At 6 p.m., a married man meets his married lover Yuki Yoshizawa for their monthly secret date after she lies about leaving on business. They avoid prying eyes with a drive, head straight to a hotel, drink, and rekindle their perfectly matched affair through two rounds of sex, with Yuki swallowing every load. After a midnight drive they check into a second hotel and fuck until morning, including creampies in a sultry costume, makeup-free blowjobs, and a short nap together. Though she sheds tears along the way, she asks for more morning sex and one final blowjob, swallows again, then changes into work clothes, kisses him goodbye, and leaves in the sunrise.
