Team Illusive dragged their paws as they returned to their room in the guild after a long, grueling job rescuing a shinx from deep within Sheer Mountain Range. Composed of an umbreon, espeon, and eevee, they weren’t exactly the most versatile of groups, especially since Umbra’s little sister, Ollie, needed constant attention lest the teammate-in-training get hurt.

As if keeping an eye on the eevee and making sure to keep her out of trouble wasn't exhausting enough, Nebula also had Umbra's heat-induced nagging to contend with. He loved the umbreon, really, he did, but her constantly flagged tail as she whined about the length of the mission was horribly distracting.

What male wouldn’t be distracted by an ass that fine?

The mission reward had been worth it though. While the monetary compensation for a job well done was nice, there was nothing quite like the satisfaction of a successful rescue. Little Riley’s parents were ecstatic to be reunited with their adventurous daughter, and even Umbra paused her horny complaining to smile at the family. 

Arriving back at their room in the Guild, Umbra was the first to collapse onto their large straw bed. “Finally!” she moaned with a dramatic groan, leaving nothing to the imagination as she rolled around on her back, all twelve of her nipples fully erect as her dark, puffy spade twitched and throbbed between her hind legs, drooling arousal all over her thighs. “Hurry up and fuck me, I really am not in the mood for foreplay.”

Ollie, who had been snoozing on Nebula’s back the entire time, was roused by her big sister’s demand. She stretched with an adorable yawn, and then jumped off his back to pad her way over to her needy older sister. Without hesitation, the eevee climbed onto the umbreon’s belly and pressed her small vulva against Umbra’s heat-swollen one with a lewd squelch.

“Do me too!” Ollie chirped once she was in position, glancing back at Nebula with stars in her eyes. She continued to grind herself against Umbra, giggling all the while. “You’re squishier than usual, sis!”

Umbra wasn’t quite as enthused. “Seriously, Ollie?” she complained as the eevee humped her with practiced motions. “Can’t you join us later? I just said I’m not in the mood for foreplay! You know what heat does to me! Ugh, we really should have dropped you off with Tina…”

“You won’t even notice I’m here!” Ollie countered happily, still humping her sister as though it was the most normal thing in the world. “Hehe, betcha I can make you cum without Nebula!”

The sight of two pussies pressed together would have been enough for any male, but such a young eevee doing and saying such crude things riled Nebula up like nothing else could.  

The squishy noises of their incestious sandwich perked his ears further, his erection growing to half-mast as Ollie fucked her sister with skills born from forbidden years of practice that probably shouldn’t have existed. 

Ollie’s giggles eventually morphed into surprisingly deep and needy moans, betraying the outwardly innocent eevee’s lustful side. Even Umbra was getting into it, letting out soft moans of her own as her sister’s tiny tapered tip teased her entrance, threatening to pop inside at any moment. 

Eeveelution pussies truly did have the most glorious shape.

Unwilling to watch from the sidelines as the two had fun without him, Nebula stepped in and mounted Umbra, squishing Ollie under his chest in the process. He hooked his forelegs around her belly and jerked his hips forward. Sliding his dick between the sisters’ warm, squishy spades in one smooth motion, he drew a gasp from all three of them.

Ollie’s minuscule spade immediately burst into twitches against the top of his length. “Yesss!” she cried as she climaxed. She always had a hair trigger. “Soooo good! Put it in me, in me, in meee!”

“Sh-shut up, sis,” Umbra growled at the eevee, understandably so. Ollie always tried to steal his attention. It would have been adorable if it didn’t upset Umbra so much. “I’m the one in heat, not you! You’re lucky you’re even a part of this! J-just, enjoy your orgasm, you little sneak.”

“Fiiine!” Ollie huffed. “But I get him to myself later! I can totally take his knot now, I practiced!”

“Ugh, deal!”

Nebula chuckled as they bargained over him like he was a juicy, tasty berry.

Ollie’s been particularly needy lately, always trying to woo him in increasingly drastic ways. Flashing him in public, making sure he was looking at her during their pee breaks, even marking him with her big bushy tail to make sure everyone could smell her on him. He suspected the eevee was nearing her first heat. Her scent was stronger, her libido increasingly difficult to keep up with, and the crush she’d had on him for years seemed to have become something… more. 

The signs were clear, Nebula decided, and he knew he’d have to be careful. Unsafe sex was doubly so when unevolved. They had plenty of contraception seeds, but those had to be taken before sex to function. Not to mention their dubious safety during someone’s first heat.

But here he was, gripping Ollie tightly as he humped away, not a care in the world. His knot was already beginning to swell, expanding between the two sisters as he used their plump mounds to get off.

Ollie wasn’t passive, though, humping back with equal enthusiasm, all the way toward what was clearly a second orgasm.

“Save some for later, why don’t you?” Nebula teased as he licked the back of her head affectionately.

