I have no idea where I read this, but the fic is set in an AU where Jazz is the Prime (not Optimus), Prowl's his mate, it's the end of a long day, and Jazz/Prowl head for their chambers and then it's just one big mech-sex scene, lol.   That's the only story I've read, but I'd be interested in any authors who write/and stories set in that AU.  Thanks for the help!
