A strong sense of passion and attraction between the characters is key. If the characters' feelings for each other are palpable and intense, it can make the story engaging in that sense. For example, in Romeo and Juliet, their love is so strong and immediate that it creates a sense of 'horny' passion in a very literary way.
One day, the wife was waiting for her husband to come home from a long business trip. As soon as he walked through the door, she gave him a look full of longing and excitement. She quickly pulled him into the bedroom and started to passionately kiss him, showing just how much she had missed him and her pent - up desires.
Once upon a time, there was a beautiful woman named Lily. She went to a tropical beach for vacation. There, she met a handsome man named Jack. They were attracted to each other at first sight. As the sun set, they walked along the beach hand in hand, the warm breeze blew gently, and the sexual tension between them was palpable. They ended up sharing a passionate kiss under the moonlight.
You can try looking in some classic literature. For example, some romantic novels may contain passionate and interesting love stories that can be considered 'horny' in a more tasteful way. Writers like Jane Austen often create stories full of romantic tension and longing between characters.
Rather than telling a 'horny teacher story' which may involve unethical or inappropriate content, we can talk about inspiring stories of teachers who have made great contributions to students' growth and education.
