Buffy isn't ready to deal with Spike's confession of love, but finds it hot when he says it in bed

I've recently been digging back into the archives for Spuffy fic, so I have no idea how new/old this one is.

I specifically remember at one point Buffy and Spike were in bed, and he told her he loved her - in a sexy way, not a hopeless romantic way. She had an unexpected reaction - eyes rolling back, finding it pleasurable. Spike's internal monologue was similar to: 'she might not be willing to accept it, but she's not opposed to hearing about it' - and then Spike proceeded to describe how he felt and what he was doing/going to do to her. It was very NC-17.

I hope this rings a bell? Thanks!
