Brian, even more than Rachel, was still feeling shame at being naked in a tub with the others. So he sat quietly, covering up his pee-pee as best he could. He had been cringing as his Mama cleaned it right in front of Rachel and now he just wanted a diaper on so he could hide his shame.
After allowing the babies some time for play, and once the floor of the bathroom was sufficiently soaked, the mothers stepped in to bathe the kids. Brian and Rachel tried to be cooperative so that it would be over faster. When Sara told them to lie on their fronts so she could clean their bums, they did as they were told. Only when they saw the flash did they realise she was actually snapping photos of the four young people lined up in the tub with their bare bums pressed hip to hip against each other and presented to the camera.
