I get so irritated watching Buffy just forgive the gang (mainly Willow) every time they abuse magic. I would love to read any fics where they pay the consequences and/or Buffy doesn't turn a blind eye... Thanks so much

If you will PM me your email address I can send you Kari Mouke's A Not So Gorgeous Mistake. Willow and Giles definitely pay the consequences of their actions in this fic.

the pathway to hell, by me... Jamies_lady

Nimah's Originsverse series - particularly "Origins: Revelations" has Willow paying in spades. It's brilliant.

TalesofSpike's series that begins with Spike's Will Be Done has Willow paying very much for her magic abuse and this series is one of the best reads in the fandom. You can find these books at the bloodshedverse.

With All My Heart by Spikeslovebite is another fic where they suffer for their abuse of magic on Buffy and Spike.
