'Are you sure about this, _-chan?' Isane asked, looking dubiously at the soft lengths of red silk that twined around her arms, and the bedstead. Elaborate knots kept her arms secured to the bed at a comfortable angle, with her head propped up on pillows. Her feet fidgeted on the sheets.

'Are the bonds too tight?' you asked, running a gentle hand down her thigh.

She flushed. 'N-no, but, it's your birthday…'

You smiled, leaning forward on your hands to press a kiss to those full lips. You felt rather than saw the twitch of her arms as she automatically reached out to pull you closer, and was thwarted.

'You're the best present a girl could ask for, Isane-chan.'

Her large grey eyes widened, her cheeks turning a deeper shade of pink, but she smiled. Her stomach rose and fell rapidly, her pulse a nervous flutter at the base of her neck. Her knees were together, hiding herself from you, even in the soft light of the candles.

The bedroom was all muted gold light and forgotten cups of sake and your clothes strewn across the floor in disarray. Incense filled the air with a sweet, smoky scent. You sat back, wondering where to start. She was still a little tense, nervous at being vulnerable.

Where to begin? She was lovely, lithe, and statuesque.

You felt a smile curve your lips. She saw, and the blush crept down her neck toward her breasts, giving you a cue exactly where to start. You leaned over her, kissing her again. You melted together, your sigh of pleasure muffled by her mouth. You tasted her plump lower lip with a sweep of your tongue. Isane strained against her bonds. Her long legs tried to curl around your waist, pull you closer, but you pulled away, nuzzling at her neck.

Her chin tilted up. 'H-honey…' she stuttered, using the term of endearment she reserved for private moments like this. It was sweet to your ears. Soft kisses down the column of her throat had her shifting underneath you, her head turning side to side. 'You k-know what that does to me…'

Which was exactly why you did it.

Her breasts were begging for your attention, pushed higher by the way you'd tied her arms, nipples tight with arousal. You kissed the first swell of them, lightly brushing your thumb over a diamond-hard nipple. She gasped. Your kisses trailed down until your lips brushed the little bud. You opened your mouth and licked, slow.

'A-aah.'

Her little gasping moan was the only encouragement you needed to wrap your lips around the tip of her breast and suck. Her back arched, pushing herself toward you, offering herself up to your attentions. You hummed around the soft flesh in your mouth and stroked down her curving back, making her writhe.

'_-chan…' she mewled, knees falling open, rubbing restlessly against your sides. You switched breasts, wondering how long you could linger before she drove you insane. Each stroke of your tongue made her body twist in your arms, already running high on arousal. If only she knew what you had in store for her.

You finally left off and she flopped back to the bed, panting. Her stomach fluttered as you kissed and licked down it, heading for the apex of her thighs. You glanced up once you reached her hips. Her eyes met yours, not quite glazed, but instead dancing with anticipation.

'Happy birthday, honey.'

'Thank, you Isa-chan,' you purred, lowering your head, trailing hot kisses across her inner thigh. Her skin was soft and smooth as satin, growing warmer and wetter as you approached her core. Her breathing shallowed, hips shifting restlessly with anticipation.

Your tongue darted out to give her a quick, teasing lick. Then pulled back.

She moaned. '_-chan…don't tease.'

'I won't.' Your voice was full of dark promises. Her eyes flared wide. You were up to something. 'I bought myself a birthday present on my last visit to the world of the living,' you said, reaching to one side of the futon where a nondescript wooden box lay. You opened it. Inside, on a bed of silk, lay a long, smooth pink object. Too smooth to resemble a real phallus, but with a ring of soft bumps near the head. And a dial of controls at the base.

You took it out, weighed it in your hands.

'W-w-what is that?' Isane asked, voice high. She stared at the device in your hand. With a wicked smile, you press the on-switch. It buzzed into life with a happy little hum, the tip shaking just slightly. Her eyes became round, her mouth falling open. 'What are y-you going to do with that thing?'

