Despitthe problems I have some suggestions:
-Make more discipline methods
-more clothing and accessories
-option to make then to stay nude (discipline or preference)
-remove or mix clothing parts (shoes, top, bottom, etc)
-more poses (doggy, titjob, footjob, gangbang, handjob on oral, cowgirl,etc)
-option to slap during oral (you can only slap when they stop)
-option to slap ass during training
-different girls enjoy different things (example: the first blond girl dislikes vaginal but likes blowjob, or other girl might like anal but dislike oral)
