Her husband was away on a business trip. Suzume decided to use an adult service for women for the first time to fill her loneliness. She booked a therapist who did not show their face. Suzume's heart pounded as she wondered who would come. What appeared before her was her sister's boyfriend... Both kept it a secret from her sister, but despite feeling guilty, they enjoyed the oil massage leading to genital stimulation, reminiscing about a woman. The first session ended without penetration. The next day and the day after that... Just thinking about him made Suzume's pussy throb uncontrollably. During the second session, she couldn't help but take in his huge cock and climaxed. After that, there was only falling and sinking.
