Doctor’s Visit

Sitting in the back seat, a cap tucked on his head, Marco grinned as he glanced over at his twin sister, Maya's chin laying on her hand as she stared out the window. Though the two rabbits had slightly different shades of fur, with the boy sporting a light grey coat while Maya had a more pale, almost blonde, fur, the two were obviously brother and sister, both slim and tall, with the two both also sharing the same brown hair, Marco's cut into a short and shaggy style while his sister allowed hers to grow out down to her shoulders. Making sure Maya wasn't paying attention to him, the mischievous young bunny slowly reached over to his sibling's little tail, knowing just how tickling and sensitive the cub was down there, grinning as he carefully pinched a single hair between his fingers, plucking it out in one tug as the girl gave a quick squeak, immediately turning her head towards her brother with an annoyed scowl, flicking the boy's cap off of his head, 
"I told you to stop messing with me!" 
"It's your fault, you make it too easy~" 
The mother of the pair gave a sigh as she glanced in the rear view mirror, rolling her eyes as she raised her voice slightly to stop the bickering that was about to ignite once more, 
"Hey, you two, stop it! You be nice to one another, or you can forget all about that ice cream on the way home that I promised, okay?" 
The cubs both grumbled and nodded, getting another sigh from the mom as she shook her head, momentarily regretting her choice of getting a simultaneous doctor's appointment for the two eight year old rabbits. The siblings usually got along just fine, though lately they had both started to get more testy and unruly with one another, going through a slightly rebellious streak, something that their mother was hoping they'd be able to keep down while on their yearly physical with their family doctor. Though a slightly unusual setup, the mom had been able to come to a deal with the doctor to have both twins get their exams at the same time, one after the other, lessening the hassle of having to get two appointments in a row for such a busy clinic, thinking that the siblings were still young enough that they wouldn't get all shy about being undressed in front of one another. Seeing the pair glaring at one another, the rabbit in the front seat took a deep breath, praying that she'd be able to keep the two off of one another's throats for long enough to get the yearly physical out of the way. 

Pulling into the parking lot, the twins hopped out of the car one after the other, still eyeing each other up as they followed their mother into the clinic, ready to retaliate at a moment's notice if the other made any attempt at pranks or other funny business. Walking into the waiting room, the woman motioned for the siblings to take a seat as she went to talk with the receptionists, Marco giving a sly smirk as he noticed his sister sitting opposite from him rather than next to him, having learned her lesson as she crossed her arms with a suspicious glare. Having signed both of her cubs in, the mom was on her way back to join the pair to wait for their appointment when her phone suddenly rang, the twins only getting to hear her side of the conversation as she pulled her phone from her purse, 
"Hey, everything okay there? Yes, it's the… no, the file in the accounts folder, dated from yesterday. What? No, that's not right, it's… okay, hold on, don't touch anything, I'll be right there."
Sighing, she walked over to the two little bunnies, rubbing her temple as she tucked her phone away, 
"Alright, I've gotta head back to the office for a little bit, but… you two can handle it here without me sitting in on the exam, right? You both know the doctor, Darren, and you'll behave, won't you?" 
The two cubs nodded innocently as the woman narrowed her eyes in suspicion, unsure of how much she trusted the pair to act nice with one another without her being there as the referee, but she didn't exactly have much of a choice, not unless she was willing to cancel the appointment and waste most of yet another day sometime later, if the doctor even had another slot open for the rest of the month. Putting her trust on her kids, knowing just how good the family doctor was, the mother gave the twins both a pet on the head before turning to leave, 
"Alright, I should be back by the time you get out. Remember to be nice, or you won't get any treats!" 
Left alone, the siblings immediately turned their eyes to each other, staring down one another as they waited, trying to predict what the other was planning. 

