd had enough, she felt very satisfied, as good as she did after her first spanking.

However, she soon found a slight problem. Even though she had spanked herself through her skirt, her buttocks were quite tender, and her panties felt like they were digging in and rubbing with every movement she made. Unlike the spanking, she didn't care for this pain at all.
