a bee

You had decided to combine her with a honey bee. 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. You had expected many transformations to happen on her backside, so you had her lie face down. The ritual could now begin.

You collected the remains of a bee and placed it on the woman's back. You placed your hand over it 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 back became like liquid, allowing the honey bee to disappear into it. While it was absorbed by the woman's body, she started to change.

At first, she started to grow a tail. This was odd to you, because bees don't have tails. But eventually, this tail grew in thickness until it resembled the abdomen or a regular bee. Including the black and yellow stripes.

Next thing to happen were four transparent wings sprouting from her back. Two on each side.

Finally, a pair of black antennas sprung up on top of her head. Their base hidden by her hair.

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

You had turned the woman into a bee-girl.
