"Hmm..." The twin-tailed yellow fox pondered, walking through the town park. His head turned left and right at a steady pace, like he was trying to pick out a potential target.

After the fun he and Cream had this morning with his new acquaintance Ducky the parasaurlaphus, following the great time he spent with the former and her other unexpected friend, Cassie the pink dragon, he wanted to keep the ball rolling.

Cream was still a growing girl, and after an evening and a morning of intense fun like the ones he just had, she needed her rest. And Vanilla was taking Ducky home, which meant he would have to find another source of his little playtime.

The question for the moment was, who to choose this time?

"Amy? Or Cosmo?" He asked himself, scratching his cheek in consideration. "Maybe Rogue, or possibly Blaze?"

His eyes turned to the benches, where he spotted a couple of good-looking presumable mothers having a chat with one another.

'Then again, how about a human slave?' Tails considered, licking his lips at the sight of the two women. They weren't too young, probably in their mid-thirties, but he definitely wasn't going to turn down a milf.

And the idea of getting his hands on a human certainly intrigued him. For the time being, until he found time to "shop around" for a perfect choice, those two would do just fine.

However, before he could approach the ladies, something stopped him from behind. Specifically, a voice coming from right behind him.

"Pardon me, my child." The unknown female voice, seemingly from something double his size, asked him from out of the blue.

Tails' ears pricked up, his eyes widening at the sound of the strange, and yet, strangely soothing voice. He wasn't sure who or what was speaking to him, but the way she spoke made him feel... At ease? He wasn't really sure.

Regardless, the fox turned himself around, only to be met with a large layer of cloth going vertically.

His eyes widened a little when he took in the sight of whatever was now before him, and once he tilted his head to look at the stranger's face, his eyes went as wide as dinner plates.

There before him was a large goat-woman, standing at about double his height, if not more, towering over the little fox, staring down at him with a warm smile and gentle ruby eyes.

"Whoa..." He muttered, taking a step back to see the giant furred lady properly and fully.

"Sorry to startle you." She greeted politely, taking a knee to see him at eye level. "I'm just glad to meet a fellow monster in this area. What are you doing out here, by yourself?"

"I... I live here." Tails answered, blinking a couple of times as he gazed up at the beautiful stranger.

"Oh!" She uttered, her hands moving to her muzzle. "You've already made yourself at home? That's wonderful~ I don't recall seeing you in The Under."

This made him tilt his head in confusion at what she was referring to.

"The Under?" He repeated, blinking at her once.

"Where we came from, my child." She explained, standing up straight. "Until the barrier was destroyed, of course. May I request a favor? I am not familiar with this town. Would you mind showing me the customs of how these humans act?"

"Oh, uh..." He hesitated, unsure what to make of her sudden appearance, not to mention her request.

But on the other hand, maybe this could work in his favor. VERY well, in his favor.

"I'd love to." Tails responded, grinning up at her, making the goat woman smile.

"Splendid. Thank you very much." She bowed her head, thanking the young fox for his kindness.

The fox smiled gleefully at hi new acquaintance, turning around and keeping his eyes locked on hers.

"I'll take you to my house, first. Then we can go out to see the sights."

"That would be very kind of you, thank you."

"No problem." He replied, taking the lead and leading her through the town.

Whoever this woman was, it made 3 in a row for unexpected new "friends", and hopefully it wasn't going to end here.

***

The two of them arrived back at the house/workshop that the canine called home, and the first thing that Toriel did was take a moment to marvel at the building itself.

"Oh, my. It's a lovely home, isn't it?" She stated, looking over the cozy little home. It was a lot different from the buildings underground, that was for sure.

"Home sweet home." Tails replied, opening the door for her. "After you, ma'am."

"Such a polite little gentleman." Toriel complimented, patting the fox on the head as she ducked down and walked through the entrance.

Or at least, tried to.

Once she got halfway through the doorframe, her waist caught on the door, stopping her.

