No matter what Remus did or didn't have in him, it was definitely going to take awhile to find out. That, or Sirius would just have to push to get there because Remus wasn't one to actually take control (save for those odd times that were mostly behind him). So far there wasn't anything he'd thought of to be completely opposed to and he had no reason to stop Sirius, making it seem like smooth sailing.
He definitely didn't mind being touched. It wasn't so dirty, but it was comfortable and nice and when mixed with the lean...it never took much from Sirius. Remus thought he must be entirely too weak for such simple things to affect him so much. His breath caught and he leaned in even more in order to kiss Sirius properly.
