I'm pretty sure both stories were never competed. The first is Harry view's Snape's worst memory in a different way, he is able to tell the way Snape feels, which is his love towards Lily and accidently thinks Snape's in love with James. Snape realizes this and let's Harry think it's true feeling that he is somehow protecting his true feeling from Harry. (This part might accutally be from a different story, but I'm not sure) Ron and Hermione see Snape take Harry out into the forest and think something sexual is going on when really Snape take Harry to a clearing in the forest where he tells him he's able to apperate from if he needs it. Shortly after that Snape forces himself on Harry, although Harry doesn't like the sex he feels more like a man afterwards and tries to stop Snape from obliviating him. Snape lies and tells Harry after that he had a bad Voldemort vision moment Harry gets scared and decides to leave Hogwarts. Before he goes Harry finds sexual evidence and goes to confront Snape.
