Matt, and he's already tried her patience

Sarah was used to being the center of attention, the striking figure that all the guys (and some of the girls) couldn't keep their eyes off. Usually, she greatly enjoyed stealing the show, but not so much when more than half her audience were weird nerds. When she caught Matt staring at her tits again as she looked up, probably under the pretense of looking at her new necklace on her neck, Sarah felt the last of her temper wear away.

Screw playing it safe, screw easing the nerds into embarrassing themselves, she needed some payback, and she needed it right now.

In one snatching motion, she grabbed a slip from the hat and ripped it out to read. Fortunately for her, it bore the name of exactly who she wanted, and she had the perfect little ploy to punish the person that name belonged to.

"Matt," she smiled, "thanks soo much for the necklace. I'm sorry I don't have a gift to give you in return, but I think there's something I can do to at least partway pay you back."

Matt's eyes had widened behind his glasses and his goofy smile had grown as she had spoke, as if he was foolish enough to genuinely believe everything she was saying. Her **** smile became a real smirk just at the thought that he could be so naïve.

"I dare you to join me in the hot tub!"

Matt's smile faltered a little at the suggestion. "Oh, I d-d-didn't bring my s-swimming trunks," he stammered, but Sarah had known he was about to say that. Grinning like a Cheshire cat, she loosed her simple reply.

"We can just go skinny dipping, duh," she said, tilting her head as she spoke as if it were obvious.

Matt's reaction to that was exactly what she had expected. Wide eyed fear, followed by a moment of wordless contemplation. While Tom cheered at the suggestion and Miranda whistled jokingly, Sarah could see gears turn in Matt's nerdy head.

Obviously, the thought of Sarah's perfect body completely nude, save for some sudsy bubbles, was enticing to him, but the prospect of being naked himself threatened to outweigh that potential upside. For a little while Matt's mind silently went back and forth, images of Sarah's big breasts on full display without even a scrap of tape to hide her cute nipples, fighting valiantly against his self conscious concerns.

When, after a few seconds of staring, she tired of looking his anxious face deep in thought, Sarah decided to throw him a line.

"Well. . . " she began, dragging the syllable out as if she were thinking as she spoke, "if you really don't want to go skinny dipping, I guess I might have one of my brothers old speedos lying around from before he moved out. Would you prefer to wear one of those?"
Sarah had barely finished the question before Matt leapt at the opportunity.

"Uh huh, yeah, I'll w-wear that," he said, nodding rapidly like a bobble head.

"Perfect," Sarah smiled again, "come with me and we can both get changed into our swimsuits." She stood as she spoke, full breasts bouncing slightly as she got to her feet and momentarily distracting Matt. Blinking quickly and looking away, he stood up too, only to raise a skinny finger before she could lead him to her bedroom.

"B-both get changed? I-I thought you wanted to go skinny dipping?" He asked. Everyone else in the room immediately laughed at his brazenness, with Sarah herself even raising an eyebrow in surprise. It seemed that he did have a pair of balls after all.

Allowing herself a rare, genuine smile at something he had said, Sarah turned to face him in the doorway. "Don't push your luck," she warned in a low voice, before turning her back on him again and heading out the door. Matt scurried to follow, ears flushing red as the others laughed again. The sound was muffled once he threw the door closed behind him, before quickly facing forward to see where his crush had gone. When he saw she was already halfway up the stairs, he raced to follow, sticking close to her elegant heels like a lovesick puppy.

Swaggering up the steps in front of him, Sarah reflected on just how perfectly her plan was going.

She might not have been very book smart, but she knew an awful lot about getting her own way. If pouting, batting her eye lashes, and using her princess voice didn't work, then she would always fall back on her actual skills of negotiation. One classic strategy was to make an outrageous first bid that you knew the other person would not accept, so that your real bid would appear more reasonable.

That was what she had done to Matt, making it seem like she had "compromised" on him wearing a borrowed swimsuit when that was what she had actually wanted all along.

