Transformation bunny for a slashwriter

[krande.livejournal.com]

I've been reading a sticky-fic recently and a bunny kept running around all the time: why do we force the TFs to behave like humans if they are TFs afterall? Previously I believed I'm not the only one dreaming about TRANSFORMING a real TF. Holding them in your hands, carefully turning, flipping, rotating their parts, etc. If you write it well, it could be very personal, intimate, and undeniably a fan(girl)s dream.
I'd love to read an otherwise slash-y story where "traditional" 18+ scenes would be replaced with one TF transforming another. Or you can include a human if you feel like, but please be rational with the size of the characters.
Whether you write it with femme or mech, it's up to you. But if you go into the details of transformation (I think you should) please use a real TF figure's transformation as a source. Some complicated toy lines (Alternator/Binaltech, Masterpiece, Leader size etc) would be preferable. Don't forget about the rubsign :)
And a request: please don't just take your favourite pairing and get them have some fun, I'd prefer an actual story. Or more stories.
