Before today you lived a mostly normal life. You're an eighteen year old girl, living in a major American city, finishing up her last year of high school. Before today everything in your life was mostly normal.
You wake up to the sound of your alarm, but as you get up you notice something coming out of your back. Two long meaty limbs, coming from your upper back down to your feet. You're horrified by the sight of them. They look like some cthulhu would have given you.
Half asleep you shut off your alarm and start examining them. It feels weird to have these huge tubes coming out of yourself. You try and lift one like you would your arm and it lifts up easily. It's like any other limb.
Not yet awake enough to realize how weird this is you look up on your phone "I have tentacles". What you see is even stranger, people talking about these strange limbs like they're just a normal part of the body. All the images of people you see have tentacles too, this is so strange.