Because it wasn't just a speedo, and it certainly wasn't her brothers. It was really just one of the oldest tricks in the book, something she had held on to since she was just a little prankster, instead of the adult social butterfly she was now.

"The Magic Dissolving Speedo." It had come as part of a prankster starter kit, alongside a whoopie cushion, electric hand-buzzer, and other practical jokes. It looked like a regular speedo, until it get wet, when it became completely and near instantly transparent.

It was the perfect tool to humiliate a nerd like him. All she would have to do would be get in the hot tub with him, and then wait. Whenever he stood up for another dare, or to get a drink, or just to go for a piss, his little shame would be on full display in front of absolutely everyone. And the best part? She could simply play dumb. She would say she had no idea that would happen, she'd wonder with the others why her brother had ever owned a speedo like that, and she'd suggest that maybe that design flaw was why he hadn't taken it with him when he'd moved out.

Already smiling to herself at the prospect of her plan unfolding, Sarah rubbed her hands together villainously, before popping open her bedroom door.

Turning to face Matt, she caught him finally cresting the stairs behind her, a winded look on his bespectacled face. She didn't think she had gone that fast, but maybe her excitement had made her walk quicker than she thought, or maybe he was just even more out of shape than she realized. Whatever the cause for it, Matt's deep breathing caught in his throat as Sarah cocked her head and smiled at him. With one manicured hand, she gestured towards her room, that faded quickly into blackness beyond the light of the hallway.

Matt looked trepidatious now, as if the darkness and Sarah's playful tone had put him suddenly on edge in fear of an unpleasant surprise, but he still dutifully obeyed. In small steps he shuffled forward, eyes straining behind his glasses as he crept into her bedroom. Sarah was soon on his heels, pulling the door tight shut behind them both. The last thing she saw before the light was blocked out, was Matt nearly jumping out of his skin.

The first thing she saw once she flicked the light on was his nervous face, turned to look at her with big, shocked eyes. Chortling at his reaction to just a bit of darkness, Sarah glanced past him to her room beyond.

Everything still seemed to be where she had left it. Fluffy white pillows were piled up at the head of her spacious doubled bed, the door to her walk-in closet was still closed, as were all the drawers of her dressers and bedside tables, and everything on her sleek vanity unit still seemed to be where it should have been. Sarah always liked to do an inventory of her stuff after a house party, to make sure no one had touched any of it, and to make a reminder to punish anyone who did.

Satisfied that her bedroom had gone untouched, she decided to carry on with her plan. Breezing past Matt, she crossed the plushily carpeted room to the chest of drawers opposite the foot of her bed. Throwing open the bottom one, she reached deep into it, pushing past cozy pajamas and other casualwear in search of what she knew still rested at the bottom. Near the back left corner, she found it, a manicured finger brushing against the hard plastic box that she knew contained what she was looking for.

After only a little more rummaging, she drew it out, holding the box low to the drawer to make sure Matt wouldn't see it. She could see the speedo through it's Perspex confines, just below the somewhat worn heading of "Magic Dissolving Speedo." As covertly as she could, she tore that telltale box open and hid it back inside the drawer, whilst holding the thin piece of swimwear in her other hand. It was smaller than she had remembered, a tiny scrap of pale blue and white fabric, but she imagined that it was probably still plenty big enough for Matt.

"Here you are," she said as she turned around and straightened up. She tried to ignore that Matt had almost certainly been staring at her ass while she had bent over in her drawer, as she handed him his new piece of swimwear. Gingerly, he took it from her, holding it up on one finger to inspect it in the light. The look on his face was anything but pleased. If he already thought it was skimpy, then he would be in for a real shock once it touched the water.

While he distracted himself frowning over his borrowed speedo, Sarah set to work on finding something for herself to wear. There were plenty of options for that in her closet. One pieces, two pieces, bikinis, tankinis, retro bikinis, high waisted bikinis, thigh cut bikinis, monokinis, she had them all, and she knew she looked incredible in all of them.

Ultimately, she decided on a blue and white strapless bikini, to match what her new "partner" was going to be wearing. When she reemerged from her deep closet, she saw that Matt was still fidgeting with the speedo, stretching it out between the index fingers of both hands.

