Kink meme help?

I KNOW there was a prompt on the kinkmeme a while back about TFP Megatron giving Optimus a recording of exactly what they got up to when Optimus was on the Nemesis as Orion with no memory. I've written a fic inspired by it, but I cannot find the prompt. I've used the Delicious searcher/index thing and cannot find it. Anyone know where it might be?

Summary:

The Star Saber is broken, and Optimus and the Autobots face a bleak, uncertain future. But when Megatron and Optimus meet in battle, Megatron spares him. He offers Optimus a recording that reveals exactly what happened during the time he spent among the Decepticons, his memories of Megatron's evil erased. But is Megatron simply tempting him with memories of something that could never be, or does his "gift" serve some deeper purpose? 

Notes:

For Lyricality.

Inspired by but not quite filling a kink meme prompt I cannot find, about Megatron showing Optimus a recording of what he did as Orion Pax, Clueless Adorable 'Con.

Written for Lyricality for her birthday. Or rather for "I thought today was your birthday, dammit, sorry I'm late."
