my step dad caught me and my sister smoking weed in her bedroom. He promised not to tell mommy as long as my sister let him fuck her ass, while I sit there and watch.
we agreed, but my sister kept moaning and grunting as his huge cock pushed her shit in. her little toes curled as waves of pleasure & pain came over her.
I was powerless. all i could do was watch as he covered her mouth so mommy wouldn’t hear her.