"Why was your b-brothers swimsuit in your room?" He asked, inadvertently putting a foot into the one plot hole of Sarah's plan. it didn't take long to come up with a lie, however.

"It couldn't stay in his room, my dad remodeled it to be his office. I was just holding on to it for safe keeping," she explained, masterfully weaving truth and lies together. "I'm sure he won't mind you borrowing it for an evening, and I'll throw it in the wash before he comes back around again."
"But enough about the speedo," she continued, a wicked grin appearing on her face, "it's time for you to wear it."

Matt gulped, the elasticated speedo snapping off of one finger to land against his other hand. "O-okay, I'll just go the the b-bathroom and-" he began to explain, only for Sarah to cut him off again.

"Nah, just get changed here, it'll be fine," she said, "I promise I won't peek. And you better not either." Her voice and her brows lowered for that last sentence, pinning Matt with a look that declared that she wasn't joking. Gulping once more, Matt turned his back on her and began to strip, slowly unbuttoning his sensible white shirt.

Smirking to herself, Sarah returned the favor, facing towards the opposite wall as she began to take her own clothes off. She had already made a good start on that downstairs, by taking off her skimpy top, such that now all she had to do to finish off her upper half was peel off her nipple tape. Gingerly, she pulled that sticky backed tape away, hissing through her teeth as it clung briefly to her sensitive nipples. They rapidly hardened in the night air, the peeling of the tape having caused some of her blood to rush to them.

Her new necklace quickly slipped over her head too, and she put it down on her bedside table for later.

Once that was done, her tiny skirt and panties fell away much more quickly, leaving her naked body in all it's glory. Without turning around, she reached behind herself for her bikini that she had laid down on the bed. Despite intending to embarrass Matt later anyway, she didn't want to get caught peeping right now. The last thing she wanted was for him to tell anyone that she had tried to sneak a peek at his pecker.

Once her groping hand found both pieces, she brought them up and quickly slid into them. The strapless top did it's best to restrain her heaving breasts, whilst the form fitting bottoms hugged tight to her fat ass. From her rolling cleavage, to her flat stomach, to the underside of her soft ass cheeks, both articles were still so scandalously flimsy that she showed off a lot of skin anyway, but she doubted anyone would complain. One person who she knew would not complain, was currently standing right behind her.

Deciding that he had had quite enough time to squeeze into his speedo by now, Sarah turned around without even asking if he was ready. Fortunately for him, he was, but even though he was dressed Sarah saw that he still stood resolutely facing the other wall. "Aww, he's waiting for me to tell him it's ok to look," Sarah thought, "so cute."

Looking at the back of his head gave Sarah an idea. As quietly as she could, she crept up on to her bed, kneeling on it and striking a pose like a supermodel. "Okay, you can turn around now!" She cried, placing one hand on her hip and the other on the back of her head. Instantly, Matt obeyed.

A gasp escaped his lips at the sight. Sarah, his crush, was knelt on her bed like a cover girl. red hair spilled down over one shoulder, to her buxom chest, held back by only a blue and white bikini top. From there his bespectacled eyes ran down her flawless stomach to her bikini bottoms, blue and white just like the top, above her lusciously thick thighs.

From the way Matt hunched, blushed, and looked away, Sarah could tell that he had to have been hard already. That was no surprise, when she was looking as hot as she did. What did surprise her, however, was that she could see no trace of a bulge through Matt's thin and revealing speedo. He really had to be packing very little down there.

To be honest, that hollow-looking pouch between his legs was quite in line with the rest of his underwhelming appearance. Narrow shoulders framed a chest without either body hair or muscular definition, with only a few freckles to adorn his pale torso. His arms and legs were nearly hairless too, making him look even less masculine.

Despite all that, Sarah still found her attention drawn intractably back to his crotch, and the spot where his bulge should have been. His dick was conspicuous by it's absence and, even though she really should not have cared what was between that nerd's legs, she still found herself thinking about it.
