A forbidden summer vacation for the uncle, a widowed single man, and his busty niece, Anzu, who has returned home from the city. In a secluded country house with no entertainment, her I-cup breasts are exposed and vulnerable... Anzu, while working on her graduation thesis, is bored and idly masturbating secretly yet boldly. Seeing her fall asleep with her nipples erect, her uncle is overcome with temptation.
"You touched my breasts, didn't you?" Anzu teases. "It's okay, as long as we don't have sex..." he replies with a cheap lie, then gently demands, "Touch them more..." "Come on, let's do it after all!"
In the bathroom, she aggressively asks, "Uncle, let's kiss," and engages in a perverse kiss, pouring saliva and drool into her open mouth. They gradually become more and more engrossed, their resistance disappearing as they have sex again and again. They change positions repeatedly, and he ejaculates inside her multiple times!