After a few more minutes, the twins saw a familiar wolf dressed in a doctor's coat stepping out from one of the exam rooms, the canine in his early 40s giving a pleasant smile as he waved for the pair to come over, knowing the two well from acting as their primary doctor since their birth, 
"Nice to see you two again, come on in."
The siblings stepped into the office, both taking a seat opposite the padded exam table as Darren stayed standing, a clipboard in the wolf's hands as he adjusted his glasses, 
"Is mom not with you this time around?"
Maya shook her head,
"She had some stuff at work or something, so just us." 
"Well, that's alright. So, who's going first?" 
Both cubs stayed silent as a light blush tinted their cheeks, neither particularly excited about having to get undressed in front of the other, with the doctor chuckling as he put his hands to his hips,
"Come on, let's not get shy here. Alright, Marco, you'll get to go first." 
"A… are you sure, mayb-" 
Maya snickered and shoved her brother forward, 
"Nuh-uh, you first, he said so!" 
Setting down his clipboard, the man patted the exam table, 
"Alright, take off your shirt, drop your pants and hop up here." 
Blushing even harder, trying not to look in his grinning sister's direction, Marco dropped his shorts to reveal a pair of briefs sporting the mascot of his favourite Saturday morning cartoon, the smiling fox plastered on the red underwear making the girl snicker as Marco sat up on the side of the exam table. Darren grabbed the front of the briefs, pulling them down to the sheepish bunny's ankles, 
"These as well, need to get a look at your private bits."
Fighting the urge to cover up his junk with his paws, Marco bit his lip as his dick came into view of both the doctor and his twin, his soft little manhood perched atop a tiny pair of balls, getting another snicker from Maya, 
"Wait, I thought boys were supposed to have a thingie down there, is that it~?" 
"Sh… shut up, dork!" 
Holding up a hand, the smiling canine very gently pinched onto the boy's soft member, gently pulling the foreskin back as he checked the cub's sack with his other hand, cupping the balls as he spoke,
"You shouldn't tease your brother, most boys his age look this small when unstimulated."
Marco gripped the side of the exam table as the doctor pulled his foreskin back all the way, the fondling quickly causing blood to rush to his lower half as he gave a strained, barely audible groan, looking away with a flushed face as his shaft began to stiffen in the man's hand, making his sister raise an eyebrow, 
"Woah, look, he's getting bigger!" 
Darren nodded, 
"As I said, boys tend to get bigger when they're touched down here. It's just a physical reaction, nothing to be ashamed about."
Intrigued by the exam, getting her first good look at a naked boy, Maya leaned over the doctor's shoulder to get a closer peek as he rolled the shaft around in his fingers, taking a good look at it from all sides while gently squeezing at his sack, trying to just make sure the young rabbit was growing as expected, his fondling having the unintended consequence of getting Marco fully hard as the cub whimpered, trying to cover himself up as the doctor had to keep shifting his hands away from covering his crotch. Always happy to educate curious kids, Darren gave the sister a little impromptu anatomy lesson with the help of her brother, pulling back his foreskin while explaining away, Marco's face going bright red as he grit his teeth, unable to pay any attention to the man's speech as he tried to force his erection to go down, 
"This here is the glans, and the hole here is the urethra, you've got one of these as well. It gets hard because of blood rushing in when stimulated, and…" 
With the wolf constantly stroking and squeezing on his sensitive shaft while showing it off to his twin, Marco was unable to do much but endure the humiliation as his sister ogled at his family jewels. 

After what felt like an eternity of the doctor fondling at his manhood, making sure everything was working as intended, the bunny boy finally got to hop off of the exam table and yank his briefs back on, quickly hiding his erection away under his shorts as he blushed with his ears folded by his shoulders, trying not to look his sibling in the eyes. Marco didn't have to linger in his own shame for very long however, since as soon as he was off of the spotlight, it was little Maya's turn for her physical, the girl's smirking and giggling stopping the second she realised that fact as well, her expression dropping as she noticed the doctor looking at her expectantly as he snapped on a fresh pair of rubber gloves, 
"Your turn, little princess!" 
The wolf grabbed the slightly more dainty cub under her armpits to lift her up onto the exam table, laying her down onto it as she gulped, noticing her brother peeking out from behind his shoulder with a wide grin, eager for some payback for her taunting. Darren motioned for the young bunny to drop her pants as he glanced over at his papers, barely even paying attention to the discomfort on her face or the snickering coming from behind him, 
"Alright, probably best if you get those off completely, since you'll need to spread your legs a li'l bit wider than your brother. Oh, and shirt too, of course, as well as your bra, if you're wearing any yet"
Whimpering softly, Maya did as ordered, pushing her pants down and kicking them off as she kept a hand over her crotch, her other arm covering her rather flat chest as she squirmed around, trying her best not to let her twin get a peek at her, feeling awkward with just the man looking him over. Unfortunately for the girl, the doctor wasn't exactly able to perform his exams without first actually taking a look at her bare bits, gently moving her arm out the way of her breasts first. Getting a look at the girl's chest, Marco saw that her tits had only barely begun to grow in, only two tiny buds in place of the breasts he'd expected to see, giving a scoff as he smirked, 
"Wait, aren't girls supposed to like… have the things there? Like what mom has?" 
Gently squeezing the bright red rabbit's chest as she squeaked, checking for any lumps as his fingers massaged her chest, getting her to squirm even harder, Darren chuckled at the boy's question, 
"Girls don't usually begin to really grow their breasts until puberty, which is still a ways away for the two of you, so your sister's size is nothing out of the ordinary."
The doctor's assuring words weren't doing much to alleviate Maya's horror however, unable to decide whether she wanted to cover her eyes or not as she felt her brother's gaze creeping ever downwards, as were the wolf's hands. 

