hit her! then see how she is. if she doesn't improve use and objet and beat her for like 7 mins (no longer because any longer is "abuse")
you could also tie her up with some rope and duct tape (although i hear thats in short supply) just use packageing tape. so leave her there for a weak or so. get her really dehydrated then force and object in her anal and vagina at the same time (but not the same object) use different shapes. try a square peg for the anus and hexigon shaped peg for the vag. she won't be be able to lubricate itself due to lack of hydration. watch her bleed and then untie her. if she isn't straighted out by then i would dump her. she doesn't seem like a girl i would want to be in a relationship with
