She gently wrapped her hand around my cock. I grew hard as she slipped under the sheets and began to rub me up and down, her pink lips parting in a grin.

“I’ve got something special for you”, she smiled, leaning into my side. I could feel her warmth on my shoulder. I was naked, she was wearing a tight tee, her small breasts rising up and down as she breathed.

“Watch.”

As she rubbed my cock up and down, she closed her eyes, her breathing slowing, the rising in her chest becoming slower and more gentle as she began to focus. She slowly worked my shaft, and I felt the endorphins fly as I began to get more and more aroused.

Her breathing remained the same, but her chest began to rise and fall more deeply, but now every fall was smaller than the previous rise. I didn’t speak. I couldn’t. Her chest rose and rose, as she slid her wrist up and down, the continual arousal flooding through me. It was getting bigger. She was getting bigger.

I grew more and more sure of it. I said nothing, not daring to break the spell – her breasts were inflating with each movement of her wrist. It was like I was pumping her up, or she was pumping herself up. As my cock grew more and more hard, I felt her burgeoning chest slowly expand into my arm, pressing into it with a mass of solid, firm breast that began to nudge into me more and more as she went.

I couldn’t believe it. She was blowing up. Bigger and bigger with each stroke of my dick.

I watched out of the corner of my eye as her tits grew larger and heavier, pressing more and more into my arm, bulging out through her tight tee, spreading over my arm as her mass increased. I was amazed how much I loved watching it press into me, my arm looking smaller and smaller as her breasts expanded.

There was a stretching sound as her bust grew bigger and bigger, her t-shirt groaning under the strain, pulling further and further away from her slim body as her boobs continued to grow, her cleavage deepening as her low-cut top stretched out in front of her. I watched as her tits started to bulge into each other, a deep, rich seam of cleavage developing as they grew more and more expansive.

All the while she had her eyes closed, but moved closer and closer to me, resting her head on my neck as her breasts ballooned larger. It was like every pump of my cock was blowing them up, and I couldn’t stop watching them grow bigger and bigger, pulling the fabric of her shirt tighter and tighter with every quarter-inch they expanded.

They were already large for her slim frame, swelling out like two balloons, filling up with mass. I could feel their increasing weight press onto me, two swollen melons growing in size, two huge orbs of breast getting larger and larger.

I willed her to increase the speed that she worked my cock, desperate to see what that did to her expansion, and she soon obliged. Moving faster and faster, her tits started to wobble in their cotton prison, shaking to either side like the big, heavy bags of flesh they were. I loved the feel of their big, fat mass curving into me, taking up more and more space in the bed as she grew.

My dick grew harder and harder, getting closer and closer to exploding as she ballooned next to me. I could barely breathe, not wanting to make the slightest bit of noise in case it distracted her from her mission. She sped up.

Her massive fat tits swung and wobbled, beginning to eclipse her lower half as they grew further and further forwards. I could barely fathom how big they were now, two fat melons packed into her struggling top which was bursting at the seams as her huge, creamy breasts stuffed it to the max, her bulging cleavage pouring over the top, the line of her v-neck creating a dent in her massive boobs, which curved over and under it, almost angry at the insubordination that prevented them showing their true size.

And still she rubbed my dick, sending me into a frenzy of lust. I was breathing deeply, my own chest rising up and down, a pale imitation of the enormous size hers now was. And it was still growing.

I looked over at her and her eyes were still closed, her lips pursed together, her whole being deeply concentrating. I looked down at her enormous cleavage and almost came there and then.

Her tits were so huge now. Her shirt was beyond stuffed, her massive jugs spilling out the top, pushing the whole garment outwards with their expansive size, threatening to tear it open. I knew that wasn’t actually going to happen, but sooner or later they’d be too big for it and it’d be too hard to take off. The mass of breastflesh beneath it was becoming too great. I felt myself getting even closer to blowing my load.

And then she sped up.

Her hand was going like a jackhammer now, her fat tits shaking and wobbling all over the place. I couldn’t believe how heavy they were when they swung into me, like massive hackeysacks that hit hard, shaking and jiggling all the while. Watching the huge, still-growing masses of flesh vibrating and bobbling about reminded me of some of the videos I watched on YouTube, where a camera is attached just in front of a huge chest while someone walks. It was always a secret turn-on of mine, and now I had a front row seat to the biggest boobs I had ever seen, shaking and jiggling growing bigger all the while.

