#9 of Entropy Series

A fun morning checkup ends with some unexpected actions.

Hey guys! Back again with the group! I'll warn right now that this one ends on a cliffhanger, but don't worry as I'm already workin on the next part of the story. I just thought it would be better to split what was otherwise going to be a massive entry into two smaller parts.

As always, this story contains adult content and sexual themes and if you aren't of legal age in your area to view suck material you should stop reading now. To everyone else, enjoy the story! Comments and critiques are welcome! <3


"Ah, she lives." Iolvin put his jeep in park in the driveway of their house and undid his seatbelt, just sitting there for a moment when a bit of chest pain caught his breath. "Gah... Good to see you back in action, sis."

"Back in...?" Ilaria too tried to move about and brought the puncture in her chest to the forefront of her mind. "The fuck?!" She leaned back and put a paw between her breasts. "Gods, it didn't hurt like this going in..."

"You were awake for that? Damn, Lulu..." Yoyo exited the vehicle trying not to bend his upper torso and then made his way around to help his sister. "I don't remember any of that. How bad was it?"

"I only remember bits. It hurt, lots. I do remember feeling pretty good at one point though." Ilaria undid her seatbelt and slid off her seat with the help of Yoyo's arms. Spotting a hint of gold in the sky Ari added, "Good thing's we're still up and about. How long were we out?"

"The girls said it was over three hours in... And I waited about another hour for the drugs to wear off so I could drive." Yoyo locked shoulders with his twin and helped her walk, the drugs still having an effect oh her and compounding her pre-existing walking issues.

"Wait, it was that long? What about Robyn?"

"Dee talked to her. She thinks you turned ill and went to the hospital." Yoyo hit the door and fumbled with the keys in his one free paw. "Not sure about the details, but she was gonna meet you later to check up."

Ari shifted her weight off her brother so he could properly open the side door, immediately taken back and having to latch onto him to keep from falling when she saw what was on the other side. "AH! Hey Robby!" she burst out suddenly as Yoyo tugged her through the portal.

Turning to face the familiar voice, Robyn sat nearly contorted backwards on the living room couch with tears rolling down her face. "Ottah?!" She scrambled to her hindpaws and ran to embrace her lover crying, "I'm so happy you're okay! Wait, you're okay aren't you?!"

"Woah, woah!" Ari winced as the squirrel's head planted firmly in her aching bosom, shaking it off by placing a paw on her head and stroking her headfur. "I think I'll be alright, hon. It's not a hundred percent, but it's hopeful."

"Hopeful? What's wrong? Oh gods, it's not cancer is it?!" The squirrel looked up with glossed over eyes as she sobbed in anticipation.

"Hon... No, it's not that..." Ilaria fumbled with her lips trying to find an explanation but not wanting to lie either. "I had a hormone problem so they did a quick procedure and if it takes I'll be good. Just no way of knowing until then."

"So... you're not dying...?" Robyn dropped her head yet again in a painful way and extrapolated the ache with a tight squeeze of her arms. "Gods, it's not the same going through Dee... I love you, Ottah."

"Heee, I'm glad he called you like I asked at least." Ari let Yoyo slip away to inform their mother with a similar stretched truth. "I love you too, squirrely-girl. Just... try to keep that hush-hush around the parents for now, alright? They don't know I'm bi quite yet."

"Aww, well that makes dinner awkward..." Robyn tried to slip in a kiss, but sadly was unable to find an opening now that Ari's mother was staring at them. "You should tell them sooner than later, Ari. I mean, when you're ready that is."

"Yeah... We'll see." Ilaria pulled Robyn to her side and nudged her muzzle to the couch. "Gimme a paw? I'm still a bit lightheaded."

Robyn did just that, pressing against Ari's right side to take some weight off her prosthetic. "Here, hon. Just take it easy until dinner, okay?"

"Dear, are you sure everything's good? You look pale," Mrs. Rihzyet spoke up as she headed to the sofa.

"Yeah, Mom. Just worn out." Ari felt Robyn plop down next to her and instinctually leaned against her so they bumped arms. "You know how waiting rooms are..."

