At a certain moment you experience some kind of terrible heat/electric shock. You have been just burned to get your sister muscle move! WOW.
You are being sucked again - this time the blood around you looks more dark, maybe blue. You are in her vein.
You "see" that this time you start moving back upwards. You are passing her thigh, through her butt.
Something suddendly happens as you go through some flesh. Is it some kind of filter, or is it her kidney. YES it is.
You became now yellow. You are part of her piss...
...
...
You are being washed through a long pipe and to her bladder ...
It is still very empty in here. You think how short was your journey and how "likely" it is that you are found again by your sister on anybody...
Yet, you enjoy the thought of being down here at the bottom of your sister body and belly, close in between her legs. You were always thinking that she was lucky getting this beautiful body. The weird situation you are in is forgotten but your satisfaction and desire to be here in the bottom of this attractive woman body. She walks, she sits. She opens her legs or cross it. No matter what she does, you are just here, and you can't help enjoying it.
...
Every some time a new stream of piss goes inside and turns you around, filling the place little by little.
You understand your journess is close to its end. Soon you will pass through her piss hole and down to somewhere else... You want to stay here but you also want to experience this last moment.
The bladder is now real full, and you assume that she is about to make her busyness soon. In your ability to "see" you understand that she sits down and your last trip is about to happen
