You might have read my post (nr. 1469) about the roadmap a couple pages ago. The Kati/Jamal side of the game is more geared towards fun, sharing, friendship, openness and consensual stuff. You certainly can get onto the hard NTR paths there, but the full romance and sharing/swinging paths are better IMO, because of the way they develop.
The full romance paths are wholesome and even there you can get some consensual naughty fun if you like. For example, an exhibitionistic Mei let´s Rashon watch even on total romance, because Mei and the MC discovered together that she is an exhbitionist at heart.
On the sharing/swinging paths we also can have a wholesome romance of Mei and MC, with the sharing/swinging developing step by step and consensual together. They can become a Stag/Vixen couple with Jamal (and Kati) a friendly boyfriend, Friend with benefits or simply a good fuckbuddy. They can become a Stag/Vixen couple which keeps some distance. They can become a couple which simply dabbles in sharing now and then or keep the sharing/swinging option open but not using it.
By the way, knowing some of your favourites, did you find the "teasing" subpath scene during the Rashon watching event? Should be right up your menu.
Naturally we can also get the harder NTR paths on the Kati/Jamal side, but I think we both are not fans of that stuff.
