#5 of Entropy Series

Iolvin and Adrian find something to do while the girls are away.

Hey guys, apologies for the silence in the last few weeks. I went to visit my folks and they live in the middle of nowhere, haha. Anyway, I wanted to tell the story of what the boys were up to while the girls were out before I continued the overall story. Also, Delta_Klata, ask and you shall recieve heeeeee.

As always, this story contains mature content and sexual imagery and if you are not of legal age to view it please stop reading here. To everyone else, I hope you enjoy the story!


"I'll take that ride, handsome!" Adrian cheered as he let go of Robyn and latched onto Iolvin instead.

"Alright, alright. My car's right over there, Dee." Yoyo slipped a quick glance at the smiling girls and started to the jeep himself with a grin. "Have fun Lulu, he hushed to himself as he hopped in the driver's seat.

"Lulu... You always call her that."

"Hmm? Sis?" Yoyo quirked back as he started the engine.

"Yeah, am I missing something there? A joke or something?" Dee clarified as he shut his door a second time, not satisfied with the way he lightly clicked it the first time.

"Oh, uh... Well that's her name..." Yoyo put the jeep into gear and started on the way home, buying a bit of time as he handled a turn onto a one-way. "Ilaria's real name is Ielunschra. It's just hard to say so she uses the other one..." He took another moment to pick his words properly as well as get onto the highway. "I just want to keep a bit of my real sister is all."

"I..." Adrian looked out his window a second, then took a gaze at the otter next to him. "I think that's sweet." He slumped sideways against Iolvin's arm briefly, backing off a few seconds later so he could drive. "I didn't take you as the sentimental type, Yoyo."

"I just like my sister for who she is. She shouldn't change or hide anything," Yoyo practically sighed. "You're up a few blocks from us, right?"

"Uh... Yeah. Buuuuuuuut... Could I peep around your place a bit?" Dee lifted up his bag and added, "I've got something I wanna leave for Ari. Err, Lulu. You know what I mean."

"Huh. Not sure I should let your goofy ass snooping around, haha. What's in the bag?"

Dee faked a frown and put the bag down on the floor. "Seeeeeeeecret. Call it an early birthday present, heeeeeeeee."

"And I get to wait for mine. How rude," Yoyo joked as he found their exit and took the offramp. "I can drop it in her room for y--"

"No!" Adrian slumped back and made a fuss about that point. "It's not set up. I barely snuck it out the lab."

Pulling to a stop at a light Yoyo reached over and scruffed Adrian's headfur playfully. "No worries, kiddo. If you want to come over just say so. Contrary to what Lulu's probably told you, I actually like it when you come over."

"Really? Because she's said some things alright, heeeeeee..."

With a ponderous look, and followed with a wide grin, Yoyo added, "Well, maybe not when my parents see you in that swimsuit of yours."

"Gah!.... Meanie!"

The two pulled up the driveway of the Rivet house soon enough, spilling out toward the garage door. They paused for a second as Yoyo fumbled with a key, the side entrance being locked unlike its normal state. They slipped in the door and shut it behind them, Yoyo calling out "Anyone here? Mom?" as he led the way. With no response back he popped into the kitchen, finding a note in his mother's handwriting on the center island.

"Out for dinner and a movie. We'll be out a while, so dinner's on you two." With a sigh Iolvin went back to leading Adrian to the stairs. "And we don't have much in the pantry. Ugh."

"Oh? Well good think I won't be long." Dee peered up the stairs as he took a box from his bag. "Huh, never been up there."

"Right, might as well do whatever you need at my desk. I'd let you in Lulu's room but..." Yoyo gave Dee a smile and started up the stairs. "...well I'm not sure I trust you in my room myself, ya' ditz."

"I'll have you know I work with delicate stuff all day, ya' brute." Dee took a look at he hallway at the top and followed Iolvin to the door at the end. "So stop teasin' me and I might get out your hair faster, okay."

