Hmm, found a slightly beneficial bug- during the tutorial, if you click "Prev" instead of the first time the "Next" button changes to "Close", you can keep going beyond where the tutorial would tell you to end early. You can't touch or do anal, just sex, and can use auto. If she reaches 0 stamina it'll softlock, though.
Also if anyone else is confused by the teasing events, you gotta do the other 2 objectives first, the 12 orgasms and lv6 vag/anal.
