She's his submissive, but she is remiss in following instructions and has not performed her last tasks as she should have. He knows she needs discipline, so he picks her up, drives her to his high-rise apartment building, and escorts her to his 9th-floor condo. He has her stand before the large floor-to-ceiling window that covers one wall of his bedroom, and with the drapes opened, she can see the other high-rise apartment buildings all around. All have a perfect view into his bedroom, and of her, if they choose to look. He tells her his neighbors are always looking, and when they see something of interest, most have a telescope and camera set-up to make the most of their voyeuristic urges. And he knows they'll be looking this time because he let them know what he was going to do.
He tells her to strip, and being his submissive, she complies, taking her blouse and bra off, then her sandals, followed by her jeans and panties. She is nude now, but she feels so much more than just naked; she knows she is being observed from afar by unknown eyes. And he tells her that the men, and even some women, watching are expecting a show, and that he will be delivering one.
Grabbing her hands, he cuffs them and pulls them over her head, then secures them to a chain dangling from the ceiling. Next, he places a collar on each ankle, forces her legs wide apart, and secures her to a spreader bar. Now she is facing the window and helplessly restrained, looking at the many apartment balconies facing her, knowing that behind the windows at some of them, a man or woman has a telescope aimed at her, examining her body, her breasts and nipples, her thighs and pussy. He tells her that they can see her so close-up and clearly that they could count her pubic hairs, if she had any. She finds it scary, but also exciting, and she is getting aroused and wet thinking about being observed and helpless. In a final nod to her desires, he puts a blindfold on her, and she can no longer see the windows hiding unknown eyes... but she knows they are there, watching her every move. Then he tells her he will be back shortly and leaves her hanging naked in the window.
She waits, imagining all the eyes on her, and thoughts wander into her mind: what do they think of her being here? She begins to focus on the idea that she is exposed to his friends in nearby apartment buildings, who are ogling her naked body. The thought arouses her, and she is already very wet.

He returns after what feels like half an hour. She is glad to hear his voice as he tells her that he is going to play with her, but no matter what happens, she is not to let herself cum. The punishment if she does cum will be that he will leave her in the window for hours after he is done with her. And so he begins at her breasts, grabbing them, rolling and pinching her nipples, and pulling hard on them, stretching her nipples and breasts enough to make it hurt. She squirms and sighs with the torment, but she knows she is helpless and can do nothing to stop it. He is rough with her firm but sensitive nipples, making her eyes water with the pain he's causing, and getting her pussy wetter with unexplained arousal. When he stops after about five minutes of assailing her breasts, it is only momentarily, while, unseen by her, he takes a riding crop from a dresser.

He turns her around so her rear is to the window, then begins using the crop on her ass, striking her cheeks, one and then the other. He alternates for a bit, then begins to randomize his strikes, altering the timing and placement to keep her from anticipating the hits. Being blindfolded, every strike is a surprise, and he is swatting her hard, making her sigh in pain, squirm on the chain, and cry out. She can just imagine the voyeurs watching, using their telescopes to see her ass getting redder and seeing her struggle against the restraints holding her captive. As for her, the unseen crop is hurting, but also arousing her. She is getting wetter and craving a change of his attention to her pussy.
As if reading her mind, he stops hitting her rear and turns her around so she is facing the window. Then he begins swatting up and down each leg, randomly, to preclude any chance for her to prepare for the hits. He inches his way up her inner thighs and finally to her cunt, tapping her labia with the crop, and then uses the leather tip to spread her pussy lips apart. She is alive with arousal, her feminine juices beginning to flow as she feels so turned on, and knowing she is being watched makes it so dirty she can hardly contain her delight.
He begins to swat her pussy, and soon is smacking her clit. With some pain but a lot of arousal, any hope she had of not cumming is quickly vanishing with the joy of her predicament. She is squirming to his swats to her cunt, her clit afire with desire, her craving reaching intolerable levels. Her nectar is running from her cunt and dripping on the towel he had placed under her, and she imagines the voyeurs' arousal in watching her struggle to deny herself. As he begins to rub the leather tip over her clit, she cannot stand it any longer, and despite her attempts at denial, she cannot stop her pent-up urges. She cums intensely, swaying on the chain holding her hands above her head, writhing in pleasure, her juices flowing freely and falling to the floor as she moans so loudly she thinks the nearer voyeurs might even hear her.
He laughs as he continues to torment her clit, continuing her orgasm for several minutes of gasping, jerking, and spasming. When she is finally finished, she is spent and hangs by her arms, her legs unable to hold her up. He reminds her of what her orgasm means, aside from the pleasure she's had. It means she will be left standing in the window for all the neighbors to see, to ogle, to masturbate to, until he deems she's had enough and returns.
And true to his word, he leaves her hanging there, her rear still red, her nipples still sore, her pussy still wet. She hears the door close and lock while she remains behind, naked in the window, for all the world to see.
And she waits...
