"Tell me one of the fantasies you used to have about us," Brennan murmured, lazily stroking Booth's bare chest as she laid beside him. His arms were up, and his hands were resting beneath his head.

It was hot—almost too hot for sleeping, even with the air conditioning on. The heat made their bodies seal together slickly, and made everything very lethargic. Booth didn't move at her question, but one of his eyebrows quirked up in slight surprise.

He grunted softly, as if considering, and Brennan slipped closer to him, letting her entire hand smooth across his pectoral muscles. "I assume you had some," she added as her thumb lazily rubbed against his nipple.

His second grunt was more of a laugh, resigned and amused, but also sexy. "Uh, yeah…" he acknowledged with a smile, turning only his neck to meet her eyes. Brennan felt almost shy all of a sudden, but she didn't back down.

"I…" she began before swallowing and flushing a bit, her own smile curving up her lips. "I would like to know them."

Booth's eyes narrowed and his lips pursed for a second. Gently he lowered the arm farthest from her and cupped her elbow in his fingers. "Fine, but you gotta tell me one of yours, too."

"Fine," she breathed quickly, unable to hide the excited tone in her voice. "I…will do that."

"Fine," he repeated. "Right," Booth turned to his side, suddenly facing her from nose to toes. He was smiling, and his eyes were still narrowed, but this time not in suspicion, just sleepy arousal. His lips brushed against hers once, then again. "Okay, here's one," he paused when her eyes flashed at the knowledge that there was indeed more than one. Oh, Bones…

"Do you remember when you gave me a key to your pool?" he asked, letting one of his hands cup against her bare thigh.

"Yes," she answered. "Of course I remember. It would be very irresponsible for me to forget who I loan keys to."

Booth ignored that and continued. "Well, I know it was meant to be a nice gesture for Parker, but I um…you know, I sort of wanted it to be a gift to me, too, right?"

Brennan traced his thumb with hers and nodded. "It was…"

"Yeah, I know that now," Booth told her and placed another soft kiss on her lips. "But at the time," he said as he moved back to his pillow. "I don't know…I kind of liked the idea that, you know…maybe I'd surprise you, or something like that."

"You'd…surprise me," Brennan clarified, feeling as if she wasn't quite getting the point. "What does that have to do with having the key to my pool?"

His neck flushed a light red, and he smiled. "It would be late at night, and no one else would be around, and you'd be swimming, and I'd arrive, alone, and it would just be the two of us."

"In the pool," she wanted to make sure she had the facts straight. "And…that's it? We just…swim?"

Booth laughed. "What do you think?"

Brennan laughed too, and this time it was her that leaned over to place a kiss on his mouth. She lingered, enjoying the feel of his lips against hers. She let her tongue slip against his bottom lip, and when he moaned and tried to deepen the kiss, she pulled back. "We could do that right now," she offered in a low, seductive voice.

But Booth wasn't thinking about that any longer. "Kiss?"

"No, Booth," Brennan sat up enough that her pale breasts gently swayed, pale and pretty. "We can make that fantasy a reality, so to speak."

"Bones," Booth shook his head. "What?" His eyes got wide when she smiled and slipped away from him. He watched as she got up off the bed.

"Come on, Booth…let's go swimming."

"No," he insisted, patting the bed beside him. "Bones, be serious…" When she walked over toward her dresser and pulled out a skimpy bikini, he nearly choked. "You're serious? You're serious."

Brennan spared him a sly glance over one shoulder as she bent down and pulled the flossy bikini bottoms up her long smooth legs. Booth growled low in his throat at the gentle spread between her thighs, barely covered with the scrap of emerald green fabric.

"This is crazy, Bones," he shook his head. "And illegal. You know that, right? Apartment complexes…they have rules for this kind of thing. People can't just go around having sex in public pools, Bones."

She smirked at him and faced him, nearly laughing when his eyes narrowed on her bare breasts. She did laugh at the way his face pinched in instinctive frustration when she covered her breasts with the bathing suit top. "Is that argument part of your fantasy too?" she teased, and at her words, his eyes shot up to meet hers. When he didn't say anything, she had her answer.

