Aki loves her husband, but the size of his penis is unsatisfactory and she is not satisfied with her night life. - The story begins when my brother-in-law comes to Tokyo from the countryside to take a protest test. - My brother-in-law, who never gives up on his dreams and does his best, came to Tokyo. - Unlike Aki, who is happy to be reunited with her brother-in-law, her husband is depressed due to his own complex. - The next day, Aki went to her brother-in-law's room and was surprised to see him training in just his pants, and how he was making a statement inside his pants. - It was a big difference in size from my husband! - Aki, who was staring at him, suddenly had a lewd fantasy... That night, Aki sneaked into her brother-in-law's bedroom. - To see it with my own eyes. - I quietly turned over the futon and touched my brother-in-law's penis while taking a deep breath. - It naturally erects. - I can't help but try to give him a blowjob, but it's too big for me to fit. - Excited, Aki takes the cloudy liquid in her mouth and becomes mesmerized.
