I case you're open for suggestions: Add that for all the girls players interact with (maybe as additional option to what they have already). Just guessing but various positions of vag vs dick intercourse is what most guys look forward too in H games (and loose interest in if getting literally dicked around). Have multiple option for them; otherwise they might get the "Oh, thats the bj
** only babe; hot bod but <skip>, boring; ah, next is footjob
** only babe... lol <skip>" label. The more each offers, the more players interact with them and thus your game. Your theme and visuals almost made me blindly just DL it; but reading that it has only one such interaction for now and thats planned to land in a few weeks puts it on a "check it out in 6 months again" timetable.
... on the off chance you already have all that in your plans forget I said anything
**not meant to shame, but to give examples. Replace with any lewd interaction you like or dislike.