"I'm going swimming, Booth," she turned and walked toward her bedroom door. "Join me if you wish."

Booth watched as she went and then looked down to see where his fresh erection was currently tenting the sheet over his waist. "I don't even have swim trunks here," he called out loudly.

"By the sounds of your fantasy, you likely won't need them," he heard Brennan call back before he heard the sound of the closing front door.

With a grumble, he shoved the sheet from his legs, yanking off his socks with it. Cursing a bit, he stalked around the bedroom until he found his boxer shorts from before. They would have to do, but they'd be no use to him afterward unless he tossed them in her dryer. He pulled them on and ran a hand through his hair before padding to the bathroom to grab a towel. He paused when he saw his reflection in the mirror—tan skin, a couple of red marks near his neck from when Brennan had kissed him along with her orgasm, a few scratches near his hips and a hard-on tenting the front of his boxers. "Great," he sighed and pulled a towel from her linen closet, keeping it close to his waist in case he ran into anyone else on his way down to the pool.

He was lucky, and it was completely abandoned, save for one gorgeous pale line of perfection in the water. As he stood at the gate and watched her swim, he remembered several nights, and his past fantasies began to merge with the reality. Sometimes he would imagine watching her, seeing her sexy curves caressed with lapping water. Sometimes he'd imagined her rising out of the water, her hair streaming down her back and drops of water racing over her from head to toe. He'd imagine her spotting him. Her eyes would flare in surprise, maybe a hint of fear (which always made him a little bit harder) and then arousal, and always a smile, as if she'd been expecting him. It was that knowledge, combined with the reality, that made him finger open the gate's latch.

It creaked a bit, loud enough for Brennan to hear it. She paused and pressed her palm to the rough edge of the pool. The moon was bright, even in the city, and from her position in the pool, Booth seemed taller, stronger, darker and more male than ever. Her eyes traced down his body from his head to his bare feet. "What happens next?" she asked, and his eyes flared.

Without a word, he set the towel he'd brought on a nearby chaise. Her eyes never left him as she watched his firm hands wrap around the pool ladder rails. She noticed the way he hissed a bit when his feet were submerged in the water. She didn't hear it—she just saw it in the way his stomach barely flexed. Neither of them said a word as he slowly sank into the water. It came up to just below his chest, and Brennan watched as he walked toward her.

"Fancy meeting you here, Bones," he said softly, one side of his mouth curving up with a smile.

Brennan blinked for a moment, unsure why he would say that. Then she realized it was part of his fantasy. Whatever he'd imagined for them involved the camaraderie they often shared.

"It is my pool, Booth," she commented, and his smile widened.

"True," he conceded. "You don't mind that I came over…"

"No," she answered quickly and ignored the breathy tone in her own voice. "Of course not."

"I mean, it's kinda hot out." he added.

"Of course," Brennan acknowledged. "I'm glad you're here."

Surprise flared in his gaze, and it warmed suddenly. Brennan felt a chill course deliciously through her body, and her nipples tightened. As if on command, Booth's eyes flickered to her breasts, and she watched as his jaw tensed. He didn't look away, and his fingers began to gently swirl in the water near his side.

Brennan followed the line of his arm up to his shoulder, and then she let her eyes roam over his broad chest, down to the trim waist at the water line. Over the years she'd known him, she hadn't seen his bare chest very often, and with it nearly within touching distance, she was finding it hard to resist. He was all smooth skin and rippling muscles. She wanted to taste him…right where his shoulder met his collarbone.

"I'm surprised no one else is out here," Booth commented, sinking down into the water until it was up to his shoulders. He stretched out his long arms for balance and rested on his upper back. Brennan liked the way his skin looked against the water…the dark of the sky reflected in the water, and the glimmer of the moon reflected on his body.

"Really?" she murmured, feeling connected to him.

"Sure…" he shrugged a shoulder and little drops of water fell down his chest. "It's hot as hell, Bones…I kinda figured there would be a lot of people out here…trying to sneak around."

