*gets a little nsfw by the end, includes public stuffing/bloating and burping*
"So uhhh... I think maybe we should leave"
"I... Well..... Feel" you said, guiding her hand to your belly. Sure enough she could feel it gurgling and bubbling beneath her palm, and now you'd pointed it out she noticed the fabric of your clothes dimpling and stretching slightly over the bulge of your stomach. "i think i over indulged a little at the buffet" you whisper, glancing around as she surreptitiously rubs the side of your stomach, hoping nobody is paying too much attention to the two of you.
"does it hurt?" she says, gently holding your sides.
"a little... But it's okay" you loser your voice "it feels really good actually, I'm just worried people will notice if... If it gets any bigger... *hicc* oof it's already a little swollen" you reply, your belly bouncing a little with the hiccup.
"don't worry, get some ginger ale to settle it and after the talk we can leave, but i can't just rush off from a work thing. " she smirked a little as she kissed you, running a hand down your belly and quickly cupping it's new curve before pulling away. "although you know I'd love to" she whispered winking.
You agree, grab a ginger ale from the bar and settle yourself on a sofa in the corner, happy to people watch while she networked. Lost in thought you don't notice the passing server's occasionally topping up your drink and you start to absentmindedly snack on bowls of nibbles. You only realise you're predicament when half an hour or so later you feel a deep gurgle in your gut... You hadn't even noticed that your free hand had drifted up to rub your belly as you were eating and was now resting atop quite an impressive stomach. Round and heavy, your clothes were now clearly stretching to accommodate it as it had expanded out into your lap. You groaned, realising the gurgle was a signal of what was to come as you felt your belly rumble before attempting to stifle a deep, satisfying belch. You blushed bright red, covering your mouth and praying you hadn't drawn any attention to yourself...
"babe how... How did you even manage to get this full so fast!?" she appears beside you on the sofa looking both concerned and impressed.
"I..." you opened your mouth to try and explain yourself but now that you'd burped once the gates were open and another burp slipped out, cutting you off.
"*UUuurP* oof... Sorry I... *BleuuUurp* got a little distracted, i didn't notice how much I was eating" you said sheepishly, struggling to get the words out between burps. Cradling your belly you groaned, leaning back into the sofa. You felt the ginger ale slosh inside you as you did so, and immediately regretted the decision to lay back as you felt the weight of your stomach pinning you down, and the tightness of your skin, stretching over your gluttony. "hey babe... I could really use a belly rub right now" you whisper, suppressing a moan just thinking about her soft hands sliding up and down your sides, knowing just the spot to massage to release the pressure in your gut. You looked at her with puppy eyes, knowing she couldn't resist you. Teasingly she gave you a quick, but deep kiss and patted your taught tummy, she took your hand to help you up, but even that gentle pat was enough to dislodge an air pocket and you couldn't help letting another long burp slip as you struggled to your feet, jostling your stomach. Now you were sure people were looking, your belly was so disproportionately huge compared to your regular frame and no matter how hard you tried to hold them in burps just kept slipping out. You were quite a sight.
"There's a private bathroom down the hall, all you have to do is make it there and then i can rub that belly like it deserves" she whispers. Every step you feel your stomach bubbling and sloshing, your centre of gravity is disrupted and you practically waddle down the hall.
When you finally make it behind a locked door, she presses you hard against the wall, kissing you and pressing herself against your swollen middle. "you're such a tease" she mutters, running her hands over your belly, "you have no idea how much I've wanted this all night, watching your belly getting bigger and bigger and not being able to touch it and squeeze it, i could hardly take my eyes off you". While she speaks she begins massaging your gut, alternating gentle stroking and deeper pressure, forcing the gas out of you in deep rolling belches. Her hands feel heavenly on the tight skin of your belly and with the pressure of her body pressed against yours you can finally let yourself burp freely, feeling them vibrate in your belly as they rumble out of you.
