Margaret's moans.

Upon hearing Margaret's name, Elmer was not scared but rather excited to lift up her nightgown. However, he was startled by her shivering body and found himself pressing his hand on her smooth buttocks with her black silk panties covering one-third of it.

Despite feeling the warmth of her buttocks and its slippery texture, Elmer dared not move his hand, fearing to wake her up.

After waiting for two minutes without any response from Margaret, Elmer cautiously removed his hand and continued lifting her nightgown. He then discovered a dilemma as her tight underwear clung to her buttocks, making it risky to remove them and possibly waking her up.

As Elmer pondered whether to continue, he noticed Margaret's eyebrows occasionally twitching, hinting that she might be dreaming.
