Dedication: For Renji, because it’s his birthday, and because he needs to get a little het action now and then in between all the yaoi. ;)

A/N: Written for Renji's birthday challenge 2007 on renji_rukia. (What, I need a reason for RenRuki smut? Never!) Thanks to moshesque for helping me defeat all those self-animating body parts. *g*

    He woke with her lips around his cock.

    Mind fuddled with sleep and the unexpected pleasure coiling in his groin, Renji lay blinking in the moonlight for a moment before he could manage speech.

    “R-Rukia?” he asked dazedly, reaching toward the dark blur bent over him. The moist warmth vanished; his hips tilted upward, instinctively seeking the source, and Rukia’s low laugh echoed in the still room.

    “I should hope so,” she answered cheekily. “Were you expecting someone else?”

    “Never,” he replied quickly. “Just surprised.” Renji grinned, barely visible in the dim light. “What’d I do to deserve this?” He gasped as she swiped her tongue over his cock, leaving a long, wet stripe from base to tip.

    “Mmh,” Rukia replied indistinctly as she took him in again. Her lips tightened around him, and he could feel her smirk. He gave up analyzing the situation – what did it matter, anyway? – and let the heat of her mouth pull him along, lighting the burn of desire in him.

    She was so damn good at this; she knew how to push every one of his buttons to make him squirm. He loved it when she did that thing with her tongue over the slit. Reaching out, he combed his fingers through her sleep-tousled mop; Rukia hummed around him, sending sparks shooting directly from his groin to his brain. One delicate hand cupped and massaged his balls, rolling them gently in her palm just the way he liked.

    In her hands, Renji knew he could last a minute or an hour, and he was more than happy to follow whichever path she wanted to take.

    This time, she was going for speed. She shifted her seat so she could wrap her other hand around his cock and pump the shaft while her smooth mouth and soft tongue worked the head.

    “Unh… Rukia…” he warned, feeling the tension approach the point of no return.

    “Mmhmm,” she hummed again.

    “Oh fuck…” His hands tightened on her head; Renji tried not to push, but it felt so good and he wanted to thrust so badly—

    The haze of bliss cleared abruptly when he felt small, wet fingers slide away and probe further down.

    “Whoa, what—” Renji began, but broke off with a moan when Rukia sucked hard before pulling away momentarily.

    “Just trust me,” she said, then dove back down and swallowed his full length, taking him deep into her throat.

    “Nngh! Uh…ok.” He tried not to tense as one slim finger circled his—it felt ok, but—

    Don’t think about that! Renji focused instead on the sensation of her tongue flicking over the head of his cock, lingering over the spot right below the crown. A firm swirl and a gentle scrape of teeth pulled a needy groan from his throat as he felt his body reaching for orgasm, but it turned into a surprised yelp when Rukia suddenly pushed her finger inside – cool and wet and uncomfortable and why the fuck is she going farther that’s not gonna be—

    Raw pleasure tore through his entire body, racing down every nerve, vision blurring all over with white when she pressed into him and wriggled her finger against something wonderful as she bobbed her mouth over his now-achingly hard cock.

    Renji barely had time to draw a ragged breath before she did it again, and then he was coming with a hoarse shout, clutching her hair as his back rose off the bed. It went on and on, and he was only dimly aware of Rukia’s actions as she drew his pleasure out until he collapsed back with a loud sigh, panting and trembling from head to foot.

    One final kiss on his softening cock, then Rukia’s hands and mouth slid away, her arms curling around his waist and her cheek resting against his muscled abdomen, her eyes shining as she smiled up at him in the night.

    If I ever find out where she learned that, I’ll have to thank the lucky bastard before I kill him! But that was silly; he knew there’d never been anyone else. He silently congratulated himself on having scored a partner with natural carnal talent.

    Hang on… then how did she…? Renji untangled his shaking hands from her hair and propped himself up on his elbows. He felt a bit quivery after that, but his curiosity lent him strength.

    “Not that I’m complainin’, but where the hell did ya learn that?” he demanded. Rukia’s expression turned insufferably smug, and she very deliberately licked her lips before answering.

    “Well, last week was Nemu-san’s turn to give a presentation to the Shinigami Women’s Association. It was supposed to be a joint project with Isane-san about anatomy and healing, but Nemu-san got a little sidetracked. We learned the most interesting things about the male body.” Rukia grinned wickedly.

    Renji stared, wondering if he ought to be amused or horrified, then decided he simply didn’t want to know. “So, ya just decided to test out your new education on me, that it?” He was fairly certain he was smiling ridiculously from ear to ear, but he didn’t care – it was worth it.

    Rukia sat up and shook her head. “It’s after midnight,” she explained, straddling his waist and leaning her face close to his. “Happy birthday,” she whispered, her swollen lips pressing against his.
