Standing stilllike a rabbit caught in the headlights, she listenedfor any more noises. Suddenly it clicked into place in her mind; it was justthe plum...bing, as the house settled for the night.Almost laughing at herself, she quickly made her way tothe small alcove at the head of the stairs, where abedroom door lay open. Concealing herself in shadowsshe hid behind the bookshelf next to the door. Lookingthrough the doorway, she saw her older sister Lisalying still in her bed.As she looked in on her. " She said quietly while looking deep into my eyes.I returned her stare as I replied "Good Morning beautiful." "Are you ready for round two?"

I watched her lick the tip then she opened wide and slide my dick into her mouth all the way down to the base.

I slowly unbuttoned my shorts for her and placed my hands back on the railing.“Good girl,” she said, bending down and kissing me on the cheek. I just smiled as her hand slowly unzipped my zipper. Her hand slowly glided into my shorts and inside my panties. I let out a small moan in anticipation, as her fingers touched just above my clit. “Sh. Sh. No sounds please,” she hushed me.But I was finding it hard as she slowly. She was not surprised that although her mind rebelled at being humiliated by her son and what he was doing, her cunt was responding intensely. She was no longer surprised at all that it was her cunt forcing her, leading her, pushing her along with her son. She wondered what made Brian suddenly act this way with her.Come to think of it, what has made me become this way? she asked herself. Again, she did not know.After bathing, she found herself dressing with unusual care, choosing her clothing.