Brennan gave a small smile. "For sexual liaisons, you mean?" She figured he'd roll his eyes or shake his head and flush. But instead, his eyes only grew darker, and his tongue flicked out against his bottom lip.

"Maybe. Gotta admit it's pretty sexy," was all he said, and Brennan had to turn away to keep him from seeing the smile on her face. She knew he hated when she talked about sex if other people were around, but lately, he seemed to be joining in whenever she brought it up. Turning her head to look over her shoulder, she watched him rise in the water and walk toward her. Immediately, she trembled, her bikini feeling less than adequate to cover her skin.

She imagined him using his long and blunt fingers on her, slipping them under her suit to her bare skin. Her nipples pebbled, both in anticipation and in the slight chill in the air compared to the water. Suddenly, she felt water all along her back, and she whirled around in surprise.

Booth smiled, his grin boyish and sexy at the same time. Brennan retaliated with a splash of her own, forcing her hand through the top surface of the water for maximum spray action.

Booth laughed and dodged her attempt. Brennan huffed and used more force, but was thwarted again when Booth sank completely into the water, effectively evading her splashing him. She stomped her foot on the pool floor, and then gasped when Booth rose from the water, only inches away from her. He was like a Tritan, all bare skin and rippling muscles. Water dripped from his hair and shoulders, and his eyes flashed with flirtation…so dark and so sexy. A feminine laugh of anticipation rose from her throat, and when he grinned, she nearly squeaked and moved to the side, out of reach of his arms. Booth laughed and caught up to her, wrapping one strong arm tight around her waist. He tugged her to him and pressed her flush against his body. His lips were sensually curved, and his eyes hooded. Brennan gasped and her eyes focused on his mouth. It was so close to hers, and she could just imagine what it would feel like if he kissed her.

Just when she thought he might, she tasted water. She blinked and sputtered and hissed. Booth just laughed and splashed her again as he swam away. Brennan growled and swam after him. He was easy to catch, though she supposed he wanted to be caught. There was something about this night—the open air and empty pool—that allowed them to be more free than normal.

She pressed on his shoulders and tried to force him under water. He barely budged, so she pressed harder. He just laughed at her, and then he wrapped his arms around her waist and in a flash, disrupted her center of balance when he let his feet move from the pool floor. They both fell back into the water, and Brennan wrapped her arms around Booth's neck for support. When she rose out of the water, she used one hand to smooth her wet hair away from her face, and Booth's fingers were tangled in the flimsy knot at the nape of her neck. Brennan blinked, and then the front of her bikini was loose over her breasts.

One side of Booth's mouth curved up in the slightest of smiles. "Oops," he murmured, though nothing about him seemed regretful at all. Brennan played it cool and easily peeled the now worthless fabric from her body. She let it float away and enjoyed the way Booth's eyes widened with surprise. She watched his throat work as he stared at her face for just a second before his eyes fell to her breasts and firm, tight nipples.

"I enjoy the feel of the water on my bare skin, Booth," she commented coolly, noticing the way he nodded, but didn't look away. "If you can go topless, so can I."

His eyes did flick up to hers then, and he smiled. "Guys don't go topless, Bones…it's just…" he shrugged a bare shoulder. "It is what it is."

Brennan didn't answer him but just moved away from him. His eyes narrowed immediately, and he followed after her. She laughed and swam to the other side of the pool. Booth was quick behind her, but she stayed out of his reach, darting from one end to the other. When she reached the pool's ladder, she gripped the metal bars and began to rise up.

Booth grasped her hips from behind and stopped her, pressing his chest against her back. "No way, Bones," he cupped her hips and pulled her back into the water. "You're not going topless for anyone but me."

Brennan didn't answer, just turned her neck to look at him over her shoulder. His eyes were serious, and when he leaned toward her, she met him halfway. Her hands were still wrapped around the ladder, and she squeezed the cool metal when their lips met and his hands slid up to cup her bare breasts at the same time.

