Mary yawned as she went towards her bedroom, after that long session with the she-wolves, she felt extremely tired, to the point where she decided to become human again.
While making her way to the bedroom she heard her sister groan, she checked her and saw that she was on the ground, she quickly went towards her.
"Rose! What's wrong?!" She asked in panic, "The first... part!" She grunted as she looked at the moon, its effects started as her frontal hooves twisted, regiving her fingers back, although her nails had the same texture and felt exactly like them.
Her back painfully cracked as her chest shifted, giving her a long, slender form with a pair of breasts.
After a few minutes, Rose's metamorphosis was complete, she was now a bipedal wereunicorn.
