Any pairing will do really, but I picture Molly/Fjord being easiest. His tusks starting to grow back in may present some, well, challenges using his mouth ;) I'm new to the kinkmeme, links to any similar fics are loved.

Here's something to inspire, maybe:

"Wait wait, love," Molly purrs, catching Fjord's jaw in his hand. Fjord looks up from between Molly's legs, eyebrows furrowing in confusion. His thumb runs gently over Fjord's lips before sneaking between them and teasing over one of his tusks; Fjord flushes a deeper green. "We may have to find something new to do with your mouth, now won't we?"