You smiled, and ran the tip of it along the inside of her thigh. The vibration made her leg quiver, and she bit her lip.

'I'm going to play with you with it.' Slyly, you reached out a delicate finger and traced the damp pink slit of her sex. She stiffened, blushing. 'Here.'

'B-but…'

'Moan for me, Isa-chan,' you said, pressing the head of the vibrator to the underside of her clit. Lowest setting. For now.

A breathy cry ricocheted off the walls. She clutched at the silk scarves that held her, feet scrabbling across the bed. You watched her through half-open eyes, rubbing the vibrator in slow circles across her clit. Then you took it away.

'How was that?'

'I…I…' She panted, staring in consternation down at the device, then at you. 'M-more, please?'

'Anything for you, my love.'

You turned the vibrator up a notch and slid it back across her wet slit, rubbing her swollen clit. She arched, moaning, a line of sweat appearing down her torso. You looked down and saw her toes curl into the soft futon. Her reaction was so perfect, so sexy. You inched it down, pressing the slim device against her entrance, teasing. Her eyes popped open, her mouth opening to plead with you. You slid it inside before she had to ask, just an inch or two. Then out. Then in. Enter, retreat, enter, retreat. Slow as molasses, so she could feel every bump and vibration as it entered her, over and over.

Her first climax came as a surprise even to you. She tensed up, head falling back, sweet moans echoing around the small bedroom. You eased the shaft out of her, admiring the glisten on the soft rubber. She was soaked. You leaned down and licked the soft, slick flesh clean.

Isane gasped, hips lifting, twitching at the extra stimulation. 'H-honey, s-stop…'

'That's not the word we agreed on,' you murmured, sucking the swollen bud of her clit into your mouth. You'd agreed on a safe word beforehand, because you weren't going to tie up your sweet Isane without giving her some reassurance that she could say the word and be free.

She chewed her poor lower lip and glanced away. Silent.

You grinned. She didn't want you to stop. You wanted to taste more of her. Reclining on one side, you leaned over her hip. You kissed her, sucking softly, popping her clit in and out of your mouth. Clicking the vibrator up to the highest setting, you pressed it underneath her clit while you taunted her with broad sweeps of your tongue.

'_-CHAN,' Isane shrieked, feet digging into the mattress, hips fidgeting under you. You could hear her tugging at the restraints, a moan leaving her lips on every exhale. Her thighs trembled and her toes curled.

When her spine locked and every long line of her body was quivering with an intense orgasm, you pulled the vibrator away and slipped the length of it inside, twisting gently. A guttural, needy moan. Her skin slicked with sweat. She came again, the vibrator nudging and buzzing against her sweet spots.

Enough. You wanted it to be all you now. You eased it out of her and turned it off, lying down on your stomach between her thighs. Running your hands along the delicate skin of her inner thighs, you lapped at her, tasting. It wasn't sweet. She was a woman, not a candy bar. But it was Isane, and she was your acquired taste. A taste that you associated with her in raptures of pleasure.

Your name tumbled off her lips like a prayer. You glanced up. Her head lolled against her arm, lips red and swollen from biting, a flush high on her cheeks, short silver hair plastered to her face and neck. Her eyes were dark and glazed with pleasure. You winked up at her from between her thighs, then bent to taste her all over again.

When her moans turned to whimpers, and her thighs quivered under your hands, you gave a final, hard suckle that made her stomach visibly spasm. She came weakly, joints loose, body slicked with sweat.

'F-fishcakes…' she said hoarsely.

Immediately, you pulled away, sitting up. You reached for her face, stroking her cheeks. 'Okay, sweetheart,' you said. You reached for the knots and started to undo them. 'You were amazing.' Kisses along her cheek, a gentle one against her sore lips. 'Are you thirsty?'

She smiled faintly, giving you a nod. You reached for a glass of water and a damp cloth to clean the sweat from her limbs, the stickiness from her thighs. She drank it down and curled into your waiting arms, nuzzling into your neck.

'Happy birthday, honey.'

'It really was.'
