Shrinking problem

You wake up one day on something soft and massive. you see a ginormous bed in the distance. Your sisters bed? She wakes up completely naked! You try to look away but she grabs what you are on. "Alright time to get changed!" You finnaly see her milky white thigh goes through one hole than the other. Your screamed as you are lifted towards your sisters vagina. "This is so weird." You say. Your 16 and your sister is 13. She was always tall for a girl you were 5"8 and she was 5"7. She had pretty large boobs for her age and was built like a hour glass. She had some bad acne though but she kept it under control. Anyways you were thinking all of this to not notice your sisters massive vagina. She walked down the stairs and every step she took made you move up and down over and over again. You slammed into her cilt a couple times. She couldn't feel anything though cause your so small she wouldn't even see or feel you anywhere. One step and plop your in her vagina. Your hormones are on fire but still you are grossed out. "This Is incest so why is my dick so hard!?" Then you start to walk out but you think wow this is a really far walk. You finnaly see the hole and leave but than there is still wet ground and it hits you. You entered her womb. You attempted to climb out but it's to slippery she lays down and it allows me to exit and I land back in her panties and I finnaly crawl out to her stomach. You climb all the way up to her boob towards her ear and you end up near her nipple. "I can take a short detour right?" You always had a boob fetish. You go to her nipple and you just look. Than she moves and you fall in! You wake up and you see some white liquid and you notice it's her milk you drink it and it's okay. You crawl out and she's asleep. She always snores when she's sleeping. You crawl up her face and doge her mouth but than a massive gust pulls you in her nose. You land in mucus and scream as you sink down. You try to escape but end up swallowing mucus from your 13 year old sister. Stuck in her mucus you are able to slightly get out but you end up in a booger. You try to move but you end up deeper. All this movement irritated her nose cause you see her finger. She sticks it up her nose and the booger gets stuck to it. She than says "this little booger was making my nose itchy?" I notice that to her this booger is so small it's barely visible and she just sticks in on her desk. I'm able to move out and I fall off the desk onto something sticky. I just give up and sleep. "Where's my deodorant? Oh here it is!" You wake up and see her hairy armpit as your rubbed against it and you end up getting stuck to it. You swallow alot of disgusting sweat but you escape eventually falling down
