Aki loved her husband dearly, but she was unsatisfied with his size and her nightlife. The story begins when Aki's brother-in-law from the countryside comes to Tokyo to take a test. Her brother-in-law, who never gave up on his dreams, came to Tokyo. Unlike Aki, who was happy to reunite with her brother-in-law, her husband sulked due to his own insecurities. The next day, when Aki went to her brother-in-law's room, she saw him training in just his underwear and was shocked by what was bulging inside. It was completely different from her husband's! Unable to look away, Aki suddenly found herself lost in lewd fantasies... That night, Aki sneaked into her brother-in-law's bedroom to see it for herself. She quietly lifted the blanket and held her breath as she touched his. It naturally began to harden. Unable to resist, she tried to give him head, but it was too big to fit in her mouth. Excited, Aki ended up taking his load into her mouth and became lost in ecstasy.
