By teasing the men in the house, my sister finally provoked a reaction from some of them. The first was Uncle Paolo, who told her that since she was acting like a child, she should be punished as such. He joined her in our room and, in front of me, pulled down her panties and put her on his lap for a generous spanking. In that position, I could see the swollen lips of her pussy and her buttocks, which, with each spank, were becoming increasingly red. I sat on my bed watching, my cock hard, and when the punishment was over and she stood up, I realized from the swelling of my uncle's crotch that I wasn't the only one who had been turned on.
