Mato's fingers sink in for a moment before being repulsed by the sheer fullness after a couple millimeters, the swollen orb grumbling slightly at her as she disturbs its contents. The tawny-haired girl bites her lip as she feels her friend start to dig in gently, squeezing the stuffed flesh and moving about in circles. Her skin is very warm to the touch, slightly flush from how full it is, and with every few rotations, Strength lets out a low burp, the pressure in her belly starting to ease. The black-haired schoolgirl puts her other palm to the side of the stuffed stomach, starting to knead it from the other side once she realizes it won't pop or become more upset with just a little more stimulation. It was a strange sensation; she had never done this before, and yet here Mato was, massaging the stuffed gut of her best friend in an attempt to calm down one heck of a bellyache! It was slightly comical and she held back a short little laugh, knowing that her friend was in a bit more trouble than she was letting on.
"How does this feel, Yuu? Much better?" Mato asks, looking up to her friend's face. It was certainly working at the very least; Strength's cheeks were no longer flush with the effort of keeping her roiling belly from hurting, and a small smile was starting to curl on her lips from Mato's relieving rubs. Opening her eyes, she looks down, blushing a little.
"M-much better actually...ooh...it's so heavy though, I didn't realize I could get this full from the first time..." She moans, reclining against the seat a bit more. It felt even better than before, allowing the swollen orb to jut out to its full apex, the flesh growling softly in satisfaction at Mato's attention. Rather pleased with herself, the black-haired girl starts massaging just a bit deeper, squeezing the flesh a bit more than before, and really starting to sink her hands into it more than before. That's when it started becoming more than just a soothing belly rub.
The warmth of Strength's flesh tickles her deft fingers as she massages the taut skin, the orb now giving in quite a bit more than before and allowing her digits to fully grasp its size. Pale hands sink into creamy flesh, her palms working circles around the relatively taut surface, the softness of it causing Mato to blink and grab at it just a bit more. The stuffed belly was so soft, so cushy! Almost like grabbing a giant marshmallow...perhaps a memory foam pillow, just sinking her hands into it and squeezing as much of it as she could in one go. The warmth made it even better; so very toasty, and the way it wobbled lazily from her touch just made her want to shake it even more. Leaning against it, she could even hear the noisy workings of Strength's belly as it tries to digest the massive meal the poor girl had earlier, the sounds curiously enticing to her ear and tickling her mind a bit with the sensation. Giggling for a moment, Mato kept rubbing at the swollen gut, tracing circles around Strength's deeper navel with her fingers, even fondling it just a bit as her face flushed a dark crimson, her tongue poking between her lips as she slowly delves deeper into the sensation.
Not that Strength minded either. The roving hands of her friend felt so good on her sore stomach, the quick, relaxing strokes causing her to let out soft whimpers and moans of happiness as the pressure was eased off of her, her belly quieting itself as it was soothed by Mato's soft, silky palms. It felt so good, she could hardly stand it! Even her toes clench inside of her shoes as she brings up her legs slowly, enjoying the feeling of her flesh being played with and rubbed in such a way that was so unexpectedly delightful, none of this ever having happened before at other schools.
Alas, it wasn't going to last much longer...
