Anfisa's wearing super tight, grey business trousers, which have high tension when she sits down. That's exactly what she's up to, because she wants to cause the bitch beneath her ass the most intolerably pain she can. She glued her to the stool with some adhesive tape so she can't flee and sits down on her whole body with her full weight. Then she stars to wiggle her sexy butt on the stool to crush all of her bones! That's the treatment this bitch deserves!
