In this adult family role-play, Kanon visits her uncle's Tokyo home during a long holiday and reunites with a cousin who is also staying there. No one paid much attention to her body in the past, but she has now grown voluptuous G-cup breasts. Despite their size, she goes braless, lets them bounce freely, and presses the soft tits against him at every opportunity. He struggles to contain his arousal—until Kanon takes the initiative and openly seduces him.
