A long time ago, i played a somewhat of a brothel simulation game, it was 2dcg, female protagonist, i think it was build in RPGM, not quite sure but the way the character moves and the floot tiles and the z button to accept makes me think it was RPGM. The story basically goes where i have to sustain a brothel to make income so that i can pay this one dude from the mafia back (can't remember very well but it might be her dad), and in one scene if she couldnt pay back twice or something she was forced to get fucked and lose her virginity, and you can continue playing as her and can see the stomach develop into later stages of pregnancy, and i think u can prostitute yourself if you wanted to but typically not if you want a virgin run.
