There is an optional netorare scene you can access with the black guy you meet in the town of wisdom by letting him borrow your girl if the nun is above lewdness of 50 there is a blowjob scene there supposed to be more with him like a sex scene the more you lent him the nun because the scenes are already in the game scene picture folder in theory but in reality it doesn't progress beyond the blowjob so I am not sure if the rest of the scenes are bugged or not implemented yet and there are so many bugs in the game its impossible to tell at this point if something is bugged or something is unfinished its really stressful.
I probably lent the nun to the black dude about 30+ times raking in so much cash and it still doesnt progress beyond her giving him a blowjob I just gave up/, im not sure if anybody has been able to get past that but the game needs some serious work otherwise its just a buggy mess and its extremely stressful to play.
