Your step-Sister Anna is due home from a trip today. So you plan to hide from her and give her a fright. She doesn't seem to care you are not home so you watch her. You're step-Mom keeps calling asking where you are but Anna does not care, she wont look for you.  She goes through to her bedroom to change, wow what a view, her gigantic ass is even bigger when your one inch tall. Her clothes nearly crush you, close call! You follow her to the bathroom and accidently fall in the sink whilst she is brushing her teeth. EWWWWWW she just spat on you. Clambering in to the bathtub, you catch her showering. What a view, her curves are so hot your tiny dick is throbbing. Just when you start to relax from the edge, she knocks you in. You go speeding fast towards the drain. Luckily you cling on to the edge.  You make it back to her bedroom where, omg you can't believe it, she is playing with herself. You get closer for a better look, leaving on her vibrator. She grabs it and before you cant blink, your face is smooshed up in her pussy. She is really wet and really enjoying it. You manage to break free but fall into her pussy lips where she stuffs you inside her with her toy. The last thing you hear is your step-Sister cumming hard.
