Waaaay back in the day, I read a story that had a really hot interlude that involved Spike cornering Buffy either at the Bronze or another night-time venue. Pretty much all I remember is Buffy wearing tight leather pants that Spike had to peel down, and perhaps afterwards some swirly magical lights/portal appeared in the corridor. Geez, could I vague that up for you!?
It's the one adult scene that's always stuck in my memory... I just can't remember what the rest of the fic was about!
I think it was a longer-style fic, with a Kantayra/Sarah Aless type of vibe... |
