My nephew, Yuichi, who decided to stay at his uncle's house for a while for job hunting. Her heart beats fast to her beautiful young aunt. Although she was relieved to be accepted by her kind uncle and his wife, she couldn't sleep easily either because of the change in her environment or because she remembered her aunt. She tries to relieve her frustration with masturbation, but unfortunately her aunt walks in. Yuuichi panicked. However, her aunt smiled gently at Yuichi and let her touch her chest, saying, "Don't tell anyone ...".
