    Summary

    This is exactly what it sounds like. Steve transfers part of the serum to Tony through sex. Not all of it, basically just enough to make Tony look and feel ten years younger. And also it shortens his refractory period. Also there’s med-kink. Maybe it’s worse than it sounds, I don’t know anymore haha…

    This is a spin-off of a chapter from the previous story in this series wherein Bruce finds out Tony and Steve are sleeping together due to an abnormality in Tony’s blood sample. The first chapter is nearly identical to that, but the rest is original content.

    See the Notes in chapter one for more detail on what "med-kink" entails.
