“Senpai, let's have sex in secret.” Stunning new club member Iyona uses her devilish charm to wreck every relationship around her. Interested only in men who already belong to someone else, she captivates the entire club and secretly fucks them one by one in the restroom, clubroom, and even the men's bath. She does not care if her affairs are exposed—she will simply cum with another man. Once this small club falls into her trap, there is no going back.
