Absolutely planned and getting familiar with Rey is part of the plot in part 1, but sexual interactions with him are unlikely to be in part 1 though.
The game will be split into parts, with part 1 being training Annie.
You play as Tony and the story of the game is basically going to be exactly the same as the comic's, just that Annie goes into heat earlier, just after Tony comes back to the court.
The main plot of the game will be to stop Annie from having sex with random boys by satisfying her in 'safe' ways. Part 1 will be taking place in between the day Tony returns to the court and the day he starts working with Kat on the sex bot.
Part 2 will be Kat, which will have some lewd Rey stuff planned.
Part 3 will be the double Annies, that's gonna have plenty of Rey.
Part 1 is the only one I'm guaranteed to make, though. Once I have a playable version of it I'll set up crowdfunding options and if those are successful, I'll move on to making parts 2 and 3 and on.
