Ken sighed in his dingy little apartment. 20 years old, disowned by his family thanks to "The Incident", scrapping by barely on a minimum wage job, and basically has no social life... again thank to "The Incident". His life was basically over, and all he had for a little bit of entertainment was his old smartphone that was now on a really limited plan... not that anyone besides spam bots ever really called. He was cycling through Gacha games at the moment letting the initial burst of unlocking everything give him some amount of enjoyment before uninstalling and going onto the next. He had just deleted the last one, and then found our magical gacha game deep into the app store. He downloaded it and opening it he wasn't really greeted with a giant download page, a cutscene, or even an introductory tutorial. Just a plain menu with three buttons. "Pull: 1 available", "Characters: 0", and "Missions".
Ken wondered "The heck is this? Some sort of 0 budget new developer trying something? Well let's at least use the 1 free pull." to which he hit the pull button and there was no animation, but a simple screen that held two things. A "back button" and the portrait of a woman's face. A pale face wearing red glasses, and framed with long straight black hair. On the bottom right of the portrait were the four letters SSSR. Ken sighed and thought "Well that's the free max rate character... I guess I'll have to go to the Character menu to check her out..." although in reality he got incredibly lucky. Sure there was a weight on that first pull so it wouldn't be an R character, but it was still an extreme longshot for him to get an SSSR character. Still that didn't change the fact that Ken would then go to the character menu where he'd see her name "Megan Carland" and tap on her portrait. Her portrait grew in size and gave two options "Select" and "Cancel". He didn't get what he was selecting for, but as there wasn't anything else the man just hit the select button.
Ken staring at the screen didn't at first notice anything and then a deep female voice in her head asked "So how long are you going to be idling by?"
Ken spoke outloud in the same deep female voice "Who are you an- Huh?" Ken said really surprised at his voice, and then looked down at himself and saw that he was now wearing a suit that seemed to be containing a rather massive rack.
The voice in Ken's head said in a declaration "Hello, I am Megan Carland and you are currently in my body. As long as you are in me you'll have access to my personality here along with my expertise."
Ken said panicking "What's going on?!? How do I get my old body back?!?"
Megan's voice sighed and said "There is an option, but this is a great opportunity for the both of us. With my knowledge and qualifications I could get you a high paying position at most tech giants. I could help you create your own small business. You name it and I'll be able to do whatever you need as long as it isn't physically demanding."
"And what do you get in return?"
"Existence in the real world. I am but merely a character in your gacha game who can only exist while you use me. I hope to be of great service to you." Ken picked himself off the couch and went to his bathroom, and took off Megan's suit and stared a bit at her body as it was contained in some black lacy undergarments. Then wondered for a second whether or not, "Yes Ken, I am aware that you are ogling my body. If we're going through this mind if you let me take a bath?" Ken went to the bathtub to get the water running and then started going for the underwear as Megan said "Just let me do it. Relax and allow me to do my thing." Ken wasn't exactly sure what she meant but kinda just relaxed their body and then it started moving on it's own. Calmly taking off her underwear as the water of the bath filled.
Megan said "Great, feels nice to move my muscles. How about we continue our conversation in our mind?" At which point Megan enjoyed her time existing in a bath, and pleasuring herself and Ken while they talked about what they would do. Ken also decided whether or not he'd want to do the missions to get more bodies. Megan for sure was talented, but she also was a woman and he wasn't sure he wanted to gain all his successes through Megan.
