@lygarx It wasn't just "Shirou's naughty dream" even if it was a "dream." Due to the spiritual link between Masters and Servants, Masters normally dream about their Servants' pasts while they sleep.
@McRawr Actually, according to canon, she was given a magic penis by Merlin and banged her sister while under her sister's enchantment, which produced Mordred. So, not only did she obviously have sex while king, we know of a specific instance of it happening. And yes, I am being completely serious. That is actually canon. Canon which just might contain a hotter combination of fetishes than most of these fan-made doujins.
