"N-Nozomi! You better let me out of here right now or I'll--gah!" Nico tripped as she got up, the "floor" underneath was slimy and unstable. Nico fell to the bottom of Nozomi's mouth with a sickly splash, and the giant tongue above her swooped down to pat Nico on the head playfully.

"Ugh! G-get off me!! Please stop Nozomi! It's hot in here and I'm tired!" Nico complained while she was getting a saliva bath from her friend's monstrous tongue. Nico's demands became more like pleas, and then suggestions as she began to slowly enjoy the feeling of being felt up by the giant pink tentacle. To Nozomi on the outside, it simply felt like she was playing with a piece of candy. She wasn't intending for Nico to like this little act of cruel playfulness, it was mainly for her own amusement, but she didn't mind if Nico enjoyed it either. In fact, if it would get Nico to shut up and stop complaining for once, Nozomi would happily go further with the girl, and so she did.

Right now, Nozomi was changing into her workout clothes to start idol practice. She'd mess with Nico for a bit and see how she if she still had any fight left in her afterwords.

In the clubroom changing as well was Hanayo, who struck up a conversation with Nozomi. Nozomi took this as an opportunity to mess with Nico further. Flipping the tiny girl onto the tip of her tongue, she would constantly give her glimpses of the outside world as she talked. Nico could see Hanayo's face from the inside of Nozomi's mouth, but Nozomi did a good job of making sure she couldn't be noticed by Hanayo, flicking her tongue back and rolling Nico around the bumpy appendage.

--

From inside Nozomi's mouth, Nico was wracked with the overwhelmingly loud and booming voice of her captress. Nozomi's mature, womanly voice echoed all around her, infinitely bouncing off the walls of Nico's moist prison and causing stay droplets of spit to fly and splash in Nico's face. It was safe to say that at this point her school uniform was completely soiled. Even Hanayo's cute, mousey voice sounded scarily imposing at her size.

Attempting to use her tastebuds as footholds, Nico tried to get Hanayo to notice hear by shouting and waving her arms. The light from the world outside this high school giantess' mouth was blinding, and Nozomi's mouth and tongue movements were too quick and erratic for Nico to properly see for more than a second.

Hanayo had finished changing and left the room, which left only Nozomi and her shrunken toy inside. The violent tongue movements slowed down, and Nico was finally able to get a foothold and sit down on the pulsating beast. It almost felt like Nico had been riding a gigantic mechanical bull. She was flipped and launched all around by it, but Nico kept hanging on by a tastebud. And now she had tamed the slimy monster.

Nozomi noticed this change and decided to let Nico rest for a bit. Nico sat in her lonely, dark cave. Saliva dripped from the ceiling and leaked from the floor. It was hot and humid, and Nico was covered in the slimy drool. Her clothes were soiled, and she was exhausted. Nico was almost ready to collapse, but the tongue underneath her reflexively made a pulsing movement whenever Nico put her hands on it. It vibrated through her entire body and sent shivers up her spine. Nico's panties had been soaked, which left her crotch rather open for being affected. Since she was sitting on the tongue, her privates were affected by this pulsating sensation. Soon enough, Nico was almost relaxed by this bodily function, and was, dare she admit, enjoying it!

"N-Nozomi, that's enough... you're getting me... hnn..." Nico moaned. She actually hoped Nozomi hadn't heard that. The flat chested idol would never live down being turned on in such a weird way.

And yet...


Nozomi sat in a chair in the idol clubroom. She had finished changing, but didn't really want to go to practice yet. She was having too much fun with her toy. She started looking at her phone while doing small, sensual movements with her tongue. Nico had only shrunken slightly while in her mouth, which wasn't what she expected.

"Maybe she finally learned to control her anger in there," she wondered.

Inside the teenage girl's mouth, on the receiving end of a tongue massage, Nico was feeling unabashed bliss. The movements and vibrations from the massive tentacle rubbing against her crotch, combined with the hot and humid atmosphere filled with the pheromonal breath of her friend, combined with the saliva lubricant that coated her and everything around her, made Nico extremely turned on.

"Nn... this... no... stop... no... keep going... hnnng!" Nico's tiny squeaks echoed through the dark cave. Nozomi began humming a soft melody to herself while she scrolled social media. This humming, while extremely loud, made Nico feel further excitement. Her entire world was currently the inside of her rival... that was... kind of hot.


Nico hated these conflicting feelings, and yet that was somehow what made it even more erotic to her...


The shrunken school idol continued grinding herself against the bumpy pink tentacle beneath her. She wished it would caress her, twist around her, squeeze her and cover her further in Nozomi's sticky saliva. All she could smell right now was Nozomi, all she could feel was part of Nozomi.

Nico was close to climax, just another minute or so, the pulsing vibrations from Nozomi's tongue continued, her sensual humming was consuming all of Nico's thoughts. Getting off was all she was thinking about, fully experiencing this strange bliss.


"Ptoo!"


The next thing Nico knew, she was shot out of Nozomi's mouth like a cannonball out of a cannon. Covered in droll, she was like a crude spitball, and she was hurtling towards the soft palm of Nozomi's right hand.

Nico landed with a crash, the immense layers of spit that covered her softened the fall. She was laying in the palm of the girl she was just masturbating inside of. Nozomi looked down at her with curiosity.

"So, how was it? Did you enjoy yourself? You seemed pretty calm near the end there," said the giantess.

"Uh- I- Erm, y-yeah, it was alright I guess..." Nico looked away, clearly blushing. Realizing she still had her hand close to her crotch, she quickly retracted it to her side and sat up.

"? What were you doing?" Nozomi questioned why Nico was acting so strangely.

"I-I wasn't doing anything okay! It was just... hot, and I was tired..." Nico's words trailed off.

"You look flustered. Care to explain?" Nozomi called her shrinkee's bluff.

"It was nothing! Now leave me alone! I just want to grow back..." Nico realized the way she was sitting clearly exposed her soiled white panties, so she haphazardly pulled her drenched skirt down a bit and fixed her posture. Luckily, Nozomi wouldn't have been able to tell if her panties were soaked from anything but her own fluids.

"Hmm~ I see~" the purple-haired goddess mused. "Well, if you won't tell me, it looks like I'll have to punish you again~ How's a cool dip in the girl's toilet sound?"

Nico shot up and stared Nozomi dead in the eyes.

"Y-you wouldn't!!"

"Oh I would. Now tell me, what are you hiding?"

Nico's gaze fell and her intense blush returned. She stared at her fidgeting thighs and felt that tingling sensation return to her crotch. Why was she getting turned on from this interrogation? Did this shrinking do something to her brain chemistry?

"It's just... the feeling of your tongue... against me... ya know... it was kinda exciting me... A-and I know it sounds weird, but you were basically molesting me you stupid cow! I was innocent! I started maybe slightly only partially enjoying the feeling of being rubbed against like that..." Once again her words trailed off, and Nico's face was now red as a tomato.

For a moment Nozomi had a look of surprise. Was Nico really admitting to being turned on by being in her mouth? The girl had to stifle a giggle, she knew Nico would be a good plaything, but not this good!

"My little Nicocchi..." Nozomi said in a motherly tone. "Was that so hard? Coming clean about your feelings is always good~ Now I just wonder, what should I do from here?" she openly pondered.


Indeed, Nozomi wasn't sure how to handle such a confession. What does she decide?
