Summary
Requests: "So I always love just how intense a sub you write Swapfell Papyrus. It gives me life. Based on the public ask could i request some of those scenarios such as him actually giving oral in a restaurant under the table and him with a vibrator stuck in him in public?"
"Would SF Paps be OK with his S/O tying loads of vibrators to him and edging him in public? If so what would it be like"
"I love submissive sf papyrus so could I ask for him being teased in public, like not full blown sex but secret touches and whispers that get him worked up and desperate but he has to wait to be allowed to go home for sex"

Summary
For the longest time, this universe could only experience two timelines, bouncing back and forth between them with each Reset. But then one day, a human appeared at the end of a timeline. A skeleton then told her to "press the button" because this timeline was already ending differently, so why the hell not?

Giantess Lammy X Parappa: Big-Step-Sisterly Fuckery (parody of Giantess Toriel X Asriel: Motherly Fuckery) by xandermartin98
Fandoms: Um Jammer Lammy, PaRappa the Rapper, Undertale (Video Game)
20 Feb 2017
Tags
Summary
In what can only be described as the Parappa The Rapper equivalent to the infamous Giantess Toriel X Asriel: Motherly Fuckery fanfic from the Undertale fandom, Parappa one day finds out, in an urgent phone call from Chop Chop Master Onion, that Katy and Lammy (his big stepsister in this story) have drunkenly fallen asleep together in the Milkcan concert auditorium...and also that the legendary master himself has sent the incredibly dirty-minded Paul Chuck and Prince Fleaswallow as bodyguards...and also that he has a shrink gun.
What ends up happening from there is anyone's guess (wee, at least, anyone who hasn't read the original Motherly Fuckery before, that is), but what I definitely CAN tell you is that it makes the original MF look absolutely TAME by comparison.
Have FUN, motherfuckers!

I am incapable of writing drabbles. This was SUPPOSED to be a VERY short little thing based on @dirtytoxin’s post where Sans develops a fascination for pillows. If you haven’t seen it, go look through it quick and then come back: https://www.pillowfort.io/posts/36942
HOLY HELL YOU ALL LIKE PILLOWS. OK THEN, I SEE A SEQUEL IS NEEDED. GOTCHA...

Summary
This is in response to the Screepy Valentine's Challenge by PancakeUniverse/PancakePants! https://agraulisvanillae.tumblr.com/post/155354176272/screepy-valentines-masterpost
This challenge includes first Gaster/Reader, and will be updated soon to include Muffet/Reader! The point is that the pairing is both sexy, and a little creepy, it can't be noncon but you do kind of wonder what you're doing, with both your partner and your life.
