[Darkladyknith`s story This war of Ours]

Does anyone know is this story reposting. Because I´m sure I have read this same story different name and penname. It have atleast two seqiels. I don´t want to accuse anyone plagiarism. All these stories were original male/male site.

[Looking LM/HP/DM fiction]

I´m looking slash fiction. It was threesome between Draco, Lucius and Harry. Harry was only sub. It was oneshot. Harry was leaving Auror training camp and they had funnight before separation. Story has snake shape dildo and double penetration. I remember readint it about 2-3 years ago. I read it AFF and it was on Harry/Draco section.

If you can help me, I´ll be very thankful.
