A prestigious girls' school with rumours that the school rules and dormitory life are extremely strict. In the girls' dormitory of such a school, they fuck in a chain from morning to night! The best part of this work is... they're fucking for more than 90% of the recording time! Seven female students are doing it! Maybe it's because they're forced to live a disciplined life, but as a reaction, they're addicted to sex! They want to fuck whenever they have a dick! Sometimes they don't care if they engage in a little lesbian act with other girls! They look serious on the outside! They're sluts on the inside!
