Royal Service

~ ⏣ ~

The next morning, after a bit of extra shenanigans with their partners, Pound and Pumpkin shared breakfast with Flurry Heart. Unfortunately, that was all they had time for, since the twins had classes the next day, and thus had to take the train home.

Flurry accompanied her friends to the station. She gave Pound and Pumpkin a hug, saying her farewells. "Thank you guys for coming! I had a lot of fun."

"Yeah, us too," Pumpkin said, chuckling quietly. "Do you think… we could do this again?"

The alicorn laughed as well — a pleasant, musical sound. "Hehe, of course! As soon as we can find some free time." Taking a devious look, Flurry whispered in Pound's ear, "And, next time, you're sleeping with me. Promise!"

Pound Cake immediately turned red, looking like his brain had blown a fuse, which greatly amused his sister.

"Let us know how… well, you know… how things are going." Reflexively, Pumpkin checked out Flurry's lithe midsection, which would undoubtedly bulge quite a bit in the next eleven months.

"And, uh… also…" Pound scratched his head, unsure how to approach the topic.

The Princess smiled knowingly. "I'll keep you informed of how Mist and Spinel are going, don't you worry." She added a wink for good measure.

On the platform, the train conductor rang a bell, calling passengers for Ponyville to board immediately.

"Alright, alright, you two don't want to miss the train. Let's write each other soon, okay?"

"Yep, see you soon, Flurry!"

"Yeah, until next time!"

With that, Pound and Pumpkin grabbed their bags and stepped in the wagon, settling in for the long ride home.

Several hours and one uneventful train ride later, Pound and Pumpkin were back in Ponyville. It was now the middle of the afternoon, and the Sun shone brightly over the peaceful little town. It was a stark constrast to the frozen wastes of the Crystal Empire.

The twins trotted home with their luggages. Sugarcube Corner was busy as usual, and they said hello to their parents before retiring to their room.

"Aaahh!" Dropping his bag on the floor, Pound flopped on his bed. He laid there belly up, his wings lazily sprawling on either side.

"Oh, c'mon, you lazy colt," his sister said, rolling her eyes. "You could at least unpack your stuff before going for a nap."

Pound yawned. "Meh… I'll do that later. After everything we did, I'm kinda beat, you know? Plus, unlike you, sis, I can't just magically zap all my stuff back in the drawers."

"Oh, you poor thing," Pumpkin mockingly teased him. "All you have is the ability to fly. Must be so hard being a pegasus."

Pound waved dismissively, setting his head down on the pillow. Soon, his thoughts began drifting to all he had experienced during the last couple of days. He could barely wrap his mind around it: he had mated with several mares, probably impregnated two of them, had a been sodomized by a stallion, had been fellated by his best friend Flurry Heart (and his own sister), and had seen the Princess herself get impregnated by all her stallions.

Not really thinking about it, Pound caressed his sheath. His penis felt sore, and his testes were almost painful, yet the tip peeked from its hiding place all the same. Absent-mindedly, Pound rubbed his flaccid cock, watching it spill over his stomach.

The pegasus' reverie was interrupted by Pumpkin's giggle. Pound had never minded his sister seeing him — especially not after what they'd just been through —, but he wasn’t keen on having her mock him either. He frowned at Pumpkin. "What?"

Pumpkin covered her mouth, but that didn't completely cover her amusement. "Really, bro? You haven't had enough?"

Pound shrugged. "Yeah, kinda. But, it's sad it's over already. We might not get another chance in a while."

"Haha, yes. I know. I'm just messing with you. Honestly, I've been trying the whole train ride not to wet my seat. C'mon, move your butt and leave me a bit of space." Not waiting for a reply, Pumpkin hopped on Pound's bed, arching her spine and sprawling on her back.

"Uh, really, sis?" Pound said as she dipped her hoof in her vulva. "You have your own bed, you know?"

"Pfft, don't tell me you're shy now?"

Again, Pound didn’t answer. Truthfully, watching Pumpkin masturbate felt nice, and so was the soft touch of her fur against his own. With a sigh, Pound stroked his cock with a bit more vigor.

"Unf… ah!" Okay, fair enough: Pumpkin's breathless little gasps were pretty cute too. Side by side, the twins masturbated together for a while, each tending to their own pleasure.

