Well, that was a surprising amount of fun! Cast is nearly as swollen as the MC's bits, though, so it may take a bit to keep track of all of the zany going on. Though with the amount of polish and effort presented it sure does look like there's a solid plan already mid motion, so maybe it won't be so overwhelming after all.
Quite a bit of flavor with the dialogue which is always a plus.
If I were to make utterly shameless suggestions and whatnot I'd go with something along the lines of:
The scene in the lab was some saucy good fun, and I can only hope at some point the MC can get just as wrecked as her best friend was. The sticky situation was quite a sight, after all. Though to be fair I'm usually in the minority of being in favor of the MC getting as good as they were giving.
I found the mom to actually be quite wonderful and endearing in her own way. I for one welcome our alien futa overlords and would humbly suggest the mom also get blessed with the same equipment as the MC, thus *max* kink can be aquired. Especially with her popping a boner remark. But you did a fine job of making many of the cast feel likeable despite the short introductions, so it's worth mentioning.
On the topic of weird kinks that fit-- Lucas and his constant barrage of feline vid messages. If DM-to-be Lucas doesn't end up as a catgirl it will be a remarkable waste of irony and amusement, and thus I shall be the sad.
You have quite the creation in the works, and I am super curious to see what comes of it. Good luck!
