Hearing that his aunt Itsuki is staying overnight on a business trip to see how things are going, his nephew Toshiki is busy cleaning up his room. Itsuki, who I met for the first time in a long time, is the same as before, and she has changed even more beautifully, and Toshiki is nervous and can't make eye contact.

She notices it on the way, but her body that has already become sensitive accepts her pleasure.
