A naked tutor

The highly popular S1 nude series is the third installment! My father applied for a private tutor. Apparently they incorporate a completely naked teaching method, and when they arrive at the house, they are completely naked at the entrance and come to my room. Of course, a female teacher. I and my father are captivated by the beautiful tutor who smiles with a smile even though he's on the slap, but are captivated by the naked Katekyo Ayumi...
