Any and all collaborations within Terra Trek is a collaboration to add your character into the larger cannon of the series. The series is a copyrighted work though you retain the right of the character. It's merely co-sharing if it is in universe and using concepts in it.

I am more than happy to collaborate and more with anyone but I do not do art for the fun of it for just the mere fact of having a cool collab or hot idea. The idea is throughout and takes about a day or more to finalize and integrate within cannon. This world took 6 years to make and you are only seeing the lewd side of a world built with the help of my friends in NASA, Multiple universities, and more. You get more of the vibe from Ao3 then anything about what this series is.

So if you do want something with Grover or whatever, then you must play the game. Otherwise the answer is no. I do this for my own soul and adding meaning. Each lewd as its own story below. If you care for that and like that and want something more from this, go on and dm me. Otherwise, with all due respect, I ain't interested.
