This game has lots of potential.
I'd say it's, at least for now, Karryn's Prison in Space. It has a silly plot, an absurdly curvaceous protagonist and some corruption. Sex scenes have a similar degree of interactivity, though so far you aren't stuck in any position (you can masturbate an enemy in one turn and do something completely unrelated the next, while Karryn would have to make that guy cum to "free" her hand).
The main differences seem to be that this game's system is simpler and the plot is sillier and more sex-friendly. Also, the FeMC from this game can flirt from the get-go and quickly unlocks handjobs and oral sex. Sexual minigames seem to be unlockable earlier, too.
Overall, it seems like a really fun game.
