  Summary

  Simon understands the protective qualities of the thin mucus that seems to come from everywhere, but if he’s honest, when he realized that he could easily work up a mouth and throat full of gooey, body-warm slick, and didn’t have to worry about traditional human breathing…well. His mind jumped into a rather obvious gutter. One that he’s finally on his way to roll around in right now.

  Or: Ryland Grace enters the splash zone.

  Summary

  Entirely by accident, Grace sees Simon out in the water in his mer hybrid aquatic form, and, without thinking, raises a hand in greeting. Simon raises his hand in response before catching himself and ducking back under the waves. He feels guilty for intruding, but that evening, Simon tells him that he didn’t mind and Grace was welcome to come see him while he was in the water. If he wanted to.

  Of course Grace wants to.

  Or: The bio-dome ocean isn't all that interesting, and Simon gets some enrichment for his environment.

  Summary

  Simon is a quiet man. Especially – to Grace’s current frustrated fixation – when they’re…being intimate. He knows Simon gets off, he says he enjoys it, he certainly looks like he’s enjoying himself, and gosh is he pretty, with his curls damp from sweat and his face flushed and glowing. Looking up at Grace with his eyes so soft and hazy with pleasure, panting and – wait, that was the current problem, Grace couldn’t get more than breathy pants and choked gasps out of the man.

  Once – once – he got a breathy little mm! that absolutely haunts him.

  Or: Simon is so quiet in bed, and Grace is a little unhinged about it.
