The Great Valley was a place for all kinds of herbivorous dinosaurs. The leaf-eaters and the root-pullers could live side by side without worrying about a predator.

As such, travelling herds would often come and go as the year went by, and one such herd was the one belonging to Ali.

Ali was a young Apatosaurus, along with her entire herd. She was the same age as Littlefoot and his friends, and although she wasn't officially part of the group, the gang was more than willing to help her out, whether it be fending off a few sharpteeth, or just giving her company.

Ali and her herd had spent the night in the Great Valley, but today was their last day in the area. They were due to head south to the lower land, where the grass was more abundant.

While the young longneck was savoring the last moments she would have with her friends for another year, her mother was by herself, taking in the scenery, before she would have to leave once again.

"It's a lovely place, isn't it?" A stranger's voice asked, accompanied by the treading sound of approaching footsteps.

The longneck mother turned around to find another one of her kin; an older one that wasn't part of her herd.

"I suppose so, but I don't think it's good for Ali." She replied. "There are far too many sharpteeth that make their way in here, like Red Claw. It's not safe for her."

"Well, I've been living in these parts for a while now, and I can vouch for its safety. I have to admit, the food's not always reliable, but it's the only place where you don't have to worry much about sharptooth attacks." The stranger continued, walking up to the mother.

As she got closer, it appeared she had quite the flirtatious look on her face. Ali's mother wasn't sure why, but this didn't seem to alarm her much.

"My name is Sue." The bigger longneck introduced, stopping only a few feet from her new acquaintance. "What's yours?"

"Patty." Ali's mother replied.

"That's a beautiful name. I take it your mate is somewhere in that herd?"

"I'm afraid not. I don't know where he could be right now, but he hasn't been part of my life since Ali hatched. I haven't seen him since then."

"I see." Sue said, looking rather dejected. "So, you're available, then?"

This caught the mother of one off-guard, having not expected such a forward question with someone she only just met. But for whatever reason, she already felt at ease, in Sue's presence.

A little odd, given the almost overwhelming size of the other female longneck, but maybe that was just it?

"Well, if you're saying I'm not mated, then yes, I'm available. But what does it matter?"

"Maybe nothing. Maybe something. Would you like to find out?"

Before Patty had a chance to respond, she suddenly found Sue's snout up against her own, her pretty eyes flashing before hers.

"You're very beautiful."

"Oh, t-thank you." She responded with a blush, unsure if she wanted to accept her advances or not. "Um, what were you-"

"I was just getting your attention, dear." Sue said, moving a bit closer, pressing her neck up against Patty's. "I must confess, I've been watching you for a while, now. You're so beautiful, and the way you look after your child is really adorable."

"Oh, you've been watching me? I never noticed..."

"I can't blame you. Despite my size, I like to think I'm a very stealthy observer. And I have to say, your bum is amazing."

Patty had never received such flattery before, especially from someone she didn't even know. This was so strange, and yet, she was kind of enjoying it.

"So, I have a proposition for you. How would you like to mate?"

"What?! Right now?"

"Why not? It's a great day, isn't it? The sun's out, the plants are growing, there's hardly any cloud in the sky, and a beautiful, mature lady like yourself would look absolutely amazing underneath me."

"Um, thank you, but... I'm not sure. This is a bit sudden, and I have a child that needs me."

"Don't worry, my dear." Sue assured her, rubbing her neck up against hers. "I'm not planning to keep you away from her. After all, if you're going to be my mate, we'll both have to be able to take care of her."

"Wait, 'your mate'? You mean you're asking me to mate for life?"

"Yes. I think you're a wonderful specimen of our species, and I think we'd make a lovely family. I promise, I'll do my best to make sure Ali's happy."

Patty had no idea what to say. This was so unexpected, and she hardly knew this girl, and yet, her words sounded so sincere, and the look in her eyes was so genuine, that she actually wanted to give her a chance.

"Very well. I'll do it."

Sue's face lit up with delight, before she pulled the smaller longneck into an embrace. "Oh, you won't regret it, I promise. Come, let's get started."

The two headed further away from the herd, into a secluded area, where the bushes and trees obscured their view.

After they got themselves comfortable, they positioned their bottoms close to each other, so that they were nearly touching.

"So, uh, how are we going to do this?"

"Just let me handle everything, my dear." Sue assured, swinging her tail so that it smacked against Patty's rump.

