Winner’s Round
“Okay,” Dane took a breath as he drew the first card from the stack, “Sixty-nine with Johanna while Gemini licks your balls to further the pleasure,” he could see both girls lick their lips, looking at him hungrily, “Or have anal sex with Johanna, thrusting into her a number of times equal to her age...shoot lovemaking into her, if necessary.  It calls for that explicitly,” he chuckled, noting that his sister’s tail wagged happily as he read it, “Two and a half minutes if this is the first card you drew this round...?”
“There’s two for each player,” Johanna smiled, obviously pleased with both of his options, “If you don’t come on the first one, the second goes on indefinitely until you do.”  She gave her rear a little shake, subtly suggesting which option she hoped he picked.
He hated to disappoint her.  He genuinely did.  It was clear on his face as he said it.  “I’d still prefer us all to be involved...even if I love the other option.”
His sister responded by falling back onto the mattress on her back, spreading the lips of her sex with her fingers in invitation to him, and continuing to wag her tail. Gemini followed, laying herself out beside her bestie, with just enough space left for him to lay between them.  Grateful to see her accept his decision without even a hint of disappointment, Dane determined to reward her with the best muffin-eating she had ever enjoyed.  He laid himself down between them on his side, facing Johanna’s muffin, and took over responsibility for spreading her sex as his tongue dipped deep into her love-tunnel.  It would be easier for all of them to rest their own weight on the mattress.
Between his legs, Johanna hummed with pleasure as she wrapped her lips and tongue around the bone he presented to her, fingertips tracing pleasantly along the insides of his legs.  Gemi curled a little around his rump, lifting one hand to help brace his leg in the air, and used the other to lift his large sac closer to her mouth.  She gave a mischievous glance to the spot beneath his tail, but didn’t want to upset Johanna, so kept her tongue well restricted to her boyfriend’s balls.  They were more than enough to occupy her mouth anyway.  The girls’ noses touched as they licked and sucked and moved back and forth in their respective places, and they openly enjoyed watching each other work him...at least until Johanna closed her eyes, fighting the growing pressure building between her legs.  An involuntary whine began to squeak out of her throat...then her eyes jerked wide as the timer went off.
The Doberman gave her friend a sympathetic kiss on the nose, and patted Dane’s rump firmly.  “How are you still holding it in?” she demanded, tongue lolling from the corner of her mouth and the desire dripping from her vulva dampening his shoulders.  When he didn’t reply, she lifted her head to find his tongue still deep in Johanna’s folds, though holding very still, as though struggling to decide whether to go ahead and finish her or let go.  Johanna had likewise not released his bone from her lips, though her head had stopped bobbing.
Sympathetic to their reluctance, Gemini rolled his balls thoughtfully in her fingers, propping her head up on one hand to watch.  “It’s okay,” she assured them, “I’m no rule lawyer.  Let it all out.”
Johanna opened one eye to look at her, closed it again...and very slowly rolled her hip away from Dane’s mouth while opening hers and carefully removing him.  Then she flopped onto her back, gripping the sheets stretched across the mattresses and panting heavily.  Dane did essentially the same, drawing his knees up and spreading them a little to minimize any sense of pressure.  “I think,” he panted, “At some point...I decided...I want to...see the end...of the game.  Huh...huh...every single...card.”
“Oo,” Gemini groaned, putting a hand to her forehead, “Not if I can help it!  Give me that!”  She rolled to the edge of the mattresses and practically snatched the next card off the top.  “Alright!  I am going to break you both,” she promised, not even reading the options aloud before making her decision...or at all, “Scoot over.”
Dane moved back to give them some space as Gemini took Johanna by one ankle, lifting her leg and rolling her onto her side.  The Doberman then seated herself in the opposite direction, facing the other way, with her legs likewise spread around Johanna.  The Dalmatian recognized what her friend was setting up, and took a similar grip on Gemi’s lifted leg as they scooted closer together.  With a firm pull, Gemini all but mashed their nested muffins together, creating a delicious slurp as the soaking sexes slid against each other.  Johanna moaned aloud, hugging Gemini’s leg against her.
