salemjadaHi,
I was just wondering if you're sure, because it does sound like 'Changes' by dreamweaver
This is fluff, a sequel to "Her Way", a romp through all the changes everybody has to go through once Buffy and Spike claim each other.

"Ah." The Firoud looked relieved. "Is it permitted to speak before them, Slayer?"
Buffy shot a glance at Spike, then nodded. "If it does not bother you to do so," she said formally.
The Firoud shook his head. "It is about the Shonai." He gave Spike a beseeching glance. "The Master knows."
"The Mas..." began Xander scornfully, then shut up when Giles elbowed him hard.
"Spike is the Master. For God's sake, will you be quiet, Xander! If you can't, then leave."
"The Shonai is their mating ground," Spike was explaining quietly to Buffy. "They need an area close to the energy of the Hellmouth, which also has a stream of living water running through it. Can't be just a rivulet from the sewers. Has to be a spring. As you might expect, that's hard to find."
