shitty game, The wife route(pink hair), you cheat on her, she has affair with some dude or sponsor w/e, and you get back together, gets pregnant (idk if the kid is yours or not), the wife's sister route(blue hair) you cheat on ur wife repeatedly, leave her, marries her sister. Threesome end, wife snaps, you do humiliation play on the two, boom both are pregnant.
