Summary
Once again I'm participating in the Rarepair New Year event, hosted by the wonderful Kamari!!!
As always, this is a collection of random ships and prompts/tropes, ranging from sweet SFW fluff to tasty NSFW smut. Expect a lot of Sanscest, but also some Papcest and cross-AU Fontcest. Individual ships and ratings can be found in each title.
I hope you'll like these little stories!

Summary
Red and Sans are polar opposites when it comes to sex, but they have found a dynamic that works for them: they alternate between slow, vanilla sex, and rough, BDSM sessions.
And today's a slow day. -

Summary
Edge and Red have reached a point in their lives as a couple where they want to start a family. Unfortunately for them, they're having a hard time conceiving. Fortunately for them, Red is undergoing a treatment to make him more fertile. Unfortunately for them, the treatment comes with... peculiar side effects. No bad per say, but definitely not appropriate for their current situation.
Stuck in a plane for another 5 hours, whatever shall they do~?

Summary
Snakehands: this is a bit of a game - Gaylie and Comic4244 have started this fanfic but they will not be the ones to finish it. Coming parts of the series will be written by different talented authors: Diyami, Soloshikigami, Hailsam, SansyFresh, Interverse, GetMcDunkedOn, Yastaghr and sin-cognito. Expect chapters and parts to have a different feel as each author has the freedom to write what they want and characters and parts may also seem a little different, but it's all part of the game.
