Tom and Lola go to the house of their doctor where they meet other children. 2 girls (5 and 10) and a boy (11) seem to be "at home" nudists; they at least sleep in the nude and seem to usually go around the house with nothing on. Children play with sprinkler, then they go to sleep.
Later he has nightmares about the ordeal, but the dreams get infused with visions of himself naked on top of his naked mother, including grinding, touching and kissing.
