Panty shots and breast shots have become commonplace, but in recent years, belly button shots have been in the spotlight as a form of everyday voyeurism. This film is an ambitious work that focuses on girls' belly buttons. After carefully observing the shy girl's belly button, he drips saliva onto it, sucks and licks it. He presses his erect penis against it as if doing a thighjob, and finally ejaculates into the exposed belly button. In a sense, the belly button is a sexual organ.
