Interracial, gaijins/transfer students/expacs/etc, futa and strongly hentai-like debauchery (slightly Bible Black inspired)

So, I lately want to roleplay some partially interracial driven stuff and on the basis of the title, the basis of what culture is it or foreign country being Japan. This keeps happening incidentally as even just reference material as I sometimes keep landing on reference material of very anime or japanese like girls.

Also on the side, some futa and/or hentai-like debauchery., plus because I remembered Bible Black exists and it has a very distinct flavor for a hentai and its also just a blast from the past. Other than that, the kinks I'd like to play within this scenario is feminization, bustyboys, impreg, hyper (optional) and intersex/hermaphrodite males.

As for who I want to play on the basis of someone who is definitely not a native; someone of mixed heritage (African and Filipino/Pinoy), a nerd and somewhat a little on the thick/pudgy side (not only, say, someone in the 250 lb and 6 ft range) and if you want specific measurements for a visual? A chest of 47" (assuming near flat or flat), shoulder of 20", an inseam of 32", waist of 50" and hips of 54".

In simpler terms: someone who has a heavy bottom-weighted (and bottom-heavy!) build with an oval or pear-shaped silhouette.
