Y/N POV

I was in my personal little vault, listening to the music player I had been taking REALLY good care of as it was one of the few things I had to keep myself occupied since even after god knows how many years have passed, I still had no idea how to open the door to the outdoors... Although frustrated about my circumstances, it could be much worse so I just continued singing and dancing with the music. While I was singing, I sensed another damn Radroach crawling around and towards me and my music player. Like an ambush predator, I waited patiently for the nuisance to strike by continuing to sing and pretending to be oblivious to its presence. Once it was ready to attack me, I just continued dancing because it's a fucking radioactively mutated cockroach whereas I'm the prime example of Charles Darwin's theory of evolution because of an experiment done on me by those bastards at Vault-Tec... now that I think about it... what happened to them? Last thing I remember was being dragged out of there while a soothing female voice kept telling me everything would be alright... that nobody would be able to hurt me again. She then said she'd be back very soon... but it's probably been years since that day. Once it launched itself towards me and my music player, I sent a small tendril through its body but since these vermin have been a constant nuisance for me, I didn't kill it immediately by consuming it but instead, I allowed the tendril to slowly replicate itself in the roach, causing it to wiggle and writhe in anguish as I watched with glee and the lyrical timing of the song playing couldn't have been fit my thoughts on the situation.

Y/N: *GIF Below* So put your hats on, Lohner don't get soft. You can see God, when I take my mask off~

As the replicating tendrils began to protrude out of the Radroach's body, I slowly allowed the tendrils to manually decompose and consume the biomass which would in turn produce nutrients for me. While I could eat regular human food, the biomass of living organisms provides significantly more nutrients than human food and it's much faster than eating... although eating regular food isn't as messy as consuming other organisms... especially when there's a lot of blood spilled... We Are by Hollywood Undead finished playing, I turned off the music player for the moment to go check on other things. However, while I had wandered off to check on said things, I felt something in my vault change... from what I sensed, the door had been opened! And... there was another living organism that had entered into my vault, but it wasn't an animal like a Radroach. Curious, I began walking towards the door while focusing on the strange organism's presence. I saw two female humans... which was strange since I only sensed one. However, upon quietly closed the distance, I saw that was actually an android as it or she had a tail and some metal for skin. Although I was taken aback by two beings that weren't Radroaches had gotten into here, not yo mention got the damn door open, I was more excited about the situation and went to introduce myself...

....

I PROBABLY should've taken a better approach to introducing myself...

Y/N: HELLO!

???: EEK!

Before I could do anything else, the girl quickly turned around and shot me in the face, causing me to fall to the ground. Although it hurt, I wasn't in any detrimental situation since my body immediately began healing the wound.

Y/N: Oww...

???: Oh! Oh shit! I didn't know you were a male! I'm so sorry! W-WAIT I SHOT YOU IN THE HEAD! H-HOW ARE YOU STILL ALIVE?!

Y/N: I'll uhh... I'll explain that soon. Just give me a moment to recover from the shot. Nice QuickDraw accuracy by the way.

Android: Non-Standard user t-template detected. Analyzing.

Y/N: Umm... An Android... *blushes* And with her boobs and crotch completely exposed, okay! Uhh...!

???: There's no way... you... you're actually a male? This has to be a trap. There's no way a guy would be left here alone...

Android: Analysis complete. This f-female suffers from a severe under-growth of breast tissue and chest hair overgrowth.

Y/N: Mmm~, not quite Android. I'm a male, since the day I was born...

???: Logic Error: User "$UNKNOWN" - UNAUTHORIZED ACCESS DETECTED .... Rebooting. Reboot completed. User $UNKNOWN" claims to be a male. As per core word information database, males are almost extinct. Analysis: User "$UNKNOWN" is now categorized as "High Risk" due to possible emotional trauma. Safe sex protocols operational.

Y/N: Umm... A Sex Android..??

???: Never seen a succubot before?

Y/N: Nope, but I'm more than healthy on every level.

???: Are you now? Then where are the people you should be with?

Y/N: Unfortunately, I've been here by myself ever since that door was sealed closed. Unfortunately, I've lost track of how long that's been... but if I were to guess... about 13 years, maybe 15.

???: The fuck? Then where the hell were you hiding all this time? Under a rock? No lies dude.

Y/N: More like trapped here... I haven't been able to get that damn door open ever since I tried to get out. How did YOU get it open?

???: Oh, Andrea unlocked it with her tail. There was a plug in on a hidden console...

Y/N: ... So that's why I wasn't able to open from here... Although I suppose I can now find a way to fix that... ANYWAYS! I'm Y/N. It's nice to meet you, Miss...~?

???: Uh? Oh! Names Trixie. Trixie Williams. Right, weren't you going to explain how you managed to survive a gunshot at point blank range to the head?

Y/N: Ah, yes! Right uhh... This might sound absolutely ridiculous but I can prove that I'm not lying if you wish

Trixie nodded her head slowly and so I began explaining everything I knew about my abilities I have through blacklight. Her facial expressions showed me that she while she found it absurd, she couldn't find any reason to accuse me of lying but then again I doubt she's seen a lot of people get shot and get up as if they had just slipped. Once I had finished explaining, she still looked speculative of everything.

Y/N: If you need more proof, I can show you something...

Trixie: Sure...

I nodded my head and took a few steps back.

Y/N: Here I go.

Trixie: Alright...

Once she said that, I began to morph my left arm into a razor sharp blade.

Trixie: OH JESUS! Shit! Okay!

Y/N: Cool or absolutely terrifying?

Trixie: I'd say both... But I—

I immediately grabbed her and Andrea and pushed them out of the way before slashing a much bigger Radroach in half.

Trixie: Shit. Thanks for that. So uhh... why didn't you kill us when I shot you in the head...?

Y/N: Well I did sneak up on you and scared you, although it was intentional. Still, shooting me seems like a completely reasonable response. Then there's also the fact that you two are the first people I've had as company since being left in this vault. In fact, I wouldn't mind if you both stayed here with me if you need some place to stay...

Trixie looked at Andrea and seemed to be pondering her options but I watched her lips curl into an alluring smirk.

Trixie: *VERY Flirty* Are there any fees or benefits we should be aware of~?

Y/N: *Smirks and equally flirty* Not sure yet~. I'm sure we'll figure something out~. I'll assume this means you'll be staying here?

Trixie: Sharing a place with a guy~? Hell yeah~!  Sounds like a great time, right Andrea~?

Andrea: I-Indeed~!

Y/N: Wonderful! Let's get you two settled in~.
