DASD-506 Middle-aged uncle who does not know the sex of a literary man's daughter Rui Nanase

Nanase is a student who is studying hard as a student of mine. I'm not good at women, so I was attracted to her for some reason. I invited him to his house to show him some reference materials. Suddenly confessed by her at home, she couldn't hide her upset, and what she showed was a cock that grew from her lower body.