"Alright, hon. I'll stop." Yoyo popped open the door and with his free arm pointed to a desk just to the left of it. "You need any help with that? If we're done soon enough we could hop in the pool or something while the sun's still up. I've got a spare--"

"Ooh, such a big bed!" Jumping so he'd land sideways on the mattress, Dee added, "I've only got a twin at my place."

"Dee, come on. Don't make me think twice about letting you up here..."

"Oooooh, shush. I'm just playing around. Though I have to say..." he propped himself up and wrinkled his nose, a paw slipping across the sheets. "You don't clean up after your 'private time' do you? Seriously, I feel dirty now. Heeeeeeeee."

"Shit... Yeah, I uh... I made a mess and didn't get to wash the sheets." Moving over to pull Adrian to his feet Iolvin mentioned, "Might not want to sit there, in fact. I'll get the sheets while you work on... whatever that is."

"A footpaw. Well, one more like ours than the little carbon fibre blade Ari's using right now." Dee slumped into the desk chair as he watched Yoyo start removing the linens from the bed. "After seeing her pouting on the beach the other day I wanted to sneak this out in advance. That girl must love swimming and it's a shame she can't."

"Well that's awesome, actually. But what do you mean 'sneak'?" Iolvin asked as he finished pulling off the old sheets and went to grab another set to replace them.

"It's tagged as a lab-only item right now. But since there's no pool in our lab that's sort of pointless, so I'm ignoring the rules on this one." Looking at the sheets on the floor, Adrian spotted a jewel of an item and picked it up, then began twirling it around a finger. "So, made that mess alone, did we? Then whose panties are these?"

Freezing in place after making eye contact, Yoyo began running pale beneath his fur for a moment. "I... Uh, that..." He huffed over and snatched the panties from Dee and just about yelled, "J-just forget about it! None of your damn business!"

With a frown Dee drew a long breath and said, "It's alright, sweetie. If you have a secret girlfriend that's your own business. Though you should have invited her to the beach too. I'm sure she's--"

"There's no girlfriend. Alright?" Yoyo held the panties in front of him, for some reason drawn to open them up and take a look. "They're Lulu's. Now drop it."

"Huh?" It took a second for the smaller of the otters to come up with a reasoning of his own. "Oh, so you... get off with her uh...?"

"Dee, seriously..." He noticed a slight bulge in the girly boy's dress, which only brought to attention his own hardening length. With a grumble Yoyo bent over to hide things and started putting the fresh sheets on the bed. "Just... get that thing ready and leave. I need some time right now."

"Hon, ain't nothin' you can do that would freak me out. And I can keep a secret, so don't worry." Putting the box on the table Dee noticed something immediately, that Iolvin's desk was devoid of anything he could use to actually assemble the prosthetic foot. "You have any tools, Yoyo?"

As he finished the sheets sans tucking them in, Iolvin sat on the edge of the bed and thought about the question. "No, but Lulu's got some for her leg. Come on, it'll be easier if you get what you need yourself. I'm no good with that tech stuff." He got up and headed through the hallway again.

Following into the other room of the upstairs of the house, Dee immediately went into a cute overdose when he stepped into Ilaria's room. "Oh. My. Gods. She acts tough but Ari has good taste..."

"Hey, paws to yourself okay?" Car looked about but didn't know where the tools were himself. "Just make it quick. Perfume or something's making me lightheaded."

"Hmm, can't place it but it's nice. I'll have to ask to borrow it, heeeeee." Finding a screwdriver on the floor by the bed, got on his paws and knees to check under the bed itself for more. "I swear, why can't I get a nice bed like this? Mind giving me a paw? Or a flashlight?"

"They under there?" Yoyo asked as he came closer, only to choke on his own tongue when he spotted Dee's dress was hiked up and revealing his true gender quite well. Kneeling next to him to get away from that view, Yoyo found himself in a sticky situation below the belt himself. "Uh, maybe I can reach?"

Dee pressed off his paws so Iolvin could check himself and said, "Sure, handsome. Be my guest."

