Maybe more feminization themes? I like the idea of the mc being feminized into more of a femboy as he becomes more addicted to futas.
Also, possibly later on making more routes for mc being the top instead. For example, I want to take the coworker down for screwing the mc over. Possibly mutual destruction as well or instead? So instead of the top route if it's not inline with what you want the theme of the game to be, maybe give a choice later on to make her addicted to futa cock as well? Even though I love futadom, it's the pettiness in me that wants to see her taken down as well for drugging the mc. Ig I've always been more of a fan of willing bottoms than being coerced.
