Concept...
boy turns 18, and celebrates the removal of online child controls in oasis with his online 'girlfriend', who is actually very wealthy, and indulges his minigts fantasy. this leads to several increasingly indulgent sexual escapades.
after a time, he want to know who she is in real life and starts to investigate. suddenly he finds himself cut off, and the deeper he digs, the darker his journey in oasis becomes. until he finally finds out she's a 58 year old woman who 'collects' oasis virgins
Story Arc...
open with him spending time with his online "steady girlfriend" for a casual hang... showing she's "cool", "likes to entertain", is a "gamer", likes to "dress nice for him", and seems more experienced than him
his online friends tease him about the 'big day', then taking him out on the town, and trying to convince him to go along with various schemes to celebrate... he declines, as he 'has something planned'. they joke that he acts like he has a "partner" and his response confirms it. then they tease him about how he's way too young to be paired up. he's just about to finally experience the real oasis, to experience anything he wants. they give him some oasis currency to splurge
he appears in the venue he shares with his online 'girlfriend'. she's in sexy but casual attire (pic pic pic). they embrace. she's knows what he's waiting for, comments about how he still has 3 minutes 40 seconds until he's 18. Teases him about gaming, going dancing, etc. etc. Finally she relents, and jests that it's not very much fun to seduce him when he's throwing himself at her. she invites him to meet her somewhere new. he can't go right away because it's age locked, so he has to wait until the timer expires. When it does, he's given a flurry of notifications about his new status, and congrats from friends. The Oasis explanation talks about removing modesty limits, and improved alteration options.
When he finally arrives at her new venue, she's looking incredibly sexy. (pic pic pic) She asks him what he thinks of her dress, joking that she tried to pick something sexy enough that he wouldn't want to immediately take it off. As she parades around him, he pops up an info panel about her appearance, and is enticed to a new set adult communication "pokes" (which he humorously tries out), and an adult 'alterations' panel he's never seen before. He asks about it, she explains that she gave him permissions on her avatar appearance, in case he wants to make any changes.
He opens the menu, and there are a myriad of "free" changes, hair color, hair style, skin tone, etc, then he reaches the body modification section, and everything is incredibly expensive. Every single change is two or three times more credits than he has in his entire wallet. "holy crap, why is everything so expensive?"
"Ohh, I'm sorry. That's the dress. It's from a famous designer, so any fitting change requires a designer up-charge for the dress alteration license. Here, let me give you some credits to play with." In a few moments, his wallet balance starts to twirl, and his jaw starts to drop as his balance skyrockets, first double, then ten times, then settles thirty times more than his original balance.
He coughs. "Holy crap. You just gave me XYZ credits."
"Yes. And?" She cuddles up to him. "We've been seeing each other for months. You could have gone out and let your friends take you to a cheap bit slave, but you told them no. You came to spend it with me, and that means something. I want you to really enjoy your first time, so go ahead, make whatever alteration you like."
He flips through the menu, his first instinct to puff up her chest to the kind of scandalous proportions sexy girls used in the social venues, but something stops him. This girl has class, and credits. She already had sexy cleavage popping out of her designer dress. What will she think of him if he puffs it up and makes her look tawdry and cheap. He feet on the spot, and tapped her taller. She had been a couple inches shorter in her four inch heels, but with a subtle gesture she was his height, then an inch taller.
