Helen took a deep breath as she steadied her beating heart, one threatening to explode in her chest as the commitment her costume for this evening became more and more apparent. She could still back out, she knew. She could stay home, and no one would know or care. But she would know. She would care. She cared enough about this event that she accepted the written invitation. She cared enough to know what she was getting into, even if she also knew that she didn't.

She flexed her hands to relax, and her heart slowed down just a little. Her costume was simple, yet in her mind, utterly provocative. Something that she could accept would get her into a lot of trouble if it was found out.... but she wanted trouble, didn't she?

Her costume was a black one-piece swimsuit, from her crotch to her shoulders. It was tight against her skin, but not too tight. She wanted to be able to breathe well. But she had the front of it open, the slight zipper pulled all the way down to to expose her navel. But that wouldn't be enough to cause her to react like this. Not one bit. She had worn this before with complete confidence.

This wasn't confidence.

She had very carefully drawn a line up her front. It reached down from her slit all the way up. Inspired by some pictures she had seen, she realized she could go all the way with a thing that was used for a sexual joke in the first place.

The line that ran from sex to neck had little horizontal lines marked on it, and words written at each line.

At her pussy was two words written on the side. 'Entry Fee'. The only way people would see that would be if she stripped - or they cut her swimsuit open there. Either would be a definite option. There was no way she was coming out of this evening without either or both happening. The next line was an inch further up, with the words 'Nice Try' in fine penmanship. For those who weren't making an effort. Then, at the limit to her vagina, a third line. 'Cum here' was the command for those who reached that depth.

For those who dared to go further, there was another line at the top of her womb. "Press Through" was the encouragement she wanted to give anyone at that point as the next line was now visible above her navel. "Keep Going!" the words said as anything that got that far into her would be inside her guts. A handspan above that at the bottom of her ribs was another line. "Halfway there!" she ran a finger up her bare skin, tracing the vertical guideline. Between her breasts was "Maximum Jiggle". She smiled at that as she moved up and at the base of her throat, the small line turned into a very long one. "Remove Head?" the question was posed of anyone who got that far into her and part of her wished they would. Wished that they wouldn't.

But the line kept going up, under her chin. "Claim Prize!" it read, the final line. The final note on her real costume.

Tonight, she would find out how many would.

He grinned into the mirror, his teeth on full display as he examined his sharp inhuman canines. "Greg!" his wife called out to him, and he closed his moth, running his tongue over his teeth carefully. "You good?" she asked as he stepped out of the closet.

He opened his mouth again, and his wife, dressed as a succubus with breasts exposed and what clothes she wore skin tight, looked. "Those look real!" she exclaimed.

"They are!" He assured her.

"Really?" she asked. "This is full of tricks, you never know."

She looked at him expectantly. He delivered on her expectations as he wrapped his arms over her shoulders, pulling her head back and biting into her neck as a vampire would. Under his embrace, she wilted as he drank her blood from her ripped throat, her moans of joy mixed with the gurgling of her breath.

He dropped his wife to the floor, wiping his mouth clear of the worst of her fluids. There was applause and a man and a woman clapped with appreciation for what he had done. "Thank you," he drawled with a practiced Bela Lugosi accent. "I will be here all night."

"And her?" the woman - dressed in a jungle outfit to match the man beside her.

Greg smiled. "A quick refreshment, you know?"

The two observers laughed. "Have fun!" the man called out as they walked away.

"I will!" Greg promised.

Eve wasn't dressed for this. Oh, she absolutely was, but standing there, watching as the Club Head was butchered like a pig for the gratification and enjoyment of everyone before she opened the doors and invited everyone in had caused to realize that perhaps showing up in a shimmering black evening dress may have put a little too much focus on the orgy that was going to commence and not enough on the magic and mayhem.

Sure, her hair was tied too behind her head, and a brass necklace turned into a pendant that slid between her breasts. But that was just an accessory to the fact that her top made it clear that she wasn't wearing a bra with how it showed off the sides - in and out - of her chest, and the slits up the sides of her skirt strongly suggested she wore nothing under there either.

It wasn't a suggestion.

"Imagining yourself up there?" A suave masculine voice spoke up from beside her as they filed into the house that was larger on the inside. Eve glanced at him, a man in a fine suit. He was definitely looking at her.

"Perhaps," she was, but part of her was afraid of committing to that. "You?"

"Nah, not my style," he replied as they crossed the threshold. "What are you dressed up as? Lounge singer?"

"International Woman of Mystery," she replied, having not thought that far ahead. "You?"

He laughed. "International Man of Mystery!" he gave her the same answer back to her own shock and embarrassment. "Sorry, had to."

"Well then, Mister IMM," Eve gathered her courage and offered her arm, "shall we discus business?"

"And what business will that be, Mrs IWM?" He asked as he took her arm and they found themselves walking toward a set of stairs.

"That I will be on top first," she informed him. "After that.... a death trap?"

"For me or for you?"

"Hence the negotiations."

"I'm sure we can come to a mutual agreement then."

Yes, this was looking up already. She was definitely dressed for this!

She wore strings. That was her costume. She walked boldly into the house, ignoring everyone around her for now as she knew her time would come. Her bra was wire. No fabric as her tits were held in by a wire across them and a small plastic jewel over her nipple. Her bottoms were a string with plastic beads hanging from them around her waist, and she had carefully cut the cloth out of the small section that covered her pussy.

She walked up to the first young man that caught her eye as he was dressed like a lifeguard. She smiled as he looked at her. "Who are you?" he asked. "Nice costume," he added as a compliment.

"Hello!" She replied. "And I'm dressed up as your sexy girlfriend," she told him. She pressed herself against him, feeling him rise at the touch and whispered in his ear, "I hope I don't have to cheat on you."

"If you cheat on me," he replied as he pulled her close, "I'll have to punish you. But for now, I saw a pool out back. Shall we?"
