This is a masterpiece of game play design, yet it does need some updates.
1. The main character is a psychologist? A master of the mind and body yet she does not have enough resistance for such enrollment in a practice? Why not give her traits that can be weaken over time! Similiar to a game called Game of Hearts!

I suggest incorporate 3 or 4 Areas that can be effected. Love, Corruption, Resistance , Depravity. When you finally manipulate the weakening of each trait, it releases a block scene and mini game for each one. This will give the game more depth and more alternate endings people will play over and over to try to achieve.
2. The main characters Husband. Give him at least a suspicion bar. Also make it available to convert him into what you want over time. by various actions. Via befriending him, setting him up with another women etc. means to gain his trust to simply in the end screw his wife.
3. The breaking down of Yuri was too fast! I don't know if you were short on time? and just wanted to push forward to the end result or not? but you could have introduced many mini games to weaken her ,similair to Shadows of Desire and the Massage room games and other mini games which makes it more fun. Also , have real alternate results via which path way of manipulation you use. I.E If you choose to keep "kissing her" then this will break her over time and thus enter into a different scene. Playing with her boobs only will do likewise but the scene will be generated around what part of the body you used which also will change the direction of the end path also. Each option has consequences and rewards. This is something I would add.
4. The Captured and about to happen Rape Scene. Why not give the other character options to not ! intervene until they feel like , thus watching what happens. From his point of view. Then give the asualters a seduction technique. Even though the event is horrible for the women, they can't help from having pleasure from it. thus in turn making the most horrible of events to happen to them pleasurable. js There is allot in that you can play with and add.
5. If you simply introduce some toggle mechanics in the game like Game Of Hearts, LOP. etc i believe you will give many what they always wanted in this Theme of a game play option. Somebody has to do it? Why not you? I mean you already have all the material and already began to make changes from the former engine version which thank goodness was done. I hope you consider making these changes and others.
6. Your other game with Cami is almost perfect in Shadows of Desire ,but I would make Fred have options of being stronger and more of a redemption path for him. Like have him go to a Gym option , building up his strength. have him gradually sleep with other characters or even escorts and when he does? His statues grow. His Penis actually gets larger , but not too much. Just balanced enough to increase his own self esteem and power. Give him that option to compete? would spice things up a bit as well. This does not have to change him from being some cockold version male but only 25% instead of 100%
Players might find that avenue more enjoyable, as well as making him some pathetic tool. You can even show Fred changing bit by bit, his morals begin to alter as he grows into the very thing he has dispised all along. Thus he begins to make other mens wives his sex slaves and as for their husbands , his own cuckold version shadows of himself. and he enjoys it! js.
