Melissa adjusted her mask. She was dressed as Catwoman - a sexy costume she had created to attend an unexpected Halloween party. A one-piece bodysuit, worn over fishnet stockings, with long gloves and knee-high leather boots - all black. The mask and cat-ears added the finishing touches.
Jack had agreed to play along; he was dressed as Batman. Not having as much wardrobe to work with, he had purchased the costume from a local shop. It was a bit much, but he was having fun with the utility belt. He'd already added some of his own "tools" into the belt's various pouches.
The drive to the party wasn't long. Jack parked across the street. "Before we go in, I have another item for your costume that I want you to wear."
"Oh, what's is it?"
Jack pulled out a furry black cat-tail and wiggled it.
"Oh, perfect," she said. "How does it attach?"
"That's the best part," he answered, showing her the small, ovoid end. "Your suit opens at the bottom; I think it will fit between the snaps. This plug goes in your ass. No one will be able to tell."
Melissa wasn't sure what to say. She'd never tried a butt-plug before. The thought scared her a bit, especially in public. But she also found the idea kind of exciting.
"You did say you'd try anything once," Jack reminded her. "And it really completes the costume," he added.
Maybe it was the rum and coke she drank earlier, or maybe it was the lust in Jack's eyes. Or maybe it was the warm tingling feeling between her legs. Probably all three she decided. "I'll try it," she consented.
He smiled. "I thought you would. Turn around and spread your cheeks for me. I have some lube, but we should relax your hole a bit first.". Melissa looked around nervously. She could see other party guests arriving.
She lowered the car seat as far as it would go and lay down on her stomach. Jack felt between her legs and unsnapped the suit. Melissa reached back and spread her cheeks apart. His fingers began to caress her slowly, sliding between her lips.
Still nervous, she was surprised when she realized how wet she was. His finger slid easily into her pussy, and the smell of sex began to fill the car
She could feel her heart beating faster as Jack continued to finger-fuck her. And then he leaned over, and she felt his warm tongue licking her, exploring, tasting, probing into her asshole. He paused only for a moment, whispering how much he loved her scent and taste.
Then she felt his finger pushing gradually into her tight hole. She moaned as it slid in deeper, still slippery from her pussy cream. She lost track of time, but she could feel her hole relaxing, opening, welcoming him in.