"Hmm?" She grunted, wondering what had happened. She looked down, seeing the sides of her hips were caught. "Oh dear..."

Tails was stunned, not expecting her to get stuck.

"Oh, wow. That's... Wow." He remarked, his eyes wide at the sight of the huge goat monster's butt jiggling in the doorway.

He hadn't even used his collar on her yet, and she was already turning him on immensely.

"Um, could you give me a hand, my child?" She requested, turning her blushing head and smiling at the fox on the other side of the entrance.

"O- Oh, r- right! Sorry." He stuttered, blushing a little at her rear. He wasn't sure if this was a blessing, or just a coincidence, but either way, he wasn't going to let the opportunity slide.

With his tails spinning, he hovered off the ground and into the air, getting level with the large female's ass.

"O- Okay, brace yourself." He advised, moving a few feet away from the purple-clothed dumptruck.

"A- Alright." Toriel nodded, closing her eyes as the yellow fox readied himself.

Tails pulled his body back, and with his strength combined with his tails, he flew forward and slammed both of his hands against the goat woman's rear, giving her a hard smack across the cheeks as he pressed into them.

"Ohhhh!" Toriel exclaimed, falling forwards theough the door and onto the ground, landing with a soft thud.

Tails landed inside the house too, landing on the goat lady's pillowy arse as she landed flat on the ground, her rear cushioning his fall.

"Whoops, sorry about that." She apologized, getting up onto her feet.

"Oh, don't worry. I'm fine." He brushed off, rubbing his back a little as he got back up. "Had a, uh... So landing. You alright?"

"Of course. I'm a big girl." She assured, dusting herself off.

She looked around the interior, her eyes scanning the entire place.

"What a lovely home." She said, taking a good look around the room.

"Thanks." He thanked her, scratching his neck a little. "Sorry if it's a little messy, I don't usually have many visitors over."

"Oh, nonsense." She dismissed, waving her hand. "I think it's rather charming, just like you."

"Ah." He simply said, trying to think of how to proceed from here. Specifically, to get to the part he was really looking forward to.

'Might as well get on with it.'

"S- So, uh... Let me show you the living room." He suggested, taking her by the hand and leading into the adjacent room besides the entrance hallway, with a thankfully wider archway leading into it.

The goat monster let him take the lead and marvelled happily at the interior of the cozy little quarters.

"Oh my, how sweet~" She cooed politely, looking around at the inside of the room. It was similar to her own in a lot of way, with the chairs, bookshelves and potted plants, though it also had a TV, unlike hers, and a few other decorations and accessories she didn't recognise.

"Take a seat, please." Tails instructed, gesturing his hand to one of the sofas.

"Of course, young man." She accepted, bowing her head in appreciation as she walked over to the sofa and proceeded to sit down on it, making a rather loud sound the moment her sizeable arse plopped onto the lucky cushions, pressing the whole thing down with her immense weight.

The sight and sound of it made Tails all the more eager to get things started.

"I'll... I'll be back in just a sec!" He announced, racing out of the room, leaving Toriel to wait patiently on the couch, while her eyes explored the room.

"He is such a lovely boy." She thought to herself, giggling as she made herself comfortable.

So far, her first impression with being out of The Underground and on the surface was pretty pleasant.

Not too long later, he returned with some kind of device in his hand.

"Here." He offered eagerly, trying not to let his excitement show itself too much, so as to not give away the surprise.

The mammoth-sized milf picked up the collar and looked it over, examining the item.

"Oh..." She uttered, a puzzled look appearing on her face. "What is this?"

"It's a, uh... It's a special device. It's just something to welcome our visitors, and it means a lot if they put it on." The fox lied, making the story up on the spot.

"Oh, I see." Toriel replied, looking at the collar once more. She knew she had to repay her guide for his kindness, and if putting this on was his wish, she was willing to do it for him.

