The mysterious sweet

Blue eats a tiny sweet with BIG consequences

“Here” nightmare said while handing blue the sweet “what’s this?” Blue asked “it’s a magic sweet that can increase you attack power” blues eyes lit up “really?! Wowie!” Blue ate the sweet instantly “yum, what happens now?” “Don’t worry, you’ll know when it starts” nightmare quickly left the room.

Blue began to feel his ecto body start to form, all around his body, blue was slightly confused after he heard his stomach grumbling “that’s odd, I don’t think my ecto tummy’s ever grumbled before”

Suddenly blue began to feel bloated, he looked down and saw his belly start to expand “W-what the?” Soon his shirt began to roll up his body as his bright blue ecto tummy started showing, blue tried to pull his shirt back down, but it wouldn’t go over his stomach.

Blue started to feel his legs get wider, his thighs stretched against his shorts “W-whats happening to me?” Blue asked as his arms started to expand, his shirt was now only covering down to his chest, which began to droop down and form moobs, his belt snapped off and fell on the floor “h-help! Someone help!”

Blues shirt sleeves ripped off from the size of his arms, his body got so big his moobs were now exposed and the entire shirt was ripped off from his body and fell on the floor, leaving blue topless, he saw a glow emitted from his tummy “h-how do I make it stop?! H-help me!”

His shorts began to dig into his thighs, he hoped that they would stay on, but at that moment, they started to rip, it traveled up his legs until it reached the waistband, it snapped off, leaving blue in his underwear.

“S-someone help! HELP!” Blue screamed as his underwear stretched out to its capacity, it snapped off, causing blues belly to droop down, jiggling when it bounced, thankfully it covered his junk.

When his body finally stopped expanding, blue looked at himself, he had rolls everywhere, along his back, belly, legs and arms “is it…is it over?”

When blue thought it was over, the blue glow returned to his belly, this time he felt a small vibration in his stomach, then it started jiggling “W-whats happening to my b-belly?!” Blue asked as the jiggling got faster, he started to sweat when the jiggling spread up to his moobs and thighs.

“W-why won’t it stop?!” Blue asked as he felt his arms and then his cheeks start to jiggle, as the blue glow got brighter, the jiggling got faster and faster throughout his entire body, the glow got too bright for him to see, blue closed his eyes and screamed as his body jiggled as fast as it could, making him stagger slightly “W-what’s…happening…to…meeeeeee!”

“AAHHH!” Blue screamed as he sat up on his bed, sweat running down his skull, he quickly looked at his surroundings, he was in his bedroom, blue pulled off the covers and looked at himself, he was relieved to find out that his ecto body wasn’t summoned “oh it was j-just a nightmare, heheh” blue quickly went back to sleep.

(My first ever undertum story, I hope you enjoyed it)

[skele-tums]

Might make some undertum stories here.

[skele-tums]

Didn’t there used to be a discord for undertum?…or was I too late and missed the party?

[skele-tums]

It was one of his favourite shirts.

[skele-tums]

Fell caught you staring as his big ol’ booty. I think he might need some new clothes.

[skele-tums]

I guess everything jiggles, or this could be his tummy’s way of saying it’s hungry.

[skele-tums]

Underswap papyrus with a cute little beer belly. And of course he’s drunk.

So I figured I’d spill my secret and tell you how I draw all these big bellied skeletons.

I start by drawing in a couple circles until it’s a decent size and shape, then I draw from his cheek to the curl at the back of his head, after that I just connect the ends with a smooth round noggin.

After drawing over the head shape in ink I rub out the pencil with a rubber, then I make a few attempts at drawing the shape of the body, starting with the moobs, and then I draw a round belly line from one to the other, and of course he’s gotta have that belly button.

After that I work on the legs and arms, if you look at the left arm you’ll see different vertical lines I’ve drawn in, I do that whenever I draw multiple arm styles to mark down the one that I’ll draw over with a pen.

Once that’s done I move back to the face, this is when I decide what sans to do, I decided to go with dream, because I haven’t drawn him yet. After drawing the crown on his head I work on the face, obviously I keep that iconic sans smile, I want the expression to be in the eyes.

Once I’m happy with the face, I obviously draw over it with ink, colour the eyes and nose, and draw on his teeth, I used a yellow pencil crayon on his cheeks to give him a blush, and I went over it with lines of yellow ink to make them stand out.

The rest is simple, I give him some nipples and colour everything in, then I put my signature down and then I’m finished. That’s how I draw.

I think horror needs a little help.

[skele-tums]

Fell trying on a corset to see what he’d look like if he was skinny, but he obviously didn’t think about the consequences, but at least it looks like his moobs became breasts 😂

Here’s my lil headcanon for underswap sans, he loves it when you rub his tummy, papyrus usually gives him belly rubs when blue has a tummy ache, but he loves them either way. Also I really need to get better at drawing hands.

Sans taking a well deserved nap after a long meal

[skele-tums]

Horrors clothes about to rip due to his size

[skele-tums]

Blue seems to have eaten something funny, and now his body can’t stop growing.

[skele-tums]

Just ut sans and error embracing their jiggling bellies.

[skele-tums]

Nightmare being a little embarrassed about his body, but dream usually encourages him to embrace his chubby body.

Sans getting stuck in a shortcut.
