Some new things I planned to add into the next update.
Since Ahyana gradually became indulging in enemies' rape and lost to the obscene demon, Belva, the priestess of Exorcism Goddess has come to save Ahyana. Obviously, the enemies Belva will face are much more dangerous than those she encountered before, because they are now so skillful at sex assaults, thanks to the abundant mating experience with Ahyana. So the corruption on Belva will go much faster...
New game mechanics:
1. The preference of mating poses is now trainable. For example, if the count of choosing to endure pose A is a few more than that of B, the goddess will prefer pose A. And this preference can be reversed to preferring B if the count of enduring B is more.
2. The goddess levels up with killing skill while the enemies level up with sex skill. If the sex skill is high enough, an enemy can learn two skills that can make the goddess more submissive and lustful. One, the enemy can sense which mating pose is the goddess' fetish pose and will use that pose more often to make her more submissive and lustful. The other, the enemy can keep erection even after cumshot, and if the goddess' lust for this type of enemy is high, she will change into a more lustful pose after her submissiveness is full and the enemy still keeps erection (only Belva has the more lustful poses for the new version, Ahyana's will be added in the future).
3. The sexual desire now can affect the chance of escaping from being raped. So when the goddess' sexual desire has accumulated to high level, it will be very dangerous for her to go into a battle.
4. Other changes, like added in an 'wait and see' option during battle, which skips a turn (thanks for the suggestion from
@Darknessbeast), increasing mental power at the cost of increasing sexual desire as well; also found a way to lossless compress the images to half of their original size so the new version will be much smaller and easier to download.
