Lia

After a little more convincing, Lia finally leads the way into the dark hallway. As an added bonus, you cast a weak spell to create a light orb that goes in front of Lia, so she can see. It also allows you to see, to see her ass that is.

"Hey I think there's a room here!" She says loudly. Sure enough, there is a large room, with a strange pedestal on the far side of the wall. On the pedestal there is what looks to be some kind of golden artifact. You walk towards the artifact, strangely attracted by its odd shape. It seems to be a kind of medallion with a pair of nude breasts engraved upon it. There is a note attached to it, which reads "This is an artifact of the sex dungeon. One of many you will encounter while exploring. This here is the breast medallion, which can alter the size of any pair of breasts the user is thinking of if tossed into the wishing fountain."

You decide it would probably be best if you just pocket the artifact and maybe use it some other time. "Other artifacts though? Maybe the dungeon wants me to fuck Lia or something?" You think. Lia is on the other side of the room, and she is going through a bookshelf. It's full of erotica, and you pretend not to see her grabbing a lot of them. Suddenly the pillar that the breast medallion was laying on glows an acid green color and it spreads through the design on the floor. It looks like a map, linking everything with the acid glow. There are many dots on the floor, but only one is glowing white, the others stay dark. The white one is in the center of the map. "Ohhhh this must be a map of the dungeon!" Lia realizes, tracing the lines with her fingers, "And this is the center room where we were earlier." She is correct, that would make the most sense. "Do you think this pedestal thing warps us back or something?" I ask. "well, only one way to find out anyway. Lia come over here, let's try it."
