They know that it would be a good idea, that if everything we did to Roushk when he was corrupted by the curse of lust would affect the time to have sex when he was back to normal. For instance:
-If we raise his libido in its corrupt form and force him to give us a blowjob, in the future when he is cured and he gives us a blowjob, he could comment that the taste of your penis is familiar to him and how much the more time passes the more he will become addicted to your penis he becomes to the point of putting it whole in his mouth to savor it completely commenting that he likes it
-If instead we choose to fuck Roushk's ass, when it is cured and we have to be the top he will react saying how the MC's cock fits perfectly in his ass and how he likes the sensation of your cock opening him while he also acts like a powerbottom bouncing on your dick
-And if we lose against him and he fucks us, when he is cured and it is our turn to be the bottom he could start slowly but the more time passes he goes wild, fucking us more aggressively while he could tell us some phrases that he said while he was corrupt