“Mmmhmm,” the Doberman agreed with her face scrunched up in the effort to contain herself, her voice cracking a little in her throat.  After one more deep, labored breath, she waved for Dane to come close again.  “Okay.  Two minutes.  Honeypot, play with your breasts while I grind on you.  Honeybear, you watch while I stroke you.  Go.”  Pulling Johanna’s ankle to keep the pressure firm, Gemi began rocking her hips back and forth, slow and hard, like she was attempting to actually penetrate the other female with her own clit.  The Dalmatians obeyed their respective instructions, Johanna chewing her lip as she began squeezing and rolling her breasts in her hands, and Dane panting as Gemini wrapped her hand around the underside and started pulling as gently as she could manage...an act which was harder than it looked from her position, and it looked hard.
“Mmm!  Ooh!  Oh woah!” Johanna whined with each grinding thrust, her eyes squeezed shut and mouth hanging open.  In the spirit of fair play, she was doing her part to hold the pressure, hugging Gemini’s leg and bucking back against her, until a visible tremble started to run through her legs and she tilted her head back and stopped bucking.  “AhooWOO!” she howled, unable to resist any longer.  The orgasm was so forceful Gemini could feel her expelling more liquid lust onto the Doberman’s muffin like a tiny ejaculation...which, admittedly, surprised even the experienced Gemini.  Gemi was too engrossed in her own efforts and arousal to remark on the experience, though, with her cheek pressed into the sheets and her teeth grit with the effort of keeping up the rhythm and resisting her own orgasm.
“Oh...wuff meeee,” she groaned at last, turning her face down into the mattress to muffle her own howl as she squeezed Dane’s bone (a little uncomfortably) and halted her grind in a sustained pressure against Johanna’s hip.  She was still twitching in the throes of ecstasy when the timer beeped to announce the end of her efforts.  It was understandably ignored for quite a while.
“Now...I think...you are deliberately...trying to...insult me,” she huffed at her boyfriend when she could reliably form words again, giving the bone still in her hand another firm squeeze before she let him go.
“Figured...I’d wait...for my own...card,” he panted back, having clearly avoided his own climax by a very narrow margin.  They all took a moment to catch their breath, none of them much in the mood to move.  After so much time spent fighting the release, finally having it felt extra oozy good, and extra draining.  “Well, I guess the next draw is yours by default,” Gemini remarked, eying the only member of the group who had not reached his peak yet...barely.
“No,” came the surprising counter from the other end of the mattress, “We’ll do them all.  Multiple orgasms.  I’m good for...three?” Johanna insisted, trying to remember exactly how many Gemini had put her through the first time the pair spent an entire night together.
“Ha!” her bestie laughed, scissoring her leg playfully, “I got you to six if I got you even once.”  Taking a deep breath and laying her head back down, she nodded. “Okay.  I’m good.  Let’s do it.”
Johanna, still a little worn out, waved a hand limply toward her brother.  “...Please?”  Taking the hint, he reached over to pull her card for her, then read it when she refused to lift her hand to take it...with an ironic laugh.  “You have to lick and finger Gemini while she fondles her own breasts.  She can hold your hair to keep you between her legs, if she wants.  Or you can rub your clitoris against hers while fondling your own breasts, and I’m supposed to document the event in photograph.”
“Oo, gods forgotten bless whoever wrote that one,” Gemini sighed, practically reading Johanna’s mind and equally grateful not to have to get up yet.  “Set the timer as our break.”
Dane did exactly that, using Johanna’s phone both as the clock and camera.  The girls worked up the effort to lift their heads and spread their legs more fully, letting him get some photos of how they looked when they still had such energy...including sultry looks at the camera and impassioned glances toward each other.  He definitely made sure to capture the noteworthy wet spot in the sheets beneath them as a testament to exactly how much they had enjoyed that release.
“Alright, brother,” Johanna cooed, her legs finally agreeing to work with her again if she needed them to move substantially, “It’s your turn now.”
“Definitely your turn,” Gemini agreed with a lusty look, “No getting out of it.  Second card: you are ours until you are done.”
“I swear to make absolutely no attempt at escape,” he winked, reaching for the first of the last three cards.  “Mmm...it says I have to receive fellatio from Johanna while Gemini films the event, or let Johanna masturbate me until I finish in her hands.  No offense, but I’m about all stroked-out.  Something warm and wet will feel really nice.”