So, without further ado, she placed the strange contraption around her own neck. It was a tight fit, given how thick her body was, but it was just about manageable.

"Thank you very much for this." She said, smiling at him.

"Trust me, it's my pleasure!" Tails responded, activating the device.

Just like with his other slaves, Toriel's mind was completely reprogrammed on the spot, and the only thoughts going through her brain right now were those that demanded complete trust and obedience for the smaller fox.

"So, you wanted to know more about human customs, right?" He reminded, sitting beside her on the sofa.

"Oh, yes. Thank you very much for your help." She responded, smiling at him. "I'm sure there's no-one who knows more of this than you."

"Absolutely." He reassured, smirking up at her as he took a seat. "Well, the first thing you need to do is take off your clothes. It's informal not to be nude at someone else's residence."

The goat lady's eyes widened a little, not realising she may have been disrespecting him with her attire.

"Oh, I do beg your pardon!" She apologised, standing up and bending down to reach the hem of her long dress.

Once again, Tails was treated to the holy sight of her voluptuous behind right in front of him. It was so close that he could practically already see it without the large frock int he way.

After a few seconds of shimmying and wriggling, she was able to pull it up and over her head, exposing her curvaceous body for her new master.

Her taste in underwear was about appropriate for someone her age; a pair of sky-blue granny panties and a classic bra, doing a bit of work cover the majority of her still-large tits.

"Wow..." Tails moaned, already feeling his shaft getting hard from the sight of the semi-nude lady before him, and he knew it was only going to get better from this point.

After dropping the dress to her feet, she reached behind her and unclipped the bra, letting her generous tits into the free air, before letting go of that too, and sliding her thumbs into the waistband of her panties.

As she pulled them down, the lucky fox was pleasantly greeted by the inviting sight of her winking anus and experienced pussy.

If he thought Cassie's was big, esecially for her age, she had nothing on this delicious treat.

And the more she bent over, the clearer it became how wide her hole was, with just the slightest amount of visible gape.

'Wow. This is definitely gonna be a fun ride.' Tails thought, licking his lips hungrily.

After removing her undergarments from her legs, Toriel was finally fully exposed for him, turning around to show off her body.

"How's this?" She asked, somewhat politely and somewhat concerningly, hoping that she doesn't offend him anymore.

"P- Perfect!" He quickly answered, holding hi hand out. "N- Now let me have y- your panties, please!"

"Oh, of course." She nodded, leaning over and handing her underwear to the horny fox.

Once Tails had them, he wasted no time, shoving his face right into the soft fabric and taking in the scent of her mature musk, letting his tongue taste the slightly damp material.

It was noticeably different that then how the Mobian girls' smelt, but not in an unpleasant way.

'Another great addition to the collection!' He thought to himself, taking in another sniff.

The goat lady seemed pleased at his delight in her scent, sitting her bare ass down on the couch again, making him bounce a little from the sudden weight shift.

"What else may I do?" She asked clamly, looking hopeful that she would be able to please her new friend.

Tails didn't need to think about it, placing the underwear down and looking to her.

"W- Well, would you mind if I spanked you?" He requested, pointing to the massive rear behind her.

"Of course not, my child." She assured, nodding her head. "Go ahead."

She leaned down, getting herself over his lap on the sofa and presenting her huge rear, offering her soft cheeks for the young fox's amusement.

Of course, it took him a moment to adjust to how heavy she was. It took a little air out of him when she lied down over him, and her butt was almost as his chin level.

Still, he managed just fine and rested his hand on her marshmallowy pair of pillow that she called her posterior.

"You know, you're a very cute boy." She remarked, turning her head to see him, a gentle smile on her muzzle. "It's been so long since I've had someone so adorable and helpful around me, let alone discipline me like this. Thank you ever so much for your kindness."

"N- No pr- problem!" Tails replied, smiling nervously as his face turned a bright red, feeling a little weird having the beautiful milf talk about him like this.

