Wasp, just back from fighting the symbiote, about to go to sleep.
Her powers to change size could be useful to hide me until I have more minions, the symbiote thought to itself as it hid, waiting for her to fall asleep.
When she was sound asleep it slid up her bed and under the covers, it moved in between her legs, firstly it spread to her vagina, so that if she awoke, she wouldn't resist, it spread up her slender body and down her legs, making her toes clawed. It slid around her boobs, dissolving what little clothes she was wearing, her boobs began to expand to D's, wasp groaned and rolled over, the symbiote stopped, hoping it could complete the transformation without waking her, once she went still again the symbiote spread along her arms and up her neck, her fingers becan long claws as it also covered the back of her head and finally, once the rest of her body was covered, it covered her face.
Wasp awoke, startled.
