Not an experience for everyone. A quick fap this game is not, it takes a lot of work to get the FMC to go slut. If played normally, this is one of the slowest burn h game, but also one of the best corruption stories.
The biggest draw here is that the gameplay/combat IS also the sex. You don't just lose and get an H scene, though there is that. While in combat, there are 2 ways to 'defeat' an enemy. Knock them out, or make them cum. There's an engrossing depth to strategically knocking out some enemies, and jerking off the remainder.
Or maybe you start off combat and dommy mommy force a dangerous inmate to cum with a blowjob once or twice, removing him from the battle and making the other enemies too horny to attack you and deplete your stamina. Once the dangerous enemy is out of the way but before you lose all your energy (which is another way to lose the fight), then you can kick the horny inmates in their erect cock for bonus damage, probably 1-shotting them.
Or maybe you go full slut and just decide to make all the enemies cum, but you still need to strategically manage your own horniness. If you have too many orgasms because Karryn developed a boob fetish quirk and the enemies keep attacking your nipples, you can deplete your energy and stamina faster than you can get off the enemies, and lose the fight. But maybe you have a passive that does bonus lust damage with your vagina, so if you can get the enemy's dicks in yours, and keep other enemies distracted with your hands, then you can out pace the lust they do to you and make them cum first.
Lose too many fights, and Karryn starts to develops so many passives that boost her horniness against her will that she can't control the pace of fights anymore, and you've effectively 'lost'. You can't fight the harder enemies because you're just too horny.
How's that for a battle system. Game is affectionately called, 'The Path of Exile of H games' with the large amount of passives and skills your character gets. I can't think of another game off hand where the actual sex is so integrally tied into the moment-to-moment gameplay. If you can then please let me know.
This bears repeating: Karryn goes full slut SLOWLY. Try to force it too fast and you'll find yourself unable to advance vs harder enemies. Controlled corruption is the name of the game.
