SPIKED TEA - BE

My evil sister is visiting me! She is all curvy and has big boobs, while I am flat as Hungary. We haven't spoken in a few years, and all of a sudden she is visiting. I bring her tea and all of a sudden my bookshelf starts acting out and books keep on falling off of it. She takes advantage and spikes my tea with something. Somehow I feel an itch and I am restless and it feels like something is wobbling inside my chest and OMG! My skin! I can feel my skin stretching. What has she done?
