Remus felt...quiet, which was odd to say when they were both making a decent amount of noise. Sirius was louder, not just because they echoed inside his skull. His mind wasn't properly functioning, but Sirius noticed when Moony moaned, what exactly it was that made him cry out for more. Kinky sod, Sirius noted as he continued, not concerned about truly hurting Remus.
Instead, he smirked a little as his fingers moved faster from scar to scar, finding another one that started as soon as the old one stopped. That was based mostly on feel, as his eyes didn't have a good line of sight. Pads continued to kiss Remus, even with the distractions. But oh, their hips pushed against each other, and Sirius bit is own lip, not able to help the way his hips pressed against Remus's, rubbing themselves against him through the jeans.
