Well that got pretty brutal! I don't think Rebecca is going to have to worry about Richard anymore. Though I don't think Beth is going to be forgiving their giantess daughter anytime soon either. Unfortunately for Beth, she's still only a few inches tall still so what she thinks doesn't really matter.
Usually all of my content is soft vore so this scene is quite a change. I guess Rebecca just really wanted to make sure her father wouldn't be in her way any more.