"Okay, just don't stress yourself honey. Dinner will be ready soon, and you're not skipping out this time missy." Mom nudged her head over to Robyn and explained, "Robyn's been worried sick about you so we're having her for supper."

"Got it, Mom. Just wake me when you start serving. I'm gonna try to sneak a quick nap in so I'm not grumpy later."

"Just rest up, dear. So Robyn, let's make dessert. What are you up for?"

"Oh, my choice, yeah?" Robyn gave Ari a quick smile and a pat on the head as she got up to follow her mother to the kitchen. "Ooh, my mom taught me how to make the best pecan pie..."

Gently falling into place next to Ilaria, Iolvin leaned against his twin and she did the same. "Mind if I join you? I'm drained too."

"Not at all, Yoyo." Ari put her arms around her brother's shoulder and chest and drifted off to sleep muttering, "...safe with you..."

Yoyo pulled Ari's head to rest on his shoulder rather than roll forward, then rested his head against hers. "Silly Lulu."


A bit of shuffling resounded, albeit as a muffled hint of its former self, up from the kitchen. Suddenly a louder mechanical note entered the mix, Mr. Rihzhet grinding the beans for the morning coffee. An odd beep filtered in through the rest of the morning routine that caught the attention of the two girls, very feminine and somewhat loud voices following soon thereafter.

"So much for our quiet morning, haha!" Robyn giggled playfully as she rocked her hips over her lover's lap.

The squirrel's laughter being muffled in Ilaria's chest only tickled her the right way, the otter pulling the two of them together in a tight embrace. "Ah, shit. I'm think I'm getting close, Robby." She thrust faster and harder against her mate's own motions, Ari's cock throbbing and expanding in imminent release. "Damn I wanna knot you right now..."

Robyn reached down and pulled Ari's member free of her confines, rapidly rubbing that paw along her length with a smirk. "Cum for me, babe. Let it aaaaall out." She sat up and spun around, working both paws with that large dick pointed right at her face. "Don't hold back, Ottah. I wanna see how you cum."

"Ah! Fuck, you an' me both girl..." Ari reached up over her breasts at the tiny, cute ass perched on top of them. She spread the squirrel's rump and got herself a fine view of her pucker and tight pussy. "You're cumming with me, hon." She slid one paw down to press two fingers into Robyn's petals, wriggling and pumping quickly once they were drenched in her nectar. The other went lower to her clit and rolled it about between her fingers.

Losing her concentration due to the sudden bombardment of sensation, Robyn lightly bit her arm to stifle a moan and ended up slamming her paws straight down. "Shiiiit..." In her loss of balance Robyn gripped harder onto whatever she could grab, which at the moment was a large, fleshy knot. "I'm close, babe!"

"Sh--Cummhnngg! Grah!" Ari tensed up, raising her hips as if thrusting into something warm and wet. She shot long, full ropes of seed, and simultaneously loosed a spattering spray of femcum from her cunny.

With a large smile, Robyn pointed Ari's cock directly at her face and shushed out, "Ooh, amazing!" Only the reason she was so locked in thought was because Ilaria was blasting into the tip of a horse-size condom. As the tip filled and expanded, she had to pull it off bit by bit to make room for the excessive load. Eventually she was left with a panting girl beneath her, softening flesh in her one paw, and a cantaloupe-sized balloon of liquid Ilaria.

"Ah, damn... that was--"

"Oh no you don't. My turn!" Robyn sat back so her puss pressed lightly into Ari's muzzle, tying a knot in the condom as she adjusted her position. "I'l so damn close, babe..."

Ari didn't even think twice, lapping at her lover's pink nub the moment it contacted her. She tried to get a fix on what felt best, eventually settling on suckling Robyn's clit while swirling her tongue randomly over and around it. Within moments all Robyn could do was huff and squeak, her hips taking over as her peak struck her like lightning. Her back arched one way then the other, her fluffy tail almost mirroring those motions. By time things were finished, the squirrel found herself face-down in Ilaria's crotch while riding out a few final twitches.

