It doesn't really matter. Also that gif is disregarding most of my message. Also ITS A SEX ROBOT. A MODULAR. SEX. ROBOT.
Well, in that case. If you like "a lot of things".
You should play "The Sims 3 or The Sims 4" with mods.
You can freely customize your character and your sex partner however you like, and with mods, the possibilities are endless.
The Sims 3 &4 have lots of NSFW & Sex mods that you can download from the internet.
Your partner can be anything.
A Futa, a Femboy, a Tomboy, a Gay person, a Lesbian, a Furry, an Orc, a Goblin, etc.
Your partner can have massive breasts with a penis, just like what you desire~
You can have sex with her or him in any poses and with any fetishes as well.
It's up to you whether you can find the mod that suits your needs or not.
Or you could try "Koikatsu, Honey Select, Virt a Mate, or Skyrim".
These games can satisfy your sexual desires with mods. Fully customizable character, endless possibilities, many fetishes, and sex positions.
But if you'd like the developers to listen to your requests and implement those things into the game.
You can do that by becoming a member on either Patreon or SubscribeStar, then look for a voting poll, and then vote for things that you want to be implemented into the game.
After you become a member, you only have to wait and keep supporting the game for a few months or years, and when it is time, the developers will implement the winning vote to the game, just like how the shower scenes are going to get implemented into the game in the next big update.
This game currently does not support modding that can exceed her current chest size.
It’s not a matter of “just update and make them bigger.” For the developers to add something like a breast enlargement module, they would need to:
- Completely redesign her body mesh.
- Create an entirely new rigging system for animations.
- Adjust or redraw every outfit individually to fit the new shape.
- Rebuild all interactive animations to work with the new size (arms movement, touching, sex scenes, etc.)
And with such a tiny dev team, that’s easily a full year of work or more just for a single visual change.
People have already tried to mod her chest size, and they all failed and gave up.
Why? Because the game isn’t built for flexible body customization like that.
It’s simply not possible without access to the original rigging and systems, which only the developers have.
You’re not just asking for a “simple update”, you’re asking for a complete redesign of the game’s core structure.
I'm sorry, but something like this is currently not possible. 
And here's your "Futanari Mod".
