Today I have encountered something upmost interesting: I have a family in which the head of family is of a shady evil branched criminal, a mafia boss. Yet his daughter, a young adult, is a good girl who wishes nothing to do with her "family business".
She carries many good traits such as Good, Hardworking, etc Her life time wish is to be a surgeon, saving people perhaps victims of her father's syndicate. Ok enough with the fancy intro.
I decided to add a bodyguard for a family so I made a male sim who is Brave, Loner, etc He is supposed to stay home all day until I can figure out how to make him driving people around.
He had a few chances to socialize positively with the mafia daughter, although no where close to romance yet. I say what the heck, try making them to woohoo. The daughter was relaxing on her double bed watching TV, Mr. So I made him "relax" on her bed to watch TV and chat as well. He didn't seem to reject.
While both relaxing on bed, the Woohoo option appeared, so I thought I would try, knowing for sure either one would refuse. Strangely, they went on with it! Yet, they did not become love interest: They shoo each other out. Yet, when I replicated the steps to make them woohoo, they still went through with it while remaining friends.
I have awesome mod only. Neither of these sims carry any trait remotely relevant to be a flirty swinger. Well, the girl has Hopeless Romantic, if that is close. Yet, they don't mind Woohoo one bit. I just hope they don't do it on their own and get a baby.
Luckily I play with Story Progression off, or else it would explain why some players keep complaining they do not know where some babies came from or their biological fathers. I work for a living, but I don't necessarily live for a working.