Johanna nodded her understanding, forcing herself upright and scooting her back against the couch.  Instead of kneeling, as she usually did, the Dalmatian simply sat with her knees pulled up and her fingers knit idly between them, waiting for him.  If Gemini felt left out, she didn’t say such as she took the phone from Dane’s hand and nudged him in the direction of his sister.
“Sorry to make you get up again,” Johanna said softly as he took a stance astride her, moving her hands to his thighs and caressing them fondly.
“Wait, wait!” Gemini giggled, hugging herself to Dane’s back and tilting the phone’s camera over his shoulder for a POV shot.  “Okay...now, say that again,” she flicked the little red icon to start recording.
Johanna rolled her eyes, but smiled sweetly up at her brother and the camera, looking bright and cheerful in a way that only these two ever got to see.  “Sorry to make you get up again,” she repeated, then glanced at the rock-hard bone dangling next to her cheek like she’d only just noticed it.  She nudged it with the tip of her nose.  “But it looks like you were already there.  Mmm,” she kissed it tenderly, the hands on his thighs sliding a little higher up and pushing him back about half a step for better spacing.  She licked the dripping tip of him, then glanced up at the camera once more with her tongue still barely poking out, cutely.  “Please...wuff my face, and let me put you to bed,” she said, more softly, and opened her mouth as invitation for him to insert himself.
“Oh, wuff, sis,” he mouthed silently, not wanting to hear his own voice in the recording.  Gemini, likewise, was taking pains to keep her aroused breathing away from the mic as Dane took his bone and laid it on his sister’s tongue, sliding it slowly along into her throat.  She let him get almost all the way to the knot before closing her lips, figuring the camera had gotten enough.  She let him do the moving, keeping her hands idly on his thighs, cooing her approval of his taste and letting him squeeze her ears needily.  “Oh, wuff,” he repeated, audibly this time and increasing the tempo slowly, “Oh, wuff!”
He’d been on the verge since before he got into her, so it was a surprise to no one that he wasn’t lasting long.  Johanna opened her mouth as wide as she possibly could, sliding her hands around behind his thighs to pull him forward more, deeper into her throat, just barely managing to comfortably slip his knot passed the teeth she padded with her lips.  That was the end of him.  He exploded into her, his own mouth open and tongue lolling.  He kept his voice out of his howls, making them sound more like long, wheezing breaths...and if they hadn’t been on film, Gemini would have pinched his tush and reminded him that he was supposed to be loud tonight.
Johanna patted his thighs three times, quick and sharp, trying hard to get a good breath through her scrunched-up nose.  He withdrew as quickly as he realized what he was doing, drawing a trail of his milk down her tongue and laying the next surge right across her nose.  His sister never stopped smiling...but did swallow quickly and take a good, deep breath as he splashed the last few pulses against her face and breasts.
“Are you okay?” he asked quickly, concerned he’d gotten carried away.
Johanna nodded, licking the aftermath from her muzzle.  “Yeah.  The pressure was nice, actually.  Like when you squeezed my muzzle.  If I could breathe, I’d encourage you to hold it.”
Gemini turned off the recording, looking down over her boyfriend’s shoulder.  “Honeypot...are you okay?  I judge no one’s kinks, but if applying pressure to your skull feels good, you might actually want to see a doctor.”
Johanna tapped her chin thoughtfully, and nodded.  “You have a point.  I’ll be sure to ask about it at my appointment.  How was the video?”
“I would pay to watch porn of this quality,” Gemini sighed into Dane’s back, gazing adoringly at the automatically created little thumbnail for the video, “I will never forgive you if you do not send a copy of that to me.”  She handed the phone down to Johanna, to let her see what the experience had been like from her brother’s eyes.  It was short...but very satisfying.
“It’s your turn now, sugarcube,” Johanna sighed quietly.
“Mmm...you can have it,” the Doberman said, resting her cheek against Dane’s huffing back, “I’m still worn out from the last one.  Give me just one more show.”
“It might still involve you,” her friend reminded her, carefully backing up onto the couch and crawling along it to get at the cards without moving the couple.  She read it briefly to herself, and her eyes lit up with subtle delight, before she looked back at Gemini.  “Are you sure you don’t mind?  It’s a good one.”
The Doberman shook her head, smiling in amusement.  “No take backs.  It’d be mean after seeing that look you just made, anyway.”
Johanna nodded, reading the card aloud.   “I am to be rubbed and fingered by brother as deeply as possible...or engage him in tail-sex as slowly as possible while touching myself.”  
