AKA-047 When a serious girl wakes up to her erotic side, things get serious. File.03 The first-ever capture of the drastic transformation and sex life of a pure and innocent beauty who is dedicated to her studies.

A beautiful 18-year-old girl named 'Ran-chan' attends a certain university. Raised under strict parents, her hobbies are reading and studying, making her a quiet person. Wanting to change her shy self and release her hidden sexual desires, she chose the path of AV performances. As her slender body is slowly toyed with, she gasps softly while looking down, using an unskilled tongue to suck on the penis. After experiencing the unusual space of a hapening bar and 'buccake' that she could never reach in daily life, she begins to show an expression filled with pleasure she has never had before.
