She moved one hand to fondle at her sack, making a loud slosh and gurgle sound. “Hear that? That's mah bro quickly gettin' turned to spooge!” She wiggled a bit, showing off the slowly shrinking bulge. The definitions on the trapped stallion rounded out and became less defined. Despite the futility of the whole situation, Big Macintosh kept fighting.

“AJ! You gotta let me out!” came the loud complaint, the stallion pushing against the smooth orb he was trapped in. His transforming body softened, making escape impossible. His red coat, those parts that were still fully pony, quickly turned white and softened more and more. His words turned to gurgles as he dipped below the surface of the cum around him, his weak fighting as well as his words just turned to loud gurgles.

Applejack just patted her swollen balls gently as she skated off the track and quickly changed out of her gear. She slipped on a bra and shirt, but opted to go without pants. With how swollen her balls were, they wouldn't have fit in them anyway. “Don't you fret, now,” she replied to her brother. “Luckily, ah figured out how ta get around the inevitable. We'll be without ya for some time, but you'll eventually be back.”

After she was dressed, she dashed out the arena and made a beeline for Sweet Apple Acres. Each footfall was punctuated with loud sloshes, glorps, and gurgles as the pony inside her sack was quickly getting turned into potent, virile cum. His fighting slowed as time went on; the journey to the farm was long enough that, by the time the pair reached her, there was only one pony left. Quickly she ran upstairs and knocked on Applebloom's door.

“APPLEBLOOM! Open th' door, git nekkid, and bend over NOW!” she shouted through the door.

“A-Applejack? What's goin on!?” came the surprised response as Applebloom opened the door, completely naked. She didn't have quite as big breasts as her sister, and her cock was much smaller, but despite these, Applejack would have to make do.

“Yer durn fool o' a brother was th' one that done challenged me ta' the match! You can guess who won. Now quickly, ah feel like ah'm about ta burst!”

Applebloom still had a confused look on her face. “But how can AH help?” she asked over Applejack's needy whimpers, watching her starting to slowly stroke at her cock. “OH! Ya need help gettin' off, dontcha?” Quickly she knelt in front of her big sister and opened her mouth, dragging her tongue up along that member. It twitched and throbbed as pre dripped out the tip. Applejack almost came right then.

“A-Applebloom, no... not like that...” Applejack moaned out, right on the edge. “W-we n-need yer brother back... n-not swallow him down...” she managed to pant out. She was almost too aroused to stop herself. “T-turn around quickly... ah'm about to pop!”

Applebloom quickly nodded and turned around, lifting up her tail. “Oh! You want me ta-” Her words cut off when she felt the slickened tip part her folds and half of her sister's cock buried inside of her. Applebloom pouted a little, huffing out a small complaint. “No foreplay?”

“No time!” came the rushed, moaned reply, the larger, older mare already thrusting into her younger sister. Beads of sweat formed on both their bodies as the two rutted fast and, after a few seconds of thrusting, Applejack's words were proven true. Her tip flared wide as her overfilled testicles released their load, pumping the smaller mare full of the cum. There was so much that her belly quickly rounded out, a tiny bit dripped out from around the cock buried inside Applebloom. Applejack slowly fell to the floor, pulling Applebloom with her. She cuddled with her and nuzzled her. There was another huff from the younger sister.

“Aw, Applejack! Ah didn't even get off!”

“Ah'm sorry, sugarcube, but this wasn't about yer or mah pleasure, we had ta' save yer brother. OUR brother.” Slowly Applejack stroked over the rounded belly and smiled. “I think we got ya knocked up, we'll just have ta make due for a few months with just you, me, and Granny.”

Author's Note

And when Big Mac was born, Applejack remembered that he'd still be too young to help with the farm for a few years. But at least Big Mac survived!
