buffy and spike have sex with willow in bed with them

I read this story on elysian fields. It is after both shows and something and spike and angel getting tortured and being able to switch places. Also in a car ride someone saw spike in the mirror. There is a part with spike going to train with the other slayers and one of them hits on him and he losses it. I forgot to mention this starts out with buffy living with some guy.

I just read the title and its spike n buffy having sex next to willow not a threesome
