Today's health and physical education class was different from usual. Boys and girls took off their clothes and touched and licked each other's genitals to confirm the differences in their bodies.

The boys, who were in the prime of puberty, were licked, touched, and played with all over their bodies, and the girls' sense of shame only increased.
