Aika's husband has been busy with work lately, so he no longer pays much attention to her. The neighborhood association often organizes camping trips, with mostly middle-aged men attending. Aika's husband signed up to participate, but due to his busy schedule, he had to ask Aika to go in his place. Feeling down about her family issues, Aika ended up drinking too much alcohol in nature. Taking advantage of the situation, the head of the neighborhood association made advances towards Aika's beautiful body. Despite verbally refusing, Aika's body betrayed her by repeatedly reaching climax. Knowing that Aika was lacking sexual satisfaction, that night the association head continued to the tent to seduce her. And this time he succeeded. Since then, Aika has noticed changes in her body. She only feels pleasure when having sex with the middle-aged men. Now, she not only doesn't hate camping trips, but looks forward to them even more. Even when her husband wants to go with her, Aika adamantly refuses, wanting to enjoy the sexual pleasure with the middle-aged men alone...
