Getting ready for bed in my red plaid onesie and black socks. I take my usual sip of water before climbing into my comfy bed. After dozing off for a while I am awakened by a strange feeling so I  get out of bed to try and figure it out. Feeling warm and tingly my whole body starts feeling like it's growing. Before I know it my boobs have grown double their size and then my butt, arms and finally my feet have grown out of control and Ive become a giantess.
