Teacher 'Jun', who is usually elegant, beautiful, and popular with her students, has a secret that I know! It turns out that she's a cosplayer who hosts photo shoots as a hobby! I called her over to my place after telling her this over the phone, and asked her to wear a perverted cosplay outfit in exchange for keeping it a secret... Even though she reluctantly changes, Teacher Jun teases me, whispering, "If you keep quiet, I'll do something nice for you," and seduces me in her raw cosplay outfit! I can't help but climax as I see her beautiful, pale skin perfectly complementing her perverted cosplay attire...
