1 or 2 eggs appear (it's a bug that hasn't been fixed), you must collect the one in the middle of the wall to move the scene forward. If that one doesn't appear you can go back to the dungeon & return to force new eggs to spawn until it does; opening & closing the Book of Girls does the same.Hey no mod or so... just playing... I was feeding her, transforming her completly and make her pregnant, she is now not pregnant anymore and layed 2 eggs that stays in the book. When i go now in the cave there is no spot like befor for feeding her and the quest stucks at that point.
When the scene is over go tell Erevi about her. When that scene is done as well you can go back to the caverns again and feed her by giving it directly to her. TIP: do this before asking for sex. Her "Affection" is actually how well fed she is so give her large carcasses (one per day). The higher her "Affection" the more eggs she lays.