As he leaned in under Adrian to find the bag of tools himself, Iolvin used his ass to balance himself without thinking. He realized his actions when he came back with the tools and physically saw his paw grabbing a globe of flesh and panties. "I-I... S-sorry!..."

Taking the other paw and pulling it around to mirror the first, Dee hushedly huffed a "No, I'm sorry..." He used the position to line up with Yoyo and let their muzzles meet for a deep kiss. To his surprise however, Yoyo didn't resist. When the slow, drawn out kiss ended Dee could only question, "Yoyo?"

Yoyo didn't give Dee a true answer. Instead he grabbed onto his ass all the tighter and hefted the femboy onto the bed. Before Dee could react, Yoyo was on top of him and pelting him with kisses. Before he could object Dee's dress was over his head and then on the floor. By the time he found the will to question what was happening Yoyo was running kisses down his chest.

"Yoyo... wait..."

"Your fur's so soft... Gods..."

Grabbing an ear to force him to stop, Dee spoke up, "Yoyo, think about this sweetie. Are you sure you're fine with me?"

Iolvin pulled the femboy's panties down to his ankles and just stared at the throbbing cock that bobbed in front of him. "Fine with you? Dee, don't be silly." He practically ripped off his own shirt and added, "I can't stand it. I need you."

Dee smiled and reached down to undo Yoyo's pants, kicking them off with his footpaws. Upon seeing Yoyo's large cock was equally wanting him, he accidentally coughed up, "Shit, giant dicks run in the family or what??"

"Wait... You know about her?" Yoyo stopped everything and tried to get serious, though something compelled him to soften against his will.

"Shh..." Dee reached down and pulled what little of Yoyo's boxer briefs hid his length from sight down, then started stroking that rod of meat slowly. "She showed me. But we'll talk about that later..." With a few tugs he eventually lined his own member with Yoyo's and rubbed them together. "Now... I want you in me, ya' stud."

Iolvin murred as he ground his hips back against Adrian's. "Fuck, me too... But I've, uh..."

"Never done a little thing like me in the ass?" Dee giggled, only to turn serious when he didn't get the intended reaction. "Wait, don't tell me a hunk like you's never had sex at all?"

"Not exactly... No..."

An even larger smile beaming across his face, Dee half-chortled, "Heeeeee, that's sweet. Giving me your first time, silly." Looking about, he then raised the question, "We need lube. It's been a while for me and I'm not trying it dry. There's some in my pur--"

Reaching to the nightstand and back, Yoyo presented the lube he'd handed to Ari the other night. "This do, beautiful?"

"Oh, my favorite brand." The petite otter reached down again with a devilish grin, popping the cap and lathering Iolvin's cock with the stuff. He chucked the bottle to the side and began rubbing his paws up and down Yoyo's length, then momentarily reached to rub his own pucker. "I can take a bit of roughness, but start slow hon."

Stealing that paw back up to coat the other length between them, Yoyo noticed a bit of a difference between them. "You've got a... sheath? Foreskin?"

"Foreskin, dear. Which reminds me..." Dee reached close to Yoyo's base and gave it a squeeze. "You've got a knot, even if it's small. Not too deep too fast, hon."

"Huh? I have one?" He felt around himself and indeed found that he had a knot like his sister, one he never noticed before. But at his age there shouldn't be any additions or changes to that part of him. It's been a decade since he went through puberty. "Uh... News to me, babe. I'll watch it though..."

"Well it's not much for a real girl's bits but for me..." Guiding Yoyo's cock to his little pink flower he finished, "...it's tight enough to matter."

Feeling the warmth on his pointed tip, Iolvin couldn't control himself. He pressed forward rather roughly, popping most of his cock's head into the otter below him in one thrust. It took every fibre of his being to hold back, but hearing a whimper from Dee forced him back to reality. Something was messing with his judgement, driving him to a more primal state. A state that cheered inside him when Dee finally got used to the girth inside him.

