Final Destination For Tiny Step-Bro

You're supposed to be taking your Step-Sis to the gym but instead you've found yourself shrunk! She is completely unaware and thinks you've messed her around and left the house. You attempt to climb her in order to get her attention but instead get stuck in her sock!
She decides she needs a tan and borrows your car and drives to the tanning salon, the whole time you are stuck to her sock and can't get off. The car engine rattling your tiny body.
She puts her socks and you on the sunbed to keep them nice and warm... oh no this is not good. You have a birds eye view of her getting undressed, it's so weird and wrong to see your Step-Sis like this but she can't hear you crying for help.
At first the warmth is nice, your little body needs the extra heat. But then all of a sudden you start to sizzle, this thing is too powerful for a tiny little thing like you. Again you climb her giant body resting on her nipple to try and get her attention, but she almost scratches you off so you work your way back down her body in fear. You need a hiding place from these rays... a hole of some sort... Aha! Gosh this is strange being on your Step-Sisters pussy, you might as well give it a little lick while your down there she probably won't even feel your tiny tongue. But she does, she is so confused as to why she's getting these sensations downstairs but might as well make the most of it. Oh no, she starts to finger herself pulverizing your tiny body. You can hardly breathe! The more you scream the more it vibrates and she really gets into it, putting a finger in for good measure. Your whole body now inside your Step-Sister with absolutely no where to escape.
