As the setting sun cast the house in deep orange, Katie and Candace peered into their daughter's bedroom. Unlike Kacey's fellow teen friends, her parents were more practiced in the art of stealth  as Candace played look-out while katie tip-toed in as silently as she could. The five-foot tall blue bunny was quiet as a shadow, sneaking towards the bed where Kacey and Shar lay in blissful afterglow. Their hybrid daughter was fast asleep, her monochrome hair still a little damp after the shower with her girlfriend and a cute little grin on her muzzle as she lay in deep sleep. Shar had her eyes closed but katie could see the Labrador's paw tenderly petting Kacey's hair.
Moving behind her, Katie gave Shar's ear a gentle tap with a digit. Shar was quite considerate; even surprised she kept from jumping in surprise and bit back her yelp so Kacey wouldn't be disturbed. Her shoulder-length bronze hair whipped as she turned her head in surprise, however, a protective furrow on her brow until she saw who had disturbed her.
"Mrs. Ka-" she whispered but stopped when Katie placed a digit to her lips and made a little shushing gesture. Shar nodded and looked past Katie at Candace, earning a wave from the panda. Katie nodded her head towards the door and retreated, crooking a digit to gesture Shar to follow without disturbing her girlfriend. It took a little time to do so. Shar was quite tall herself and it took much slow movements before she was off the bed and tip-toing out the door to leave Kacey to slumber peacefully.
Once the door was shut and the totally nude trio were a decent distance down the hall, Katie gave a little sigh of relief. "Whew, that's better. You can talk now, just keep your voice lower than normal, dear."
"W-Won't she hear? I mean, I know she's a deep sleeper and... uh..." Shar blushed after accidentially admitting she'd slept with Candace and Katie's daughter at least once before. The couple giggled and waved the thought aside.
"No worries," Candace assured Shar, the panda almost eye level with the Labrador. "We made sure every room is individually soundproofed. It doesn't totally mute our activities but it's enough to keep from waking anyone."
"That's... really smart," Shar marveled.
Katie giggled. "Care for some tea, dear?"
Minutes later Shar was sitting with her girlfriend's parents over tea in the living room again, this time with zero clothes between them. Save for the white collar around Shar's neck, that is.
"You enjoy wearing a collar, hun?" Katie asked kindly, sipping her tea. "You didn't have one on before so I wasn't sure if that was something you liked. Not everyone has a thing for collars, after all."
In truth, Shar had forgotten about it. Perhaps because it felt so natural? "I, uh... I do like it," she admitted, blushing and looking down at her cup. "It's kinda... something I'm into. Well, I've fantasized at least, I just... never got to try before today."
Candace smiled warmly. "How was it?"
Shar couldn't stop the smile merging with her blush. "It was amazing! My tail wouldn't stop wagging, I felt so happy to be like that and to make Kacey feel so good too..." She sniffled softly and smiled again. "It's the best I've felt in a long time."
The couple smiled at each other and then at Shar. "You're learning more about yourself, sweetie," Katie said softly as both she and her mate walked to sit on either side of Shar on the couch, Candace's  heavy black sheath and Katie's miniature boi package wiggling as they moved. "Collars can mean a lot to the right people. Candace and I, we have special collars. Both have both our names on them, a symbol of how we belong to each other. Belong with each other. <3"
Shar's eyes went wide in awe. "That's so beautiful," she whispered, one paw over her heart. "Oh, Mrs. Katie, Mrs. Candace... I-I hope I'm not being to forward but... I would love something like that. SOmething like that between Kacey and I."
Candace put an arm around Shar's shoulders and gave a little hug. "You will, hun," she promised. "If you two are anything like us, you certainly will be. <3" Katie put her arms around the trans Labrador and the three hugged tight on the couch for a long moment before parting.
"Now, I hope you don't mind us being too forward, dear," Katie said and leaned a bit closer, one paw gently moving along Shar's inner thigh. "But we'd like to give you a little gift for making our daughter so happy."
"O-Oh? Wh-What do you mean...?" Shar managed to ask as Candace's own paws moved a bit south, one strong paw gently cupping a breast.
