Undertale Tickle Stories (Main Series)

W.D. Gaster, the Best Uncle Ever Part 2 (Chapter 2)

Elisa and Mona, Asriel and MK's "girlfriends," are back! :D But rather kissing Asriel and MK once more, the two little holographic monster girls themselves tickled them instead. And on their immensely ticklish feet of all places. ;) Well, that's what the two precious monster boys themselves get for constantly leaving their feet exposed. XD But Elisa and Mona leave their feet exposed all the time too! And as soon as Asriel and MK return the favor, it'll finally be time to play Gaster's game. And as for the game itself, think of it as "Undertale meets Dungeons and Dragons." ;)

W.D. GASTER, THE BEST "UNCLE" EVER PART 2

Chapter 2: The Game

Moments later...

Asriel: Alright, Uncle Gaster, I think MK and I are ready to play your game now. *said Asriel, he and MK standing up after enduring tickles to their feet from Elisa and Mona respectively*

Gaster: Hehehehe. Excellent, boys. Truly excellent. But before we start... would you be interested in getting some revenge on your little "girlfriends?" *asked Gaster in a cheeky manner, causing the four real kids to all perk up*

Frisk and Chara: (Oh my gosh, please let them! No tricks, Uncle Gaster!)

Asriel: Oh! W-w-well, as l-long as they're o-ok with us doing that. *answered Asriel in an excited but also shy manner*

Elisa: *gasp* Oh, my gosh, yes, please! *exclaimed Elisa excitedly all of a sudden, while lying down on the floor on her back* Heeheehee! Tickle me, Azzy! Do your worst! *she added, holding her bare fluffy feet up in the air and wiggling all six of her toes to tease Asriel until he started tickling her*

Asriel: Heeheehee! Well alrighty then...

Gaster: Hehehehe. Excellent... And what about you, MK? Would you like to tickle Mona?

MK: (Yes! A million times yes!) *exclaimed MK excitedly in his head, before calmly but shyly saying out loud,* Ehehehehehehe. Um, s-sure, Uncle Gaster... if... if she'll l-l-let me...

Mona: Heeheeheehee! Awww! Of course I'll let you, cutie pie! *cooed Mona, lying down on the floor on her back just like Elisa did moments ago* Heeheeheehee! Go on now. Tickle me. I'm reeeeeeeally ticklish. Especially on my feet! *she added, holding her bare scaly feet up in the air and wiggling all six of her toes to tease MK until he started tickling her* Heeheeheehee! Go on. Tickle me.

MK: (H-h-holy m-moly! M-Mona may not be real... but my love for her sure is!) YES, YOUR MAJESTY! *shouted MK both loudly and excitedly, despite the fact that he was literally standing right next to Mona XD* Eeep! S-sorry. *he then awkwardly apologized for shouting at someone that was in close proximity of him*

Mona: Heeheehee! Don't be, you silly. I think it's cute. X3 Just like how cute my sister and I are while we're being tickled...

Gaster: Hehehehehe. She's right, you know. So, boys, do yourself a favor and tickle these cuties. You have ninety seconds...

Once Asriel and MK were told that they only had ninety seconds to tickle their precious "girlfriends," the two boys themselves dropped right down to the floor and did exactly that. Asriel sat down right next to Elisa, wrapped his left arm around both of her ankles (which she crossed left over right moments before Asriel grabbed them), and scribbled his right hand fingers all over every insanely ticklish inch of her snow white soles. As for MK, he sat down next to Mona, wrapped his tail around both of her ankles (which she crossed right over left moments before MK grabbed them), and scribbled his left set of robotic fingers and right set of robotic fingers against her left sole and right sole respectively.
