Ravaged by the Unicorn and Bred by the Abhorrent Creature She Birthed Afterward Re...

Tera finds herself chased by a Unicorn bent on ravaging her and using her body to breed. Being both intelligent and able to converse through her mind, the Unicorn not only ravages Tera but also uses her to breed with the very abhorrent thing she gives birth to.
Disgusted by the creature that escapes her womb, Tera can only watch as he breeds her and uses her to give birth to another mutant monster.
After being told that she will breed until both a male and female are birthed, will Tera be able to cope with what is happening to her body? Entirely violated and terrified, can her body even go through with the multiple births and ravages within a single night?
