Henry immediately got hard at the sight of Joanna standing in his living room wearing nothing but a tiger striped fur coat. The extra breasts were strange but sexy. He kissed Joanna and his hands went to her extra breasts which seemed surprisingly real. He caressed the others for comparison and found they felt the same. The couple made their way toward the bedroom - kissing, fondling, bumping into things, and shedding Henry's clothes along the way. But the coat stayed on.
They finally reached the bed and Joanna lay on her back. Henry began to play with her nipples with his tongue and mouth while Joanna fondled whichever pair he wasn't currently giving attention to. Joanna grew wet and finally pushed Henry off then bent over the edge of the bed, her ass in the air.
"While you're wearing the coat?" asked Henry.
"Yes!" answered Joanna without hesitation.
Henry didn't understand Joanna's obsession with the fur coat, but he was too horny to argue. "It makes you look like a tiger" he said before plunging into her. Each thrust from Henry drew a low moan of pleasure from Joanna. He really enjoyed being taken by her mate this way. They could call it tiger style. She also loved the feel of Henry's hands on her fur. Yes, her fur, she thought. She loved the coat - it was practically a part of her.
Joanna's thoughts were interrupted by further changes.
"You're growing a tail!" announced Henry.
"What kind of tiger would I be without one?" she said. The words were out of her mouth before she realized she said them.
Henry realized Joanna was somehow turning into some kind of catgirl. But like most guys he thought catgirls were sexy. As he continued to thrust, he scratched the base of Joanna's new tail and that was enough to send her into an orgasm, which in turn caused him to climax.
The lovers collapsed on the bed and Henry could definitely hear Joanna purring.
