Based on the phrasing, Uncle meets niece after a long time and having returned to the countryside, she is still oblivious to the adult world and is probably pre-adult or just at the 16 or 18 year old mark as her body has clearly fully developed already, multiple sex scenes, didn’t have to time to watch it all but wanted to leave a semi-review, so overall for the scenes which I think there were 5, I give it a 7/10, for a motion anime it’s definitely up there for good ones
