For his twenty-first birthday, Lincoln's sisters Lynn and Lucy took him to Las Vegas.

It was supposed to be a surprise but Leni spilled the beans when she accidentally texted him instead of Lynn one day. Lincoln pretended not to notice and Leni never said anything about it, so she either forgot or was pretending herself. Three days before the big day, Lynn and Lucy came to him in his bedroom and told him the big news. "Are you sure you can afford this?" Lincoln asked.

"Of course I can," Lynn said.

Twenty-three and barely taller than she was at thirteen, Lynn had recently graduated college and gotten a job as a gym teacher at Royal Woods Elementary. Lincoln didn't know her salary off the top of his head, but he was pretty sure that it wasn't grand enough to subsdidize a luxurious Vegas getaway. She wouldn't hear any protest so whether or not she could afford it, he accepted it.

Lucy and Lynn weren't the only ones involved in the planning (and presumably financial backing) of his birthday blowout. All of his friends knew and had contributed, and most of them were coming along. Clyde was taking an accelerated course in psychology so he couldn't make it, but Stella, Sid, and Ronnie Anne were onboard. "We're gonna have a blast, lame-o," Ronnie Anne told his via text the day before they set out.

Despite his misgivings, he was pretty excited. Las Vegas wasn't exactly a place he dreamed of going but he definitely wanted to see it at least once in his life. As far as he knew, there was nothing specific there that he was hot on doing - gambling was okay, floor shows meh, musicals lame - but he imagined a 24/7 party atmosphere and come on, that's cool.

On July 9, two days before his actual birthday, Lincoln, Lynn, Lucy, Stella, Sid, and Ronnie Anne boarded a direct flight to Las Vegas. Lincoln sat in a middle seat between Stella and Ronnie Anne. Stella read from a Las Vegas guidebook, prattling about all the "awesome and amazing" things they could do, and Ronnie Anne watched a movie on the screen attached to the headrest in front of her. "The big 2-1," Ronnie Anne said. "Wait until your actual birthday. We're gonna get bombed."

Ronnie Anne was two months older than Lincoln and had, therefore, able to legally drink for sixty days. She didn't drink to excess or anything, but every weekend she went out and cut loose. She told Lincoln that when he turned 21, they could go out together, but Lincoln didn't know if he wanted to. He had drank before but not very much, so his tolerance was low. A couple cocktails would fade him and what's the fun in puking and passing out before the party even has a chance to start? Ronnie Anne would think he was a loser and could you really blame her if she did?

Six hours after takeoff, the plane descended over Las Vegas. The city rose abruptly from the endless expanse of hardpan like an electric oasis. The terminal was packed with people in light, airy clothing and the street outside was jammed with taxis and private limos. As he and his squad waited for the Uber, he studied the tinted windows of a passing stretch and wondered who was inside. Michael Strayhan? Cardi B? That streamer from YouTube who made fifty million dollars last year playing Pong?

When the Uber arrived, they piled in and took it to the MGM Grand Hotel. Rising over the neon-bathed strip like a modern day Colossus of Rhodes, it dominated the skyline and took Lincoln's breath away. The vaulted lobby was richly carpeted and adjoined by a casino, a buffet, and a showroom. Flashing lights, dinging bells from the slot machines, and the chatter of a thousand tourists overwhelmed Lincoln's senses. "Whoa," Stella marveled, "it's even cooler than I imagined."

"I'm a genius," Lynn said smugly.

Lucy turned to her. "Coming here was technically my idea. "

"No it wasn't."

"Yes," Lucy said, "it was."

The desk clerk came up and forestalled any further argument.

Because Lynn and the others weren't made of money, they rented only two rooms: One for Lincoln, Lynn, and Lucy and the other for Sid, Stella, and Ronnie Anne. Though they were side by side on the same floor, Lincoln's was far nicer. It featured a sitting room, a heart shaped jacuzzi, and a full kitchen. A sliding glass door opened onto a balcony that looked down on the Strip below. There were two beds; one went automatically to Lincoln since it was his birthday and the other became a point of contention between Lynn and Lucy, each one wanting it and neither wanting to share. They finally agreed to each take a side after Lincoln mediated. They were all adults and he was still helping them with their problems. Was he their brother or was he their mother?

