Rainbow Rocks her World presents: Twilight and the Magic of Estrus

Twilight trotted up the road to Applejack's farm happily, now back to her svelte figure after having Rainbow Dash's baby-and Dash hers, of course. The only difference she kept was the bigger, milkier teats. She enjoyed them, and it seemed, so did any of her bed warmers. Being both royalty and a hot little nerd meant she had no shortage of admirers, and was very much enjoying dicking her way through Ponyville.

A full year had passed since the last of Rainbow's conquests, Ponyville now full of her brood. She was a rather good parent, and her speed meant she could race from place to place so none of her foals felt left out. Today was Rainbow's day with their foals, and Twilight planned to take full advantage of that fact.

As she trotted up to the barn, she paused to admire Applejack moving hay bales, muscles rippling under taunt, sun warmed skin and fur. Before she knew it, Twilight was sliding free of her sheath, one hoof rubbing at her balls and drooling pussy. She'd hit her estrus again, and decided to do an impregnate tour of Ponyville like Rainbow had-she'd just seemed to have so much fun!

Big Mac was the one to find her, perving on his sister and fuckbuddy. He snorted with amusement, Twilight so into her play she didn't notice, and then nudged her busy hoof with his muzzle. She put it down, flagging her tail and spreading her hind legs, not even bothering to look behind her, just hoping for a fat slab of cock-which is exactly what she got.

He mounted her from behind, his long equine cock nuzzling at her soaked folds. She closed her eyes, wings up in a wing boner, and pushed back, sliding onto his cock as he slid it into her. He gripped his forelegs around her middle, thrusting slowly, enjoying the feeling of pussy, clenching at him, and the feeling of fucking a princess.

He leaned forward, grabbing a mouthful of mane, and yanked on it in time to his meaty thrusts, making Twilight moan and yelp, loving it. Her pussy worked his shaft, practically milking him for his seed. He snorted, balls tightening, surprised when she used her magic to pull him out of her pussy and balls deep in her tight, little used asshole. He whinnied, giving her a creampie almost immediately, only managing a brief flurry of thrusts into her depths before the grip and warmth over whelmed him and he shot rope after rope of thick, potent earth pony seed into her asshole.

She sighed in relief, having reached orgasm herself when he plunged it in her asshole, enjoy the brief respite of overwhelming desire. She pulled off, cleaning him off with her magic. "Thanks, Mac! Sorry I can't let you cum inside, Celestia and I want to carry each others," he smiled, "Ain't you worry, princess-I enjoy a good round a the ol' cornhole," he assured her.

"Well, come help me fuck Applejack anyway-Dash enjoyed her time sharing with you," she added, the bookworm blushing. Having got rid of a lot of her lust build up left her more lucid, but the fire in her doubled loins was building even now-and the feeling of hot, thick, earth stallion jism deep in her bowels added fuel to that fire.

He pondered this, before nodding. He took the lead, lifting his own tail to get a good look at his thick sheath, and plump, hanging balls. She noticed he also flashed her his tight looking asshole, and wondered if he enjoyed the same assplay her brother did. Allegedly! She added hurriedly to her own thoughts. She wouldn't know that. Of course not.

She started, having to gallop to catch up to Big Mac. Applejack was sitting on her haunches, one hoof clopping herself enthusiastically. It seemed she'd caught their little show. Twilight paused to admire her. Little had changed about her during the pregnancy that had stayed, but those now much fuller teats appealed to her immensely. She trotted up, wings flared excitedly.

"I wanna get you pregnant!" she declared, before blushing, wings tucking in again. "I, uh..." Applejack chuckled, "Gonna fuck around Equestria like Dash did huh? Well, long as you pay child support and keep in their life, ah don' see why not...mighta enjoyed bein' a hot lil milf more'n ah expected," she admitted.

She laid back, opening her hind legs wide. "C'mon then...let's expand our family a lil more," she offered, eyes lidded and voice husky. Twilight pounced on her, her own tail flagged up over her back, Big Mac enjoying the goo cocktail smeared all over her flanks and legs.

Twilight sank her girl cock into the tight, soaked folds of Applejack's milf cunt, the earth pony's previous clopping leaving her well lubed. Twilight thrust in and out of the heavenly hole, her thrusts showing off her virile sack and winking pussy to Big Mac, who took the invitation. He mounted her as she thrust back, the fat stallion cock sinking into her ass. She moaned, her hips moving back into the cock and forward into the pussy.

Big Mac leaned forward, gently preening Twilight's wings, the alicorn mewling, the gentle ministrations sending her pleasure even higher. Her wings fluttered, but he was careful, not a feather out of place or yanked on. She gripped her anal muscles, giving his fat cock more stimulation, Applejack able to feel his cock in Twilight's stomach where the alicorn lay on her. It gave the act an extra layer of sexiness, like the incest.

Twilight rutted hard, eyes rolling back at the clench of applebucking honed muscles, and Big Mac's deep, long thrusts into her gut. She'd be gaping all the way to her next conquest, and the idea aroused her-she hoped Celestia left her cunt just as gaping and drooling seed.

Big mac pushed Twilight down atop his sister, his thrusts forcing her to fuck Applejack, pounding her good and hard, transferring that to Applejack. The mares moaned, writhing against each other, until Mac held Twilight still and blew another load into her plothole. He pulled out, snorting, going to Applejack's head where she began to clean his shaft with her tongue, Twilight fucking her again.

"Oh, Applejack...I'm gonna cum...I can't stop thinking about knocking you up and it makes me so horny! A whole herd of my children, I'll surpass Rainbow even! Oh...oh! Here it cums, AJ!"

Applejack finished cleaning her brother in time to hug Twilight tight to her taunt, muscled body. "Do it, Twi! Cum in my milf pussy, knock me up again! Gimme your fertile seed, plant it in my soil!"

Aj's encouragement had Twilight cumming, cock head pressed against the other's cervix, cumming right up against it. Twilight collapsed on her, the pair cuddling as all three caught their breath and let the seed do its work.

"So...how's little Zap?" she asked, Rainbow's child by AJ spent a lot of time on the farm, since her mother did too. She was a rather large pegasus-most likely Mac sized when grown, with rainbow pastel hair and AJ's own orange coat.

"Doin' well-wings finally grew out right, had Rainbow in a right tizzy until then," she chuckled. The pair disconnected, cum connecting them before the string broke.

"Oh! Did you get the wedding invite?"

"Sure did, glad it's next week-won't be showin' yet, Rarity'd make me her next dress if I had to ask for another!" she laughed, all three now laying under the tree, in the shade.

"Well, I need to get measured for my dress at the castle-Rarity's there for a bit." she grinned, "I think we'll pencil in some...affection,"
