Rika, who had just moved in to live with her boyfriend, fell off a ladder and hurt her lower back. Makoto remembered that he had introduced the chiropractor Ito to a real estate agent, so he contacted him and arranged for him to come to his home. Since it was his boyfriend's introduction, Rika felt at ease receiving the treatment, but he touched her sensitive private parts too much, and although she tried to hold back, she writhed in pleasure. The next day, Ito treated her again, and when he touched her private parts, her desire was on the verge of exploding! The timer went off, but she instinctively asked for an extension.