Her brother and her best friend both laughed a little breathlessly, having no doubt about which of those options she was taking.  If Dane still had any reservations, they were being taken out of his hands...and he was okay with that.  “I hate to think what I’d owe you if I had taken that back from you,” the Doberman winked, pulling Dane back toward the center of the mattress.
“Get the box, please,” Johanna asked her friend as she, also, crawled back onto the mattress, laying on her side with a happy sigh and relaxing with some deep breaths.
“Box?” Dane arched a brow.  This was the first he’d heard of any box besides the one containing the game.
Gemini slid a small lacquered box into the light from beside the couch, where it had apparently been “hidden” the entire time.  Flipping open the lid, it contained (from what Dane could see): a pair of long silk cords, a padded pair of handcuffs, a feather and eye-mask (he presumed he should interpret that as a blindfold), a modest(?) dildo, what looked like the twin to Johanna’s butt-plug, and a jar of lubricating jelly that occupied nearly a quarter of the box.  It was the very last item that Gemi pulled out before tucking the box back around the couch.  “The other thing, too,” Johanna prompted as Gemini turned back toward them.  The Doberman reached back into the box, under the lube, and fetched a single plastic-wrapped rubber.
His girlfriend giggled at Dane’s look of mild surprise as she got down beside him, as though he should expect this sort of thing by now...which wasn’t inaccurate.  “My ‘Little Box o’ Kinks’,” she explained, “You never know what a party night will need.”
“Uh-huh,” Dane chuckled, accepting her reasoning all too easily, “Well, I’m pretty sure I know what to do with this,” he tapped the condom, “And I’m not complaining.  I’m just curious about why now?  This is the first time you’ve ever suggested there even be one in the house, much less used.  I didn’t think you trusted them.”
“I don’t trust them to prevent my getting pregnant,” she reminded him, “And even then, only because we’re siblings.  You and Gemi should use them, unless she wants to have kids with you.  I have no right to an opinion one way or another there,” she added in matter-of-fact tone, reaching for the lubricant.  Gemi snatched it out of her reach.
“Oh yes you do...but that’s a talk for another day,” the Doberman stuck her tongue out at her friend, opening the jar and scooping a glob of the grease onto her fingers.  “You take care of that,” she nodded at Dane and the condom, “I’m taking care of this,” she patted Johanna’s rear with her clean hand, tail wagging and a sly look in her eyes.
He had grown quite soft since his climax.  But that look in his girlfriend’s eye as she reached for his sister’s tail cured that problem in a blink.  Dane would have no problem fitting the condom now...though it might have some trouble fitting him.  “Yeah,” he sighed, and they couldn’t tell if he was acknowledging her explanation or remarking on the sight before him as Gemini began gently circling Johanna’s tail-hole, spreading the slippery jelly around the rim.  “Uh...but you can’t get pregnant like we do it...so...,” he began unwrapping the stretchy little piece of rubber.
“Mmm,” Johanna nodded as Gemi slipped the first finger into her, “Yes, but...you still have to do Gemi tonight, too...in the muffin...ahn...and that’s not safe, in that order.”  She chewed her lip, tail wagging slowly beside Gemini’s hand as the Doberman worked it back and forth tenderly, gazing down with a lusty look and her tongue poking out the corner of her mouth.
Dane swallowed, rolling the rubber sheath down his own length all the way to the base.  Gathering a little lubricant for himself, he crawled around to lay where he could see her other end while stroking the substance across his own member.  Gemini had already added a second finger...and then a third, as he laid down within view, teasing the area between muffin and rim with her thumb.
“Ookay,” Johanna sighed, looking back at her friend after letting her brother enjoy the view for a few seconds, “Are you prepping me, or wuffing me yourself?”
“Do I get to pick?” Gemini grinned, running her tongue over her lips again and pressing a little further in, insistently, causing Johanna’s mouth to fall open in a silent moan.
“Wuff...come to this end and spit-roast me, then, if that’s what you want,” she sighed, laying her head back down, “That belongs to him.”
Gemini’s eyes lit up for a second, as if that arrangement had just occurred to her, then she shook her head in disappointment, withdrawing her fingers.  “This is supposed to be your finish.  I didn’t bring the strap for the dildo, anyway. But you can bet your sweet button I won’t make that mistake again,” she warned, leaning down to kiss the cheek beside the Dalmatian’s tail before crawling back up near to her face again, where she could watch every bit of emotion that crossed it.
