The rain made the weather cool so I decided to go shirtless. I hopped into bed, the thought of kissing my sister plaguing me. What if she tells mom an...d dad? Ugh, I'm fucked. I felt disgusted with myself, like I contracted some horrible disease, but I couldn't deny the feelings she gave me. I sat battling my conscience when she finally came out the bathroom. I pretended to be asleep as I watched her go to her suitcase. She was still naked, the towel wrapped around her head. My cock sprung up. Her small, but full breasts sat firmly on her chest, crowned with erect, pink nipples. Her ribs collapsed sensuously to her small waist with her tiny navel centered in her flat belly. The small patch of dark pubic hair no longer hid her swollen labia from view. Her legs were slightly open, and her musky smell only served to further harden Mikes already rock-hard cock. Heather looked into Mikes dark eyes and instinctively raised her arms in invitation. Spread your legs, he commanded, I want to. I felt myself being drawn in to her remonstrations until I cracked and got up from my perch on the edge of the sofa.I still don't really know why I did it, a little bit in order to test her but probably honestly more to induce the reaction that I was sure was coming.I got up and went over to the kitchen surface in plain view of the door. I took a knife from the board upon which I had been chopping onions and pricked the end of my finger. A little ball of blood welled up.Mircala went quiet and. Jason tickled me under the chin and started to leave the room. ‘By the way, I didn’t know you slept naked. I like that. Oh, and you might want to brush your teeth.’I winced, covering my mouth with my hand.‘You’re supposed to get up now. Mum and Dad sent me to come get you because they’ve started planning our family vacation and want your input. They’re waiting so you’d better be there soon.’With a final smile, he left, closing the door.My pussy was itchy. Very, very itchy. Like I wanted him to.