The mother of one let out a gasp, blushing from the impact, and feeling a strange, pleasurable sensation in her nethers.

"Now, don't hold anything back. Let those juices flow."

The older longneck's tail swiped across her lover's rump again, and the resulting jolt was even stronger. Patty felt her loins begin to drip, as her arousal rose.

She didn't understand what was happening, or why she was feeling this way, but she couldn't help herself. There was just something about the way Sue moved her tail, and the look in her eyes, and the sound of her voice, and...

"That's right. Good girl." Sue cooed, as she kept her tail moving. "You're doing great. Just let your body do its thing, and you'll have a wonderful climax in no time."

Patty moaned, and her legs buckled, as she leaned against a nearby tree, struggling to stay upright. Her juices were leaking down her hind legs, and her clit was throbbing, as she felt something coming.

Something she hadn't felt for the longest time, but as soon as the rush came back to her, she missed it dearly.

"There we go, honey." Sue encouraged, bringing her tail up to smack her rump again. "Come on, you're so close. Don't hold back."

"Ah! Sue!"

Her clit was so big, and it was begging to be released, and just as the older longneck was about to do it, the mother of one lost control, and her orgasm erupted out.

"Mm, yeah, that's right~ Let it all out, sweetheart~"

Patty's juices flowed like water, drenching the ground beneath her, and splashing against the base of the tree she was leaning on. Not to mention getting in the lake the two of them were indulging each other next to.

And on the topic of that lake, if either route them payed closer attention, they may have noticed that they were being watched by something, or rather someone, from beneath the surface.

Meanwhile, Sue was pleased with how this was going. Her new girlfriend was a real cutie, and a fun one, at that. Not to mention she was pretty sure she just made her submissive to her, after all the punishment her lovely flanks just took.

She couldn't wait to do this again, and show her all sorts of different techniques.

Unbeknownst to the pair of them, that was going to be sooner than they thought.

Even with Patty lying down from the intensity of her orgasm, both longnecks gazed lovingly into each other's eyes.

Sue was already standing taller her new lover when they were both on their feet, but now, she just an aura of absolute power over the milf.

"I'll give you a chance to rest, and then, we'll do something a little more, shall we?"

"O-okay."

As the older longneck looked down upon her, and rubbed her neck up against hers, her mind couldn't help but go blank, and all she could think about was her.

Sue's mind had the same mentality, as Pattu was now all she could see in her head.

Even more so when she pulled her neck away from hers, looking deep into one another's eyes with pure passion. It didn't take long for their mouths to meet.

Their tongues slid into each other, and wrapped around one another, as their lips were pressed together, and their saliva mixed.

Patty had no idea what was happening, or why Sue's tongue tasted so good, but she wasn't complaining. She'd easily trade 100 tree sweets for the feeling of her mouth.

The mother of one moaned, and her pussy clenched, as the two of them shared their saliva, and their breaths.

Sue pulled away, leaving a trail of spit connecting the two. "You're a wonderful kisser, my dear."

"Thank you." Patty responded with a blush.

"I'll give you a little while longer, and then we'll continue, okay? And this time, it's your turn."

"Okay. But, I've never done something like this, before. What am I supposed to do?"

But before she could answer, the sounds literally coming out of the water caught their attention, as well as a polite "Hello, girls."

Turning both their heads to the lake, they were shocked to see that someone else was right there with them. At first, it was an instinct of fear, concerned that they may have been fou d out by a friend of theirs, or a peeping Tom of some kind had found them.

"I'm sorry, I hope I'm not intruding, but I couldn't help but notice that the two of you were enjoying yourselves." She said as she walked out of the water and over to the pair of them.

Both of the longnecks were surprised by the stranger's appearance, and her sudden interruption.

She appeared to be a parasaurolophus, or Swimmer, as they were commonly known as, and hitting around Patty's age. Sue was sure she had seen her before, as one of Littlefoot's friend's mothers; that little green Swimmer. And the adoptive other of another one of his friends; the dark green Spiketail.

"I'm sorry. I don't mean to ruin your time together, but I was just wondering if I could join you."

"How long have you been there?" Sue asked, a little confused as to this spectator's reason for spying on them.

"Not that long, but long enough to see your... activities."

"And you were just watching?"

