   Summary

   From the time he was in preschool, Izuku was always a sickly child.
   Tummy aches turned to a pit in his stomach he could never fill, the occasional sick day to constant hospital stays. They'd seen specialist and specialist, and still, no one could figure out what was wrong with the boy, and nothing could make him feel better.
   That is, nothing except for Katsuki.

   Or, Izuku has a sex quirk that no one knows about, including himself. He knows that hugging Kacchan makes him feel better, but what if doing other stuff could help even more? Katsuki is happy to help him find out.
