Up high on the topmost apartment's balcony, Tadao has a great view of the impressive skyline. His hands drum on the railing, and he enjoys the cool night air. The glass doors slide open silently.
'Thank you for walking me home,' Kimiko says, and comes closer.
She has changed into a flowery, silken dressing gown, and walks up behind Tadao. A lovely sight, Tadao marvels at her slim, petite body and perfect posture. The dark hair is done up artfully, held in place by a bright, colourful ribbon in the shape of a butterfly.
'The pleasure was all mine, Ms. Izumi,' he says. 'Your home is very nice.'
'The night's beautiful,' Kimiko says, joining Tadao in looking out over the city below.
Tadao turns to face her, and places his hand on her delicate cheek.
'It is,' he says.
'Cold though,' Kimiko continues, hugging him more closely, as though trying to huddle together for warmth. 'We should go inside. There is still something I need you to see.'
She pulls him by the hand, and he follows, posing no resistance. He is led straight through the spacious living room, and even right through the impressive bedroom, right to the very back, where another door is concealed behind a pair of red curtains.
Kimiko glances back at her companion's uncertain expression, and smiles confidently.
'Wondering what I have in mind? I hope you're curious,' she says, and with a click unlocks the door.
'I am,' Tadao admits.
'Not worried?' Kimiko turns to him, and touches his chest. 'You might run away when I let you in, when I show you what I have in mind.'
His eyes are on her shiny lips, soft, inviting, and she licks them slowly.
Tadao isn't quite able to keep up his calm, collected demeanour. He averts his gaze, and notices too late that his hands are trembling. Quickly he puts them into his pockets, and Kimiko laughs.
'Alright then,' she says and pushes down the door handle.
The walls are cold, naked stone, and the light from the ceiling is red. Tadao stares, confronted with a museum of medieval torture devices, heavy chains and decidedly exotic instruments, the likes of which Tadao has never seen before.
'Wow,' he says.
'I told you I had a surprise in store,' Kimiko smiles. 'So, what about it?'
She slings an arm around his neck, and gently brushes his ear with her lips, feeling the hair on his neck stand on end.
'You told me you were adventurous. Want to play, Mr. Watanabe?'
'Play?'
'Oh yes, we can have so much fun here.'
She tickles his stomach.
'All kinds of fun.'
Tadao swallows, then opens his mouth, but no sound comes out. He clears his throat, and nods hesitantly.
Kimiko's smile grows broader.
'You want to? I'm so happy, Mr. Watanabe,' she kisses him all over his neck and face.
Tadao blushes.
'I-if it makes you happy, Ms. Izumi... .'
'You know, you should really call me Kimiko now,' she says.
'Kimiko,' Tadao says out loud. 'It's a beautiful name. And you may call me-'
But Kimiko places a finger on his lips.
'No,' she says. 'Not tonight, Mr. Watanabe.'
She turns, and gestures towards a large, upright wooden frame in the shape of an 'x' or a crooked cross.
'Come,' she says, and walks up to it. 'How would you like to see me up there?'
Kimiko laughs, eyeing a growing bulge in Tadao's trousers.
'I'm not sure if I know how to... you know... .'
'Oh it'll come to you. Don't worry.'
Kimiko takes Tadao's hand and places it on her chest. He can feel the large, soft tits beneath the silk, and the nipples harden under his touch.
Kimiko unties her belt, and he brushes the light fabric aside. The gown slides off her shoulders, and falls to the ground. Tadao traces her feminine curves, pulls her closer by the waist. She nibbles his ear, before pushing him back a little, and shaking her head, mischief glowing in her eyes.
'Not like this,' she says.
Tadao takes a closer look at the frame. Although it is made up to look ancient, he can see that the dark wood is smooth and polished, and the metal shackles are shiny and intricate, with complex modern locks. On a small table next to the cross are Kimiko's toys, some made of leather, but also what looks like rubber, plastic and latex.
'Go on Mr. Watanabe. Which way round do you want me? Like this?'
She turns away from him, and spreads her legs. She slaps her bum, and the sound's echo rings on Tadao's ears.
The room isn't warm, but heat rises within him. He loosens his tie, and undoes his top button, then turns to Kimiko. Naked and eager, she stares at him unblinkingly, and as he looks at her heaving bosom a rush of excitement overcomes Tadao. He takes her by the shoulders, and pushes her, forces her back against the solid frame.
'Good choice,' she says.
Tadao crouches down beside her, and grabs one of her legs, strokes it, kisses it.
The first shackle goes around Kimiko's ankle. There is no key to be seen, but Tadao can hear a click as soon as he snaps it shut. First left then right, and Kimiko's legs are forced apart, two shackles around her ankles, two just above her knees.
Her face lights up, and Tadao can see her struggling against the restraints, her thighs tense, but unable to move one inch.
He rises to his feet again, and leans in for a kiss. Kimiko reaches out, feels his body under the shirt, one hand wandering down, lightly squeezing his erect manhood through two layers of cloth.
Tadao takes the hand, and guides it towards the shackle, so high above Kimiko's head that she can barely reach it. Another lock snaps shut. And another. The arm is held by the wrist and just above the elbow.
'You're doing great.'
Only one free limb remaining. Kimiko licks her finger. Tadao watches as she circles her nipple, takes it between thumb and forefinger, twists, and moans.
He takes the arm. Click. Click.
Kimiko cranes her neck, and puckers her lips, but cannot quite reach Tadao.
'Very good,' she says, straining with all her might.
Tadao pushes her back. Another shackle snaps shut around Kimiko's neck. Tadao puts his hand against her stomach. It is flat and hard, and he feels the contours of her abs, then pushes her torso back as well. Click. The last shackle just above her naval has closed.
'All helpless,' she says. 'What will you do now, Mr. Watanabe?'
A hunger in her eyes, Kimiko can only watch Tadao as he takes off his jacket, then his tie.
'So?' he asks. 'What is it you like?'
He grabs her tits, and begins to massage them.
'Pain?' he pinches the nipples, and Kimiko bites down on her lower lip.
'Maybe a little,' comes the breathy response.
'Being teased? Tickled?'
'Uh-huh.'
Tadao takes something from the table.
