#grilster

It wasn’t very often that they could escape to the Mainland.  After so many years there was still so much unrest between the two groups.  Small groups of humans would attack the monsters and those who were friendly to them without warning, and the laws of the monster integration were written in a way that made it impossible for them to retaliate.

Sai and Bucky had already met their fair share of these Anti-Monster warriors, seeking to “save” them from their “captors”.  These men offered many gifts and promises, but seemed deaf to Sai’s and Bucky’s words of no.  Luckily, aside from the one instance with Grillby, there had been no violent altercations.

Today, the boys were sure that there was going to be no such problems.

There were talks of a new law being written, one that would finally give monsters the same legal rights as humans.  The little attacks against the monsters of Undertale had worked against the Anti-Monster Groups.  There was a need for their protection…

But they weren’t going to think about that right now.

Gaster and Grillby sat on the little bench in the local mall, sighing softly.  There were several shopping bags between the two of them. It was their monthly shopping trip and they had needed a few more supplies than usual.  Food, artistic supplies, clothing, household and others. They were just about finished their entire list.

There was just one more thing.

“Alright. It is time for my hair appointment.” Sai said, tossing her red and purple hair over her shoulder.  It contrasted magnificently with her star-studded hoodie.  “Vixen can’t fit me in for a while and I am simply dying for a good, shampooing massage. Her paws just don’t cut it sometimes.”

“I like your hair long, do you really need a cut?” Gaster grumbled softly, no heat to his words. He wasn’t against the haircut itself, just more against anyone else touching his, their, Sai.  It was difficult enough sharing her with the rest of her mates back at the mansion some days.  Grillby silently nodded, his hands full of bags.

Sai giggled softly, pressing a soft kiss to both Grillby’s and Gaster’s foreheads.  “Just a trim, I promise,” she told them with a small wink. “I know how much you both love my long, flowing locks… besides, Vixen would kill me if I did anything drastic without her approval.”

Oh, it was true. They both loved her long hair. Especially when it cascaded down her back, sticking to her flushed and sweaty cheeks…

“Bucky, you sure you don’t want a cut?” Sai turned to her friend now.

Bucky sighed sounding slightly longing.  “I would but they don’t have anyone who has been trained on curly hair yet.  I already asked them when you made the appointment.  Maybe we will have to run into a different salon and see what they have.”

“Next time then. May the stars forbid that the same guy cuts your hair again.”  Last time Bucky went in for a cut with Sai, the hair cutter had not been properly trained with curly hair and, once his style had worn off, one side of her hair had ended up being two inches shorter than the other.

Stretch wrapped his arms around her.  “I will find someone for you,” he promised her, nuzzling against her cheek.  “No matter how many hair stylists I have to comb through.”

Sai and Bucky shared a groaning laugh at his pun.  “Ok. I’m off. See you guys in a bit!” Sai said, waving back at the gang as she entered the salon.

It was about thirty minutes later. Grillby and Gaster were watching something on his phone and Bucky was still entangled within a purring Stretch’s arms. They were comfortable, not yet worried about Sai.

There was a sound of approaching footsteps and Grillby looked up first.  He was a little more on edge since his attack, the first to react to sounds.  He gave a muted gasp and grabbed Grillby’s arms, gesturing.  Gaster looked up from his phone and saw what Grillby was gesturing at.  “HOLY FUCK SAI.  HOW ON EARTH WAS THAT A TRIM?”

Stretch and Bucky looked up in shock.  They had never heard Gaster scream like that before.  They turned…

And saw a confused looking Sai, hands jammed in the sweater pockets.  There was no mistaking the galaxy hoodie (a present from Gaster), Sai’s green collar with the golden tag…

And those purple and red locks, now trimmed into a short military cut.

“Holy shit… it looks good Sai, it really does…” Bucky said, eyes widening.  “But damn that’s a lot of hair.”

Those hazel eyes flicked back and forth between the entire group, confusion slowly fading and that mischievous spark returning to them “Heh, what can I say? I’m full of surprises.” Sai smirked and sat between Grillby and Gaster, grinning at them. Arms wrapped around them, pulling them close.  “And I know that is part of the reason why you love me so much,” Sai said in a husky voice.  “How many more surprises can you take?” Sai grinned, squeezing their shoulders. “Because, if you’re up for it, I say we ditch the shopping and take this party into a more secluded area and have some fun.”

Grillby and Gaster looked up at Sai and then to each other. “Uh…” Gaster said, thoroughly confused. It was one thing for Sai to get a radically different haircut than they were expecting, but another for Sai for wanting to bypass their coffee spot and… well, she was horny at the best of times true.

But enough to give up coffee?

“What is the meaning of this?” a familiar voice said, sounding slightly irritated.

Heads turned and saw another Sai, this one with long, flowing hair, this one with more feminine features. The other Sai grinned and continued to drape his, it was a definite masculine air about him, his arms over the two monsters’ shoulders.  There was a slight buzz of hair on his chin, one that had been missed in the initial shock.

“Sai?” Gaster asked, looking between the two humans.  There was little difference between the two of them.  If Gaster and Grillby had not known Sai’s family personally, they could have sworn that this other Sai was a twin.

“Yes?” The two humans asked, both looking at each other.  “He’s talking to me,” they said in unison, the same eyebrow arching up slightly.

Grillby couldn’t help it.  He snorted and covered his face, shaking his head.  Only they would meet Sai’s genderbent twin on the mainland.  If only the rest of her mates could see this now.  They might explode from a mixture of joy, surprise and hunger.

The male Sai smiled at them.  “Yes, I too am named Sai,” he said, “but call me Yuri, for confusion’s sake.”

Sai huffed and folded her arms.  “So, care to explain why you were making a move on my fiancés?” she demanded.

Yuri raised his eyebrow again.  “And I trust that you wouldn’t make a move on mine if you had a chance?”  Flushing, Sai huffed at him.  Yuri interrupted before she could speak again. “You can’t say that you wouldn’t jump at such a chance.  I know myself a little too well.”

“You have no proof of that!” she snapped at him.

Bucky pulled slightly on Stretch’s arms.  “I always did know that she was her own worst enemy.” She whispered, causing Stretch to chuckle.

“Really?” he hummed, looking over his shoulder.

Following his gaze, Sai gulped.  There was an orange flame monster, willowy and slim, wearing a trim little suit. Turning, Sai saw that this female flame monster was rather gifted.  Beautiful and lush, Sai felt her mouth watering.

“Checkmate,” Yuri said, winking at her.

Sai flushed and shook her head.  “I…”

“Or perhaps…” standing beside the flame monster was a skeleton, eye lights lit up with a pale purple, also dressed in a form-fitting blouse and skirt, showing off her pale ecto-breasts and ass perfectly.  They were as beautiful as her mates were handsome.  Showstoppers.  Any of them on their own would have been stunning.  Together…

With a sigh, Sai turned to Yuri.  “You win this round.” She simply said, admitting defeat, extending her hand to the other version of her.  

To her surprise, Yuri kissed her hand instead, eyes flashing at her.  “We have to go, Grilz has a shift starting soon.  But,” he said, handing her a piece of paper, numbers written on it, “if you ever, ever get the urge to switch partners or see how good you are in bed,” he gently folded her fingers around the paper, “give me a call.” He said, giving her one more wink before walking away from them, coming up to the other monsters’ side.

The small group watched the three of them interact and watch off, realizing quickly that it was like looking in a mirror.  “Well, that went a lot better than I expected,” Gaster said, sighing softly and picking up most of the bags by his feet.
