Final Fantasy VII, Genesis/anyone, his voice
As much as Angeal complained about Genesis' incessant tendency to quote poetry - and despite what everyone thought, it wasn't just Loveless that he quoted - he wouldn't give up the man's voice for anything. He loved hearing it, whether he was simply talking to him in an every day situation, or growling and screaming in battle, or moaning like a two-gil whore while split open on Angeal's cock. All of them were good noises, and really, the former two tended to lead to the latter anyway, one way or another. Whether Genesis tugged him into a supply closet for a "quickie" - and the janitors had quickly learned to stay away from moaning supply closets - or he pulled Genesis into the dubious privacy of a bush, the both of them covered in blood, gore and ash, they'd eventually end up fucking each other violently while their teeth clashed and their tongues made love to each other, and Genesis' voive rang out in husky groans and mumbles.
This was one of the slow times, though. One of the times where Angeal had spent time cooking up a rich dinner full of their favorites, and then they took turns feeding each other bites of apple pie and ice cream off of their bodies. Now Angeal's head fell back as Genesis took one last bit of ice cream and swallowed it down along with Angeal's cock, the contrasting sensation of the cold treat and the heat of Genesis' mouth startling his own voice from him. He didn't like it as much as Genesis' - it didn't have that effortlessly musical quality that could shape words as if they were magic - but Genesis seemed to love it, and that was good enough for him.
