looking for fic series

["bighotvirgo" <bnorthcut@xxxxxxxxxxx>]

I need some assistance from your collective memories-mine seems to be 
faulty - 

I am trying to find a wonderfully steamy B/W series set in Season 3-I thought it 
was titled "On Occasion" and I thought it was by Kirayoshi but I'm not having 
any luck searching with those terms. 

Each chapter in the series is a specific encounter between B/W, titles are "In 
the Limo", "In the Locker Room", "in the Bedroom", and if I recall there's also 
one in a gazebo, and on the couch (with Buffy's mom in the room!), and in the 
kitchen. As I said, steamy, but also great characterization and overall sweet/
tender vibe. 

Perhaps the reason I don't remember specific titles is that oxygen and blood 
that usually supplies my brain went "elsewhere" when I was reading this 
series....

Any help is appreciated.
Thanks
