A training diary between a man and a schoolgirl from compensated dating. Let me introduce my pet. Her name is "Kokoro," with a petite body standing at 149cm. Her small C-cup breasts are so sensitive that she climaxes just by being touched. I have been continuously administering tablets that I told her were aphrodisiacs to increase her sensitivity, along with brainwashing using a penlight. Today, I make her edge and hold back her orgasms repeatedly. Then, I call her friends over to join in and film an AV together.
