The corner of Remus' mouth twitched, knowing how safety precautions were regarded by the eldest Black. They weren't dangerous and cool, but Remus didn't want either of their heads to smash open because he felt like taking a ride, so he happily put on his helmet.
"Oh, I don--" Remus was about to contradict him but as soon as the bike gained speed, he lurched forward. Sure, he liked some fearful things, but that didn't mean he wasn't afraid. Involuntarily, he wrapped his arms around Sirius to hold on tight and almost all was forgotten. The sudden rush had his chest moving against the other boy's back until he'd calmed down and after a few seconds he started looking around, slowly getting more comfortable with the whole ordeal.
