a wolf

You had decided to combine her with a wolf. You had the woman strapped naked onto a table. She was a little difficult at first, but after you cast a dizzy spell on her, she was much easier to handle. The ritual could begin.

You collected some wolf hairs and placed them on the woman's stomach. You placed your hand over her and summoned your magic. This put an ethereal glow over your subject. The woman started to become worried and asked "What are you doing?"

You chose to ignore her and continue the spell.

"Stop it." She said softly.

You continued to ignore her and persisted the spell.

The woman began breathing heavily. She felt something was happening to her.

"Stop it! Stop it, please! Somebody, help me!" She tried to say. She was too dizzy to resist at all and was completely at your mercy.

Finally the preparations were complete. The merging could begin.

The woman's stomach became like liquid, allowing the hairs to disappear into it. While they were absorbed by the woman's body, she started to change.

Her ears moved up her head and became pointy. Next she grew a thick, medium sized tail, and hair covered both her tail and ears.

At some moment she opened her mouth and you saw some of her teeth, her canines, grow in size.

The last thing to change were her nails, which turned into claws.

Once that was done, the merging was complete. You ended the spell and retracted your hand.

You had turned the woman into a wolf-girl.
