Ryuji, who was a close friend of Kenji's when they were young, returns to Japan after a decade away from overseas.
Shocked by the change in him, Yuka starts drinking, and as Kenji passes out drunk, Ryuji shows her the size of his crotch and makes advances on her. 
Yuka feels bad for Kenji, but she can't firmly refuse. 
Dominated by the insertion of his huge cock, she screams in ecstasy, and even though she begs him to use a condom, she succumbs to the raw sex, and Ryuji, who has returned home, plunders her body.
