Maybe part of the fun here was also seeing how quiet they could be while not making it easy to be quiet.

Annie gave a sharp little gasp of pleasure -- it wasn't like she wasn't familiar with how it felt to get her hair stuck somewhere or something -- she'd had long hair for, like, twenty-odd years -- but having Diego's hand in her hair and layering that on top of slowly-building pressure and all this intimacy and sensation was...hot.

It had her upping her efforts slightly, trying to fill her movements with deliberate intent if she couldn't have speed or aggression on her side right now. It also had her trying to muffle some pathetic whimpering with kissing, because who could have predicted that being quiet would be more difficult as time went on, here? (Not Annie, certainly. There wasn't that much foresight to go around.)
