Post-resurrection, Clark decides he wants to take a look at what Lex did to the Kryptonian scout ship, and Bruce is interested in getting hold of some alien tech. So they break in to whatever facility it got hauled off to.

Things go wrong and the ship's kinky tentacles start getting a bit violent and handsy. Supes is still weak or there's some fragments of Kryptonite around *handwaves* and the ship is technically under Lex's command so Clark can't call them off.

They both get held down and fucked by tentacles in front of each other is what I'm getting at here.