She was understandably surprised to find it...blank.  Or mostly so.  Johanna had lifted her head back up, looking at her friend with that unreadable mix of surprise, curiosity, and apathy that was her daily expression.  “Do you want to see if Ares will bring it over?  It’s not too late, and you don’t live far even on foot.  I’d let you use it later.”
The Doberman almost teared up, but not for the reasons her friend might suspect. “Oh gods forgotten, he said you could switch it on and off, but...Johanna, have you just been acting for us the whole time?”
“Most of it,” the Dalmatian admitted, laying her head back down and closing her eyes, “It’s been a lot of fun, and I’ve enjoyed all of it.  It’s just hard for me to show it without making an effort.  But I’m getting tired now, and I’d like to drop the act...right after this one,” she hiked her hips in Dane’s direction, “So stuff me already.”
Gemini looked genuinely hurt...or like she honestly pitied her friend for the first time in years, and was suddenly uncertain of a great deal of what she had thought were good times they’d had together.  Dane just chuckled and patted her leg.  “She’s like that sometimes,” he said softly, “Surprises me, too.  Okay, sis,” he turned his attention back to the Dog patiently waiting for him to wuff her, “I’m going to satisfy you now.”
“Oh, you do that every day,” she sighed, knitting fingers with the hand he passed under one of her legs to keep it raised and her bottom spread wide.  As he pressed into her, she reached out with the other hand to find Gemini’s, knitting fingers with her as well.  “I love you,” she said to both of them and no one in particular as he slid all the way up to the knot on just the third stroke.  Her brother paused for a few minutes, rocking against her without actually thrusting, while her insides stretched and relaxed in readiness for him.  They’d gotten a good feel for this process over the last few months.
Gripping Gemini’s hand, Johanna promised, “You’re about to see something real.”  Dane rocked forward twice more, gently...then once, firmly.  Johanna’s face scrunched up and she grit her teeth.  “AUugh!..YES!...yes,” she cried as his knot slid through with a slight pop, leaving his sister flushed and panting with relief and desire, “Ho...ho...I like this part.  Being filled with him...bound to him...”  Letting go of his hand, she grabbed the back of Gemi’s head, pulling her friend in for a deep, tongue-rolling kiss...which the Doberman was all too glad to return.
“Wuff, now you’ve gone and got me wet again,” Gemi sighed pleasantly, tongue still lolling as they broke the kiss.
“Good,” Johanna sighed with a sincere smile, “The very last card is yours, and you’ll be reading it very soon.”  While their lips had been locked, her other hand had abandoned Gemi’s to drift between her legs, where it was now running little circles around her pearl while she felt Dane’s knot swelling in her back door.  Her eyes were closed as she concentrated on the motion of her fingers and the rhythm of her breathing...until Gemini laid a finger on her tongue (one not covered in lubricant), caressing it.  Johanna licked the fingertip, kissed it as it returned with a second, and closed her lips around both with a hum, letting the Doberman “penetrate” her from the front.  Each time her brother rocked forward inside her, Gemini also slid down into her muzzle, and the Dalmatian moaned with desire and contentment.
Despite his recent orgasm, Dane finished before his sister, the sensation of him pouring into her driving her over the edge of her own climax.  “Now,” the female Dalmatian told her friend as they began cooling down, “You’ve got about ten minutes, maybe a little less, before he unties with me.  Until then, do anything you like with my body to keep yourself wet.”
Gemini kissed her again, scooted a little lower to kiss her breast, and then lower still to plant a kiss between the glistening folds the Dalmatian held open for her.  “Mm...before I dive into that, let’s see what I’m going to do with whose body for the last card,” she suggested, sitting up and reaching over to pull the last card off the console.  “Hmm...get licked by Johanna as quickly as possible or rubbed and fingered by Johanna as slowly as possible,” she tossed the card aside, sounding a bit disappointed, “Fire that writer.  After the last few turns, that hardly seems like a finisher.”
Johanna nodded her agreement.  “We’ll make our own, then.  It’s going to be rough on brother, though,” she admitted, running her foot along his arm apologetically, as he was still kneeling below her tail waiting for his knot to shrink.
