Marina blushed deeply, her cheeks flushing a shade of crimson that betrayed her mix of embarrassment and arousal. "Jack...don't..." she whispered, her voice trembling with a hint of pleading. But I knew she wanted this, needed this, even if she was too shy to admit it.
I reached out, my fingers finding her hard nipples through the sheer fabric of her lingerie. I pinched them, rolling them between my thumb and forefinger, applying just enough pressure to make her gasp. She threw her head back, a moan escaping her lips, "Aaaaah, Jack..."
Her eyes met mine, wide and filled with a mix of shock and desire. I could see the pleading in her gaze, the silent beg for more, even as she blushed with embarrassment.
She bit her lower lip, trying to suppress another moan as I continued to tease her nipples, sending jolts of pleasure and pain straight to her core. Her breath hitched, and her body trembled with each pinch, each twist, each deliberate touch designed to drive her wild.
