Shina remembers clearly how it began; it was an exceptional day, even though she initially didn't know it yet. It started like any other day for her: waking up, taking a bath and dressing up for school, going there and attending class, that boring yet mandatory things a high schooler like herself was expected to accomplish. 

 

It was when she finished the last of her class while walking across the corridor to the exit that by either fate or coincidence, she glanced her eyes just right to notice...something very small lying on the floor. She approached, for it didn't look like an insect; perhaps a very small doll. Yet, when she finally got close enough, she gasped surprised, before immediately silencing herself and looking around, checking if any other girl had heard her. Alas, that was fortunately not the case, so she was free to sigh a bit, before reaching out to her prize. 

 

She grabbed the tiny body, allowing her to confirm beyond a shadow of a doubt that she had indeed, found a tiny. It had no collar nor mark, so that meant this was a wild one, without an owner...until now. 

Shina knew that she would take care of this tiny, the poor thing must have a terrible and harsh life out there after all! Yes, she would take care of this tiny every need and whim, and thus it would become her property, her...pet. 

 

As she wondered how she would carry it safely so it didn't fall off and thus lose it while walking, a bright idea sparked in her head, and while blushing slightly, her mind full of lewd thoughts, she surrounded firmly the tiny within her fist, while she walked to the nearest bathroom...

 

 

That first interaction was one you would also remember forever since it taught you so much about how to handle yourself in your new, small condition. You remember it went like this:

You woke up, surrounded by flesh walls, a bizarre situation that made you for a second question the veracity of the situation, uncertain as to if you were still dreaming.

That was until you heard a voice. 

 

Looking back, you can reason why it was so impactful, for when you heard the loud yet clear voice, it hit you like being showered by the contents of a bucket of freezing water: in an instant, it told your mind this was no longer a dream! This...this was real!

 

The voice, female, and petite-in-nature (a fitting match to its owner, who you would soon meet) spoke, exclaiming excitedly: 

"Oh?! He started moving! And frantically too!"

 

She moaned for a bit, feeling how you moved as you tried to get your bearings in your new environment. Then, she continued speaking, saying: 

"Hello in there! I bet you would like to know where you are, right?" 

 

"My name is Shina! I'm a high school student and I guess you haven't seen my face yet, so I'll tell you: I'm a very cute woman if I say so myself!" the voice began to explain while introducing herself. 

 

In your position couldn't see anyone else, yet the constant reservations each word provoked in your current location made you shiver your spine, as the implications as to what exactly it happened were becoming harder and harder to deny.

 

The girl didn't feel that instead continuing her explanation by saying:

"I found you lying unconscious on the floor at school and I just had to pick you up..."

 

Knowing that what likely followed was the key information you required to understand where you were, you listened attentively, focusing your entire mind on it as the girl kept going, and saying:

"After that, I figured I'd make you my pet! I trust you're aware of the fact that you tinies have no human rights, you know, considering you're not human..."

 

For a brief second, you were left stunned: you couldn't believe her! Pet? Tiny? Not human? What...was she insane? Of course you were human! Couldn’t she see it? 

Your mind wandered, more nervous and stressed than before.

 

Again, the girl didn't notice your reaction, as she approached the conclusion of her explanation, saying:

"And you're such a convenient size..."

 

"...that I decided to put you inside of my breast!" she says excitedly and happily after a brief dramatic pause; you can easily picture her smiling broadly while cheerfully closing her eyes.

 

"Well then, how about you start your new life as my pet with a little game of 'pleasuring your master'?" the girl concludes, in an expectant tone; you can feel that every word she's uttered has led to this, and she wants for you, her "pet" to please her from inside her breast...

 

You again are left stunned and panicked, and now full of shock: your mind races, attempting to devise anything capable of explaining the situation OTHER than how this girl, this "Shina" described it.

It takes a couple of seconds before you calm down, and accept the hard truth: that she was speaking the truth. Everything checked out: the flesh walls, the moaning, the warmth...somehow, someway, you had been reduced in size drastically, small enough to fit inside a girl's breast with relative ease, with the first girl finding you doing exactly just that.

 

This time, your pause was noticed by your "owner", who in a slightly annoyed voice, said: 

"Hmm? What's the matter little pet? Are you nervous?"

 

Her tone then changes to a more inquisitive one, as she continues, saying: 

"Come to think of it, you've probably never been in a girl's breast before, have you?"

 

"Hehe, don't worry. I guess I'll just have to train you," she concludes again in a happy tone, likely rationalizing why you were pleasuring already. 