"Yes, I was." The Swimmer confirmed, with a look of excitement on her face. "I've always thought that the love between two ladies is so beautiful, and watching you two has been truly inspirational. That, and with as many kids we Swimmers have, it should come as no surprise that I'd be eager to partake in these kinds of activities."

"You want to... mate with us?" Patty asked, a little unsure if she should trust this newcomer. She certainly seemed genuine and a sweetheart, but it still didn't feel right.

"Only if you want me to." The Swimmer responded, approaching the mother of one as Sue got out of the way, getting on her knees. "May I, dear?"

"I guess so. I've already accepted a mating request, so I might as well accept one more."

"Wonderful." She smiled, before closing her eyes and holding out her tongue.

With that, the Swimmer brought her head down to Patty's snatch and began licking, cleaning up the mess that Sue made from inside it, much to the longneck's delight.

"Oh, yes~ That's good~" She moaned, feeling the stranger's tongue lap up her juices.

The Swimmer was happy to hear her praise, and continued lapping up her sweet fluids, making her way towards the entrance of her hole.

The older female couldn't believe this was happening. Just minutes ago, she was mated by Sue, and now, she was mating with this stranger, who was giving her the best pussy-licking "clean up" of her life.

As for the longneck herself, she was quite content to just watch her new girlfriend get pleasured, while she played with herself using her tail.

She couldn't believe this was happening, but her pussy was getting so hot, and her juices were dripping, and the sight of the mother Swimmer's tongue slithering around Patty's lower lips was so enticing.

Patty had her eyes shut tight, as her tongue lolled out. This felt so good, and her loins were burning with pleasure.

"Ah, yes, that's the spot~ Keep going, darling~"

The Swimmer had no intention of stopping yet, but she knew she had to; she was just cleaning up the mess for now. She needed to get her nice and ready for her real treat.

With one final lick, she pulled her head away, before quickly walking over to the older female's side, and pulling her in for a kiss. Luckily, she was already level with her own head.

Sue was surprised at the sudden forwardness, but it was strangely exciting, so she had no worries about what she was doing.

Sue's tongue slid into the stranger's mouth, as the pair passionately shared their breaths, and their saliva.

"Ah, how sweet~" Patty said panting, as she watched the two of them make out. She'd be lying if she said that didn't turn her on, and despite her exhausted condition, she could feel her pussy throbbing once again.

Finally, the Swimmer pulled away, leaving a trail of saliva between the two. "You're a great kisser, darling."

"Why thank you, dear." Sue smiled, before she leaned her head down, and gave the stranger a quick lick on her snatch.

"Oh, goodness, that's nice." She commented, before turning her attention back to Patty. "Now, let's get you ready for the real fun."

"The real fun?"

"Yes, dear. Now, if you'll allow me."

Before the older female could respond, she suddenly found the stranger's tongue in her pussy again, and she couldn't help but let out a moan, as the Swimmer worked her magic.

Only this time, it was deeper.

The mother Swimmer's tongue slid right into her vagina, and licked the walls, sending shivers down her spine.

"Ooh~ Yes, dear, that's the spot~"

The stranger was happy to hear her praise, and continued licking, making sure to coat every inch of her pussy in her saliva.

Sue was more than happy to keep playing with herself, and she could already feel her climax coming, but the sight of her lover getting fucked was a wonderful treat.

So much so that she felt it wrong to leave this newcomer unrewarded, so she reached down with her tail, and swiped it across the stranger's bottom.

"Oh!" She yelped, as she felt the longneck's tail spank against her flanks, before her own loins leaked. "Oh, yes~ Thank you, dear."

Getting into it, the mother Swimmer straightened her legs and lifted her tail, further exposing her lady parts to the bigger Longneck.

With the Swimmer's bottom now exposed, and her snatch now dripping, Sue felt it was time to show her just how good her tail really was.

And she wasn't disappointed.

The Swimmer let out a squeal of delight, as the bigger longneck's tail slammed against her ass, harder this time, sending jolts throughout her body, before wiggling her bottom from the impact.

"Ah! Oh, yes, dear! Spank me again! Make me yours!"

Patty couldn't believe this was happening, and she certainly wasn't expecting it, but it was definitely an arousing sight, watching the stranger get spanked while she licked her pussy.

It didn't take much longer for her to reach her peak, and she let out a scream, as her climax burst out.

Her juices splashed onto the Swimmer's head, and she lapped up the sweet nectar, as the longneck's legs quivered.