"Hmmhmmmmmm" Robyn chuckled as she righted herself with the loosest of motions. "Now that's how you wake up in the morning."

"Hey... you started it..." Ari playfully groaned out with a weak smile. "Now come... give me... a... kiss..."

Robyn sighed and rolled her eyes as the otter drifted back to sleep in her arms. She gave a soft kiss regardless mumbling, "Silly girl. Pushing yourself for me..."

»Knock knock!«

"Hmm?" Robyn looked at her slumbering lady and then to her clothes across the room. "Uh, one minu--!"

The door creaked open and a light-furred otter leaned in through the door. "Hey, you awake yet Ar--?" The figure popped the door shut quickly with a "Sorry!" and put his back against the door. "I didn't realize you were... I mean..."

Shaking her head at the girly-boy's intrusion Robyn stood up, walked over to the door, and opened it such that only the intruder would see inside. "Dee, I don't mind. What's got you here this... uh..." Once her eyes settled from the darkness Robyn's tune suddenly changed. "Who the fuck are you?!"

Ellie grinned as the squirrel attempted to cover herself with merely her paws. "I'm so sorry to intrude, honey. I'm Ellie, Dee's sister..." He offered a paw but soon found himself lingering in front of a perplexed fur. "Ah, right... Sorry, I can bug Ari in a bit after you two are more... presentable."

"R-Robyn..." The girl hid herself behind the door, her senses returning to her. "Why do you need Ari?" she asked, shutting the door a bit when she spotted a set of eyes peeking at the other fur sprawled over the bed.

"Oh, so you're Robyn! Splendid!" Ellie stepped back a bit and gave up on his snooping and put a slightly more serious look over his face. "I was hoping Ari'd be alone. Need a few samples from her to see how she's doing."

"Samples?" Robyn furled her eyebrows and leaned around the door a bit, spotting a leather bag in the otter's paw. "And you have to get them while we're naked? Can't you just wait until later?"

"Nope, can't wait. I'm on call at the hospital starting noon." Ellie lifted up her bag and smiled. "Besides, one of the samples sort of does require she be naked, hee heeeeee..."

"Wait, the hell does that even mean?"

"I just need a bit of blood and a sperm sample, hon. Following up from yesterday." Ellie looked down as Robyn lost her sense of modesty in thought and let a breast slip around the edge of the door. "I'll uh... I'll need another batch tomorrow too I think... Hey, I can remove that mole for you if you want."

Robyn looked down to see what he was talking about and scrambled to hide herself again. "Birth mark... And no, I'm not letting a stranger get THAT from my girl..."

In a much more serious tone Ellie stated, "I'm sorry, Robyn. I'm just being thorough is all." He leaned in closer and whispered, understanding by robyn's body language that their relationship is hush hush. "Look, I'm sure you guys are in love and all, and it would be irresponsible of me to not make sure you two could have pups if you wanted. I mean, with her physiology it deserves a check. I'll let you gather the one sam--"

Robyn slinked behind the door a moment only to swing it wide open with, "Just get her blood. I've got a sperm sample already." She stepped carefully behind the bed and over to her side from before.

"Ooh, nice ass girl!" Ellie slipped over to Ari and tried rousing her, eventually settling on pulling her arm over while she slept. "She normally a heavy sleeper?"

Rather grumpily covering her lower half in the sheets, Robyn reached around and found her target underneath. "Yeah, since we were kids. And I'd appreciate it if you'd leave my ass out of this. You're only in here because of her."

"My bad, hon. I just meant you shouldn't be ashamed of yourself. Hell, I wish I had a body like yours." Ellie stuck a needle in Ari's arm and readied a phial for extraction.

"Well... Thanks, I guess." Robyn dropped the sheets and leaned over to watch Ellie replace the phial with a fresh one. "Need a lot, huh?" When the second was filled and the line pulled, Robyn went to do some pulling herself on Ellie's shirt. "You have a great body, silly. I wish I had abs like those."

"And I'd give anything to have curves like yours, hon." He pulled his shirt down and took in a great view of the squirrel as she leaned across the bed. "Wow... Seriously, you're a sexy little thing."

