Do porn stars really have any parents or family members who would care either way? Dad would seek out her daughter again to take advantage of the situation, and mom is too busy looking for husband #8.
That they have parents and people who care about them is a cinch. It's also a cinch that those people would see one gagging UPSIDEDOWN "blowjob" and ask "WHY WHY WHY WHY WHY?!!!!!!!!!!!"
