   Summary

   Regulus loves his boyfriend, James, more than he’s ever loved anyone. A frightening realisation, but one he’s comfortable admitting.

   Unfortunately, as much as he loves James, there is one pretty major issue in their relationship which his boyfriend remains blissfully unaware of.

   Due to his high protein diet, James Potter’s cum tastes like vinegar, and Regulus can’t keep pretending like it doesn’t bother him any longer.
