Utopia’s Natural District is the City’s premier zone for taking in nature’s beauty. Hundreds of acres of land has been preserved for many parks, plazas, and nature preserves. Ornate fountains and statues depicting heroes from the ancient wars and other prominent figures dot the verdant landscape. Miles of paved paths and more rugged dirt trails weave around the area, making it perfect for running, hiking, and biking alike.

Every week on this same day, twin rabbits Rose and Thorn can be found jogging briskly, working their youthful bodies into a healthy sweat. Today, the pair are taking a circuitous route that circles around the outer edge of the section of deeper forest. Being equally used to the exertion, they keep up beside each other at a moderate but steady pace. At the six-mile mark of the ten mile loop, they stop off at a bench to rest a little and rehydrate.

“We’re making good time today!” Thorn says, checking his watch. He takes a seat on the bench, massaging his legs to work out the tired muscles.

“That’s good,” Rose replies as she sits down beside her brother. “I’m glad the weather decided to behave this week. I’ve missed this over the past two weeks of rain.” The girl takes out a bottle of water from the pack around her hips and takes a long swig then replaces the cap with a gasp of air as she catches her breath.

Thorn copies her with his own bottle. “Yeah, it’s a nice day! Haven’t seen Ferdinand and Marjorie around though. Maybe they’re taking it easy this week.” He remarks, naming two classmates from their high school.

“Or they’re around elsewhere,” Rose suggests. “Speaking of Ferdy though…Have you considered his suggestion to join the Track Club?” She looks to her brother with a hopeful smile.

“This again?” Thorn sighs. “You know I hate competition, I just enjoy running for the fun of it. Getting outside, meeting others, the pleasure of good exercise, all that is why I’m out here every week. And hanging out with my sis, of course! Plus it’s a good—”

“—A good way to stay in shape, yes I know,” she finishes for Thorn. “But together we would absolutely rock at Track! You could be enjoying all those things, AND earning yourself some personal glory, and maybe even a scholarship for college.” It’s an argument they’ve had many times since Ferdinand let the siblings know there’s exactly two open spots in the club a month ago.

“Why don’t you go for it yourself then? You’re just as capable of that as I am, I just don’t want to run because I HAVE to, but because I WANT to. Those competitive clubs take themselves way too seriously sometimes. I’m sorry Rose, it wouldn’t feel right for me. You totally should go for it though!” Rose understands Thorn’s reasoning and encouragement, but she’s disappointed all the same. The cubs sit in amiable silence for a few minutes of rest. 

Thorn takes another pull from his water bottle, and stretches deeply, arching his back and extending his legs in his seat, enjoying the pull of his pleasantly sore muscles.

“Oh? Well someone sure is excited,” says Rose, with an audible grin on her lips.

Thorn straightens out and looks around to find whoever she could be talking about. He turns to Rose to ask, and follows her gaze downward to the erect bulge pressing tightly against his snug-fitting training shorts. “Thinking about Marjorie, hmm?” she quips, giving Thorn a sly smile.

“Hey! I most certainly was not!” Thorn responds with indignity in his voice, but he doesn’t bother to cover himself up. After all, they were both intimately familiar with each other’s bodies from growing up in a very sex-positive rabbit household. “It’s from exercise! I can’t help it. All that exertion puts my body into an…energetic state, let’s say.” 

Rose giggles. “Well…I just might know what you mean,” she says.

The cryptic comment stirs Thorn’s curiosity. “Is that so?” Thorn’s mouth curves into a smile. “Are you perhaps feeling a bit warm down there as well?” His eyes dart down to the front of his sister’s cerulean pleated skirt.

“Maaaybe.” Rose slides over closer to Thorn, pressing her side against his. “Aw, but it must be SO uncomfortable for you to have to run in such an “energetic” state, right? Mayhap we help it to go away?” The unmistakable mocking tone of her voice is enough to belie her aforementioned “energetic” condition to Thorn.

“Oh yeah, you’re definitely feeling it.” His voice is a low mutter as Rose nuzzles her head against Thorn’s shoulder. “Uh, we should probably get off the path though. Let’s go into the forest a bit behind some trees, huh?”

“Good idea!” Rose hops up to plant a quick kiss on Thorn’s cheek before rising and taking Thorn by the paw to lead him into the woods.

After a good twenty yards or so, the pair find a small, open patch of thick grass, the paved path behind them obscured fully by trees and bushes. Not wasting time, Rose turns her back to Thorn and reaches underneath her skirt to unbutton her panties from her tail, bending over to pull them down to her footpaws, giving Thorn a full look of her mottled gray-and-white rump and swollen princess parts. She removes the silky garment entirely, and stuffs them into her pack.

“Oh and let’s not forget this,” she says as she removes a small cylindrical object from the pack and presents it to her brother. Thorn identifies it as a discrete lipstick-tube-shaped vibrator.

Thorn is taken aback. “What? Why did you bring that here?”

Rose gives her brother a look of exaggerated derision. “For emergencies like these, of course! A girl has to be prepared, you know. You boys aren’t the only ones afflicted with random bouts of horniness.” Rose sticks her pink tongue out at Thorn, at the last. “I bring it wherever I go!” 

