Yuki is a legitimate beautiful girl who, while being embarrassed by her first perverted play, is gradually getting swept away as she's tied up and having her anus licked. Shinobu is a voluptuous bloomer-type beautiful flesh doll whose unhideable masochistic nature heats up the men's crotches and makes them feel unbearable. Riko is a licking-proficient young maid who is toyed with at the store, and her meticulously licking and serving the sweaty male body is charming. Hanae is a super-pure beautiful girl, but in contrast to her lovely appearance, she's a true masochist, and one can't help but be captivated by her drinking the man's semen. The charms each character possesses and the way they're drawn into their first experiences are the highlights to watch.
