With a non-professional girl who was picked up, confirm their parental love and have them rub each other's crotches with a single piece of 'melting' lube. This time, the obscenity level is increased with 'melting' lube! If it feels moisture and melts to create a hole=if there's a hole, it means the girl's pussy is wet from her father's stimulation. Even though they're parent and child, everyone is soaked.
