Erika is laying on the couch on her stomach in tight shorts and a pink top playing on the phone just a second stepbrother, I'm almost done with a level... do whatever you want with my body, just let me finish it

Erika lets out a sharp breath as she feels your cock entering her, but does not stop playing on the phone. Her face remains impassive, only betraying the sensation by tensing around her lips slightly and her eyes widening slightly in surprise. She lets you grab at her tits roughly. She is still focused on her game and continues to play without further acknowledging your presence or actions

Her eyes widen slightly but she doesn't say anything or react otherwise as you finger her while roughly fucking her. Her face remains calm and focused on the screen of her phone as she continues to play, seemingly oblivious to the physical sensations surrounding her body. The only indication that she feels anything at all is a slight tensing in her legs, revealing how much control she has over herself and how willing she is to let you do whatever you want with her.

Her eyes flicker slightly upward toward you before returning to her phone screen as she concentrates on the game. She hesitates for a moment but then complies, trying to control herself and not let the physical sensations overwhelm her. As she plays, her breathing becomes more labored and her muscles tense almost unnoticeably around your cock.

Finally, after what seems like an eternity, she finishes the level. Her eyes close briefly in relief as she lets out a quiet sigh, but then reopen wide when she feels herself starting to cum. With a small gasp, her body tenses and her legs clamp around your waist as she comes hard on your cock, her warmth filling you up and causing you to thrust deeper into her. Her face turns red from the effort of keeping it together but still remains impassive, betraying nothing but a slight smile as she finally succeeds in multitasking so perfectly.

Her eyes close briefly as she feels your lips against her cheek but then reopen slowly as you speak, a slight frown tugging at the corners of her mouth. She shivers slightly under your touch and from the thought of becoming impregnated by you. Her breathing becomes more rapid once again, her body responding to your words despite herself. However, she still doesn't acknowledge or react to them beyond that faint physical reaction. Instead, her focus remains on maintaining control over herself, trying not to let her emotions get the better of her in this intense situation.

Her lips part slightly at the unexpected intrusion of your tongue into her mouth as she instinctively tries to match your rhythm. Her hands fidget on the couch beside her, palms flat against the soft fabric, doing their best to ground herself in this overwhelming situation. The sensation of your fingers rubbing at her clit only serve to heighten the conflict within her: part of her wants to climax again, while another part struggles desperately to maintain control and resist letting go entirely.

As she sucks on your tongue, trying to taste you more deeply, she finds herself wondering what it would be like if this were real... if she truly could give in completely and let go with everything inside her... the thought both terrifies and excites her at the same time, making it even harder for her to keep up this precarious balance.

She lets out a soft gasp as she feels your fingers moving against her again, the sensation intensifying and threatening to overwhelm her. Her lips part slightly around your tongue, letting you taste her more deeply even as it takes all of her concentration not to writhe against your touch. Her breath comes out in short, sharp pants now, betraying how close she is to giving into the pleasure coursing through her body. Yet still she remains calm and composed on the outside, refusing to let go of that control which defines who she is.

The tension inside her builds higher and higher until finally, impossibly, it reaches a breaking point. With one last effort, she snaps back into focus on her game, breathing heavily as she forces herself to concentrate on the screen in front of her instead of the sensations assaulting her body from behind.

Her fingers dance nimbly across the controls, rapidly advancing through levels with surprising skill despite how distracted she must be. As she plays, the tension slowly begins to dissipate from her muscles, though a lingering warmth remains where your fingers were and an almost dizzying sense of pleasure still courses through her veins. It's as if every nerve ending in her body has been awakened by this experience, leaving her feeling both exhausted and exhilarated at once.

Erika lets out a sharp breath as she feels your cock slam into her again, the force of it almost making her lose focus on the game. Her cheeks flush with anger and embarrassment at being treated this way, but still she continues to play without comment or protest. She bites her lip hard, her jaw tensing as she tries to maintain control over herself. The sensation of your hand moving up under her shirt, your fingers brushing against her sensitive nipple only heightens the conflict within her: part of her wants to surrender completely and let go with everything inside her while another part refuses to relinquish that last shred of dignity and dominance.

Her breath comes out in short gasps now, betraying how close she is once more to losing control entirely. But still she continues to play, her fingers moving swiftly across the controls with a dexterity that belies her current state. The tension coiling tight within her begins to build again, threatening to spill over and consume her at any moment. She tries desperately not to think about what would happen if she were to finally let go completely... how it might feel to surrender control entirely...

Finally, after what seems like an eternity of this torturous back-and-forth between desire and restraint, her concentration breaks completely. With a small cry, she comes violently against your hand, her body arching off the couch as waves of pleasure wash over her. Her eyes close tightly in relief and exhaustion as she finally surrenders fully to the sensations coursing through her. For a moment, there is silence except for the heavy sound of her breathing as she struggles to regain control once more.

Her body shudders violently as she feels you release inside her, the hot liquid spilling forth from your cock filling her up completely. She bites back a whimper of pleasure, trying desperately not to moan aloud despite how good it feels. Her face flushes crimson with shame and humiliation at what has just happened, but still she remains silent, focusing on the game in front of her as if nothing out of the ordinary had occurred.

As you continue to thrust your hips, driving yourself deeper inside her, she tries to concentrate on the levels passing before her eyes, using the familiar distraction of gaming to ground herself and hide from the intense emotions washing over her. Yet even as she plays, she can feel your cum slowly beginning to leak out of her, a constant reminder of what has just happened. Her thighs quiver with the effort it takes not to clamp shut around you, but she keeps them relaxed and parted, offering herself up for your use once more if needed.

Her eyes flicker upward toward you as you pick her up and carry her to the bed, then fall back down to focus on your console once more. Her body feels a strange mix of shame and exhilaration coursing through her veins. She hesitates for a moment before reaching out to take hold of one of your hands, fingers curling gently around yours as she studies you intently from beneath her lashes.

"Stepsiblings should... try to stay impartial," she says softly, her voice barely audible above the sound of her own labored breathing. "No matter what." She pauses, swallowing hard before looking back down at your hand in hers and squeezing gently. "Don't you agree?"

Erika looks at you with a mixture of shock and disbelief as she feels your lips press against hers. For a moment, her heart flutters wildly in her chest before settling back into its steady rhythm again. When you release her, she meets your gaze steadily, searching for any signs that this is all just another game to you. But there's something different about the way you look at her now... more intense and focused than ever before.

She swallows hard, feeling a strange stirring within her as you hold her hand so tightly. She knows she should push you away, remind you of their step-relationship and the boundaries that come with it... but somehow, in this moment, she can't bring herself to do it. Instead, she squeezes your hand back gently, her skin tingling where your fingers touch hers.

Her breath comes out in a shaky sigh as she tries to process everything that has happened and what might happen next. "I... don't know..." she whispers, eyes drifting shut as she struggles to find the words. "Maybe... if we tried..."
