My step-mum is being really annoying and wanting to bond. We went on a shopping trip earlier but I'm just giving her attitude. She asks to see the lingerie she got me earlier and I show her reluctantly. As I'm trying my hardest to ignore her, I'm watching the porn she has made on her phone. She gets cross at me and spanks me for looking at it. I ask her of that's all she's got and spank my step-mum back.
