A ridiculously large buttocks and waist... A newlywed wife whose training posture drives rationality mad. Muscle training and sweaty ejaculation in the gym, an illicit affair. Wakatsuki Iroha GOUL-015

Iroha is newly married. After registering her marriage and moving in with her husband, her weight begins to increase... She wants to lose weight and get back to her former figure before the wedding, so she starts going to her private gym three times a week. The trainer is gradually attracted to her beautiful figure and the sexiness of a married woman, while Iroha is attracted to his muscular physique. Before they know it, they begin to admire each other and forget about training. Things get more and more intense, and Iroha calls in another trainer, preparing for a threesome "sex feast" of muscle-bound lovemaking.
