As someone who had to call a biohazard team to clean bodily fluids, this is a nightmare. You gotta shutdown and cordon off the area and if it happens at night, they won't show up til noon the next day. And you have to give a reason explaining why no one is allowed in.
Subject perhaps to their own fetishes and preferences, the common conclusion that might have been reached by Aya's friends by the close just might be (thank you, TV Tropes): "Let Us Never Speak Of This, Again."
But then again, as long as Aya and Taku communicate well enough to accept each other's *koff-koff* "quirks" it's all right with me.
