Looking for kinky McShep stories

[mixed-reviews.livejournal.com]

But a -specific- kink! In Smallville, there were more than a few fics where rimming was new to one character, and I'm hoping to find something like that for SG:A.  Neither one has to be a virgin, just new to rimming, embarrassed, but all ends well of course. Does anyone know of fics that fit this, even loosely??? This fandom rocks when it comes to finding things near-miraculously, so I'm sure you lovely McShep shippers will dig up something

body swapping

It's a common enough SF trope and I was wondering if anyone knew of any SGA fics in which people end up in one another's bodies. Gen slash or het, I'm good with all of it.
