MXGS-1136 We have a naughty relationship without telling our girlfriend, and my girlfriend's younger sister who seduces me is a cute female student, Ichika Kasagi.

Naichika is an honor student and quiet, but she actually loves naughty things. - The man she fell in love with was her sister's boyfriend... - She was alone with him on the day before her entrance exam the day after tomorrow, and finally seduced him... - Her eroticism that approaches you with sweet and polite language from beginning to end is a must-see.
