LF: old skool SG-1 threesome?

[mremre.livejournal.com]

I could have sworn it was an astolat story, but it isn't on intimations.org--which I confirmed by rereading everything on the page ;)--so I must have been hallucinating it.

What I recall is that SG-1 was on a geologically active planet and they came back covered in mud etc. Daniel turns out to be hosting a mineral lifeform that is growing in him. He spends lots of time sexing it up with Jack and Teal'c because the lifeform jumpstarts the host's libido to give it pleasure before it dies. Daniel teaches the lifeform English, and they end up having more hot threesome fun while the lifeform manages to cut itself out of Daniel without killing him. They leave a curlicue tattoo-like shape on Daniel's hip as a souvenir. Help?
