The office door clicks shut, sealing in the soft hum of Ana's voice and the professor's low, encouraging murmurs. His hand, once guiding hers on the page, now traces the length of her arm, causing goosebumps to erupt on her skin. He leans in, his breath hot on her ear, "You're doing beautifully, Ana. Let's hear those beautiful sounds you make." His hand slips under her skirt, finding her panties damp with anticipation. Ana gasps, her eyes wide, but she doesn't pull away. Instead, she leans into his touch, her breath coming in short, soft gasps, filling the room with the sweet symphony of her desire.
