Adult PC Game: Footjob Girls! by Dryad's Forest Archive

There was once a Galapagos island nation called Jipang.
Here, young girls upheld a tradition called Ashikoki.
A school was established some 20 years ago to teach this custom to the young,
and the best of these girls would perform at a major national event. It was always Sakura's dream to become an Ashikoki Shojo, or Footjob Girl.
But, without a trainer she couldn't practice, nor could she appear in the event...... Sakura was sad. But fortune smiled on her when she met a man of dark hair
and certain talents in an alley near the train station. Yes, he was an Ashikoki Coach.
