I shall inaugurate then! I hope lots of people participate because this is really fun!
Just so you know, this game was first given to me on a French site, where the word total was changed from 15 in English to 20 in French. I put if back to 15 for this, since that was apparently the original limit, but as a consequence a few of these fics are slightly over 15 words, since they were a tad longer in French and got even worse when translated. I hope you'll forgive me!

First Time 4&6

AU 1&8
Slytherin's red queen bumped into the Gryffindor boy. "Get out of my way, Zabini!"
Threesome 3, 6&9
Lavender looked from Bill to Sirius. She'd always liked her men a bit... canine.
Hurt/Comfort 5&10
Seeing her sobbing, Dean comforted little Ellie during the ceremony commemorating Muggles that died during the war.
Crackfic 1
When Harry dumped her, Ginny decided she had had enough of men and set her sights on the Bloody Baron.
Horror 10 (I had two ideas for this one and couldn't pick, so I wrote both)
Dean was forty-three years old when he finally learned how his father had died.
Dean screamed when, three seconds before the end of the final game, the opposing team tied the score.
Baby 5&9
After having cleaned him up, Lavender placed the newborn in the arms of Ellie, who was exhausted but thrilled to be a mommy.
Dark 2&8
Blaise thought he was alone when he cut into his forearms that night, but Peeves was floating at the window, invisible.
Death fic 2&3
