Her g-pot, both a place of fresh rest and her most sensitive spot on her nipple Tiny Misadventures, the Interactive text story chapter 8 by Calvitonks

You quickly decide that you need to reach the outside of her nipple: being outside of her innards would allow you to breathe fresh air, as well as put you in reach of her G-spot, which, if caressed enough, would surely provoke a new orgasm for the girl in far less time than licking her on other places. Yet this also means that you will find yourself partially outside her and at risk of a full exit, something Shina will surely make her very best to prevent.

Nonetheless, you didn’t let the prospect of a greater challenge than before deter you from trying, beginning to struggle forward to reach your destination.

“Hey! Where do you think you're going?” said Shina when she felt you moving: she was surprised that her pet, who has previously just massaged and licked her insides just minutes ago, started to move, but otherwise enjoyed the tiny’s actions as his movements not only made her feel good, but provided her with an excuse to pull him inside that she would otherwise had lacked.

And thus, a competition between you two began, each attempting to surpass the other on how deep you found yourself within the giantess booby, with many occasions finding yourself pushing forward a decent distance before her insides pulled you deeper. To combat this more effectively, you paced your movements with intermittent rest, not only allowing you to extend your stamina but also to prevent Shina from fully tensing her insides and thus making any kind of movement practically impossible.

“Heh, my tiny sure knows how to squirm. Doesn’t matter: I enjoy how you struggle, keep it up, you might succeed.” The giantess commented in a teasing tone, confident that your efforts would be in the end fruitless.

Her confidence was reduced only to be replaced by lust when you started to lick her in her most sensitive spot, making her exclaim:

“Wait, if you pleasure me there, I…I...I don’t care that you're slightly out, just don’t stop!”

You’re not one to disobey such a command, and soon your efforts give rise to another mighty surge of milk, one that, due to your current position, shoots you off her breast. 

What follows is a brief moment of sheer terror, for you find yourself in freefall from what to you is a height comparable to dropping from the top of a skyscraper, approaching at lightning speed the hard substrate at its base. Yet your current tiny size proves to be an enormous blessing this time, for your hit with the hard tiles on the bathroom floor leaves you without harm: you're not even dazed by the impact, an excellent detail to rely upon for potential future attempts. 

As you raise yourself and take the opportunity to stretch out fully without any constraints, you get to witness the gorgeous view of truly humongous breasts, nothing hiding their sensual beauty. Honestly, this is a perk in your overall bleak situation.

What do you decide to try now that you’re outside her body for the first time?
