Her heart skips a beat as you speak; she hadn't expected this at all. She turns back to face you, meeting your eyes with a mix of hope and uncertainty. "You would?" she whispers, her voice barely above a whisper. "Really?"

A slow smile spreads across her face, and she can feel the butterflies in her stomach growing wilder at the thought of what this could mean for them. Maybe... just maybe... they really could be together.

Her eyes search yours intently, her heart racing as she considers your words. She knows that committing to you means giving up on the idea of ever having a "normal" relationship with someone else; it means throwing herself completely into the fire and trusting that you won't let her burn. But at the same time... she can't imagine wanting anyone else.

With a shaky breath, she nods slowly. "Yes," she whispers. "I am willing to commit to this."

Her cheeks flush with embarrassment as he pushes her hand away and asks why she's doing this. She can feel the heat rising up from her neck and flooding her face, making it hard to think straight. All she knows is that it feels so good to touch him like this, and she never wants to stop.

She pulls her hand back slightly, but not completely away, leaving her fingertips just barely brushing against the head of his erection. "I-I don't know," she stammers. "

As she watches him struggle with his pajamas, Mei can feel a mixture of shame and arousal coursing through her veins. She knows she should stop what she's doing, but the feeling of having control over his body is intoxicating. Her hand slips back between their bodies, wrapping around him firmly as she begins to stroke him faster and harder.

"Please..." she whispers, her voice barely audible above the sound of skin on skin. "Just let me... touch you."

Her breath fans across his neck as she begins to trail soft kisses along the column of his throat, her fingers digging deeper into his skin with each passing second. "Oh, don't worry about that," she whispers against his skin, her voice husky and low. "I know just how to make you feel good."

Her free hand slides down his chest, tracing lazy circles around his abdomen before reaching for the button of his pants.

As she undoes his pants and pulls them down along with his boxers, Mei can't help but feel a surge of power coursing through her veins at the sight of his arousal. She takes him in hand, stroking him slowly as she leans in to kiss his neck once more.

"You know," she whispers against his skin, "I could make this arrangement permanent if you wanted." Her fingers begin to move faster, circling around the head of his cock with increasing pressure. "

Her breath comes faster and her eyes squeeze shut as she feels the pressure building inside her again. With a loud moan, she comes undone beneath you, arching off the bed and gripping your shoulders tightly as wave after wave of pleasure washes over her. Her body trembles with release, every muscle tensing and relaxing in time with each thrust.

Her cries of pleasure fill the room as you continue to thrust into her, your cock twitching inside her with each stroke. Her body quivers and shudders beneath your touch, her orgasm seemingly endless as she's lost in the sensation of being so completely connected to you.

Finally, her breath slows and she collapses back against the bed, spent and satisfied. Her eyes flutter open and meet yours, glistening with pleasure and desire as she pants to catch her breath. "That was..."

Mei lets out a contented sigh as you continue to massage her back. "Mmm... that's nice," she murmurs, closing her eyes and savoring the sensation of your strong yet gentle hands against her skin. "You can keep going if you want..." She trails off, not quite meeting your gaze, her heart racing faster with each passing moment.

She tries to focus on how good it feels rather than where your hands are or what they might be doing. It's hard though...

As you continue to massage her back, Mei lets out soft moans of pleasure. It feels so good... better than anything she's felt in a long time. She tries not to think about how close this is becoming to something more intimate, but it's hard when your body responds so strongly to the touch.

She closes her eyes and lets herself enjoy the sensation for what it is - a sweet gift from her brother who cares enough about her to make her feel better. "Mmm... that's nice..."

Her words come out in broken gasps as you continue to thrust inside her, driving her ever closer to the edge of release. She nods, unable to speak coherently, trying to focus on your questions instead of giving into the pleasure that's taking over every inch of her body. "Yes... fertile..." she manages to croak out between moans.

Her hips buck wildly against yours as you hit a particularly sensitive spot deep inside her, sending shockwaves of pleasure coursing through her entire being.

Her muscles clench tight around you as she feels your hot seed spill deep inside her. With a throaty moan, she arches her back and throws her head back, letting out a shuddering cry of release. Her body trembles with the intensity of her orgasm, waves of pleasure washing over her in endless succession.

As she comes down from her high, she feels a mixture of relief and guilt wash over her. She's never felt so good...
