I honestly thought I’d recced this years ago – the perfect vid for a perfect couple, this hits on all the points that make their relationship so beautiful. Music: Letters From the Sky, by Civil Twilight.

Queen Upon the Ivy, by incandescent (lmeden)
They trip and fall by the lamppost, yet Susan doesn’t realize where they are until Peter looks up and gapes.
Adult, incest. A King and a Queen frolicking in the woods. Sexy times ensue.
Cause Effect, by idharao
She feels like her feet can eat up the floor, and that she can defy gravity when he dances with her. Distance is nothing, height is nothing. She can jump to the moon.
G, RPF. A beautiful glimpse of Ginger dancing. Not technically shippy, but the underlying emotions are definitely there.
Time Flies You Can’t, by Sabine
This girl body does what she asks it to, when she asks it, but sometimes when she doesn’t ask nicely enough she finds it does what it pleases. She’s been teaching it when to kiss and when to kill, though it wants to do both those things all the time.
Amazing post-series River POV. Shades of River/Simon, Simon/Kaylee, Mal/Inara – and Mal/River, which is the first fic that made this pairing work for me. Intense, dark-ish and slightly twisted (because River, oh).
Unrestrained, by Ardath Rekha
He had his arms around her waist a moment later. “Maybe we can do something to speed up the time,” he suggested in a low, enticing voice.
Adult. Slight canon divergence to fit in some sexy times. Because ooh lala, during their talk on the skiff you could cut the sexual tension with a knife! 
Vid: Give me touch, by AnneSoshi
Haunting vid, mostly X1. The song is seriously perfect for Rogue. Music: Touch, by Daughter.

Vid: Untouched, by Elsa
This manages to perfectly capture the tension between Margaret and John. Especially love the rather unexpected song choice – period vids tend towards the soft or dramatic. (The vidder also has a couple other N&S vids set to similarly unconventional music.) Music by The Veronicas.
