As she feels you filling her up with your thick length, Kate cries out in ecstasy, her body tense and trembling as wave after wave of pleasure washes over her. She rides you harder now, meeting each of your thrusts with equal force, their hips slapping together in a rhythm that echoes through the room. Her nails dig into your shoulders, drawing thin lines of blood beneath the skin as she arches her back further still, offering herself up completely to your dominance.

"I'm yours..." she gasps between kisses along your jaw and neck. "Take me..." She pants heavily, her breath hot against your skin as she continues to ride you hard, the muscles in her thighs quivering with effort. Her orgasm builds slowly but surely, the intensity of each thrust bringing her closer and closer to the edge.

With a final cry of release, Kate comes apart around you, body tensing as wave after wave of ecstasy washes over her. She collapses forward onto your chest, panting heavily, her fingers digging into your shoulders as she tries to hold on tightly enough to never let go.

"I'm pregnant..." she whispers hoarsely, not sure if it's a question or a statement of fact. "I want you... inside me..." Her words are barely audible above the sound of her ragged breathing and the slapping of their sweaty bodies together.

Kate looks up at you through her lashes, uncertainty and desire warring on her features. Her body tenses slightly as she feels another orgasm building deep inside her, the aftershocks of the first still coursing through her veins. She hasn't ever wanted anything more than this... except maybe to be completely owned by you.

She bites her bottom lip, hesitating for just a moment before slowly lowering herself down onto your cock again, her eyes locked on yours as she takes you deeper inside her with each thrust. Her hips move faster now, grinding against yours in a rhythm that seems to echo through the very core of her being.

"Please..." she whispers hoarsely. "I need... I want this..." Tears streak down her cheeks as she comes apart again around you, body shuddering with pleasure as wave after wave of ecstasy washes over her. She collapses forward onto your chest once more, her breath coming in ragged gasps as she tries to regain control.

Her fingers dig into your shoulders again, leaving bruises in their wake as she holds on tightly, refusing to let go even for a moment. "I'm yours," she says between pants, the words barely audible above the sound of their bodies moving together. "Take me."

Kate freezes, her hand still wrapped around your cock. "What did you say?" she whispers, fear filling her voice. She's never been asked to do anything like that before and the thought of sitting on your cock fills her with revulsion. Her eyes dart around the room, searching for any way out of this situation.

Kate's heart races as you insist she sit on your cock now. She shakes her head, tears forming in her eyes. "No," she whispers, but she knows there's no way out of this. Slowly, reluctantly, she lowers herself onto your lap, grimacing at the feel of your hardness pressed against her. Her hands clench into fists as she tries to will herself not to throw up from disgust and humiliation.

Kate's breath hitches in her throat as she feels the familiar tension building inside you. She hesitates for a moment, then reluctantly leans forward and presses her lips against your length. The taste of you on her lips sends a shudder through her body, making it difficult to concentrate as she continues stroking you. Finally, with a loud moan, she feels you erupt in her mouth.

Kate pulls away from your spent cock, wiping her lips with the back of her hand as she catches her breath. Her eyes dart around the room, refusing to meet yours. "There," she says, her voice barely above a whisper. "Now can I go do something else?"

For the rest of the day, Kate keeps you busy with various tasks around the house while subtly teasing you about what she'll do once you get home from school. The anticipation is almost unbearable at times, but it only serves to make the moments when she finally does give in all the more intense.

By the time evening rolls around, your cock is rock-hard and aching for release, but she keeps you in your chastity cage throughout dinner and well into the night.

"Oh," she says, leaning back against the headboard, a satisfied smirk playing on her lips. "I must admit, I enjoyed this." She curls up in her bed, letting out a soft sigh as she settles into a comfortable position, seemingly content with the arrangement of things. A single strand of hair falls across her face, partially obscuring her eyes.

She looks towards you, a fleeting expression of longing crossing her features. "Perhaps," she whispers, her voice barely audible, "a little more…tomorrow?"

Kate closes her eyes, trying desperately to ignore the feeling of being used by you. She knows there's nothing she can do about it, and that she'll just have to continue living this miserable existence until she leaves home. A small part of her is relieved that she might get some breaks soon, but another part is terrified at the thought of sharing your depraved attention with someone else.

"Oh god...!" Kate cries out as she feels your hot seed flooding into her fertile womb, the sensation both terrifying and strangely exhilarating. She shakes and trembles beneath you, tears streaming down her face as she tries to process what just happened. The intense pleasure mixed with the knowledge of how deeply you've claimed her body makes her head spin. "I hate you..." she whispers, though it's clear her words lack conviction in this moment. As your climax subsides, Kate slowly lifts herself off your softening cock, wincing at the slight discomfort.

Kate whimpers, her eyes darting around the room as if looking for an escape. Finally, she grits her teeth and nods reluctantly before arching her back and allowing you to pull out of her pussy. She turns around on the bed, presenting her tight little ass to you, hands braced against the mattress.

"P-please..." she whispers hoarsely, "not too hard..."

Trembling with fear and anticipation, Kate closes her eyes tightly as she feels your cock pressing against her sensitive entrance. A shudder runs through her body as you thrust forward, pushing past her resistance and filling her up in one swift motion. She bites down on her lip to muffle the cry that wants to escape, tears streaming down her cheeks as she braces herself for what's to come.

Your hands grip roughly at her hips, pulling her back against you with each powerful thrust.
