Helena kept her sneaky grin up while you sweated nervously wondering what she was planning. Still hanging by a thread, or in this case, a string, all you could do was stare at Helena's face which was quite lovely from your point of view. Then out of nowhere, the mountain nymph opened her mouth wide and was bringing you closer!
You yelped in surprise and tried to stop her, "Whoa, whoa wait! Are you trying to eat me?!" Helena closed her mouth and spoke, "No, of course not, dear. This is the next part of our game. You're going to go spelunking!" You never heard of it and were confused, "Wait, what?"
Helena explained, "Spelunking is where you go exploring inside caves. It's a hobby of mine that I enjoy. It's really fun and I want you to try it."
You now got where this was going, "Ok. And this "cave" I'm exploring is actually inside you?" you asked nervously. Helena simply said, "Mm hmm"
You were unsure about this, "Are you sure about this? What if something happens? Like I end up getting stuck or something?"
Helena sighed at your worrying and had to calm you down, "There, there sweetie. This is why I tied the string around you. To make sure you get out safely. Also because of your size, I doubt you'll cause any irritation going down or up".
You were a bit calm but still had second thoughts...not that it mattered because Helena was still going through with this.
You gave in and said to her, "Ok. I'm ready". Helena smiled, "That's my good little snowflake. Trust me, you'll a have REAL good adventure in here". she said while patting her stomach. "Oh, but first..." she spoke again and tapped your forehead, causing sparkles all around you. You were about to ask but she quickly explained, "This little spell will help you see in the dark." You nodded your head in understanding. Helena wasted no time and opened her mouth again bringing you slowly onto her tongue. She then brought it back in and closed her mouth, sealing you in. Thanks to her little magic, you can in fact see. It was like night vision without glasses. You stood up and looked around the mouth. In your size, it was exactly like being in a cave, with a little air roaring around, the teeth acting like stalagmites and stalactites and drops of saliva, some dropping on you, much to your disgust, but you shook it off. You then balanced yourself on the tongue and walked towards Helena's throat. You then noticed something hanging: her uvula! You got an idea from those cartoons you watch and decided to try it yourself. With your biggest leap, you grabbed on to it and swung back and forth. It was pretty fun just like on TV.
Outside, Helena felt a tickle in her throat and thought it was you playing around. Thankfully, she was able to control her gag reflex. She called out to you, "And what do you think you're doing in there?" You answered back, "Oh, just having a little fun in here." in a sly tone. You hung on her dangling flesh and looked down to her throat. You saw her vocal cords and windpipe and were amazed. This was different than any usual spelunking.
And you were just getting started...
