I seem to have seen a request for Art and PWP prompts...
1) art: Severus might be older, but sweet Circe is he flexible!
2) art or fic: Young Auror Potter stops at an inn and finds his sleep filled with erotic dream visions of sex with Severus Snape. Meanwhile the mysterious stranger in the next room dreams of sex with Potter. (Fic could continue with the two awaking and stumbling into the hallway and having wild PWP sex.)
3) art: Severus and Harry tipsy together in a neighborhood muggle bar. (Does Severus giggle or smile or just almost smile when he's tipsy? Are they just tipsy enough to be relaxed, or is their balance starting to go?)
