I've never written erotic literature before, I did this on a dare. I'm sorry if it's not particularly erotic.
Koldo looked at her face over the table, she was saying something that was truly interesting, but he couldn't stop comparing the tiny differences between what he expected and what she turned out to be. It was like seeing the superposition of two people, a blurry overlay, an aura over the reality of her. And it was getting in the way, because she was so much more than he had imagined. Every tiny movement, the way her neck moved, her fingers when she gripped of her glass of beer, her eyes rolling under her heavy lids, caught him in a temporal vortex, stopping time and sucking him into a tiny eternity of attraction.
He had no idea how he had gotten in this situation. A random person, someone he never met, now was the entirety of his focus. An accident on the street, looking the wrong way, bump, accidentally placing his hand on her chest and dropping her book. He had no way of saying anything, once he perceived her. He never came back to himself. Whoever came back, it was not Koldo. Just his shadow, a mammal, his need.