Grabbing the girl's wrist and gently moving her hand out of the way of her crotch, the doctor didn't particularly pay attention to the panties she had on, but that didn't stop her brother from cracking up at the sight of her pretty pink cotton panties, swirls of glitter coming across both sides of the pair as she gave an embarrassed groan and covered her face, trying to push her knees together to hide her lewdness as she felt the man gently pulling her panties downwards. Standing at the foot of the exam table, leaning over it as his eyes narrowed and a big grin spread over his muzzle, Marco watched the canine tugging his twin's panties down, already snickering as she squirmed around on the table, his expression changing slightly as soon as his sister's slit came into view. The boy had a rough idea that girls were different down there, but he hadn't really realised just how different, having last bathed with his mom or his sister back when he was still young enough to not even notice the differences, and not yet having discovered the wonderful world of the Internet. With his amusement turning to genuine interest, the cub leaned over further to get a closer look as Darren gently splayed the whimpering Maya's legs open, slipping her panties further down and leaving them just dangling from one ankle. The wolf noticed Marco's interest, smiling as he prepared for yet another impromptu anatomy lesson, grabbing the girl's loins with both hands and carefully spreading her pussy lips with his thumbs, getting a sheepish moan from her as her blonde fur gave way to her light pink folds, her mound giving a small twitch as her legs flinched and her toes curled up. With his mouth hanging open slightly, Marco shuffled right next to the man as Darren pointed to his sister's slit, the wolf's fingertip brushing up against a little bump near the apex of Maya's mound, getting a squeal from the bunny lying down on the exam table as the doctor chuckled, 
"Sorry about that, should've warned you. This is the clitoris, one of the most sensitive parts of a female's genitals."
Odd feelings began to flit around the boy's chest as he watched his twin's slit getting wet, the wolf's rubbing and probing around getting the girl excited down there, even if she desperately wished that she wasn't, whimpering as a small string of her juices drooled from her pussy lips and leaked onto the exam table. 

Maya managed to whimper and whine her way through her exam, trying not to think about her brother ogling at her privates, and especially not trying to think about the weirdly giddy sensation that that thought brought to her head whenever she did imagine the boy staring at her mound. As soon as the doctor pulled his fingers away from the little rabbit's crotch, the girl quickly sat up and pulled her panties back on, noticing that even Marco was blushing and looking slightly sheepish as she got dressed, not nearly as smug and teasing as she would've expected. Darren snapped his rubber gloves off and tossed them into the trash, scribbling a few more notes down on his clipboard before standing up with a smile, patting both of the bunnies on the back, 
"Alright, you two are good to go, healthy and growing well. That wasn't so bad, was it?" 
Marco rubbed his neck while looking down at the floor, suddenly finding it rather difficult to look his sister in the eye for some reason, a light blush still on his cheeks as he nodded, 
"Y… yeah…" 
Handing the cubs their paperwork, Darren sent the pair out of his office and back into the waiting room, the twins both looking around for any sign of their mother before taking a seat next to one another to wait for her to return from work. The two both had similar thoughts swirling about in their heads, the anatomy lessons with the wolf having awoken a curiosity about the other sex in them both, but more importantly the lessons had awoken an interest in each other. Marco cleared his throat with an awkward cough as he glanced over at his sister, noticing that Maya had been staring at him before quickly looking away the second he turned his head, a silence lingering over the pair before he opened his mouth, 
"You were actually kinda… cute when you… you know… when you didn't have any clothes on…" 
Smiling while looking away, her heart thumping in her chest, the girl took Marco's hand, 
"T… thanks. And… you too. I mean… you were kinda cute too."
With the growing urge to play some more doctor with one another, this time all on their own, the twins sat in silence as they waited for their mother, holding hands as they gave each other shy peeks, unable to hide the smiles on their faces.
