“I'm better than my brother, right?” When Ryu is assaulted in her sleep by her husband's younger brother, he uses the incident to keep demanding her body. She says no, but nipple sucking leaves her panties soaked. His relentless teasing draws out her moans before he penetrates her without a condom. His bigger cock reaches deeper than her husband's and makes her cum again and again. Soon she is begging for more, and he pounds her without restraint. By the end, all guilt is gone and Ryu asks her brother-in-law to cum deep inside her.