I shifted on the bed, writhing with pleasure as my entire body prepared for a massive orgasm. She clung onto my cock with a tenacious grip, clearly as desperate as I was for her to keep expanding.

I realised she hadn’t opened her eyes yet, and so had no idea how big she’d gotten. I estimated her tits were J-cups at the very least, massive swollen mounds of boob that looked ridiculously big for her frame. I could hear the bed groaning and squeaking at having to support all this new weight, and that only made me more aroused.

Her tits started to bulge up and out the side of her t-shirt as they became ludicrously large. It was turning into a sort of bra as they got bigger and bigger, eclipsing her legs as they swelled outwards. Each tit was bigger than her head now, and still growing. And still she jacked my dick up and down.

It was sticking directly up now, rock-solid and ready to come. She went deeper with her wrist movements, creating the thunderous beginnings of my orgasm by slowing things down a little, and making her expansion noticeably more sizeable with each deep movement.

By now, she looked to be more breast than woman. She’d never be able to see her feet unless she bent over, and that would mean swinging her huge udders down into her thighs, threatening to pull herself over. I loved the thought that she was too big to navigate herself around. She was going to be ruled by her tits. I’d serve her every need, just to be in her presence. And still she was growing.

Her tits were shaking madly now, her shirt constricting her breathing. Her breasts were everything now – I couldn’t think of anything else as I watched her stupendous cleavage as her tits bubbled over the top of her shirt, slamming madly into each other as they shook and jiggled with every movement of her wrist. There was no space between them now; there just wasn’t room in her pitiful shirt.

I could feel it. I tried to put it off as long as I could, but this whole thing was arousing beyond anything I’d ever imagined. I wanted to never come, for her to keep growing exponentially larger, but every time I thought about that, about her being so big she couldn’t move, about her stuck in bed with breasts bigger than the rest of her put together, my cock pulsed, and I brought myself closer to orgasm.

It was a horrible paradox; punishingly arousing.

My dick tensed, preparing to blow its massive load, and she breathed deeply through her nose, knowing what was to come. Still working my rock-hard shaft, she slipped her left leg around over me, straddling me as I sat on the bed, her hand rubbing my cock faster and faster, facing me, giving me the most incredible view I could ever have imagined.

Those colossal, impossible tits were right in my face, wobbling and shaking and growing larger with every second, occasionally being hit by the top of her hand, sending the whole titanic mass shaking as she jacked me faster and faster.

They were too big. They were all I could see. She leant back, thrusting her chest forwards, and buried my face in her gargantuan cleavage. I couldn’t see anything, just feel the warm, enveloping embrace of a sea of tit, surrounding me on all sides, deep and firm and perfect.

And I could feel it growing. Swelling, bulging into my face, getting bigger and bigger and she raced her hand over my cock, tipping me over the edge.

As her breasts ballooned into my face, I could only imagine how huge they’d become, and that thought was the last straw. My cock hardened for the last time, and I felt it pulse with semen, and fire the first, beautiful load into the base of her humongous jugs.

She breathed deeply with arousal and appreciation, maintaining speed over my cock as I came again and again, firing bolt after bolt of hot, thick semen onto the underside of those beautiful fat tits, smearing their enormous mass with the most powerful ejaculation I’d ever known.

The aftershocks continued for a while, and then my dick finally stopped shooting its load, her hand only then slowing down as the final dribbles leaked out over her undoubtedly cum-covered hand.

The last few gentle pumps of my cock resulted in the final growth of her breasts, which were pressed firmly against my face, still gently pulsing bigger and bigger, filling my entire vision, making everything black. They smelt of her perfume, and I knew there and then that she was mine and I was hers. This preposterously-busted goddess was going to be there for me.

And she was going to grow even bigger. Instinctively, I knew that.

And slowly, ever-so-slowly, she removed her sticky hand from my cock, and pulled her enormous breasts away from my face.

It was a matter of moments before I grew hard again.

And she grabbed my tumescent dick once more, and smiled.

We were both ready.