"Mm, you're delicious, dear." The mature Swimmer complimented, licking her big thick lips at the taste, before diving them back in to clean up more of the mess she made.

"T-thank you." Patty managed, struggling to speak as the feeling of pure ecstasy started to fog her head.

"My pleasure. And now, it's time for the big finale." She announced, pulling out of the milf's private cave and turning back to look at Sue with a seductive look. "Dear, I want you to sit on me."

The largest dinosaur of the trio raised an eyebrow with a somewhat startled expression.

"Sit on you?" Sue asked, unsure if she had heard the request correctly.

"Yes, darling. I'm going to take you for a ride." The mother Swimmer answered, keeping that sexual look in her eyes the entire time.

It was amazing how confident she was in having sex with almost complete strangers. It was like she knew exactly what would bring them bliss, without even asking a single question.

"Oh, I'd love that." The tall dino gal remarked, shooting Ducky's mom a similar kind of turned-on gaze.

That same mom proceeded to slide down on her tail until she was sitting on the ground, lying down so she was face-up in a spot where the Longneck would be able to squish her with that alluring ass.

"Well, then, get your lovely, enormous bottom over here, and we'll get started." She cooed, looking more ready than anything right now.

"Alright, then." Sue smiled, and turned around, walking over to the stranger, with her rump swaying.

The Swimmer watched her rear move, her loins getting even wetter, before she stopped a few feet in front of her.

"That's right, dear. Just sit right there." She instructed, barely able to contain her excitement.

"With pleasure." The older longneck cooed, lowering her behind, as the Swimmer held her arms out for the incoming scaly rear.

Sue continued to lower her butt, steadily as it was grasped by the Swimmer's gentle hands, pulling her downwards until she was eventually sitting on her lover's snout.

In fact, almost all of Ducky's mother's body disappeared under the mass of Sue, with her rump engulfing her entirely up to her shoulders, let alone just her snout.

"Oooh, that feels good~" Sue moaned as she felt the face meet her naughty spots: her pussy and anus. "Alright, then. Let's get started."

Not that she needed to be told; without any hesitation, the mother Swimmer's tongue came out, probing into Sue's butthole.

"Oh! My goodness!" The older Apatosaurus moaned loudly at the feeling of her colon being played with.

"Just relax, dear." The mother Swimmer encouraged, amazingly managing to get her words out relatively clearly, despite the overwhelming mass of flesh on top of her right now. "Just let yourself enjoy it."

"I-I'm trying..." She stammered, as her dirty hole was teased, and the mother Swimmer's fingers proceeded to play with her pussy.

The older longneck's juices trickled onto the ground, and she leaned her head back, as the stranger's tongue moved further into her bottom, exploring the depths of her hole.

Of course, Sue wanted to return the favor. So, she lifted her front half up and pressed her arse into Ducky's mother's face even further, so that the latter's own pussy was better exposed.

Lowering her head to her slit, Sue started licking her in her own private area, much to the amphibious dinosaur's delight.

"Ah, that's wonderful." The Swimmer gasped in a muffled voice, with her tongue still lodged deep in the older longneck's bumhole.

Sue was glad to hear her approval, or at least its interpretation, and continued lapping at her pussy, making sure to clean every inch of the soaking wet clit.

Meanwhile, the mother Swimmer kept up her own work, pushing her tongue deeper into the older female's arse, and stretching out her main hole as she began to insert her whole hand into the big Longneck's cunt.

"Ah, yes... Keep going, dear.... Please don't stop..." Sue panted, feeling herself getting close to the finish.

The Swimmer was only too happy to oblige, and continued her oral assault on Sue's ass, pushing her tongue in as far as it could go, and her fist probed her pussy. It wouldn't take long before she reached her own climax.

"Ah, I'm almost there, dear!" She exclaimed, reaching closer to finishing. "K-keep going! Don't stop!"

The mother Swimmer was determined to keep up the pace, despite how difficult it was getting getting breathe under there, and she pushed her hand further into her, reaching deeper and deeper into her pussy.

Sue's legs quivered, and her pussy dripped, as her orgasm drew closer. She could hardly hold herself up anymore, and she knew it was only a matter of seconds before her climax finally came.

Finally, after a few more moments of being toyed with down there, Sue couldn't hold it in anymore. Her vagina quivered as the love juices began to flood like a river with a broken dam, gushing its way down to the face of the Swimmer below her.

