Aika's husband has been busy with work lately and no longer pays much attention to her. The neighborhood community often organizes camping trips, with the majority of attendees being middle-aged men. Aika's husband signed up to participate, but due to his busy schedule, he had to ask Aika to help him out. Feeling upset about her family issues, and with the opportunity to drink alcohol in nature, Aika ended up drinking too much. Taking advantage of this, the community leader made advances towards Aika's beautiful body. Despite verbally saying no, Aika's body betrayed her by reaching climax repeatedly. Knowing that Aika was lacking in sexual fulfillment, that night the community leader went to Aika's tent to seduce her. And this time, he succeeded. Since then, Aika has realized that her body is gradually changing. She only feels pleasure when having sex with the middle-aged men. Now, not only does she not despise the camping trips, but she looks forward to them even more. Even when her husband wants to go with her, Aika adamantly refuses, wanting to go alone to enjoy the sexual pleasure with the middle-aged men there...
