The first best of Sachiko-chan, a girl with natural huge breasts who looks good in glasses, and a J-cup idol with over 100cm breasts, is here! A schoolgirl who begs for creampie on an affair trip with her teacher, a geeky female college student who becomes addicted to sex for the first time and becomes a dick-loving woman, and a naughty office lady who looks pure but has all her coworkers as sex friends. This is a must-have album for fans that contains all of Sachiko-chan's charms!
