Harley woke up from her nap sleepily rubbing her eyes when she heard a jingle sound like a bell. She sat up and realized she had a tail. For a few seconds she was silent but eventually she screamed loudly.

"Harley what the hell is with all the racket?" The Joker yelled coming up the stairs.

"Don't come in!" Harley yelped and pressed the door shut firmly. She couldn't let him see her like this or he would get mad.

"Harley are you ok?" He said suspiciously. She was acting odd again and when this happened something was always wrong.

"Nothing Puddin I just had a bad dream" she lied.

"Well then why won't you let me in?" he said since usually if she had a nightmare she would run to him for comfort.

"I...I'm not decent" she said nervously which was true she was only wearing her red lingerie nightgown.

"Ok then well I'm gonna take a shower" he lied releasing the handle and pretending to walk off.

Harley waited and then breathed a sigh of relief and released the handle slowly "Phew that was close" she sighed heavily.

The Joker slammed open the door and grabbed her by the wrist "You dumb broad your too easy to fool" he snapped crossly. There was a jingling noise to which Harley's tail appeared from behind her back. The Joker went quiet and then yelled loudly in shock "What the hell? Harley where did you get that?!" he yelled.

"I dunno Mistah-J It was there when I woke up honest!" she said worriedly.

Suddenly a cat appeared from the window with a note in its mouth to which The Joker took and then the cat fled. He opened it and read it to which a frown appeared on his face.

"What does it say Puddin?" Harley asked curiously.

Dear Joker

I am sure you've seen Harley's little transformation by now

Think of it as a gift from me

Enjoy your little role play theme

Catwoman

The Joker frowned "It seems Catwoman drugged you the other night with that dart she shot at you" he said crossly.

"Crap I can't go out like this people will laugh at me!" Harley sniffed.

The Joker patted her head "No need to cry Harls I'll find a cure but until then I'll have to do heists alone" The Joker said gently.

"Thanks Puddin" Harley cried hugging him lovingly. Suddenly she began purring and her tail waved about.

"Um Harls your purring" The Joker said feeling awkward.

Harley jolted and backed away "Sorry Puddin it just felt comfortable and cat's purr when their happy" she said apologetically.

"I see well continue" he said to which she happily obeyed. He peered at her and smirked "Now that she's stuck like this she does look kinda SEXY" The Joker thought to himself.

Harley cuddled up to him and began waving her tail about happily. It was black and so were her ears; on her tail was a small red and black bow with a cat bell in the middle.

The Joker hesitated and then began stroking her hair making her purr louder. He sighed heavily "Ok Harls the purring is ok now but you had better NOT do this during sex or in your sleep" he said firmly.

"Um Puddin Red told me that cats are nocturnal...sort of" she said nervously.

"What does that mean?" The Joker said raising an eyebrow.

"It means I sleep during the day and be awake mostly during the night" she said smiling sweetly.

The Joker smirked and pulled her onto his lap "Well I better make the most of this before dawn comes" he said and began groping Harley's chest.

Harley blushed "Puddin...I...wait...nngh" she moaned pleasantly as he massaged her breasts with his hands and pinched her nipples.

"Don't be a party pooper Harls let daddy have his fun" The Joker said firmly.

"Y...Yes sir just...ah...Mmm...don't be too...oh...rough" she moaned as he rubbed her panties.

"I can't make any promises pooh" he teased and began licking her neck. This was going to be a night to remember he had read up that cat's were more sensitive than humans in smell, taste and touch not to mention sound.

Harley saw him smirking and blinked innocently "Mistah-J?" she said curiously.

"It's nothing Harls I'm just very happy right now" he said and pulled her into an intense kiss.
