“You really are a slut, aren’t you?” she asked while she held her skirt up so I could use both hands to slide her panties down. “Yes, ma’am... a cum-slut.” I was surprised when I saw that her pubic hair was trimmed neatly, with a thin layer covering her labia and a thicker patch shaved into an upside down triangle pointing down at the top of her slit. I had always thought of her as a prude, but it was obvious now that she was a bit of a slut herself. Her pussy was still a little wet from her. The case to be prosecuted with the missing evidence had to be dropped and Gil Grissom was told to let Catharine go from the CSI force.In his very matter-of-fact, rational approach that Catharine knew so well, Grissom told her she was fired from CSI "with prejudice", meaning not only was she out of a job there in Las Vegas but she'd never get a job in a CSI anywhere else in the country because of the "with prejudice" tag.What was she going to do to support herself, Catharine asked as she emptied. It was close to the evening and I heard the shower stop. I crept up to the door of my mother’s bedroom which she always had unlocked. I was in luck; the door was ajar, and I just got there in time to see the towel drop from her body.Mom looked fantastic. Her breasts were large and soft, and I watched them bounce as the towel fell. She was still quite fit and had a flat, toned belly and a wonderful round ass. I could not help but get hard from looking at her and pulled down my pants to play with. I pulled of my nighty and rubbed my pussy right there in front of Sally.Sally reached down and attached a chain belt to the ring on my collar and pulled my face into her pussy. She gripped my leash with one hand and held a fist full of my hair with the other. I was being firmly guided as Sally came to her own orgasm.After a refreshing shower Sally asked me if I would be wearing any clothes during the experiment. I told her that normally, I would not wear any clothes except for flesh colored.
