I'd like to recommend this story:
Title: Between Hope and Remembrance
Authors: scribbulus_ink (McKay) and arionrhod
Summary: After the war, Remus and Severus - two
unlikely survivors - must rebuild their lives against
overwhelming odds with the Ministry and Severus' own
memory throwing obstacles in their way. Oh, and
there's the little matter of Sirius' ghost...
Rated: R
Pairing: Remus/Severus, Remus/Tonks
Warnings: first time, frottage
In this story, Snape is given to the Dementors before his innocence is proven after the war ends. However, the Ministry is using a new type of Dementor that only eats memories, not souls. When Snape is freed, he has to start over without his memories, and it's very interesting to see what he's like without all the bitterness and baggage of the past weighing him down.
A Snupin fic, of course (do I ever read anything else? ^_^), and it does have a couple of sex scenes, which I thought were tastefully done, but mainly it's about Snape trying to start over again with Lupin's help.
