“Go and get me the hairbrush,” she said, well actually ordered. I got off the bed and pulled up my panties before grabbing the brush from her dre...ser. Mia had done the same and was sitting on the edge waiting for me. I handed her the square headed brush with its thick round handle. “Bend over my knee then,” she said tapping her thigh. “Don’t spank me too hard,” I spluttered wondering what I had let myself in for. “I won’t,” she promised. It felt really odd bending over her knee, her little. .. right ... OK..." I didn't know what else to say. "See you then." Mmmmmm... schluuup... mmfffff..." and her phone went dead.A few minutes later I could see Juggs walking down the hall toward our stand. She was attracting an enormous amount of attention as she walked past the other stands. People stopped what they were doing and were just staring at her. Some pointed. I could see jaws drop open and almost hear the gasps.Juggs is no stranger to the attention her huge tits attracted. She loves. As I arrived back I expected to see mum and dad out enjoying the sun but there was no sign of them. The car was still there so I assumed they had gone for a walk. However, as I passed their bedroom window, I saw some movement. They hadn't closed the blinds as it was just bushes and trees outside their window. Pure luck meant the angle I was at I could see some of the room. Dad was butt naked and walking around, from what I could make out mum was blindfolded and somehow restrained with her legs. I loved watching her from my bedroom window when she would sunbathe by the pool. Even seeing her walk about the house in hardly any clothes always made a tent in my trousers and now here I was seeing her totally naked for the first time through her shower partition. My clothes were on the floor pooled at my feet and my cock was standing out in front of me wishing to be buried in my sister's pussy.I stepped in behind my sister and as my cock touched her bare arse she turned around and looked.