Robyn noticed a slight bulge in Elliot's pants and pulled back a bit. "Wait, I thought you were into guys! Shit!"

"Sometimes, if I'm in a rare mood. But mostly..." He flaunted the text on the front of his tight tee shirt that read 'LESBIAN' in rainbow letters. "Don't worry, Robyn. You're safe. I mean, you're hot and all, but we just met and you're in love..." He spotted the blob in Robyn's paws and nodded to it. "Is that the uh...?"

Robyn looked in her paws and frowned in confusion, the condom dimly glowing an amber-orange color. "The fuck?!" she shouted as she tossed the condom into the air.

"Uh, not sure myself..." the otter mumbled as he caught the balloon of glowing jizz with one paw and stared into it. "I'll definitely need to check it out..."

"Maybe..." Robyn looked over to Ilaria's cock which was still dribbling pre, noticing the trail of light going down to her still-inflated knot. "Maybe she's still got that isotope ink stuff in her? She got scans yesterday, right?"

"Y-yeah..." Ellie didn't like stretching the truth about a patient, but respected Ari's wishes anyway. "We did some tests, and she'll exhibit some stuff like this for a bit..."

Robyn nodded and then looked to the otter's bag. "You've got all you need? I'd like to get dressed and grab some breakfast for us."

"Oh, yeah," Ellie jerked out as he forced his eyes away from Ari's junk. "I'll get out your fur. Dee's down the hall so I'll go bug him, hee heeeee."

"Thanks. For Ari, too." Robyn watched as Ellie started back to the hallway then leaned in to give Ari another kiss.

Ellie quietly left the room, giggling a little when he went to close the door and spotted Robyn licking Ari's member clean. He clicked the door shut silently and looked over his samples, the filled rubber at first being the whole of his attention. Then he noticed the blood samples were faintly humming with light as well and he perked his head sideways. Ellie stashed the blood in his bag and gave a quick knock on the other door upstairs.

Opening the door suddenly to another spectacle Ellie said, "Hey Dee Dee, you need to take a--" The otter stopped short when he and Iolvin locked stares at each other, the larger of the two sitting legs wide on his bed with Dee pawing him off from his knees. "Ooh, can I waaaatch?"

"Ellie..." Yoyo tried to make sense of things while he sat there naked as the day he was born and being serviced for all to see. "C-close the door!"

"Ugh, gods..." Dee slowly stroked up and down his man's length with a very leisurely grip. "I think I... need a... break..."

Yoyo pulled Dee's paw away and wrapped his own around his condom-covered meat. "You were up all night, weren't you? No need to worry about me, babe..." He started stroking himself in just the right ways, knowing how to finish himself off quickly. "See, I'm j-just... Ah!, fuck!..."

Ellie slipped next to Yoyo and pulled out a fresh set of lines and phials, partway becoming distracted as he watched the larger otter slowly pulse brilliant fuchsia cum into that latex wrapper over his cock. "Uh, sorry to spoil that but this'll prick a little."

"Guuuuhh...fuuuuuc--OW!" Yoyo flinched and let go of the rubber when he was stabbed by the needle, the weight of the condom's reservoir end pulling the whole thing free of his member and onto the bed. "Shit." He snatched up the jizz sack and tied it up, only now noticing the color of the spilled goo on his paws. "The hell is this?"

"I was hoping Dee Dee would clear that up. I'm clueless." Ellie swapped phials and then leaned over his sister. "Dee Dee?" Finishing the second phial, Elliot pulled everything free of Yoyo and moved to check his sister's condition. "Adrian?"

"How much blood did he lose the other day?" Yoyo asked as he gave his little otter a shove or two.

"Not that much. And I don't think he's allergic to anything we gave him..." Ellie went to check his sister's paw, unwrapping the wound carefully. "Wait, this looks... great?"

"Isn't that a good thing? The sutures doing well?"

"No, I mean... This is almost like a week's worth of healing, maybe more. Gods, at this rate there won't even be a scar by a week or two from now." Ellie wrapped his sister's paw back up and then reached for a fresh arterial tap. He stuck it in and popped a phial on the end, recoiling when the blood glowed a brilliant lime green. "Okay, we have a problem."

