Undertale Tickle Stories (Main Series)

A "Humerus" Sleepover (Chapter 2)

Chapter 2 of this long story. In the previous chapter, M.K. and Frisk had one of their usual tickle fights. Except this time, things went differently. With help from his secret weapon, M.K. managed to beat Frisk for once. M.K.'s secret weapon is his tail, and he sure knows how to use it! :D Everything was going according to plan for M.K. until he was pulled away from Frisk by a tall, mysterious figure. Who is this mysterious figure, and what do they want?

A "HUMERUS" SLEEPOVER

Chapter 2: Frisk's "Great" Savior

M.K.: *gets grabbed by a mysterious figure* Woah! What the!

Upon closer inspection, the mysterious figure was revealed to be... PAPYRUS!!

Papyrus: Nyeh heh heh! Worry not Frisk! I, the Great Papyrus, am here to rescue you!

M.K.: *gulp*

Papyrus was holding M.K. next to his chest with his left arm and then not too long afterwards, he proceeded to tickle the lizard boy's belly with his gloved right hand.

Ever since Papyrus moved to the surface, he's been wearing his "battle body" much less often. Today, Papyrus is only wearing the gloves and boots from his "battle body," while the rest of his outfit is very casual.

M.K.: AHAHAHAHAHAAHAHAHHAHAAHAHAHAHAHA!!! PAHHAHAHAHAPYRUS!!! NOHOOHOHHHOOOHOHHHOHOO!!! AHAHAHAHAHAHAHAHAHAHAHAHAAHAHAHAHAHAA!!!

Frisk: Alright Papyrus!

M.K.: AHAHAHAHAHAHAHAHAHAHAHAHAHAAHAHAHAHAAHAHAHAHAHHAAAHAHAHA!!!

Papyrus: Vengeance tickles M.K.! Nyeh heh heh!

M.K. was caught completely off guard by Papyrus's surprise tickle attack and he spent the next few seconds laughing in a very silly manner because of it. As soon as Frisk recovered from M.K.'s crazy ticklish assault, she stepped in and tickled M.K. with Papyrus. And just in time too, because M.K. was trying to tickle Papyrus's spine with his tail!

Frisk: Oh no you don't, M.K.! *shouted Frisk as she grabbed M.K.'s ankles*

Frisk then wrapped her right arm around both of M.K's ankles and then used her left hand to tickle his feet. M.K. is now being held in an upright position.

M.K.: AAAHAHAHAHAHAHAHAHAHAHAAHAHAHHAHAAHAHAHAHAHAAHAA!!!! NOHOHOHOHHOOOHOOHOOOHOO!!!! DOHOHOHOHHOHOHON'T TIHIHHIHIHIHIHICKLE MY FEHEHHEHEHEHEHEHEHEEHEHEET!!!! AHHAHAHAHAHAHAHAAHAHAHAHAA!!!!

M.K. tried to use his tail to tickle Frisk, but having both his feet and belly tickled broke his concentration.

Frisk: You gotta watch M.K. Papyrus! He almost got your spine!

Papyrus: Is that so?

Frisk: Yes! He's become a real trickster during the past month! (A cute trickster, that is!)

Papyrus: Oh, well in that case, thank you for stopping him Frisk! That's my most ticklish spot!

Frisk: (Thanks for telling me.) *Frisk thought to herself mischievously*

Papyrus: We definitely wouldn't want him tickling me there!

Frisk: No we would not! (We would actually! Well, at least I would!) Hey, I've got an idea! How about we continue tickling M.K. on the couch!

Papyrus: A splendid idea Frisk!

With that said, Papyrus and Frisk walked over towards the couch while carrying M.K. in their arms. Both Papyrus and Frisk continued holding M.K. in an upright position while continuing to tickle him as they carried him over the couch. And as soon as they reached the couch, Papyrus stopped tickling M.K. so he could place him on the couch while Frisk continued her ticklish assault on his feet. A few seconds after that, Papyrus resumed tickling M.K. with Frisk. M.K. is now lying comfortably on the couch with Papyrus kneeling on the floor next to both him and the couch wiggling his fingers against tickling his sensitive upper body and Frisk sitting on the opposite end of the couch with his feet in her lap.
