Anyway, this has to be read for the title alone (who can resist a fic called Stark, A.E., and Banner, R. Bruce. (2013). "Biodosimetric Tools for Measuring Induced Isomeric Transition in Inverted Paired States." International Journal of Radiation Biology 89.9, 43-85?). It's very heavy on the Tony/Bruce (which is as it should be) and Tony/Hulk (which is okay), and I would recommend not reading if you don't like the idea of hot man/man sex. Or indeed hot man/enormous green rage-monster sex.
Sarah - are you paying attention?
