A forbidden summer vacation for her busty niece, Anzu, who has returned home from the city, and her uncle, who is living alone after his wife ran away. In a rural house with no entertainment options, her I-cup breasts are exposed... Anzu, too, is working on her graduation thesis and is bored to death, when she secretly and boldly masturbates. Her uncle is tempted by the sight of her falling asleep with her nipples still erect.
"You touched my boobs, didn't you?" Anzu provokes him. "It's okay, we just have to have sex..." she tells him a cheap lie, but then she gently demands his body, saying, "Touch me more..." and "Hey, let's do it!"
In the bathroom, she aggressively begs him to kiss her, pouring saliva and drool into his open mouth in a perverse kiss. Gradually, he becomes addicted, and no longer resists, as they copulate again and again. They change positions one after another, and cum inside him again and again!
