Giantess Step-Sisters & Crystal Cherrie
Crystal Cherrie shares a scene with her step-sister after drinking water. Both grow larger than their step-dad, becoming gigantic and aroused. They tease him with their big asses and demand he worship them. He becomes increasingly smaller until they dominate and use him in doggy-style sex. By the end, he is tiny enough to be placed on her ass as she masturbates to orgasm, then she repeats the act with Crystal Cherrie.
