Popular plump big-bottomed actress Suehiro Jun has sex with a black man for the first time in her life! Jun became a bar hostess at a young age. She has been married to her husband for three years, and he is very kind and a reliable partner at work, but he has premature ejaculation at night, which is not very satisfying and leaves her sexually frustrated. One day, some overseas baseball players come to Japan during the off-season. They mistakenly enter Jun's bar for one listed in the guidebook, but they like Jun's appearance and think they are lucky, so they stay and start sexually harassing her. Jun is confused when they directly appeal to her with their dicks, but because of her daily sexual frustration, she can't help but be curious about their crotches...
