I read Slaymesoftly's No Harm the other day and I wondered if anyone knew any other Something Blue fics where the spell breaks whilst Buffy and Spike are having sex. Same scenario for any other episode setting if one or both of them are under a spell that breaks during would also be great to hear about, like The Gentleman Wore Leather by slaymesoftly, More Than Candy by kari mouke and The Halloween Series by spike_spetslayer which are all Halloween fics.

But anyway, definitely Something Blue but others too, so long as a spell is on one or both of them that breaks during sex.

It's not Something Blue but in Nauti's At It Like Rabbits the spell that has turned Buffy and Spike into rabbits breaks in the middle of sex. It may not be Something Blue but it is Season 4, IIRC.

Ah, yeah, I forgot about the Bunnyverse. I agree it is S4.

Went through my Something Blue file and there's also Just a Little Spell by Slaymesoftly. for Something Blue interruptions. Seems to be Slayme's leitmotif.

There's also a number of "Where the Wild Things Are" fics. Most of those have a spell breaks in the middle of sex component. My file includes (I'll try to add links later):

Wild Things by Nauti
Uncontrollable Series by Sweetprincipale
Married? by apckrfan
Possession by Ameeya

Ah bless you, thanks for these and for trying to find more suggestions. I have read them all but I had totally forgotten about Just a Little Spell and haven't read that for a long time so I think I'll give that a reread next. I might have a trawl through Slayme's fic list just in case there are any I have missed of a similar vein.

Just reread "Stay" by Holetoledo on this site. Short, but sweet!

I haven't read many short fics so that is a new one for me, thanks

great suggestions - I've not read Married - hope it's here.

Married? is on fanfiction, It's a long time since I read that one but I remember it getting quite emotional, tissues at the ready!