The first thing Linc and the girls did was have dinner at an all you can eat super buffet down the street. Lincoln stuffed himself full of clams and crab legs and Lynn pounded BBQ sliders until she could barely sit up. Sid and Ronnie Anne paid the tab and afterward, they went to the casino. Sid and Lucy paired off to play craps while Lynn joined a hike stakes Texas hold 'em game. Lincoln and Ronnie Anne hit the slot machines. "You ever play the slots, lame-o?" Ronnie Anne asked.

"Never," Lincoln said.

She rolled up her sleeves and bumped him out of the way with her hip. "Let me show you how it's done."

Lincoln didn't know much about slots, but he always thought it therefore was a game of chance.

He was right.

Ronnie Anne, however, treated it as a game of skill, bragging on and on about how great she was. She pulled the lever but didn't get three in a row. She tried again and again she failed. "You're really crushing it," he said sardonically.

"Shut up," she grumbled, "I'd like to see you do better."

After her four epic fail, Ronnie Anne stepped aside and Lincoln took her place. He pulled the lever and got three instantly; change jangled into the tray and Lincoln made a face that looked a lot like the one Spongebob gave Squidward when he found out Squidward liked Krabby Patties. Ronnie Anne's lips threatened to twitch into a smile in spite of herself. "Shut up," she said.

"I didn't say anything," Lincoln said.

"No," Ronnie Anne replied, "but you thought it."

Lincoln grinned and shrugged one shoulder. "Yeah, I did."

They laughed, and their gazes met.

A long time ago, Lincoln and Ronnie Anne were best friends. They spent every moment of every day together and shared each other's problems and secrets. In the fifth grade, Ronnie Anne and her family moved to the city. They visited each other and kept in touch but their bond was never as strong as it was when they were eleven. Lincoln could admit now that he liked her then, and if they hadn't been separated, they may have wound up together.

Ah, what could have been.

That was then, however, and this was now. He was too busy with his studies to date and she was too.

In Las Vegas, the casinos stayed open 24/7 and to keep people playing, there were no windows or clocks, so losing track of time was scarily easy. Lincoln and the others were there until nearly 4am. Everyone lost a little bit of money save for Lincoln, whose pockets jingled with loose change. It wasn't much - only ten bucks - but it was ten bucks he wouldn't have had otherwise. Lying in bed and struggling to sleep, he vividly remembered the lights and sounds of the casino and the thrill of playing the slots. He never saw the appeal of gambling before but he did now.

For the next three days, Lincoln enjoyed everything Vegas had to offer: He and Lucy went to cirque du soleil, he and Lynn played poker, he and Sid went rock climbing, he and Stella went on a hike in the desert, and he and Ronnie Anne hit up the arcade for old times' sake. They laughed together, exchanged sly looks, and stood a little too closely. On his birthday, they all wound up at the bar in the MGM Grand's lobby and drank. Lincoln sampled a little bit of everything - Jello shots, rum and Coke, Long Island iced tea, and a dozen other cocktails and mixed drinks. Before long, he felt loose and warm. Ronnie Anne sat next to him and every so often, she'd favor him with a grin and a sidelong glance. He wasn't an expert on girls but with every drink, he became more and more confident that she wanted him.

And he wanted her too.

Lincoln was normally timid, but the alcohol made him brave. He laid his hand on her bare thigh and squeezed. Her skin was soft and warm, the shape of her leg smooth and womanly. Instead of pulling away, she closed her thighs, trapping his hand between them. She stared at him in her periphery and bit her bottom lip, communicating that she was both available and ready.

First, Lincoln excused himself to go to the bathroom, then Ronnie Anne did the same a minute later. They met in the elevator; as soon as the doors slid closed, they attacked one another with drunken abandon. Their tongues flopped clumsily together and their hands tore and each other's clothes. The sweet, alcoholic taste of her breath filled Lincoln's mouth and the feeling of her hands pawing needfully at his crotch drove him wild.

Barely making it to Lincoln's room, they slammed the door closed behind them and stumbled to Lincoln's bed, their mouths and hands all over each other. Ronnie Anne pushed Lincoln back onto the bed and mounted him, pinning his hands above his head. She arched her back like a tigress stalking her prey and kissed Lincoln's lips. He kissed her back and rolled her onto her side. Their swirled their tongues together and stroked one another. Lincoln thrust his hand down the front of her shorts and plucked her folds with his middle finger, and Ronnie Anne clumsily undid his button.

