Yuri, a 23-year-old working at an apparel shop, started coffee enemas after learning about them from coworkers, seeking better health and beauty. Having suffered from chronic constipation since childhood, she often struggled to enjoy sex, frequently needing to hold in gas. After beginning enemas, her intestinal health dramatically improved, leaving her feeling refreshed and comfortable every day. Satisfied with the results, she began extending the effects by continuing her daily routine for about an hour after each enema. One day, while reading a magazine during an enema, she suddenly felt a surge of arousal. Grabbing a vibrator, she rushed to the bathroom and began masturbating. Accustomed to the sensation of bowel movements, she casually used a fashion model in the magazine as her stimulus, starting her usual masturbation routine, gradually building up excitement as the scene unfolds.
