Chapter 1

"I dare you to eat a bug."

That's how it got started for Stacy and Tracy. The twin girls were just five at the time and ever since they had been daring each other to do wilder and crazier things. At sixteen they had discovered boys and boys had discovered them. Long blonde hair, slim with those coltish good looks that teenage girls seem to attain so easily and older women try the rest of their lives to get back. Their dares too had taken on a distinctly sexual nature. And that, dear reader, is where we come in.

"I'm bored." Stacy did her best pout for her sister. It was a pout she was famous for and it always helped her get her way with her parents. Tracy was not moved at all. She knew her sister too well.

"So go read a book or something." Which is exactly what Tracy was doing. She showed the book to Stacy, hoping it would get her to go do something else.

Stacy made a big show of squinting while she read the title.

"'Schrodinger's Cat.' What's it about?"

"Quantum physics."

"Oh goody. Dibs on reading it after you." She literally dripped sarcasm.

"Fine. I will keep it all too myself then." The book's title was indeed from a Quantum Physics theory about a cat in a box. The story however was pure porn. Tracy liked to outsmart her sister like this. It helped to make up for all the times Stacy had manipulated their parents. Tracy was never any good at that. She went back to her story while her sister paced about their lounge room.

"Dammit, I'm bored. I need something to do." She pulled down Tracy's book and looked her straight in the eye. "Give me a dare," she teased.

"Some other time. I really want to finish this book." Some woman was frigging herself with a banana while her brother in law watched. It was really getting interesting.

"Come on. I'm really, really bored. It's a proven medical fact that people can die from boredom. You don't want me to die do you?"

"Well at least I will finally get some peace and quiet."

"Pleeeeease!"

At that moment Tracy spied someone walking by the house. It was Clifford, the school nerd. Her eyes lit up as she saw her opportunity to embarrass her sister.

"Okay, I have a dare for you."

Stacy saw the look in her sister's eyes and knew straight away this was not going to be pretty. She thought briefly about trying to back out, but knew that would make her a slave for life to Tracy.

"What is it?"

"I dare you to go outside, get Clifford who is walking by right now, and bring him in here."

"Is that it?" Stacy was overjoyed at how easy this dare was. Her joy was to be short lived though.

"No, that's not all. When you get him in here you have to make him cum." Tracy was trying hard not to laugh out loud. Stacy was going to be so embarrassed about this.

Stacy's jaw dropped.

"No way. I am not going to get that geek to cum. Not a chance."

"Okay slave for life. I need a foot massage." Tracy kicked her shoes off and waggled her toes at her sister.

"Oh god no, anything but that. All right I'll do it. But what about Mom and Dad?"

"They won't be home for hours. You know what mom is like when she goes shopping for clothes."

"Yeah I guess, are you going to sit there and watch?"

"Oh I'll be watching all right, but I'll do it from in there." She pointed to a cupboard with a louvred door. It was almost impossible to see in but very easy to see out. Tracy dropped a wink at Stacy as she got up and walked towards the cupboard.

"I don't know how, but you are going to pay for this, sis." Stacy opened the front door and took off after Clifford.

Tracy opened the cupboard and stepped inside. Closing the door behind her she pulled up an old stool from the back of the cupboard and sat down. She adjusted the louvres just as she heard Stacy and Clifford come in through the front door.

"I still don't understand why you wanted me to come in here, Stacy. Why won't you tell me what you want?" Tracy knew that Clifford's whiney voice must have been driving Stacy nuts. She chuckled quietly to herself.

"I just needed to tell you how hot you are." Stacy gave a sidewards glance at the cupboard. Visions of sharp pointy objects danced merrily through her head.

"Really? Me?"

"Oh dear God, his voice gets even squeakier when he's nervous," thought Stacy. She could feel a headache coming on. But a dare was a dare so she carried on regardless.

"Do you think I'm hot, Cliffy?"

"Oh yes, very hot." Clifford was blushing under his coke-bottle glasses.

"Thank you, Cliffy. That is so nice of you to say so." She batted her eyelashes at him. "But do you know what really gets me hot? What really turns me on?"

"No."

"I just love it when guys wank for me. It makes me sooo horny."

"Really?" Clifford swallowed hard. Was this girl actually coming on to him?

"Oh yes, Cliffy." She ran her fingers lightly over his chest. "I just love it when I see a man stroking himself in front of me. It makes me want to throw him to the floor and fuck him. Do you want me to do that to you, Cliffy?"

"Umm... Ok." He was starting to sweat now. He had never been in this sort of situation before.

Stacy leaned close to Clifford and whispered into his ear.

"Wank for me, Cliffy."

"I don't know if I can. I need... inspiration."

Stacy felt like screaming at him. What did she have to do to get him to wank for Christ's sake? She tried her best to remain calm.

"Would you like me to talk dirty to you? Would that help?"

"Yeah it would help a bit."

"Okay, Cliffy, anything for you." She nearly choked on her words. Tracy was going to pay dearly for this. She swore she could hear sniggering coming from the cupboard.

"First lets get you out of those clothes." She unbuttoned his shirt and slid it off his shoulders. Stacy was surprised to see that he had a reasonably good body under that plaid shirt. The nerd must work out.

"I want to feel your body against mine, Cliffy. I want to feel your naked flesh on mine. Is this working for you, Cliffy?" she asked in her sexiest voice as she undid his belt.

"Oh yes" he sighed. He couldn't believe this beautiful young woman was doing this to him.

Stacy undid his fly and let his pants slide to the floor. She marvelled at the world's worst boxers underneath. Stacy wondered how old they where.

"Is this getting you hard, Cliffy? Are you ready to do it for me?"

"Oh god nearly. Could you touch it?"

She was going to puke. Swear to god she was going to puke. There was no way she was touching it. She would rather be a slave than this.

Or perhaps not.

Maybe if she just breathed on it a little it would do the job. After all he was the class nerd. He had to be a virgin. By all rights he should be creaming his pants right now. She knelt before him and grabbed the side of his boxers. With one quick movement she pulled them down to his ankles.

She noticed two important things.

First, he was already hard. Second, he was huge. Absolutely huge. My god he had to be nine inches long and at least four inches across.

"I think I can do it now, Stacy. Wank I mean."

"No that's ok, I'll do it for you." She reached forward and took him in her hands. She had never seen one this big before. She wondered what it would feel like taking one this big as she wrapped her fingers around it.

"Do you want me to suck it, Cliffy?"

"Oh yes please." He looked down at her as she licked around the head, making it moist.

"Mm tastes nice." Stacy wrapped her lips around his cock and slowly slid it into her mouth. She moved her head down slowly till the tip of his cock pressed against the back of her throat. It was hardly halfway in. She moved her position slightly so Tracy could see what was going on. Stacy knew her sister loved a big cock and she hoped she was turning green with envy.

She started to suck a bit harder as she moved her head up his shaft, then pushed down further than before. She was determined to get it all in. She took a breath and then eased it down her throat. Further and further it slid in until at last her nose pressed into his pubic hair. She pulled back all the way to the top and started to bob her head up and down his shaft in quick, bird-like movements.

"Oh god I'm going to cum," groaned Clifford, his neck muscles standing out as he strained to keep control.
