Dex wasn't exactly deaf. he's shut the water off, when he'd heard what sounded like something, or someone, hitting the way. Stepping out of the shower, he moved toward the door, listening. Yeah. He knew what they were doing, and it kind of made him angry and jealous at the same time. He liked Jax, liked her a lot. He was content being just friends, but really. He'd never seen this guy before, never heard of him. He was hot, sure, even Dex had to admit he'd do him, but he never thought Jax would bang him within hours of meeting him.
The hairs at the back of his neck and on his arms bristled. He had the vaguest sense that something wasn't quite right. Jax didn't seem distressed, but something. Dex knotted a towel around his waist and opened the bathroom door.
He was hardly prepared for the sight of Thomas' back, where he was riding Jax against the wall. "Get a room!" he said, figuring he'd play it off that he didn't realise what they were doing when he came out of the bathroom.
