体操服の女子大生がストラップオンで先生のケツ穴を犯し、弄ぶ

The teacher has hurt his back due to the college girl's martial arts and is taking a break in the nurse's office. The college girl comes in and makes a hole in the teacher's underwear, inserts her fingers into the teacher's anus and starts playing with it. The college girl inserts two, three more fingers into the teacher's anus, and says, "This is treatment, hehehe," and inserts a dildo.
