Thank you all for your lovely suggestions.
agooism won with the idea that Harry could be a shop owner. As your prize, Tara, here is the Draco/Teddy drabble you requested. You didn't specify a rating, so I went with my default hard R/NC17 :D
Red Days
Draco smiled a wicked smile. It was red today, deep crimson red. Draco licked his lips. Red days were his favorite. Red days meant French maid costumes and hard spankings and blindfolds and long, involved role-play games that ended in hard fuckings against harder furnishings.
“Are you going to stand in the doorway all afternoon or what?” Teddy asked, lounging naked on the bed. Draco’s eyes narrowed. His insolent tone was going to earn him a very hard spanking indeed. From the look on his face, Draco thought that might be what Teddy had had in mind the whole time.
On a side note, I'm thinking of doing a drabble a day project for the month of April. I'm going to assemble a list of one-word prompts to use for them. Any suggestions would be much appreciated.
