Love Potion H/R fic

Hi Everyone, I am new to requesting fic , so I hope I am doing this right. The fic I am looking for is the "love potion fic" I swear it is called cupids arrow or love potion #9. A scientist creates a "have sex with the nearest warm body" potion and someone releases it in DC. In addition to the CM story it has chapters on the White Collar 'verse and I think Bones as well. H/R wind up bonded and I'm pretty sure Prentiss  gets pregnant by Morgan.( I hope I'm not making it sound like a badfic! It really isn't)
This started off as hmm I think I will re-read that story, but now that I can't find it, it has become my personal mission. Thanks in advance!
