Rape her right then and there
From Create Your Own Story
You decide you want her right now, so you get to work and make sure that she cannot cry out or move. Julia is lying face-down on her stomach. You tie her hands and legs to the bedposts so she cannot move. Then you carefully tape her mouth shut. You consider blindfolding her, but you decide you want to see the look of terror in her eyes when you are raping her.
You quietly pull down her pajama pants. She is wearing Jesus panties. You slowly remove her panties so her pussy and ass are exposed.
Your cock is about ready to explode, so you take off your pants and underwear. Your 7" cock is throbbing in your hand, slowly growing larger and larger as you take in Julia's ass in all of its glory. Thankfully, you inherited a good cock size - Something that will make your sister squeal with pain.
Which hole do you take first?
