Tristan wasn't really aware of Sev's inner thoughts nor would he have guessed at them. He never thought twice about telling her of some of his sexcapades even though they often had their own. First and foremost, they were friends and he would never knowingly hurt Sev. But sometimes he was just a stupid guy so he didn't give it a second thought before spilling out his story.
His arm moved to slide around her shoulders as she cuddled against him. Though he might never admit it, cuddling with Sev was one of his favorite things to do. He just liked how it felt to have her warm little body pressed against his. It was familiar and comfortable and something he sometimes took for granted. If Sev was around, he automatically assumed he'd be allowed to hold her. If the day ever came when he was not, he'd be surprised and not in a good way.
At her words and her snicker, he glanced down at her with his own amused smile. "I showered!" he declared, dipping his head to nuzzle her neck. "I promise I don't have a disease, it was just her hand." And damn had it felt good.
