My Stepmom is an Elastic Villainess

The front door closed with a loud clank as my dad left for his business trip, a deathly silence settled over the house as neither of us said a word. My stepmom was standing by the window, watching as my dad pulled out of the mansions driveway and slowly disappeared into the distance. A feeling of dread settled in my gut as I just stood there watching the back of my Stepmoms head as she looked intently at the retreating car. Her black hair was set in a bob cut that barely reached her bare shoulders. She was dressed in a tight fitting red sundress that showed way too much cleavage, I swear she always leaned forward when talking to me just to flaunt her chest and make me feel uncomfortable. I saw her lean away from the window sill, tilting her hips slightly as she straightened up, the movement drew my attention down to her beautiful heart shaped ass.

"Do you like it"

Her voice shocked me out of my stupor making me looked up. To find she was staring right at me, but.. her body was still facing forwards, no it was her head that was facing backwards. I could see her neck had a twist in it like she had literally twisted it around 180 degrees. What the hell, I gasped and stumbled backwards, I was right she was a freak, I was not crazy when I saw her stretch before. Getting a hold of myself I noticed that her body was wobbling weirdly, making strange gooey sounds, the back of her sundress was growing two bumps, which I quickly realized where two large breasts! Her body was literally inverting with her back becoming her front. Her grin grew sharper and she let out a laugh that made the hair on the back of my neck stand up. She started walking towards me, swinging her hips with every step.

"I think its time you and me had some proper bonding time son"

Not being able to take this craziness any longer I decide to...