And as it did, her whole body tensed up, and her juices splattered onto the mother Swimmer's hand and arm, but she wasn't the only one that hit her peak.

While it may not have been perfectly synchronised, both adult dinosaurs let out their orgasms at the same time; once she felt that she could so much as smell the incoming geyser of Sue's love cream, Ducky's mother began to explode with her own juices, spreading her legs further as the jizz squirted out from her love cave onto her new lover's face.

Both of their fluids gushed out, and their bodies trembled, as they rode out their orgasms together. Their faces were both covered in the other's fluids, but neither one was in a particular rush to clean themselves off.

Patty was enjoying the show nearly as much as she enjoyed both of her own orgasms. She had a sneaking feeling that the fun wasn't over yet, and she was eager for whatever else the three of them were going to be doing.

When it was all over, both females were panting, and the older Longneck slowly and reluctantly lifted herself off the other female, taking the poor Swimmer away from that anal delicacy and allowing her to breath fresh air again.

"Oh, goodness..." Sue panted, looking down at the mature Swimmer under her rear. "That... That was wonderful..."

"Indeed, it was... My dear..." The mother of many agreed, before the pair of them looked at Patty.

It was clear the three of them were ready for the big finale, and they wasted no time, positioning themselves.

Sue and the Swimmer stood next to each other, their tails touching, and their holes pressed together, while Patty laid down in front of them, her rear end sticking up, and her pussy wide open.

"Are you ready, dear?" The Swimmer asked.

"I am, dear."

"Wonderful. Now, let's begin."

And without wasting another moment, the two of them began their tail fucking.

Their tails wiggled, and their hips moved, as their rumps rubbed against each other, and their holes were stretched, and their clits were teased, and their juices were exchanged.

The Swimmer could hardly believe how good it felt, and Sue was more than willing to indulge her. After all, they were now both submissive to her, and they would happily do whatever she wanted.

But, for now, all she could focus on was making sure the mother of one felt good.

Her hips moved, and her tail waggled, as her pussy was stretched, and her clit was teased, and her juices were leaking.

Patty couldn't believe how amazing this was, and she couldn't wait to cum. She was already on the edge, and she knew it wouldn't be long before her climax hit.

As for Sue, she was enjoying herself, and she couldn't help but think about the future, and how she'd spend the rest of her life with her new lovers.

The Swimmer's legs were quivering, and her loins were dripping, and her body was tense, and she knew her orgasm was close.

Patty couldn't hold it back any longer, and her orgasm exploded, sending her juices everywhere, and coating her lovers' rumps.

"Ah, yes! That's it, dear, give me all of your cum!"

"Yes, my love! I'm so close, too! Let's cum together!"

The two of them continued their tail fucking, and their loins were burning with passion, and their bodies were trembling, and their climaxes were getting closer and closer.

Sue could barely hold back any longer, and her own orgasm hit, her juices splattering onto the Swimmer's ass and her own, and she couldn't help but moan with the satisfaction.

"Mm, that's right, dear, cum for me. I want to feel your juices on my rump."

"Yes, my love! Your wish is my command."

The Swimmer couldn't take it anymore, and her own orgasm came, her juices gushing out, and covering her own ass and the Longneck's, as the two of them moaned in pleasure.

"Ah, yes! That's the spot, my love! I'm so close."

"Don't worry, my love, I'm almost there, too. Just a little more."

The Swimmer could barely speak, her mouth was hanging open, her tongue hanging out, and her eyes were glazed over, and she was panting like a beast in heat.

Sue couldn't believe how hot this was, and her legs were shaking, and her body was trembling, and her orgasm was so close.

Finally, the Swimmer's legs gave out, and she collapsed, falling onto her belly, and Sue came too, her juices spraying onto the ground, and her body shuddering, and her eyes rolling back, and her mouth hanging open, and her tongue lolling out.

The Longneck's legs gave way, collapsing on top of the mother Swimmer, unintentionally pinning her down with her larger frame.

"S-sorry... Dear..."

"D-don't... Worry... About it..."

As the two of them panted, they couldn't help but wonder what kind of family the three of them were going to make, and they couldn't wait to find out.

Patty lied down and joined them on the ground, nuzzling up to Sue and resting her head on top of hers.

And so, the three of them basked in the afterglow, with the sun shining down on them. All was well in the world, as far as they were concerned.
