buffy and spike have a one night stand and buffy falls pregnant but spike doesnt remember anything

I read this fic a while back its AH fic where Buffy and spike are friends and share a apartment together with willow, xander, tara etc and one night spike drinks too much at a frat party after dru dumps him and Buffy trys to help him home or to bed and they end up sleeping together. Its buffys first time but spike doesn't remember anything so Buffy never mentions it but then she finds out she is pregnant but by then spike and dru are back together so she doesn't tell him the baby is his. I think its a couple of years later the truth comes out but its dru that points out the baby is his..... Any ideas?

I've read this one but I can't remember the title or the author and it's going to drive me crazy until I or someone else does! I seem to remember them being in the kitchen when Buffy realizes that Spike doesn't remember the night before. And isn't he the one that's the most concerned about her condition and wanting to know who the father is?

Thanks Nikkia! I think this is the one Spikes Slayer is looking for, I plan on spending my lunch break reading it again.