He chuckled breathlessly, giving her hip a pat.  Dane could already guess what his part would be...and three in one night, so close together, would definitely be a trial of his endurance.  Then again, he didn’t actually have to finish a third time...just keep it up long enough to satisfy her.  But he had the distinct impression his girlfriend would not be satisfied if he failed to climax in her.
Gemini could also guess what she was getting at...and how much strain that was going to put on her poor boyfriend.  That he didn’t complain was sweet.  The Doberman crawled back over to give him a brief kiss, then gave the same to Johanna, then surprised them by getting to her feet and heading for the hall.  “I think he’s going to need a break first.  A good one.  So I’m going to get a shower, then let him put me to bed.”
They both seemed to agree that was a good idea, as neither of them objected or proposed alternatives.  So Gemini helped herself to the hottest of the hot water, washing thoroughly and relaxing herself in preparation for one final round.  Compared to what she and Johanna had done on their first night, it had actually been a pretty short party.  And she was comfortable in the certainty that it would leave her much less sore the next morning...but somehow it felt almost as exhausting.  Almost.  She wasn’t too worried about passing out before getting her last treat, at least.
The shampoo was all rinsed out, and she was about to step back out when the frosted glass door slid open and Johanna stepped in, greeting her with a kiss.  “Stay a minute longer,” the Dalmatian asked her.  Gemi smiled and put her arms around her, shamelessly rubbing down her recently released rump...gently.
“Worried I’ll start without you?” the Doberman teased, turning the other female around and offering to shampoo her back.
“Not especially,” Johanna shook her head, “And I wouldn’t complain if you did.  I just wanted to talk for a minute, since I think some things were said and done that you might be worried about.”
“Oh?  Like...?” Gemi asked as her hands made their way lower with the shampoo, and Johanna arched her back to push her hips out.  That area definitely needed thorough cleaning, on both sides, and Gemini was careful to be extra tender and light with the touch.
Johanna shook her hips once, suggestively.  “The spanking was really okay.  I’m sorry I scared you both when I screamed.  You looked like that really bothered you.  Also, although I am tired of the act for one day, I really have enjoyed this whole day with you and brother.  I’d like to do it again, both the day and the night.  So don’t be worried if I let my guard down and go back to deadpan-me.  Dane says ‘the natural me is the best me’, but you see why I don’t entirely believe him.”
“Well, he’s right,” her best friend admitted, turning her around and pushing her back against the wall, “But the natural you is also the you that goes so far as to put on an act all day...and makes it so believable that I can forget what it takes out of you.  You just caught me by surprise.  I’m sorry I worried you.”  She kissed the Dalmatian on the lips again.  “Next time, just stay dead-pan the whole time I’m wuffing you and I won’t get confused,” she concluded with a wink.  “Now, I’m going to dry off, give your brother the best birthday-ride he has ever had, and use you as a full-body pillow to fall asleep with.”
Johanna nodded her understanding.  “I’ll be sure to smell good for you,” the Dalmatian promised, making Gemi giggle before she stepped out of the shower and set in with the hair dryer...
It took nearly an hour for all three of them to cycle through...and Gemini was pretty sure Dane got a cold end to his shower, the poor guy.  By the time he got back to the living room, the girls had pulled the pillows and blankets into a little nest around the perimeter of the mattresses, with them sitting in the center of it, making out casually while they waited for him.  More specifically, Gemini was slowly spreading kisses and the odd lick around Johanna’s throat and face, while Johanna sat with eyes closed and mouth relaxed open, soaking up the affection.  Both of them were keeping their hands to themselves, and in appropriate places, too.
“There’s the birthday boy,” Gemini cooed as he stepped onto the mattresses, freshly cleaned, thoroughly dried, and bordering on fluffy, “Come here.”  She pulled him down into a kiss, sitting him right in the center of the little nest they’d made, and Johanna leaned against his back, pressing her breasts into them and running fingers down his tummy.
“Did...I miss something?” Dane arched a brow as the sudden attention he’d been singled out for, “I thought it was Gemi’s turn for special treatment.”
His girlfriend giggled, straddling his lap and rubbing her nose against his.  “Yeah, we kind of forgot whose special day it was for a minute there.  Sorry about that.  I do want my final round,” she clarified before he could ask the question, planting a quick kiss on his lips to head it off, “But I’ve made you work hard tonight already.  Are you really okay going one more time?  We could always put it off until morning.”