 

You might have lost your size, but you had not lost your pride. Pleasuring a girl that had in essence kidnapped you? Fat chance!

You put your mind to work, and quickly enough decide to struggle towards the light: it's likely from where the exit is. It's tough, as the flesh around you shifts and quakes, as the flesh tunnel attempts to mold itself to your moving shape; yet you push on. 

 

The girl wasn't expecting such a course of action from you, protesting in a surprised tone:
"Hey! Where are you going?"

If she hoped that with that she would be able to rein you in, she was sorely mistaken: you keep struggling onwards until you pushed at the very end of the tunnel. 

 

You become temporarily blinded by a comparatively overwhelming amount of light, for the inside of the breast is overall very dark. Yet you quickly adjusted yourself, and looked around; the sight was both wondrous and terrifying in equal measure. 

 

For you were indeed poking out of a mountain of round, soft flesh that it was a breast, hanging out from what you could compare to a large building in height. Yet this "building" was a living person, a cute girl with short silver hair and beautiful sapphire eyes.

She was also not happy with your actions, as she frowned her eyebrow over her one clear eye (the other was mostly covered by her hair), while her lips were curled down. The tone of her voice matched her facial expression, as she spoke annoyed:

"That wasn't an attempt to escape, was it?"

You gulped, as your mind raced for a way to calm down the colossus. Thankfully, she changed her expression to a more amenable one, as she asked:

 "Or... were you just trying to pleasure my nipples?"

 

She doesn't give you time to answer, as you feel how her nipple increases the pressure around your body drastically in a pulling motion, sucking you back inside her while she spoke again in an excited tone, saying: 

"I love your enthusiasm! But you're going to have to start by pleasuring my insides."

 

As you found yourself back inside her, Shina speaking, saying: 

"Come on now, show me what you've got little pet!"

 

Now fully aware of the terrible situation you found yourself in, you decided that your best course of action for now was to obey...even if it was a humiliating and unfair act from your perspective. 

Your actions soon achieved results, your licking and massaging making Shina moan loudly while she exclaimed:

"Yes, just like that! That's a good little pet!"

 

For some reason, hearing both the loud moaning as well as the high praise made you feel a degree of pride: you had managed to make a colossal giantess feel wonderful and on the first try no less! 

So, slightly invigorated and now fully committed, you return to work after a very tiny pause to prepare yourself to work: that previous effort might not have been overall very costly in terms of stamina, yet it had an impact regardless.  Yet in your second attempt, you again managed to make her feel good; not as much while at the same being more extenuating, yet still good enough to your "owner". 

She may not have felt as excellent as before, yet Shina still praised your efforts, by saying:

"That feels good! Keep it up!"

 

Feeling now more confident, you again took a brief second to devise how to make the best use of your hands, body, and tongue to achieve the desired result: you again massaged and licked her insides...yet this time, you were proven wanting.

You don't know how, yet this third attempt was a failure, and one that Shina, in an annoyed tone was ready to protest, saying:

"That was mediocre at best... Here's your punishment!"

The girl then followed up, increasing the pressure around you for a split second, before relenting. It had an impact and combined with how much more energy you spent in this new attempt, you were left far more expended than before.

 

Your mind panicked, fearing the giantess anger if you failed in such a manner again. So, you rushed your actions, trying to squirm and struggle while massaging just right to make Shina happy.

It was this hastiness that provoked an even worse result, as Shina protested by saying in a harder tone:

"You're not taking this seriously! Make me feel good or get back inside!" 

Not only did she squeeze you harder than before, but now she even pulled deeper inside. This act seriously drained your limited reserves of energy: if you messed up in such a manner a few more times, you're certain to be left with no stamina at all.

 

However, not all was doom and glum, for Shina noticed that her actions might have been a bit too harsh on you, as she commented once you found yourself in your new spot:

"Geez, if you keep on doing that badly, I'm going to end up pulling you back fully inside me."

 

You could picture her face shifting to become brighter, potentially smiling calmly again. At least, that's the picture your mind develops based on the tone of her voice, as she proposed:

"Hey, I have an idea. Why don't you wiggle a little further out?"

 

Both due to the fact of not wanting to annoy her even further, as well as curiosity as to why she was telling you to wriggle out, you comply with her command and begin to struggle forward again.

