Boobs and Butts fanarts (Patreon)

The poll on the next 6fanarts was practically a draw, so I want to do both but the truth is that it would be a lot of work hahahaha, give me ideas on how we should proceed, so that it is fair and clear for everyone.

Let's suppose I do 3 and 3, so I should ask everyone a girl and I would choose who and from whom to make the butt and from which the boobs? I think that would be the simplest and most fair way, because if I ask you specifically for which butt and which boobs it could be very complicated.
