It’s not icky in a bad way. I mean, I made a challenge about incest. It was good, and you should’ve entered it. It was implied to have an incestuous act.
hahaha! Dad has been philandering! I guess you could say half-sister, and if it were in a case like my husband’s where his half sister shares no resemblance whatsoever, nor even a last name, completely plausible. :)