"Oh," she breathed against his mouth, the feel of his wet fingers against her slick breasts, combined with the warm press of their bodies and the sensual anticipation of the night made sensation spike from the tips of her breasts down to her clit. Booth's long fingers played with her nipples as his tongue rubbed against hers. Brennan began to move her hips in invitation and Booth kept his feet planted as he rocked his hard erection against the curve of her bottom. "Are we doing this?" she asked, and he groaned, running one hand down to cup her hip.

"Yeah," he gasped. One of his feet settled between her legs and he spread her apart. Brennan clutched onto the ladder for support and let the rippling water hold the rest of her weight. She was suspended and felt weightless, anchored by the feel of Booth's body behind her. He easily fingered her swimsuit aside and freed himself. In one move, he spread her wider and slid inside. The water allowed for an incredible angle, and Brennan moaned as her chest and upper body fell forward toward the water. Her breasts brushed against the water, and the lapping waves rushed over her curves and nipples in gentle caresses. His upper body pressed into her lower back with every thrust up into her body.

With one arm, he held her around the waist, and with his other hand, he made small waves under the surface of the water…each one designed to run water with extra pressure against her exposed clit. Each move of water caused Brennan to gasp, and she clenched the ladder rails so tightly that her knuckles went white. Their movements caused loud splashing sounds, but neither noticed over the pleasure coursing over their bodies.

"Booth," she cried out. "This is…"

"Yeah," he agreed and pulled out of her quickly, flipping her around and forcing her arms around his neck. Brennan plastered herself to him, immediately pressing kisses against his jaw and chin. Booth moved until he was pressing her back against the pool wall, and he moved them along until he felt the single water jet. He wrapped Brennan's legs around his waist and positioned them again, letting the jetting water stroke along her slit as he rubbed the head and length of his cock along her clit. "Fuck, Bones," he panted out. "You have no idea how much I wanted this. How much I wanted you." All pretense was gone, and he was stripped bare. "I used to dream of catching you here. Touching your wet skin and just…" he pulled her tighter and his neck tensed as his mouth fell open with pleasure. "That damn key…taunted me, Bones. I wanted you. I wanted this," he rocked against her.

"Ah, ah, ah, ah, ah," she panted and writhed and buried her fingernails into his shoulders. Booth hissed but didn't stop until she came. Brennan pressed her face to his neck and rode him up and down until the shattering climax settled to soft pleasant waves. Only then did Booth bury himself inside of her. He gave three short thrusts without leaving her tight core, and then he came—hot and hard and deep.

His voice was low and he cursed and growled and shuddered. As her pleasure subsided, Brennan noticed the way the pool wall scraped against her back in contrast to Booth's smooth chest. She used her tongue to lazily trace a drop of water against his shoulder, and he gave a satisfied little whimper that made her smile. He kept her wrapped around him and used one arm to swim over to where her bikini top had floated away. Booth smiled down at her and kissed the tip of her nose as he helped her slide back into it. She shivered as the cold material hit her bare skin, and he laughed and kissed her lips.

Quickly, they left the pool and wrapped up in their towels. Booth grabbed Brennan's hand and they both laughed huskily as they made their way back up to Brennan's apartment. By the time they reached her bedroom, they were both shivering and diving for the covers.

Brennan snuggled close to Booth and laughed when he yelped. "Cold feet, Bones! Jeez!"

She smiled again as she kissed his neck and jaw. Booth exhaled as he settled down, and Brennan kissed his cheek and then his lips. "I have a confession, Booth," she told him, quickly kissing him again.

"Oh yeah?"

"Yes," she traced his chest and enjoyed the way he smiled. "That was a fantasy we shared. I used to dream about it too."

His smile grew, and turned to face her, burrowing deeper under the bedspread with her. "Well, great minds think alike, I guess."

"I guess so," she wrapped one arm around his waist and snuggled close to him for warmth.

"But," he murmured as both of them began to fall asleep. "That so doesn't count as you telling me one of your fantasies. You owe me one, Bones," his lips nuzzled into her hair in a lazy caress.

"Okay," she agreed, her tired mind thinking of a few sleepy scenarios.

But they would have to wait until another night.
