Work Text:
Teasing hands and playful giggling wakes me up from my slumber. I need a few moments to fully wake up, but even through the fog of remains of sleep, I can feel my girlfriend's hands sliding under my pyjama top. Her fingers flick my nipples playfully, and my eyes open all the way. A soft moan leaves my lips as my body lights up under her sensual touches.
“What are you doing?” I mumble. She grins at me and pinches my nipples. My body arches off the bed in pleasure, and my hands grip onto her shoulders on instinct. Her lips graze my neck, her hot breath tickling my skin.
“I wanna give you a kiss,” she whispers to me hotly, “you know what kind.”
That makes me sit up to face her, fully alert. Oh, fuck. I know exactly what kind. My girlfriend has a… superpower? Magical ability? Unique condition? We're not exactly sure what to call it. We discovered it a couple months into dating, when during a heated kiss, my belly started puffing up like a balloon, and the more she kissed me, the more swollen I got. We never managed to find out what causes this, but she learnt how to control her inflating kisses, so now she can only blow me up when she wants to.
And by God, she wants to, quite often. Not that I mind it - the feeling of my gorgeous girlfriend turning me into a hot air balloon with her lips is more erotic than any actual sex I've ever experienced. So, even though I'm sleepy as hell, I cave in very quickly.
“Okay, but you're getting me new pyjamas tomorrow,” I warn her softly. She kisses the tip of my nose with a smile.
“Of course, baby. Now, relax and pucker up.”
My lips open obediently. She grabs my jaw and presses her lips against mine passionately.
My stomach tightens under my lacy pyjama top as her magic air starts filling it. It slowly starts pushing against the material. I feel bloated and heavy right away as my belly rounds into a neat little gut, pulling my top tight around it.
My tits start to swell. They push forward, causing the lace against them to stretch. My nipples poke through my top, tight with both arousal and air. I wrap my arms tighter around my girlfriend's neck and pull her closer, pressing my bloating body against her.
“There we go,” she husks against my lips as she cups my straining belly. Her hands roam over the curve of my stomach, then slide over my waist that thickens noticeably under her hands.
“My sweet balloon. I'm so lucky that I can do this to you. Mhm, you're growing so fast.”
Her lips are back on mine. My hips widen as they fill with air. My thighs bloat into thick logs. She grabs onto them, kneads at the burgeoning flesh. The stitches on my pyjama bottoms are fighting for dear life when my ass expands. All that swelling, growing flesh is filling my clothes to their maximum capacity - and my girlfriend is nowhere near done with me yet.
Her tongue slips into my mouth greedily. I moan helplessly as she pumps up my body with nothing but her kisses, her hot mouth and her sheer arousal making me bigger and bigger.
The pyjama top is inching upwards and my puffing underbelly slips free. My shirt is shrinking more and more as my belly grows larger. It's soon nestled right under my ballooning tits. My girlfriend's hands explore my swelling torso with gusto. She kneads my heavy belly and bounces my taut tits, thumbs teasing my puffy nipples through my shirt. She's just as turned on as I am, if not more.
The stitches in my pyjama bottoms tear as my expanding hips and ass burst through them. My lower body bounces like a beach ball as my asscheeks puff larger, pushing me upwards. My swelling thighs spill out from under me, I'm turning into a buoyant pillow.
“Well, oops,” my girlfriend laughs devilishly. “Someone got too big for their breeches, huh?”
“As if it's not…” I don't get to finish my sentence because she kisses me again and sends more of her powerful air into me. My long-suffering pyjama top practically explodes off my airbags. My girlfriend tears the remains of my clothes off my body and throws them away. Her hands are even greedier now, the more naked and the bigger I am. She licks into my mouth possessively.
My belly pushes up against her, and she grabs onto it from both sides. My skin creaks when she digs her fingers into me, all that air stretching me to my limits as she turns me into an actual balloon.
Air is slowly filling up my arms and legs. They grow thick and wide and useless. My plump hands slip off my girlfriend's shoulders as they turn uncoordinated. There isn't much movement I'm still able to make as every single cell of my body fills with air. I'm stretching, growing, tightening, I'm way beyond human possibilities - maybe my girlfriend isn't the only one with the superpowers, after all. She can blow me up with a kiss, but I can puff larger than any other human being would be capable. And I can regrow, after she makes me so full that my body can't take it anymore. I hope it happens again tonight.
“Grow for me,” she orders between hot kisses. I can only whimper in response, my voice muffled by her kisses and my cheeks puffing up. There's barely any space left on the bed as my ballooning body slowly expands in all directions. My girlfriend presses her body into my swelling mass, panting in ecstasy. I'm her swollen plaything, her helpless balloon, a literal inflatable sex doll. And it turns us both on so much.
“I'm gonna make you so huge,” she twists my taut nipples and squeezes my bouncing tits. My eyes roll back in pleasure as she blows more air into me. My body creaks as it swells impossibly bigger. I'm becoming so huge, but I know we both want me to be even bigger.
She presses more kisses against my lips, and my body turns spherical. My swollen limbs are stuck against my massive middle. My belly swells so big that it nearly pushes my girlfriend off the bed. I can barely even see my surroundings anymore from the bloating, mountainous globe of my own body. I creak and whine. I ache everywhere. I'm so turned on I'm going mad with lust.
My massive bottom lifts off the bed as the air inside my body pushes me upwards and tilts my corpulent torso forward. My girlfriend doesn't let me float away. She kneels up on the bed and grabs my puffed-up face harder, devouring my mouth.
Arousal is dripping between my truck-tire thick thighs, my aching pussy trapped between massive and still growing flesh. One of my bloated sides is brushing against the wall as I'm inflating big enough to take up half the room.
“God, my beautiful blimp,” my girlfriend praises me and then kisses me more. My belly button pops out from the pressure. I know I'll soon follow and burst - and I can't fucking wait.
The parade balloon that I'm turning into creaks and groans as the pressure soon becomes too much. My puffing body knocks objects off the bedside table, pictures off the walls; the knowledge that I'm growing so big that I'm destroying the room around me would make me squeal with excitement, if my mouth wasn't occupied by inflating kisses.
“So fucking big, oh my god, baby, you're completely round,” she moans. Just a bit more and I know I will burst, the pressure building and building, my skin stretching to its absolute limits. My body fills up the room, my back is touching the ceiling now. I am so unbelievably massive, I can feel just how giant I am, how wide, and how impossibly full.
“Pop me,” I mumble against her lips, my swollen chipmunk cheeks making it difficult to speak.
“Anything for my sweet balloon,” she grins and then gives me one more big kiss. The pressure grows, along with my body, I'm so taut, so humongous, oh God, here it is, I'm too big…
Popping is a difficult experience to explain. It's like a very intense orgasm and surprisingly doesn't hurt as much as you'd think. It's a sense of absolute fulfillment, and then suddenly feeling light as a feather, and then complete blackout.
I have no idea how much time it takes in reality before my body comes together again. My girlfriend says that it depends on the size I've been blown up to. Since she made me enormous tonight, I assume my regeneration took more time.
When I'm back again, my body is back to its usual size. I'm lying in bed, dressed in different pajamas. My girlfriend has cleaned up the place, and now she's sitting next to me with the biggest smile on her face, her lips still red from all that kissing.
“Hello back,” she smiles and caresses my hair. “Do you need anything?”
I grin devilishly up at her. “Maybe a kiss?”
“What kind?” she asks, smirking.
“The kind that blows me up and away,” I say as I'm already pulling her down. Our lips meet, and I can feel her grinning against my mouth.
I close my eyes and melt into her as my belly slowly starts to swell again…
