A group of step-brothers shrink themselves microscopic and sneak into their step-sister's room while she chills naked listening to music. Completely unaware that they're there, she finds herself getting inexplicably horny as their miniscule bodies traverse her curves, searching for a way in. One makes it to her asshole and finds himself pushed inside by her giant finger. She starts playing with her pussy as another two find their way to her wet sticky pussy lips. Another climbs up to her mouth, getting himself soaked in her saliva as she licks and bites her lips as the horniness intensifies, before being rubbed across her nipple. She has no idea what's gotten her so horny, but she doesnt stop until she's cum and each of her microscopic stepbrothers are inserted deep into all of her holes