"Wait, how the fuck is that happening to him?" Iolvin suddenly gained a sour look to his face and stared at Ellie. "Please say this isn't happening. Isn't he too small for these things?"

Giving his sister a hard slap, Ellie looked back up with a similar expression. "Yeah, that's sort of what he said." He reached for Dee's neck to grab his pulse, then immediately jumped back and reached in his purse. "Shit, this is serious. Can you drive?"

"Drive? What, you thinking hospital?"

"Maybe..." Ellie popped back in place with what looked like a large marker and popped both end caps off. He then jabbed it into Adrian's thigh and tapped a button on the top end. "This epi pen should keep him going long enough. Let's get him to--"

"GAH!" Dee sprang awake seconds after the artificial adrenaline hit his blood. "Shit, what was that?!" He immediately stopped and held his chest, his heart beating bizarrely fast. "That your damn allergy pen?"

"Adrian, listen. You've got those critters in you somehow." Ellie held out the green phial and added, "And you're slipping away fast. Tell us what to do."

"Is that my...?" Dee stared at his blood and then perked back to attention. "Right... We need to find a way to power these things..." He stared at the other colored samples a bit and then went back to his. "Fuck... You're not gonna like this."

"What? I'm not joking. That epinephrine isn't gonna last more than half an hour." Elliot stood up and motioned for Yoyo to help pick Dee up off the edge of the bed.

Watching Yoyo slip some pants on quickly, Dee explained, "We've got a biochemical battery for stuff like artificial heart valves. Thing is, I need a surgeon..."

"Well shit..."

Yoyo slipped into a shirt and bent over to pick Dee up to his feet. "What's wrong? You're a surgeon, right?" He started moving the two towards the door and waited as Ellie picked up his samples and stuffed them into his bag.

"Uh, not for that sort of stuff. I do spinal work." He finally snatched up the condoms and tried hiding them behind his back until the three cleared the door outside. "I'll have to do though. What we did yesterday wasn't exactly legal."

As the group headed down the stairs the twins' parents briefly questioned where they were headed so early, to which the response was fairly vague due to the group's brisk pace. Mrs. Rihzyet started to question further but the three were saved by Ellie's playful smile and her 'water balloons' he was carrying. They all hobbled into Yoyo's jeep and floored it to the lab, spending longer than they wanted locked up in traffic but making it there all the same.

"Uh, that metal table!" Ellie scrambled for supplies he'd need and gathered them on a stainless steel tray. "Adrian, you still with us? I need you to show yoyo where that doodad is, okay sis?"

"I'm... uh..." Dee paused as his mind lapsed while he figured out how best to clamber atop the lab table. "Right, uh... medical... prosthetics... auxiliary systems..." He pointed over to a shelf against the far wall and demanded, "Grab anything uh... with 'BE-BC-PP' on the label."

Yoyo sped over to the wall and crammed anything he could find into his arms that matched the description. "Stay with me, babe! Sing me a song or something!"

"No, ignore that," Ellie told his sister as he came back. "You need to slow your breathing and..." He set the knockout combo of custom painkillers and nitrous oxide on the table and prepped them for use. "Well, I just hope you don't remember any of this."

"Lulu didn't when she came to." Yoyo placed all the various boxes and baggies he'd gathered on the table, about half of which were not related to the procedure but grabbed out of haste. "But she remembered the pain, supposedly."

"Screw it..." Adrian looked through the stack of gadgets and grabbed two boxes. "Process and stuff... all on... inside..."

"Crap. Yoyo, hit him with that gas. I'm gonna clean up and jump in there." Elliot took the tray of tools over to a bunsen burner and got to work sanitizing them. "I hope you're good with diagrams, because you're helping with the manual too."

Iolvin did as he was told and placed the nozzle for the nitrous over Dee's muzzle. "Just hold on, Adrian. You'll make it through this."

As he slowly drifted into a chemically-induced slumber, Adrian whimpered out a most caring, "Love...you..."