Regardless, the young fox took a deep breath, and then proceeded to bring his hand up, bringing it back down on her a moment later.

She didn't give much reaction to the first strike, just continuing to smile lovingly at him.

Tails blinked a couple of times, wondering what to make of this, before giving another smack across her rear, with a little more force this time.

Toriel's expression remained unchanged, though the second spank made her body twitch a little.

He gave her another, and another, and another, getting mesmerized by the way it rippled and wobbled like waves in the ocean, jiggling around and shifting like a bowl of jelly.

With each hit, the fox began to feel his palm getting warmer, and the more he kept going, the hotter it got, and the faster his hand went, getting excited by the sight of her rear shaking and jiggling the way it way.

He couldn't even bring himself to continue this, as he wanted more. Much more.

"O- Okay, you c- can get off!" He said, moving his arms out the way as she slid herself off his lap, her butt brushing up against his erection as she moved to the other end of the couch.

"Is everything alright?" She asked sweetly, looking at him with some concern. "I hope I'm not troubling you."

He looked back at her, and from the way she was sitting down right now, he had an ideal sight of her plump breasts. Hands down, the biggest he had ever seen, and his cock was begging for him to have his way with them.

"N- No, everything's fine." He assured, waving his hand. "B- But, your, um... Your mammeries..."

The milf looked down at her pillowy chest mounds, grapsing them gently and moving them about a little.

"Oh? What about them? Are they causing you distress?" She asked, worried she was offending him with her appearance.

"No, n- not at all!" He answered, his face blushing a deeper shade of red. "It's j- just that, um... W- Well, it's a c- custom to offer your m- milk to anyone who asks."

Toriel's eyes lit up with realisation.

"Oh! Yes, of course. Why didn't I think of that?" She responded, shaking her head at her mistake and she opened her arm. "Come, my child."

Tails wasted no time, diving into place on her lap this time, latching himself onto one of her enormous breasts and began suckling away at the nipple, gulping down her sweet and delicious milk.

"That's it. Drink up." She encouraged, patting his head and stroking his head as he fed. "There's plenty of it."

She could feel his erection twitching about, and knew she had to do something about it accordingly. So she reached down and too ahold of his boner, giving it a gentle tug and stroke as she watched him suckling.

"Ah, I see you're quite pent up." She observed, noticing the way he shuddered at her touch. "I can help you with that, if you like."

Tails couldn't answer, as his mouth was occupied with her milk, but the way his body was feeling told him that he didn't need to.

She proceeded to start giving him a handjob, moving her hand up and down his shaft gently while he sucked on her milk like a child.

This was heaven for the vulpine, and nothing on Earth would've made him want to come back to the world of the living.

He continued to feed off of her delicious breastmilk for several minutes, before his eager dick told him that the impending climax was getting closer and closer.

His tails spun wildly, his eyes rolling up, his entire body twitching and his mind becoming hazy and fuzzy as his orgasm was rapidly approaching.

And then, without warning, his jizz shot out of his shaft, firing upwards and landing on the goat lady's chest, which made her smile and giggle, enjoying his liquid happiness.

Tails was out of breath after such a heavy climax, releasing her nipple and lying his head on her breast, panting loudly.

"I'm so glad you enjoyed that, my child." She declared proudly, taking notice of his still-hard cock in her hand. "If that is merely a warmup, I'm sure this means casual intercourse is to follow?"

Tails couldn't answer her verbally, instead moving his head up and nodding blissfully.

Toriel just smiled and stroked his head, gently helping him off her and getting on his knees on the couch cushions, before she got into position as well.

She proceeded to climb onto her hands and knees, pointing her delightful rear at the fox, even using one hand to spread her cheek to further show him the goodies on offer.

"Here you go, my sweet~" She cooed, throwing him a flirtatious look over her shoulder.

Tails just couldn't wait anymore.