"Well," the panda purred softly in her ear. "The only room that we can't soundproof is the bathroom, no point really. And during our own cooldown period we heard just how much fun you two were having. So," she paused to give one of Shar's sensitive nipples a little rub, eliciting a whimper, "... we'd like to have a little fun with you ourselves. It's been a while since I've been with anyone my height or size, not that I don't love my little bun-buns. It's just that I don't want to miss such an opprtunity, you know?"
"R-R-Really?" Shar stammmered, blushing hotly again and letting out a little yelp, looking down to see katie leaning over her lap, that little bunny's soft tongue teasing the opening of her swelling sheath. "Ah! Th-That's s-sensiti... haahh...!"
Her cock started to poke out before she knew it, Katie's hot little muzzle ready to tend to the black length as it emerged, one paw lovingly cupping and stroking her heavy golden orbs. Candace was gentle as well but clearly in control as she cupp Shar's chin in her free paw and guided her head up, looking into the Labrador's eyes and smiling. Without a word, the panda kissed her, softly at first and then with more passion. Goodness, but Candace had a long tongue! The three were like that for a while, Shar sitting upright, helpless as Candace kissed her and teased her super-sensitive nipples while Katie's head bobbed in her lap, that expert tongue swirling and teasing her so wonderfully.
"Mm!" Shar whimpered out of nowhere and held onto the couch as she came, unable to hold back from so much stimulation. Katie kept her head where it was, lips kissing the knot as she swallowed every strong spurt of cum Shar let loose, not a drop spilling. Candace pulled back slowly, letting out a pleasd little sigh as she did so and stroking Shar's bronze hair soothingly.
"Good girl," Candace whispered and was surprised by the head-to-toe shiver of pleasure that ran through the canine. "Ooh, you liked that, huh? How are you feeling, hun?"
Shar panted softly, head tilted back as Katie pulled off her cock slowly, lovingly, swallowing the last mouthful and letting out a soft, girlish sigh of her own. "T-Tired..." Shar panted and was surprised when Katie put the cup of tea back in her paws.
"Have a little drink, Shar, dear," she said sweetly, helping the canine sip from her shaking paws. "It's a bit of a energyy diffusion, we drink it often here. Finish the cup and you'll feel right as rain by the time we get upstairs. <3"
Sure enough, Shar was feeling more energetic, like she'd had an invigorating rest just in time to walk into the master bedroom. This one was fairly soundproofed, she remembered, though the rattling of the bed still came through the walls... hopefully that wouldn't disturb Kacey.
"So, Shar," Candace purred again as she pulled something from one of the night stands, "I'll let you decide this one: do you want to be the top of the bottom tonight? <3"
Shar blushed, her still unsheathed cock already hardening again at the question. Katie skipped up to her mate as the canine tried to decide, lifting her little head to present her neck. Shar watched in awe as a very special black collar was clipped into place around Katie's neck, polished  silver plates on either side bearing both Katie and Candace's names. The two kissed as Shar's heart leapt, imagining for a moment that she was the one clipping the collar around Kacey's neck and vice versa.
"Shar?" Katie squeaked with a curious tilt of her head.
The canine quickly cleared her throat and touched the plain white collar she wore. "I, um, I'd like to... still be a pet. Y-You know, if that's okay... <3"
"Of course, sweetie," Candace said with a grin and crooked a digit at her. "Now, be a good girl and help Katie give my cock a nice tongue-bath. <3"
Shar was only too eager, tail wagging as she knelt and leaned in, breathing the panda's sweet musk and licking at her shaft. It quickly became apparent that both bunny and canine couldn't lick the cock together; Jatie's soft pink tongue was too small and delicate while Shar's Labrador tongue was wide and lapped eagerly. Ceeding the cock to Katie, Shar moved frther south, kissing and licking the panda's heavy black balls, running her tongue all along the underside and feeling a little thrill at the pleased groans Candace made.
"Oooh, good girl, don't stop there, <3" Candace sighed, pushing Katie's head down with one paw to force the bunny to take her cock into her muzzle while the other guided Shar's muzzl a little deeper, her nose moving underneath her lovely sack. An experimental lick confirmed the canine's suspicions: the panda herm wanted her pussy eaten out. Candace was soon moaning louder than before as Shar's broad tongue lapped and licked and slipped in and out of her pussy, eagerly lapping at her arousal while Katie sucked cock like a pro. Soon, Candace had to pull them both back, more than a little surprised by the performance.