They were so lost in one another that they didn't realize Lynn and Lucy had come into the room. Both were so drunk that the room spun and when they saw Lincoln and Ronnie Anne, they both froze. Sid and Stella, equally as blitzed, came in behind them. All four girls watched Ronnie Anne pull Lincoln's dick from his jeans and begin to stroke it. Lynn and Lucy were aroused even though Lincoln was their brother; at the moment, they were just drunk enough that that didn't matter as much as it would otherwise. Sid and Stella both blushed and panted like hungry dogs. Sid was the first one to move: She staggered over to the bed, flopped on, and started kissing Ronnie Anne's neck. Stella zeroed in on Lincoln's dick and followed, lying on her side behind him. She reached around and started to play with his cock while Ronnie Anne turned to Sid and started to kiss her. Lincoln lay on his back and Stella jacked him, slowly at first, then faster, encouraged by his oozing precum. Lucy's arousal overcame her and she went over, wedging herself between Lincoln and Ronnie Anne. She propped herself up on one arm and hovered her face over Lincoln's. His eyes and mind were hazy with drink and lust. Maybe he didn't recognize his sister. maybe knew who it was and didn't care; either way, he cupped her cheek in his hand and kissed him.

Lynn shook her head as if to dispel the vision before her then figured When in Rome…

Lucy and Stella took turns bobbing their heads up and down on Lincoln's dick while Sid straddled Ronnie Anne. Lynn sat on Ronnie Anne's legs, reached around Sid, and closed her hands over Sid's small but firm breasts. She kissed the side of Sid's neck and Sid threw her head back, relishing the butterfly touch of Lynn's lips against her throat. Lincoln pushed Stella onto her back and mounted her. Lucy helped him pull her panties down and held her skirt up to reveal her swollen pink pussy. Lincoln slid his hips forward and sank himself into her. Stella gasped at the sensation of his dick spreading her virgin walls, and Lucy licked her lips. "Can I be next?" she asked.

Ronnie Anne stuck her bare ass into the air and Lynn began to finger her. Sid spun Lucy around and they began to kiss. Lucy pushed Sid's shirt down her shoulders, exposing her breasts, and Sid stuck her hand up Lucy's skirt.

Going so fast that the bed shook and his balls slapped against her ass, Lincoln fucked Stella. Stella propped her legs in an M and clawed at his back, her lips fused to his pounding pulse and her moans coming out muffled. Before he came, he pulled out and aimed his dick away; ribbons of hot cum splattered Lucy and Sid, soaking their bare skin and dribbling down their quivering breasts. A bead of silvery jizz formed at the tip of one of Lucy's nipples and then fell like a fat raindrop to her lap, disappearing into her slit.

Lynn and Ronnie Anne furiously scissored, both red-faced and panting. Lincoln instantly got hard again and mounted Lucy from behind. She lifted her butt and he railed her pussy while French kissing Sid. Soon, Sid and Lucy were both on their hands and knees in front of him. Lincoln thrust into one, then pulled out and penetrated the other. He went back and forth, rutting Lucy, then Sid, then Lucy again.

The first one to cum was Lucy. Her walla tightened around him and her juices gushed out. He moved onto Sid, and in moments she was shaking and cumming too.

Finally, Sid and Ronnie Anne tag teamed him. Ronnie Anne rode his dick, bucking her hips wildly, and Lynn sat on his face, rubbing her pussy front and back across his nose and lips. They changed positions, each getting off multiple times. All of this activity had sent the alcohol sloshing through his system and brought him to the edge of passing out. He didn't know who he came in, but she squealed, thrusted her hips, and begged for more.

The next thing Lincoln knew, he was waking up in the middle of the night with a terrible headache and a nauseous stomach. Lynn and Lucy cuddled one side of him, and Stella and Sid on the other. Ronnie Anne was snuggled up against him, her hand and head both resting on his naked chest. A gentle smile graced her lips, and Lincoln ran his fingers through her hair. You might expect the night before to be a blur (if he remembered it at all) but it was crystal clear in his head. He knew he did some things that he would regret, but Ronnie Anne was positively not one of them.

Holding her close, Lincoln went back to sleep.

THE END.
