Elena, bound and at Alex's mercy, feels the cold, hard plug press against her asshole. He pushes, inch by inch, until it's fully seated, her asshole gaping obscenely around the base. Alex admires his handiwork, then begins a brutal spanking, his palm striking her vulnerable flesh, leaving it hot and marked. Elena's cries of pain morph into moans of pleasure, her cunt leaking, as she submits completely to her master's will.
