Nanako and Kaoru: We're Falling Into Depravity

You're so cute, Nana… Can you see where we're connected? He asked while penetrating deep and stirring me up. He's making me go crazy, giving me orgasm after orgasm as if trying to make up for the lost time...! Nanako is temporarily living with her cousin, who is 13 years younger than her. Although she was concerned about that time he looked at her with the eyes of a man, it's been five years since, so there should be no reason to be afraid of her cousin... But as they end up sharing a bed, he masturbates while calling her name every night!? "I love you. I've loved you since I was a kid..." As he lusts after me with those same eyes, I'm not able to deny him this time... With his endless caressing and the intensity of his deep thrusts, guilt gives way to pleasure. Is this sweet obscenity a punishment for running away back then?
