Thomas barely stopped himself from asking if what he was doing was okay. He knew he needed to break himself of that habit, to trust his instincts and trust Krem to tell him something he was doing wasn't wanted. So, he kept his mouth fastened on Krem's neck, pressing open mouthed kisses down to his shoulder and back up again.

For a second, he kept his finger still, letting Krem adjust, letting himself get used to the feeling, the tightness. He gave his finger a slight wriggle, back and forth before slowly withdrawing his finger so he could slide it back in, faster and a little firmer, less tentative.