He tipped his head up just enough to kiss her nose briefly.  “I’ll live.  How do you want me?”
“Hard,” she growled aggressively, then giggled, “Oo, and deep.  We’ll give you a soft, warm place to lay while you work, though,” she promised him, rolling onto her side and then onto her back, curling her knees up to her sides.  To Dane’s surprise, she then reached for his sister instead of him, urging the female Dalmatian onto all fours above her and then drawing her down to lay almost flat on top of the Doberman, her knees tucked inside Gemini’s to keep them spread and lifted as they nested their necks together.  Then Gemi gave her boyfriend an inviting look, wiggling her rump (and Johanna’s too) to indicate where he should be positioning himself.
Two tails wagged happily at him as he crawled around behind them.  Two moist muffins kissed one another, waiting for him to break them.  Two lusty looks reached him over Johanna’s shoulder, as though awaiting his decision on which to claim first.  It was a little unfair in that regard.  They both knew full well who was getting the bone in this round...but it seemed to please them to play the game.  It was exactly what Gemini had wished for: both her Dalmatians on top of her, at the same time no less.
“Isn’t it going to be kind of hard for you to finish from here?” he asked, as he lined himself up behind them, noting Gemini’s arms around Johanna’s shoulders.
“Not very,” she promised, “Breathing will be the hardest part, but that’s true every time I have sex.  You just fill me good and full of your knot.  My honeypot’s going to help me, right?”  Johanna answered with a brief kiss on her lips, already squirming one arm between them to get her fingers within reach of her friend’s pearl.
Dane chuckled, hunching over his sister’s hips and hugging both of them as well as he was able.  The Dalmatian slid his re-emerging bone between them, following the warm tunnel their folded legs and paired muffins formed, coating top and bottom slick with their combined juices before angling himself a little lower.  “Here I go,” he warned softly, pressing forward and driving himself down into Gemi’s muffin, faintly feeling Johanna’s fingertips playing around her pearl through the soft, wet walls.  Gemini moaned aloud, laying her head back as Johanna kissed her face and throat.
The squirm of their bodies, the feel of both his lovers underneath him, and the soft sounds of their affection just a little above his ears excited Dane to a full erection in no time.  Johanna sighed as she felt the bulge of his knot begin to slide between the lips of her vulva, slicking itself for the plunge into Gemi.  “Oh, sugarcube, here it comes,” the Dalmatian sighed in warning.
“Eep!  Not quite yet,” her friend squeaked as the thick swell nudged up against her entrance, “Play just a little longer.  I’m not ready, and he’s going to finish in no time once that goes in.”  Both Dalmatians nodded their understanding, and continued to kiss, and coo, and finger, and hump the happy Doberman...who burst out in giggles a moment later, earning arched brows from the siblings.  “I’m sorry!  The thought just crossed my mind that I’ve been the Beast-With-Two-Backs plenty of times, but I wonder what it feels like to wuff it.”
“Mmm...wuffing amazing,” Dane grunted, bumping against her so hard his knot nearly slipped in without trying.  She was definitely warm, wet, and ready.
“Oo, I’m glad to hear it,” the Doberman cooed, snuggling in tight under Johanna with a nod, “Do it.  I’m so ready...”
Needing no further encouragement, Dane plowed into her, feeling her tight entrance stretch around and then swallow him.  Johanna groaned, feeling the press of the swell against her own pearl as Gemi moaned with pleasure.  “Oh yes...oh...YES...more!” the Doberman begged, abandoning kisses for open-mouthed licks to Johanna’s cheeks as the female Dalmatian swapped from circling her pearl to simply pressing well-lubricated fingertips to either side, letting her brother’s thrusts and the roll of his knot make all the motion they needed.  Words failed Gemini a second later, and her moan drew out into a wavering, almost pleading howl.
As the noise abated and her breathing became steadier, Dane braced himself to withdraw.  Unlike his couplings with Johanna, this part of Gemini was both slick and stretched enough to allow him to safely pull out even before his knot had softened.  That would relieve them of some weight, allowing them both to breathe more easily again...or so he had thought.  Feeling him adjust, Gemini reached across Johanna’s back and caught him by the ear, pulling him firmly back down.  She had probably been aiming for the scruff of his neck, but the sort of awkward arrangement had made that too hard to reach.