“Well,” she amends herself at her brother’s quirked eyebrow. “I actually have three of them. Online shopping is a wonderful thing!” Quickly moistening the toy with said pink tongue, she clicks it on. It buzzes merrily and she applies it down against her needful sex. The lustful groan she gives makes the boy hyper aware of how tight and confining his shorts are at that moment.

Not having the convenience of easy concealment of a skirt like his sister, he opts to pull his shorts down to mid thigh instead. The smooth, bright red synthetic material of his sport briefs attracts Rose over like a bee to honey. With one paw currently between her own legs, she reaches out with the other to press and knead her fingers against the tight bulge of Thorn’s “thorn.” After a few moments of this amidst the boy’s soft moans, and with no opening in the front of the underwear, she pulls the entire garment to one side, exposing his entire four inches of rabbit cock and white downy-furred pouch. With no hesitation, Rose gets down on her knees with her brother standing before her, moves in with her tongue, giving her brother’s most intimate flesh long licks from base to pointed tip from all sides until properly lubricated with her warm saliva. The siblings huff and moan softly from their own pleasure, and Rose, with both paws (the vibrator toy apparently disappearing up inside the rabbit girl’s body), rubs the shaft and gently fondles the fuzzy sack.

Thorn is in bliss. He pets Rose’s long ears fondly and tweaks the sensitive tips. His cock throbs in his sister’s paw, adding thick beads of his own natural lube to the already slick skin. Before Rose can proceed further, he calls for a halt.

“Rose, Rose, wait, stop a moment. Let’s do it together. I’ll lie down and you can be on top. Then we can both get a taste.” Rose’s eyes shine with the pleasure that one toy must be giving her. The incestrous pair move into position on the ground. The grass is soft and cool against Thorn’s back, feeling quite nice after the run and Rose’s ministrations. Rose herself straddles atop her brother, facing end to end. After some wriggling and shifting to get into a workable position, Thorn makes the first move. He flips up Rose’s skirt onto her back, then buries his lips and tongue into Rose’s “rose”, lapping up his sister’s sweet nectar. Electric pleasure jolts up the girl’s spine, sending chills rippling throughout her slight, young frame. Not wanting to be outdone, she responds in kind, placing her mouth around the tapered tip of Thorn’s shaft and in one slow stroke, taking it into her mouth and throat right down to the base, pressing her nose into the boy’s soft pouch, before sliding back up again to the tip.

The twins continue to pleasure each other in this way. The vibrator inside Rose tickles Thorn’s mouth and tongue, and he alternates between attempting to reach the toy with his tongue, and moving downward to lap and suckle at his sister’s stiff pleasure button. He greatly enjoys how doing the last causes her hips to wriggle against his mouth and rewards him with more of her nectar. Thorn’s legs and bare footpaws, both within Rose’s periphery, twitch and curl as she takes her brother in and out of her mouth. Her tongue traces patterns and roams over the extra sensitive tip. Twenty minutes into the act and their movements lose timing and grow more frantic and desperate.

“Rose! Oh Rose, I’m gonna cum!” The boy announces this between deep licks into Rose’s sodden sex. Thorn is drunk with ecstasy and no longer able to hold back the pressure building inside him, and Rose helps him along that path by furthering her motions upon him. With an unmuffled cry he thrusts his hips upward, feeling with burning lust, gouts of his thick, potent cum flood and cover his cock in his sister’s mouth, before the sucking sensation of her convulsively swallowing all that he has to give her. A high gurgling squeal is the only warning he has before she, like him, hits her peak. Her pussy contracts powerfully, her inner muscles rippling against the boy’s lips, splattering him with her own hot cum. They prolong each other’s orgasms through sustained oral contact, but eventually both cubs wind themselves down. Rose rolls off her brother to his side, both twins gasping in hot, sex-scented lungfuls of air. Rose sits herself up and removes the vibrator from inside herself before the pleasure can turn to discomfort in her oversexed passage and clicks it back off before flopping back down onto her back.

“Three moons Thorn, that was…amazing. That should tide me over for a week!”

“A week? Really?” comes the skeptical reply from the brother.

“Well, maybe a few days. At LEAST.”

The two lie silent for a few minutes, gazing up into the sunset sky above the wide canopy of the forest.

“My face feels sticky,” says Thorn.

Rose rises up to wobbly legs and with one glance of her brother, she’s doubled over herself laughing hysterically. “Ew! You LOOK sticky! I, uh, really got you didn’t I?” She adds, blushing underneath her fur.

“Yeah you really did.” Thorn adds with his own laugh.

“Uh h-here, let me clean that up…” Rose takes the water bottle from her bag. With the water and using her discarded panties as a cloth, she cleans off her cum that was matting his fur and ears.

“Thanks, but aren’t you going to need those?” Thorn asks, pointing to the fully soaked pair of panties.

“No, I wasn’t intending on it. After an…experience like that, it’s best to air myself out…”

The pair set back off down the path they were on, much too worn out to take it at a run after such a vigorous exercise of another kind on this day in the park.
