Since there aren't many games that feature it(that are available for mobile), Can you add a new hermaphrodite start? You'll still be able to get knocked up, but new content can be added that allows the player to knock up others. Or at the very least, be able to turn the upcoming femboy into your own cumdump. Why the specification of your own? Because I suspect that even while not being a futanari, the MC will most likely be able to "corrupt" the "straight" roommate into become a cumdump to the fathers of her children when she's not in the mood.
