Describing women's moaning sounds in text requires careful consideration of context and desired effect. Avoid clichés and strive for originality. Here are several approaches, ranging from subtle to explicit:

Subtle & Suggestive:

• Emphasis on breath and rhythm: "A low, drawn-out sigh escaped her lips, punctuated by soft intakes of breath." This focuses on the physicality without explicit mention of moaning.
• Vague sounds: "A soft, throaty murmur filled the room." "A wave of sound washed over her, barely audible but intensely felt." These create an atmosphere of intimacy without graphic detail.
• Focus on the character's reaction: "Her eyes fluttered closed, a tremor running through her body. A sound, barely a whisper, escaped her lips." This emphasizes the emotional and physical response rather than the sound itself.
• Metaphor and simile: "Her pleasure was a low hum, vibrating through her." "A sigh, like the rustling of silk, escaped her." These use figurative language to evoke the feeling without direct description.

More Explicit (Use with caution and consider your audience):

• Onomatopoeia with nuance: Instead of simply "moan," use variations like "mmm," "ahh," "ooh," "ugh," or combine them ("mmmnnhhh"). Vary the length and intensity to reflect the changing levels of pleasure. Consider adding descriptions like "a low, guttural moan," "a breathy whisper of a moan," or "a sharp, high-pitched cry."
• Descriptive adjectives: Use words to describe the quality of the moan: "raspy," "liquid," "throaty," "strained," "whispered," "passionate," "ecstatic," "agonized." These add layers of meaning and emotion.
• Sensory details: Include details that enhance the experience: "The sound vibrated in her chest, a low hum that resonated through the room." "Her moan was a wave of heat, washing over him." This engages multiple senses.
• Build intensity: Start with subtle sounds and gradually increase the intensity and explicitness as the scene progresses. This creates a more realistic and engaging experience for the reader.

Examples:

• Subtle: "A soft, breathy sigh escaped her lips, deepening into a low hum that vibrated in her chest."
• More Explicit: "A low, guttural moan escaped her, building in intensity until it was a passionate cry, punctuated by sharp intakes of breath."
• Highly Explicit (Use with extreme caution): "Her body arched, a raw, animalistic moan tearing from her throat, a sound both ecstatic and agonizing."

Remember to always consider your target audience and the overall tone of your writing. Overly graphic descriptions can be jarring and detract from the story. The key is to find the right balance between suggestion and explicitness to create the desired effect. Experiment with different techniques and find what works best for your specific scene and character.
