A man starts dating his childhood friend who is not beautiful but has a good personality. When they first start dating and he is at her house, her younger sister, Akari, comes home. He is surprised to see that she has grown into a much more beautiful woman than he expected, but he pretends to be calm and treats her like a child. Suddenly, Akari says, "I'm better at it than you," and makes him take off his pants, takes his dick deep in her throat and performs a deep throat blowjob. Unable to resist the pleasure, he shoots into her throat, drooling and cum gushing from her mouth!
