Pull out Hera's old skirt and advance.

You pull out Hera's old skirt, calling out, "Vera, Sara?" and step out into their view. The two girls seem startled despite your careful approach and scamper to their feet. However after their shock subsides they notice that you are not threatening them and calm down, both of them looking a bit nervous and blushing slightly.

You walk forward slowly and hold out what proof you have of your love for goblin girls. One of them takes it from you, then looks to her sister and they start babbling their nonsense language excitedly. After a moment they advance on you with an eager glint in their eyes, their tiny hands starting to roam freely over your body.
