A documentary on a sex meetup organized via social media, inviting married women trying to conceive, with the invitation stating, "Since my husband is blood type A, I'm okay with creampie from an A-type man." This time, 25-year-old Aian, a beautiful woman with a fresh, cheerful appearance, takes part. She's had three affairs, has a strong desire for sex, and has a secret perverted side—whenever she meets a muscular, tough man, she can't help but grin mischievously. A two-day, one-night sex party unfolds, fueled by aphrodisiacs and alcohol.
