This is the 5th chapter in my story, previous chapters can be found in my post history or the comments. Suggestions welcome.
Alex stares down at his beautiful little sister, savouring the moment. His Mom lies naked face down in front of him, literrally fucked into unconsciousness, her sweaty limbs sprawled out, her gaping asshole occasionally farts out a small amount of his cum which drools down over her cunt, pooling on the bedsheet. Over the years he had fucked countless girls and women, but none of his conquests had been as sweet or as brutal as pounding each of his mother’s fuckholes into complete submission, and he realised with startling clarity that every woman he had ever fucked had been a subsitute for his mother, and every girl a substitute for his sister. A large gob of pearly precum forms at the end of his cock, and his sister tries to raise her head to slurp it from him, but instead he pins her head to the bed, forcing her to wait patiently as the dollop of thick cum slowly stretches, finally dropping down into her waiting mouth. Mandy moans and licks her lips, a tiny shudder running through her petite body. A true cumslut, just like her mother.