“S-sorry.” Ollie huffed and trembled, her spade twitching against him. “It’s just sooo good! Gonna put it in Sis yet? Huh? Are you gonna?”

“Good question, Ollie!” Umbra growled, clearly annoyed with all the foreplay. “Are you gonna put it in?”

The umbreon glared at him, as though daring him to wait any longer. He probably should ‘put it in Umbra’, dangerously close as he was to spilling his seed all over the girls’ bellies. 

He stopped his thrusts with a grunt and pulled back until his tip poked Umbra’s warm entrance. Lining himself up was easy after all the times they’d mated, but Ollie’s presence presented some unique challenges. Even smothered under his bulk—though the eevee didn’t complain—she managed to squirm enough to make him miss, deflecting him up and into her spade instead.

Hot, squeezing, and wet, the eevee’s innards welcomed him greedily. Ollie took advantage of the accidental penetration by immediately pushing back,doing her best to take him deeper. She only managed to take his tip before he pulled out and aimed back down toward Umbra’s spade instead, his cock dangerously close to orgasm due to the underaged tease. 

“Aww, man,” Ollie whined when he pulled out, losing her chance to be stuffed. “I totally could have taken you, too!”

“Stop trying to steal my mate!” Umbra growled at Ollie. It was especially effective since they faced each other, and Ollie’s ears lowered as she was chastised. “And Nebula! I swear to Arceus, if you do not put it in right now, I will bite you!”

Peering at Umbra over the back of Ollie’s head, Nebula grinned and thrust, sinking deep into Umbra’s squeezing depths, claiming her pussy with a loud squelch. His half-inflated knot did absolutely nothing to stop him from stuffing the entirety of his cock into the needy bitch, but it did stop him from pulling back out, already swelling to its full size from how incredibly tight Umbra suddenly got. All he could do was remain buried balls-deep, hugging his two favorite pokemon in the whole world as Umbra’s insides coaxed him toward a grand finish. 

“Yes! Finally! Cumming!” Umbra declared mere seconds after penetration, her insides clamping down and releasing just as quickly, each squeeze-unsqueeze causing him to see stars. The umbreon giggled with delight, sounding very much like her younger sister in this pleasured, blissed out state. 

Umbra's song of bliss finally pushed him over the edge. “F-fuck, me too!” he said as the initial squirt escaped him, splattering the umbreon’s cervix with the first of many hot, gooey ropes. “Cum with us, Ollie! Let’s all finish together!”

“Hehe, I’m already cumming, Big Bro!” 

He almost winced at the nickname. Technically, they were honorary siblings, what with him being mated to Umbra and all. But while fucking two sisters was hot as fuck, fucking his own sister would take some getting used to.

More importantly, Ollie was right. She was cumming (again). It wasn’t as obvious as before, with most of his length firmly lodged inside Umbra, but he realized he could feel Ollie’s tiny spade twitch and jerk against his sheath, slathering his crotch in warm, sticky fluids.

“H-hey, stop licking me! Ollie—haha—ewww, nooo, stoooop!”

Blinking in confusion, Nebula leaned even further over Ollie’s back to witness a sight that had him snickering. The eevee was assaulting his mate’s neck with a volley of licks, and given they were chest to chest there was nothing she could do to stop it. 

Even while their spades jerked and flexed against one another, they were still sisters in the end. It was quite adorable how Umbra pretended she didn’t love the affection.

Minutes passed by in a pleasurable haze. Ollie quickly got bored and was now cleaning herself off to the side. Aside from her smaller size, this was another reason he hasn’t knotted her yet. Dealing with a bored, whiny kid was a nightmare in normal situations; being tied to said whiny kid for minutes on end promised to be exponentially more unbearable.

They made out for a bit at first, but they soon transitioned to simply resting their snouts on each other’s backs, snuggling close. 

“I love you,” he whispered into her ear.

“Mhm. You too.” She shuffled, squeezing him particularly hard as her muscles tensed. “You should knot Ollie soon. She’s getting annoying about it.”

He snorted at the suggestion. “I was thinking something similar, but I'm not sure yet. She’d get bored, and I can’t imagine anything more annoying than a bored Ollie whining ‘is it over yet?’ every minute.”

“That’s the point, dummy! She likes all this ‘lovey-dovey’ stuff we do, but being stuck in one place, tied to you for half an hour?  Once she realizes how boring it is she’ll be perfectly content with you pulling out, which is good since we have no idea exactly when her heats will start. Soon, probably.”

“Not a bad idea,” he said, considering his mate’s words. “Though right now I’m perfectly content being tied to you.”

“Sappy bastard,” she growled, the tiny smile on her muzzle betraying her true feelings. “I’m still horny. Make me cum again before our tie ends and I’ll let you knot my ass tomorrow.”

Snuggling closer with a laugh, he reached toward her spade and pressed firmly into it with a paw, making the turgid flesh tense hard. 

Ignoring her adorable squeak, he whispered, “Deal~”