Soon, the scent of Pumpkin's vulva pleasantly teased Pound's nostrils. She rubbed her sex with tender care, her hoof getting coated with a slick sheen. Pound masturbated, staring down his belly as his hoof went up and down his erection, sometimes glancing at his sister. A dollop of clear, sticky liquid oozed from his urethra.

For several minutes, they pleased themselves without a word, until Pumpkin spoke again. "Uh, Pound? You know, we could just… erm…"

Pound froze instantly, forehooves halting midway down his cock. "Er… I'm your brother, remember?"

"Well, duh! But so what?" Pumpkin got up and straddled her sibling. "It's just the two of us, there's nopony else around. I'm a girl, you're a boy; we might as well enjoy it! C'mon, what do you say? We can at least try once."

With some hesitations, Pound fondled her pussy. It was warm and soft, just waiting to be filled.

"Here…" Pumpkin rose and grasped his erection, lining it up to her vulva. Her labia kissed Pound's tip. Pumpkin waited for an answer, but her brother provided none.

He did not protest either.

Pumpkin sat back down, taking Pound's stallionhood within herself. The pegasus watched as his penis disappeared inch by inch inside his sibling. Pumpkin's vagina caressed his cock, her inner walls feeling so soft, so welcoming.

"Oh, damn, that feels good…" Not wasting any time, Pumpkin started a gentle bounce, straddling Pound and working his penis in and out of her pussy.

Pound moved in unison with his sister, thrusting up with his hips as she pushed down, then pulling down as she went up. With all the experience gained while at Flurry's castle, the motions of sex came easily for the twins. They worked in tandem, enhancing their mutual pleasure.

Ridden by Pumpkin, Pound had a gorgeous view of where their bodies met. Poking from her puffy slit, his sister's clit winked constantly. Wanting to try something, Pound used the tip of his wing to caress Pumpkin's engorged nub. Pumpkin trembled atop him, cute little coos coming from her mouth.

On the downstroke, Pound pushed up with more force than before. Pumpkin gasped and fell on him. Pound hugged her tightly, wrapping his forelegs around her withers and his hindlegs around her rump, keeping his sister as close as possible. He buried his muzzle in her mane. From this angle, Pound couldn't penetrate his sister as deeply as before, but they made up by increasing the speed of their mating.

Suddenly, Pumpkin's face was so close he could see every detail of it, from her flushed cheeks to her beautiful blue eyes. Her mouth was slightly open, her breathing quick from exertion. "Pound, you… you close?"

"Y-Yeah… And you?"

"Uh-uh!" Then, eyes shut, Pumpkin kissed him. Their tongues met, and the twins made out passionately, not slowing down their rutting one bit.

Pumpkin came first. Marecum splattered Pound's sheath and testicles, her moans muffled in her brother's muzzle. Her entire body shook, and her sex convulsed, but Pumpkin continued to fuck, determined to have her brother orgasm.

Her motions were getting sloppy, and exhaustion settled in, but Pound was happy to oblige. With a powerful grasp, he held Pumpkin down on him and pushed his cock deep within her pussy. Pumpkin's cervix, loosened by estrus and passion, offered little resistance, and Pound's glans flared in her womb. With a pleased, relieved sigh, Pound ejaculated inside his sister. His balls twitched, and sperm gushed from his urethra, coating Pumpkin's uterus with goopy strands of cum.

Both twins relaxed, and they cuddled tenderly. In bliss, Pound simply let his seed flow, while Pumpkin enjoyed the creamy warmth her brother was leaving within her womb.

"Unf… ah… ah…" Breathless, Pumpkin laid her head on her brother.

Having finished ejaculating, Pound gently caressed her mane, his stallionhood softening in her vagina. Suddenly, a worrying thought crept up in his mind. "Uh, sis… Aren't you in heat?"

Pumpkin let out a faint giggle. "Heh, yeah. But I'm still taking the potion Flurry gave me, dummy, so don't worry: I'm not gonna give you foals."

"Oh, good…" Relieved, Pound continued to pet his sister, enjoying their shared afterglow. The bedroom was utterly peaceful, and Pumpkin's heartbeat was incredibly soothing. He held her tenderly, caressing her soft mane, his flaccid cock resting in her sex.

…

…

"Hey, Pound?"

"Uh?"

"We should do this again."
