An innocent beautiful girl who is interested in kissing meets a middle-aged man and experiences a passionate French kiss. Although she is overwhelmed at first, she becomes addicted to tongue-to-tongue sex and even licking each other's dirty parts. They exchange sticky saliva, lick each other's faces, armpits, and anuses... They even lick the sweat that gushes out of her until her whole body is covered in soaked juices. She is enveloped in pleasure that melts even in her brain.