"More... Go deeper, hon..."

As he complied with the request, Iolvin growled a deep, "Fuuuuuuck, babe..." He pressed forward, letting himself sink deeper and deeper inch by inch, stopping about halfway into that tight ass of Dee's before there was another hint of pain. "Shit, it's too damn good..."

Knowing he can take more, but still unsure about Iolvin's particular size, Dee wrapped his legs behind Yoyo's back and pulled him in at his own pace. Pulling the heavier otter down for a kiss he whispered, "I want it all, Yoyo." He went in for another, longer kiss and held Yoyo down in an embrace, allowing his own cock to rub between them. "Fuck the knot, I need all of you in me!"

Yoyo growled and softly bit into a pillow, wanting to clamp down on Dee but unable to in their new position due to the height difference. Instead he focused on grinding side to side against his partner's cock, Dee losing the ability to form proper sentences in lieu of pants and moans at the sensations. Then when Yoyo felt his knot finally bump against that hot pucker he simply couldn't resist bucking against it. A few thrusts later, the bulge audibly popped into that tight hole and refused to come free. That didn't stop Iolvin from trying to pump himself in and out of his girly mate, ignoring the winces of pain he let out.

"Shit, Yoyo!--Ah!--Slow downnnnNNnnnn!"

With a long murr, Yoyo pulled back from the pillow and hunched forward for a kiss. "Fuck, I'm..." He started tensing and thrusting much harder now. "I'm gonna cum, babe!"

Without a chance to chip in himself, Dee suddenly felt Yoyo start to throb and grow inside him. Then mere seconds later he could feel surge after surge of heat filling his bowels, a sensation he'd been desperately missing for months now. Yet right when Dee thought he would be left out in the cold, one of Yoyo's paws reached down to jack Dee off. Even as he shuddered from his own orgasm, Yoyo furiously tugged and pumped his lover's cock. And with the wonderful feelings of being so damn full, the blasting heat inside of him, and the rubbing against his prostate, Dee rather suddenly came like a firehose all over himself.

"Hnnnnnnng! Fuuuuck!" Dee writhed below a panting, spent Yoyo right up to the point that he collapsed to hold Dee tightly again. "I-I uh... Nobody's ever... Hng... Ever done that for me before..."

"What?" Yoyo slid sideways a bit as he caught his breath so he wouldn't crush the dainty little otter beneath him. "Nobody's ever helped you out? Well fuck..." He curled up a bit and nuzzled the top of Dees head. "I'll be damned if you're not hitting your peak with me."

The nuzzle was only returned with another and the words, "Thank you, Iolvin." Then once he had a grip on his erratic breathing Dee started tugging on the knot in him to pry it free.

"W-wait, Dee... Don't we need to let it--?" Yoyo cautioned, not wanting to hurt either of them and ruin the moment.

"Nah," Dee let out as he finally managed to dislodge the two of them, "It's not as bad as with women, and your knot's a lot smaller than most furs'."

As lube and cum oozed from where they were joined, Yoyo scooted down the bed so they could just stare into each other's eyes for a few silent minutes. Then when he finally went to speak he only ended up coughing with a laugh. "Sorry, dying of thirst. Maybe I should grab some drin--"

"Nope! I got it, darlin'. Nibbles and uh... Beer? I bet you want an ice cold beer, huh?" Dee sat up and started getting all cheerful again, like a switch was just flipped. Finding his panties rolled up on an ankle, he slipped them back on and got up confirming, "Yeah, I'll go fix something up. We need fuel for round two!"

"Round two...?" As Dee made his way half-naked down the stairs with cum dripping down his thighs the whole way, Iolvin shook his head. "One hell of a day." He took a look at the mess they'd made and decided then, "Gotta clean this up before Lulu's back, too. And the stairs. And the kitchen..." He took a look at the now-vacant hallway and listened to the sounds of a singing, happy Adrian with a slowly forming smile. "Totally worth it."
