The talks between the two men inevitably got stopped by Xaya as she took her husband to the other end of the hiding place. She couldn't withstand being ignored like that and so, her husband's face got thrown into her ample bosom.
This was the usual action for Kyoya already, but he knew that a lot more hides beneath that action.
His wife just couldn't let him go and make other connections and relationships. The fact that only an hour passed yet Xaya went for rather too affectionate actions shows how clingy his wife is.
'If it was the death castle…'
Some people know Xaya here and so they don't hold any 'lustful' feelings for her! For them, she was the youngest and most naive disciple, so the disciples would probably talk normally during their breaks.
Maybe Wron, the black crow, would raise some perverted remarks, but against such a person, Xaya could only bare her fangs.
