Spike had read a story once about a giant dragon who’d carried the whole world on his back. He’d thought it was just a neat story back then, and he could care even less about fairy tales at his age, but it occurred to him now just how that dragon must have felt. Twilight’s one breast felt like the whole sky falling on him; a wave of warm, unrelenting fat. It wasn’t enough to floor him by a long shot, but darned if it wasn’t the heaviest thing he’d ever carried.

“Dragon strength, don’t fail me now.” He’d fallen to a knee at first, but as soon as he put his back into it, he could feel Twilight’s squishy tit moving up. “Ha!” He knew it. She was big, but not too big yet to crush him. All he had to do was start moving and he’d win the game easy.

“Hanging... hanging in there, Spike?” came Twilight’s voice from above. She sounded a little off. Was she...? No! He shook his head, trying to clear his thoughts. He had to focus! Twilight was probably just nervous that he was going to win.

“Gonna make you clean the bathroom!” he called, taking a solid step forward. Good progress. If he just kept his shoulders up and his feet moving, he’d be out from under here in no time. A good thing, too. The air under Twilight’s breast was only getting hotter and heavier from her own, all-encompassing body heat. “Ugh.” Mammals and their awful warm blood. “And the toilet too!” he groaned.

“Sure about that?” Twilight giggled, her chest bouncing softly on top of him. “Because aaaany second now...”

“Oh no...” Twilight’s breast, already the heaviest thing he’d carried on his back, was getting even heavier. He was still shrinking! The gap of light that represented freedom closed slowly as he shrank toward the ground. The weight of the world on his shoulders grew from ridiculous to impossible, and slowly he fell again to his knees.

“You can always give up, Spike,” Twilight sang. “I’ve got so many... mm... ideas for new games after this one.”  

“Never!” he shouted. But it was an empty bluff, and they both knew it. The avalanche of Twilight pressing down on him was more than he could take. Eventually his legs gave out, and Twilight’s warm breast pressed him into the desk. It didn’t crush him to death, like he’d worried it would — it was more of a big, absurdly heavy pillow than anything — but he was definitely at risk of smothering. It was pitch-black now, and the atmosphere had become a full-on sauna, with Twilight’s own sweat covering his body in a slippery coating.

He tried scratching at her like an angry cat, but that only seemed to spur Twilight on. “Keep... keep going, Spike!” she told him, her voice dulled by a thick layer of breast fat, and followed up by a muffled moan. “You can still... ah... you can still... mmmf...”

That bitch! She was getting off to this! “Twi—!” he tried shouting up to her, but there was no room to do that without a mouthful of salty breast sweat. Plan B, then. He clawed himself forward, finding a little purchase on the slippery surface of her boob, and slid up. If he could just keep going before time ran out, he could—

“If I’m right,” came Twilight’s muffled voice again. “It should happen right aboouuut...”

Oh no. Spike’s claws slid off her skin as he shrank again, and her breast caked him into the desk. “Alright, alright!” he shouted up to her, using all four of his limbs to push up as much slippery tit as he could. “I give up! You win, Twilight!”

The only answer he got back was another moan, and the world around him shook in response. She couldn’t even hear him! With no way out and no hope left, Spike took a deep breath of what thick, boiling-hot air remained around him, He let Twilight’s breast swallow him altogether, and focused on conserving oxygen.

“Time’s up!” came a booming voice from above. The voice giggled. “Looks like you’ve stopped shrinking. You got pretty tiny, didn’t you, Spike?”

Spike’s eyes snapped open. Light! Precious light! He inhaled. Air! Sweet, cool, delicious air! He was safe! He was free! He was... Hold on. He turned around to see a positively gigantic Twilight standing over him. He was screwed.

“You lost,” said Twilight, grinning down at him. A predatory glint sparked in her eye. “You know what that means!”

Spike gulped. “Another game?”

“Another game.” She nodded. “Same stakes as before. Only...” She hefted a sweaty breast, which seemed as big now as a hundred Spikes, and held its shadow over him. “You’re a little too small now to carry anything, so we’ll have to mix it up. I know just the thing!”

Her horn glowed, and in a flash of light, Spike found himself on a much softer surface than the hardwood desk. It was soft, bouncy, and warm, and the whole of it seemed to be covered in some kind of... purple... fur. He looked up to the ceiling. From the color, it looked like they were in Twilight’s bedroom. Twilight was lying on her bed, and he — he was on Twilight.

“Figured it’d be comfier if I could lie down,” Twilight boomed, her face blocked by two purple mountains in the distance. “The next game is mountain climbing!”

“And the mountains are...”

“These!” She picked him up by the scruff of his neck to give him an aerial view of her breasts — definitely mountainous at this point, and capped by swollen pink peaks taller than he was. She set him down at the base of her breast. “If you make it to the top, you win all the benefits from before. But if you can’t...”