“Ha!  Like wuff I’m...letting you pull out...now,” she panted, probably wishing her legs weren’t pinned under Johanna’s so she could lock him in a little more comfortably.  “It’s your birthday...you get to...fill me all up...”  Gritting his teeth against the pinch, he rocked firmly back into her to let her know he got the point...at which time she seemed to realize exactly what she’d done and how much it probably hurt.  “Oh!  I’m sorry,” she gasped, instantly letting go of his ear.
He shook the sting out of it as Johanna looked back at him with a vague expression of concern.  “Heh, I’m alright,” he assured them both, “But next time, maybe just ask.  It’s not like I’m going to refuse.”  He patted Johanna’s bottom as he adjusted himself on top of them again.  “You alright, sis?  Too heavy on you?”
“You should be asking the girl on bottom,” she responded, working her arm out from between them to better support him and take some of the burden off Gemini.  “Only problem I have is getting sleepy,” she assured them, nuzzling Gemini’s soft cheek, “This’ll probably be my last hurrah, but I’ll move to the couch if you two want to keep going.”
Dane bucked against them both enough to jostle them on the mattress, causing Gemini to squeal and latch onto Johanna, who moaned at the renewed pressure on her pearl and braced her arms in preparation for another one.  But her brother was just giving them both a little boost in alertness, and chuckled as he resumed rolling his girlfriend’s muffin.  He exchanged his hug around their hips for a grip on Johanna’s shoulders, pulling her back as he plunged in for extra force.  Dane had learned some time ago that Gemi’s tolerance for pounding was...considerable.  The Doberman only gasped, happily, and wagged her tail at each deep drive...until Dane finally climaxed for the third time in as many hours.  He rolled to the side while still pulsing, dragging both girls onto their sides with him, and they all breathed a relieved sigh as the shifted weight freed their lungs.  Johanna kept one leg high so as not to add undue pressure on her brother, still knotted with Gemini between her legs...and Dane took the opportunity to run his hand up the back of said leg, whisper a compliment in her ear, and kiss her cheek.
“No fair sweet-talking the other girl while I’m still milking you,” Gemi giggled, nesting her neck with Johanna’s for a quick kiss with Dane, giving him silent permission to finally pull out.  The Dalmatian did so with a grunt, and they all rolled onto their backs and lay there just breathing for a few minutes.  “I have not been this satisfied since...well, since you knocked me out mid-orgasm, honeypot,” Gemini chuckled.  When she got no answer back, she glanced over at the Dalmatian lying between her and her boyfriend...and found her with eyes closed and breathing slowed to the long, deep draws of sleep.
With a chuckle, Dane crawled over his sister, settling between the girls as Gemi pulled a blanket from the nest over all three of them, then curled up in his arms with her back spooned against his stomach.  They didn’t even bother saying good night.  It had been the best night.
Gemini was just on the verge of sleep when Dane lifted his muzzle next to her ear.  “By the way, sweetness...just how much does your brother know about...us?”
Her ear perked curiously.  “Did he say something?”
“Not outright,” Dane admitted, “But he implied it, and I just want to be sure I’m not jumping the gun and misinterpreting.”
The Doberman nodded, understanding his worry, though she thought it was misplaced where her brother was concerned.  “Obviously, he knows you and I are wuffing.  Pretty sure I’ve gushed about my nights with Johanna, too...but he knows we dated, so that shouldn’t surprise him.  I swear I have not let on that you and Johanna are also a thing...but my brother’s no fool, so it’s not impossible he’s caught on.”
Dane sighed deeply, uncertain how comfortable he was with that.  It was one thing to push the boundaries in a big city where they weren’t known to anyone.  It was another entirely to let word get out around home.  But he didn’t want to offend Gemini by suggesting he might not trust her brother.
“If he brings it up again,” his girlfriend continued sleepily, “Tell him to go kiss a dog, and he’ll leave you alone.”
That...surprised him.  “Kiss a dog?” Dane quirked a brow, pressing his cold nose against her cheek to keep her from falling asleep before explaining.
Gemini giggled.  “Sibling inside joke.  He’ll know what it means.  And he won’t give you anymore grief.  If he does, just tell me.  Now,” she rolled over to kiss his lips, then each of his eyes, forcing him to close them, “Good night.”