Her previous actions had left you rather deep, so you had to make multiple efforts to reach whatever spot she wanted you to be in. Yet Shina in a cheerful manner keeps encouraging each push, by saying:

"That's it! Just keep wriggling out!" when your efforts were greatly successful, and "Keep going..." when it took that bit harder to push forward.

As you got further and further out, you managed to once again find yourself poking out of her nipple. You for just a second wondered if this was where she wanted you, only for her to prove you incorrect by exclaiming:

"You're almost there!”

 

One final struggle you did, and a pretty successful one, since you spent the least possible amount of energy. You reach further out, with your full head, neck, and the top of your shoulders sticking out of the aroused "mountain top" you were on. Once you found yourself there, you saw how with a pleading voice and face Shina exclamation:

"That's it! Right there! Pleasure me there little pet!"

 

You followed her commands like an obedient puppy and licked and massaged in the area around you. The effects were beyond your expectations, for Shina the loudest moaned yet while congratulating your actions by saying:

"Ahn! A...Amazing! This is amazing! Don't stop!"

 

Even though you didn't want to disobey her, you remained steady for a second, dumbfounded as to what exactly had you done to provoke such a reaction. Yet Shina was too pleased to take notice of that, as she immediately explained:

 "Yeah! That's it! If you pleasure me in my G-spot, I'll enjoy it a lot!"

 

"Remember where it is little pet! It's not like it's ever going to change!" she quickly followed up while giggling a bit and closing her eyes; she must have found that notion entertaining in some manner.

 

That was a helpful lesson: you were not certain until now that G-spots were a real thing. You made a mental note to keep such knowledge in your head for potentially later...for you were not starting to feel the exhaustion pilling up, and thus didn't think you could wriggle or pleasure the giantess, at least for a while.

 

Shina noticed again you remaining still, and as she managed to see you gasping for fresh air, she figured out something was up, as she expressed:

"But... All that wiggling must've made you pretty tired."

 

With a calm face and tone, one she likely made to ease any potential tension between you, she spoke, saying:

"I understand if you want to take a rest, little pet."

 

You gladly followed such a command: you reduced your movements to the minimum while focusing on taking large, controlled breaths in and out, recovering a large modicum of the spent energy. It was still far from enough to recover fully, yet it was helpful and welcomed regardless.

 "Just take a little break, hehe." Shina comments, as she looks at you steading yourself in her nipple. 

 

Once she was certain you had finished resting, she spoke again, saying:

"There you go, you've got to make sure you don't run out of stamina, or you won't be able to pleasure me anymore! Now...keep pleasuring me!"

 

Her last words carry the tone and weight of command, yet you're not in the condition, not the mood to obey; you just keep resting more, trying to recover more energy still.

 

Shina doesn't like that, as she makes clear while exclaiming:

"Hey, I didn't say you could keep resting!"

While she does so, she pulls you again, fairly deep in one go. To achieve this, she pulled you with quite a strong pull of her inner muscles, making you cough out the air from your lungs; that act by itself spent a lot of the energy you had managed to recover.

To make matters worse, the hot, moist, sauna-like atmosphere of her insides finally gets to you, making you sluggish and drowsy as your remaining energies begin to siphon off you more and more while you remain inside her.

 

The slowness of your formerly vigorous movements and wriggling are easily noticed by how sensitive the girl is to your presence inside her. In a curious and surprised tone, she asks:

"Hmm? Are you really that tired?"

 

For a second, you thought she would get angry, as you can easily imagine her looking down in disappointment at your "weakness", incapable of keeping up with her lewd urges.

Yet the girl proves you wrong, for instead of chastising you for your failure, she instead calmly speaks in an empathetic tone, saying:

"I guess I can understand. It must be pretty tiring being stuck in such a hot environment for so long; you’ll probably get more and more drowsy the longer you stay in there.

 

"Come to think of it... even resting in there might make you drowsier. And if you run out of stamina, how are you supposed to pleasure me?" she concludes, after a brief pause in between her speech. 

 

A longer silence soon follows something you assumed is due to your "owner" taking her time to accept that her "pet" can only offer her so much. This is partly confirmed after she happily sighs, before speaking again, saying:

 "No, I understand. It's your first day there after all, little pet. Why don't you take a break for now? Starting tomorrow though, I'll expect you to give it your all!"

 

Right after that, you feel how the walls around you begin to shift again, pulling deeper and deeper, until you are inside a small space (likely a mammary gland of hers). There, exhausted and utterly spent, you follow her call for rest, taking a fetal position and closing your eyes. It takes but a few seconds before the sweet release of darkness claims you.
