The editorial department received a letter from a user who is an ardent Senbile fan. So, they decided to have Tsumura-san and Nakazono-san, two women with 100cm I-cup busts, make a surprise visit to the site. The user, unable to hide his surprise, gradually became unable to withstand their provocations and fought back with naked desire. And in the end, it developed into a massive orgy with five people mixed together.