Spike didn’t care to hear the end of that sentence. He knew the stakes. Victory had to come here and now, before Twilight put him through any more of her crazy games.

He looked up at the towering tit before him. If he won, he’d be taking Twilight much more seriously. And he’d put her on a diet. He’d made a couple of jokes about her udders before, but these were simply too big.

“Ready?”

He grabbed a tuft of purple fur from the base of the breast. It was slippery and sweaty, but if he could get a decent enough grip on it, it would be possible to climb it... Hopefully. “Ready!” he shouted.

“Go!”

Spike grabbed on and pulled himself up. One claw, one foot, other hand, other foot. He worked his limbs in a slow and careful rhythm, saving his strength and making steady progress.

“Keep it up, Spike!” came Twilight’s voice from the other side of the mountain. “It tickles!”

“Yeah, I’ll bet,” he grumbled, digging his claws in extra hard. Maybe Twilight had remembered, or maybe she hadn’t, but mountains were a dragon’s natural habitat. There was no way he was going to lose this, and she'd deeply regret everything she’d put him through after he won. Somehow.

He took a second to wipe his brow, taking a look at the purple-fur ground below to check his progress. Not a lot, but the only real obstacle at this point was just how much he had to climb.

A minute or two later, he’d made it a good ways up Twilight’s ‘mountain’. He was maybe halfway there, if the twin peak beside him was any indication, and he still had strength to spare. The faint hope in his chest swelled further. He was going to make it!

Unless Twilight had anything to say about it, of course — and she did. “This game’s looking a little boring for me,” she rumbled. “You can keep playing, Spike. I’m just going to make some of my own entertainment.”  

“What’s that mean?” he shouted. No answer came, but the hand descending on the neighboring mountain gave him a good idea. He could see Twilight pulling and pinching at her nipple in the distance, and if her earthshaking moans were any indication, the other hand was somewhere further south.

“Keep going, Spike!” she groaned. “If you stop now, the... mmm, oh! The earthquake might get you!”

That was good advice, loathe as he was to admit it, so he returned to climbing. One claw, one foot, other claw, other — whoops. His foot slipped as the mountain jiggled under him. Twilight wasn’t directly interfering with his efforts to climb her, but her antics were definitely having an impact on his climbing.

Still, he could pull through. He set his foot back on the warm swell of her breast and locked it in place. One claw, one foot, other claw, other foot. He just had to maintain the rhythm, ride out the worst of the boobquakes, and he’d be golden. There it was, just ahead! The mountain was curving, and he could see the tip of Twilight’s erect pink nipple. He was going to make it!

But it wasn’t to be. Spike should have realized by that point that all hope was temporary. One claw, one foot, and a deluge of something thick and salty rained on him from above.

“Oops!” came Twilight’s voice. “Soooorry, Spike!”

“Agh!” He spat out as much of sticky liquid as he could, and used a free-hanging claw to wipe his eyes. What was all of this? Glue? No, Twilight had been lying here with him the whole time. She couldn’t have gone to get anything. Where was all of this coming from?

...Wait. His eyes widened as he looked to the shadow above him. Twilight had moved her sticky, cum-drenched hand just over his... and another drop was falling off.

This wave was even thicker and stickier than the last, filling his mouth and drenching him from head to tail in Twilight’s essence. It wasn’t glue, but it may as well have been, and the force of the drops were threatening to break his grip on the mountain.

“That’s cheating!” he sputtered. He’d spat out most of Twilight’s marecum, but the taste still lingered. “Twilight!”

“All’s fair in love and war,” Twilight sang. “You should be proud, though, Spike! I haven’t been this wet in months.”

Spike wasn’t feeling very proud at that moment, though. Particularly not as a third and final drop of marecum fell from her finger. The biggest of them all.

There was no hope. The sticky droplet tore his grip from the mountain and carried him all the way down to the summit, leaving him buried in a sticky puddle of Twilight-juice.

“I think that makes another win for me!” Twilight cheered. She brought her soaked hand down and stuck Spike to the finger. “Another game, Spike? I’m feeling really lucky today!”

“Please...” he gurgled. There should have been a no at the end of that, but there was too much gunk in his throat to say any more.

“If you say so!” Twilight said happily.

She leaned over and wiped him off on the sheet between her legs. From the puddle of marecum, Spike staggered to his feet. Warm... she’d put him some place warm. He brushed the juices from his eyes and stared up at the next ‘game’ Twilight had prepared for him: her own pulsing pussy, big enough to swallow him whole and already drooling in anticipation.

“You ready, Spike?” Twilight called, her boulder-sized clit throbbing with need. “‘Cause I am!”

“Ready...” Spike sighed. It was going to be a very long day.
