Two things, one likely an oversight. When you start the game it says "target this one, the others will lower the lewd juice" because that's the way it was. However, with update #3 there's now two babes you can get at a level that will increase the lewd juice, but the info to start still says one only.
The other...there's supposedly 15 levels but the game stops after you humiliate the "spoiler" at level 10. After levels 11-15 still in development, is it a patreon-exclusive thing, or what? Really love the update and def worth the purchase!