"Goodness, you girls are good! <3" she panted, flushed and rock hard but managing to hold back her orgasm. "You make me cum too soon then it won't be as fun, naughty pets. Katie, on the bed, bun. Shar, you're going to do a little 69, puppy. Show Katie how good your cute tongue is and she'll show you how nice her muzzle is. <3"
Candace wasn't kidding. Pinned beneath her, Katie took Shar's thick black canine cock perfectly, sucking and swallowing her length so skillfully that before long Shar could hump with wild abandon, her own golden orbs covering Katie's face over and over as she facefucked the bunny, all while sucking eagerly on the bunny's entire boi package. Her cock and balls were so small, they all easily fit under Shar's tongue. Soon Shar's thrusts were getting erratic, she was so close to cumming and was thankful Candace spotted the sign.
"Go ahead, puppy, give that bunny a nice load of cum, <3" she cooed and Shar obeyed, whimpering with her lips around katie's crotch, dropping her hips down so her knot pressed tight against Katie's muzzle, emptying her balls again and shivering from the sensation.
"My turn for fun, <3" Candace tittered evilly and surprised Shar when she felt the panda's thick black cock press against her own tailhole.
"Mmh?!" she whimpered in surprise and felt Candace's strong arms wrap securely around her.
"Relax, puppy, I know how to make you feel really good, <3" she whispered and pressed again until her whole length slipped into Shar's rump in one go.
"Mmh! Mmmm.... <3" she moaned, still nursing on Katie's member despite the bunny having cum multiple times already. Shar was no stranger to that kind of play either and was thrilled when Kacey penetrated her for the first time in the shower just a little while ago... but Candace was far thicker than her daughter! When the panda started to thrust, Shar moaned so suddenly that the bunny's little packag slipped from her lips, damp and dripping as Shar moaned and whimpered. It was so strange, Candace was nearly the same size as her and just as strong, if not stronger. This was so different, the canine felt small for the first time in a long time.
"Mmgh... <3" Katie moaned beneath them, still eagerly sucking on Shar's member, swallowing like she wanted the knot in her muzzle.
"Go ahead, hun, let her have all she can," Candace whispered encouragingly holding onto Shar as she humped her and helping the canine thrust into Katie's throat. When the panda's strong paws grasped her breasts, Shar cried out in surprise and pleasure. Her nipples were so sensitive and Candace barely needed to touch them to get a reaction. Before long they were thrusting wilding back and forth, Katie now looping her thin arms around Shar's thighs, trying to take that knot to no avail. Finally, Candace came hard in the canine, pulling her back so suddenly that Shar's cock plopped free from Katie and painted the bunny white with another great gush of hot cum.
Minutes later Shar was lying on her back, whimpering again in this new position with her head resting in Candace's lap while Katie straddled the canine, riding that doggie cock at her own pace, still eagerly lapping at the cum in her blue fur. "Wasn't that fun? <3" Candace asked soothingly, brushing a lock of bronze hair from the labrador's eyes.
"Uh-huh... unff..." Shar whimpered, blushing. Her body was too tired to move for the moment despite her arousal, though Katie took that as a challenge and mounted up right away. Currently, the bunny was trying hard to bounce hard enough to take that knot into her tailhole.
"That's good," Candace said with a nod, giving one of Shar's nipples a tender rub. "You're a good girl, Shar. Our daughter's lucky to have you."
"Look!" Katie squeaked and spun herself around into a reverse cowgirl position, making a show as she bounced her cute bunny butt on the knot. "Almost... got... it... Ah! <3" The final bounce popped the knot in and Shar whined again from the intense pleasure. A surprising voice nearly made her blood run cold, though.
"Mommy!" Kacey's voice broke through the pleasure and for a moment Shar thought that everything was ruined, that her relationship was over... until Kacey jumped onto the bed with a big grin and pre leaking from her own throbbing erection. "Move over! I wanna take the knot! <3"
Like mother, like daughter.
