Miyu Sasaki, who lives in Kansai, goes on a date with her boyfriend in Tokyo. Because they're in a long-distance relationship, she's been abstinent every month! Even though her pussy is soaking wet during their date, she's too embarrassed to say anything. While she enjoys and feels happy spending time with him, a part of her can't help but think, "I just want to go to the hotel and get all tangled up, making out and fucking like crazy!!!" So, they eat and drink plenty during the day, hold hands, and kiss, and then at night, she lets loose and goes all out with sex! Her insatiable desire turns her into a sex monster, clinging to his perfect body and wanting more and more. Even when morning comes, she can't stop!
