Corrupted by Tentacles

Jenny is a summoner of demons or she would be if she were any good at it. Humiliated in her conjuring class, she decides to bind a demon from a dangerous dimension and bring it to her class. Unfortunately for her, the plan goes terribly wrong and instead of summoning a simple, harmless monster, she succeeds in pulling a disgusting tentacle beast through into our dimension.

When the creature easily escapes her simple spells, there’s nothing Jenny can do to stop it from violating her then corrupting her mind with its vile intentions. As its evil starts to twist Jenny’s personality, she finds her body changing and growing a new and very pleasurable appendage. Falling into depravity, can Jenny prevent the corruption from turning her into the monster she fears? Can she stop herself from ravaging her innocent flatmate?
