None of mycoworkers new my secret, but I had continued to dress in my off time athome. I had collected a fairly sizable wardrobe and would sometimes d...essup and go out as Mandy on short trips. I had only been with one man in mylife and sex with him had consisted solely of giving him a blow job. Nowback to my story.When we returned to Renee's place we sat and chatted as three girls for acouple of hours. Renee told me all about her plan for mt upcoming date. Ihad a two week vacation starting the. She got over the initial shock Cumming over and over as she tormented her sweet cunt till the count of ten. She laid there covered in sweat as I brought her a big black handled hunting knife with about a 8 blade, again wasted no time as she teased her clit with the very sharp point, until she poked herself and let out a scream that mad her squirt about 3 feet. She flipped the knife around and started plunging the handle in and out of herself as she counted to 30. Ten to go I thought to myself,. He wasn’t ugly, this guy, just mean. Every part of him read meanness, from his squinty-eyed glare to his reddened face as he tried in vain to intimidate me. He was clearly a bully, a lifelong one at that, used to being able to terrify his way into whatever he liked.The man didn’t get far at all before I plunged the knife in and struck a kidney, making him fall down in agony. I pulled it out and slit his throat, showing him mercy at least, more than he would have shown me. We rushed to get his. I was such a freak, and it must have been off-putting for my brother, because he always insisted I stop giving him head shortly after.“Kelly?” I said, licking my lips, enjoying the strange aftertaste that so often appeared after fellating my brother for a while. “Won’t she...”“No,” he said shortly, and I immediately shut my mouth, submissively staring up at him. Thinking was becoming harder for me, the less I slept, and so I’d found it easier to let my brother do the thinking for both of us..
