The Amazing Loud Watterson House (Featuring Rick Sanchez) - (Isekai)
5 parts Ongoing MatureSummary: Chris Luidolf has had a pretty awful life and is now suffering from severe depression. The only thing he has left is his job (investigating inter-dimensional anomalies). Try as he might, he seems unable to attain happiness. When all hope seems lost, Chris accidentally stumbles upon a strange device in the confiscated anomalies room at his work. He eventually figures out that the device lets him travel anywhere in the multiverse. Before he can contemplate the implications of this, however, the device starts making noise, and Chris is thrust into a different multiverse. The following is an account of how Chris and his newfound lovers (and their families and friends) found immortality, "immorality", happiness, etc.
Note for legal reasons: All characters are over the age of 16 (in-universe age of consent) when engaging in sexual activities. (the reason being that Rick developed a temporary age-increasing pill).
Credits: There are many fanfictions/fanarts/lore that I took inspiration from when writing this story. Some notable ones include "Rick and The Loud House" by Itsnouse95 and "A Loudcest Story" by Archemios. I especially used some of the ideas in the latter's story during the first chapter, however, since it is now no longer available online, I figured the general ideas in it were okay to use, provided I rephrased it into my own words, as well as crediting it here. Also of note is the TVTropes website, which I used to refresh my memory on the Sin Kids AU.
