Lost Fic

I am looking for a story I am pretty sure is on ff.net. In the story Rossi had planned this romantic evening for a date who cancels. Since he prepaid he asks Reid to go with him non-romantically once he sees Reid is having cereal for dinner. The waiter gives Reid a flower meant for the date, they have oysters and Rossi fake proposes. The next day Reid is telling Morgan about the dinner but Morgan misunderstands and thinks Rossi and Reid had sex last night and Reid only did it because Rossi had payed for dinner. There is some line where Reid says Rossi was on his knees last night and one where he says something like "I should have just swallowed." I can't find this anywhere. It may have been part of a longer story or not.

Thanks
