Tentacles

The tentacles just appeared out of nowhere, they spread quickly around the school building, grabbing all the students and teachers. Once the tentacles have gotten all their victims, they start exploring the bodies of their victims, using it how they want. They make other people watch and they never stop using the bodies. When the victim is resisting, they force themselves down the victim’s throat to inject a special serum into the belly of the victim to make them obedient. If a victim is becoming aggressive or annoyed or is resisting further they will inject more to enlarge the patients belly to make the victim overweight and embarrassed, the more serum injected, the bigger and more obedient the victim will be. If a victim does not resist then they have more fun.
