Deciding to mess with some more stuff, you open the lactation menu. Women still lactate as a result of pregnancy, with their cup size growing as a result. Most men can induce lactation but as an extra effort.
You decide to change it to where women don't lactate at all and men begin lactating in puberty and will lactate until around 60. Upon pressing enter, you feel your breasts begin to fill up, inadvertently the change also seems to have increased your cup size. As you feel yourself fill up with milk you go check on your girlfriend. Shes laying on the couch on her phone, flipping through whatever social media has for her today. You sit opposite of her and begin to look through the other options at your disposal. With the new app you could probably change anything.