He leapt up from his seated position and threw himself to her backside, his hard cock slipping straight into her wet pussy, with his body landing right between her thick pair of cheeks, her soft fat cushioning his fall.

"Aaaahhhh!" He exclaimed from the heavenly insertion that he felt upon getting into her cunt.

"O- Oh!" She uttered in surprise, feeling her snatch getting penetrated by his eagerness. "Oh, my goodness..."

Her snatch was a tight fit, not as much as Cassie's, but it was enough to make Tails feel a little more restricted than usual, though not to the point where it was anything near to be uncomfortable.

Without skipping a beat, he thrust himself in and out, back and forth, to and fro, pleasuring both himself and his voluptious guest.

"Aaaahhhhhh..." She moaned, her body trembling from the pleasure.

He didn't know whether to look at her face, or her amazing rear. It was a difficult decision, but in the end, he settled on the latter, taking ahold of her hips to steady himself more as he got to work in fucking the older beast like his life depended on it.

She must've been a mother too, by the way her pussy was somewhat similar to Vanilla's, but that didn't make him love her any less.

In fact, it was quite the opposite.

He began thrusting himself a little harder, grunting as his body pressed against her massive, wobbling ass, slapping his crotch against her rear as he rammed his rod into her soaked womanhood, making the both of them moan delightfully.

The two of them went at it like a pair of wild animals, their mating instincts taking over all else and getting lost in the moment.

Toriel was in a similar state of bliss, enjoying the young fox's cock inside her. It was a strange feeling, being with a youngster, but not an unwelcome one.

And his balls were so heavy, so full, and so eager to please her. She was so grateful that such a sweet, handsome, cute and thoughtful young man like him would even give an older lady like her a second glance, let alone want to actually make love to her.

As for Tails. he was also grateful to have such an incredible new slave come to him, putting her full trust and faith into him without even getting the collars involved. He'd definitely have to get her involved with the other girls at some point, especailly Vanilla.

But alas, it was going to be over all too soon for the pair, as they could feel themselves getting ready to reach their harmonious big finish. For the female, it had been such a long time since she had done this for anyone, so she knew she was going to make quite a mess after she came.

"Ahhhh, m- my child!" She moaned, feeling her orgasm rapidly approaching. "I- I feel th- that I'm going t- to-!"

"Y- Yeah, I- I'm g- gonna cum, too!" Tails stammered, feeling his cock begin to pulse.

"Th- then let us... B- Bond our.... Our love!"

"Y- YES!" He roared, slamming his crotch against her as hard as possible, trying to bury his length as far as he could into her womanhood.

"AAAAAHHHHHH!" The screamed in synchronicity, feeling them fill each other up from the other side.

The male's cum began filling up her uterus, with her lovejuices spurting out and all over his dick and crotch.

The feeling was so great for the yellow fox, it almost felt like her vagina was draining the cum from his balls, which he certainly hoped WAS the case.

And Toriel could feel her cunt welcoming everything the fox had for him, taking it all in and swallowing it all up.

Both of them could feel their bodies twitching from the powerful climax, their eyes rolling up, their faces contorting, and their tongues lolling out.

Once the intense moment had ended, Tails collapsed onto her huge, cushiony rear, panting heavily after such an amazing activity, whereas Toriel had to straighten out her body to lie doen properly, allowing her new partner to rest himself on her plump, soft, furry ass.

"How... Was that?" She asked, her voice a little breathless from the activity.

"S- S- S- So good..." He answered, smiling tiredly as he looked over her butt.

She giggled, a little exhausted from their mating session, but nonetheless satisfied with her new master's performance.

"Please... Take a rest... My love." She insisted, closing her own eyes as she smiled contently. "I hope... My bum will... Make for a nice bed."

"I... Agree..." Tails agreed, his eyelids beginning to droop.

Before the both of them knew it, the two fell asleep, with Tails on Toriel's massive posterior, and the goat-woman with a happy smile on her face.
