seeking_spike | Buffy, William, and Spike fan fiction

Hi all! I'm looking for a fic that is Buffy, William, and Spike fic and in it Buffy is watching Spike and William (who are obviously twins) while their parents are put of town and Buffy and Spike eventually go at it in the kitchen is the first time I think and William sees and he gets mad and jealous and then Buffy and William and Spike are all together and when Spike and William's parents come home Buffy leaves and Spike and William haven't talked to her in a long time so they pull a stunt that they know will get her attention. They put A LOT of money into her bank account for her some sort of studio.

That's all I remember. Please and thank you!!!
