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.
Summary: 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.
Preface:
Chris' POV:
"Ugh." I groaned, as my alarm clock beeped annoyingly. "Five more minutes!"
However, as I had programmed the alarm clock to get keep increasing in volume until I forced myself to get up, it continued blaring. After a few minutes, I got sick of it, and got up to turn it off. After this, I quickly brushed my teeth and threw on my work clothes. I grabbed a muffin from the pantry and headed for the door. I entered my old, beat up SUV and put the key in the ignition. After a few key turns, the engine finally started up. Trying to ignore my frustration at the shitty car, I turned on the GPS and started driving towards work. When I arrived, I got out my ID and was soon permitted to enter the parking lot. I parked and got out, remembering to lock the car this time. I walked into the office, and sat at my desk.
"Let's see what's going on today." I said dejectedly.
Unfortunately, it seemed like nothing interesting was going on. The morning passed surprisingly quickly, and soon it was time for lunch. I was ready to head to the nearby McDonald's to grab some nuggets and fries. But before I had the opportunity to do so, I heard a strange noise coming from the confiscated anomalies room. Seeing as I was the only person that was not on their lunch break yet, I had no choice but to investigate. As I entered the room, the noise grew louder and louder, and I could even feel the room's floor vibrating. I soon spotted the strange item. Before I had a chance to analyze it, the item started quivering even more intensely, a portal opened up, and I was sucked into it…
