You realise that you have become your sisters pink panties and you see your sister pull her plain white panties and put you on. You try to get away but your limbs were ineffective, and you tried screaming but you heard no words come out, your sister just laughed and pulled you right up to her vagina. You noticed that your nose was right in her backside and your mouth was at her vagina she then laughed again and let out a loud fart right into your nose and it smelt bad. You noticed that your sesnses were working even better than normal as you found out from your sisters farts. She then lets out one big wet fart which caused skid marks on her panties, on you. Why was she doing this you didn't take anything from her. Then you felt a drip onto your face it was a drop of blood coming from her vagina, she was going to have her period without a pad or tampon and cover you in blood just then you are hit with a gush of blood which covered you. You are kept as your sisters panties for a long time as she keeps bleeding onto you and laughing, you think she even peed a bit onto you as well. After a while you are removed from under your sister and she says "poor little panties all covered in blood you'll need a good cleaning" and with that she throws you into the now full washing machine and starts it.

In the washing machine you are thrown about every was and your eyes were stinging from the detergents and you felt sick.

After about an hour the washing machine stops and everything is taken out including you by your mother and put on the clothes line to drip dry. Then your Suzie later notices you and says you still have some blood on you and throws you back into the washing machine for another round.
