This was asked by a femcel gooner sometimes maybe straight sisterlike friend of mine

This question is a bit silly, it's obviously impossible. The author might as well continue developing MDRG. You should let that woman find some alternatives, and if it really doesn't work, let AI help her.

Translation:
This question is kind of stupid.
Obviously it’s impossible.
The developer might as well stop developing MDRG and let you find a replacement for that girl instead.
If that doesn’t work, just use AI

If that ever happened, it would be interesting, but also very challenging.

Developers would need to create much more complex animations.
In Streams, the main character is the protagonist herself, not just a "sex bot", so animations would need to show both participants, not just one body part.

This would also require:

• More clothing variations

• Different body types

• More types of adult items (like strap-ons, etc.)

Additionally, there would need to be:

• More detailed animations for climaxes

• Features for things like physical needs (e.g., hydration during long streams)

• A system to track endurance, showing how much the character can handle without passing out

Overall, this would significantly increase the complexity of the game.

If Incontinent Cell creates a spin off, they wouldn't do the one you suggested.
