This story started when I was engaged to my wife. We were telling each other about horny things we had done in the past. I had just told her about my sister and I fooling around a couple of times and then she said, "I know what you mean. I used to come home from school so horny. I would go to the bathroom and lay on the floor and get myself off. Sometimes I would cum three or four times. But there was this one time." Her voice drifted off into silence as she remembered the incident.
She had come home from school horny, but her kid brother was unexpectedly in the house so even if she had gone to the bathroom, she would have had to be quiet. Kate likes to make a lot of noise when she cums and uses filthy language too. So anyway, she had caught her brother watching a porn video and told him to turn it off. He had said "Fuck you, you cunt" and Kate had just seen red and went for him. She had slapped him around and told him never to call her that name again. Then, Kate said, "Suddenly the mood changed totally. I had slapped him around pretty good and then all of a sudden my hands were tugging at his zipper and I had his cock in my hand. I dropped to my knees and sucked him, jacking him off at the same time." She told me he had cum right there and then.
The thing is, I would love to have him with us. To be totally honest, I would like to jack him off over his sister. That would be really something. Eventually, I plucked up the courage to tell Kate that. She giggled and told me that anything is possible. But she added that if she does set something up, fair is fair, and I have to find some way of involving my sister at some point. This is going to be real hard as we never did anything like as much or for as long. Still, I may be able to work something out.
