Not exactly futa on male but something of that sort maybe is in the works for next update. Artwork/animations are done just needs to be implemented.
Will there be actual futa-on-male at some point?
There is no plan for a futa on male at this point. But since you have mentioned this, having an alternate path to a scene with futa x male could be possible..(maybe it might cater to a wider set of audience) but I am not sure right now
