Click on Artist (top right) aka Holiday Yasumi. The Father and Daughter Story (white paper?). Has multiple father daughter stories. The very last Arc are these two characters who start a sexual relationship in the bathroom and eventually go to a hotel together to have sex for first time. Both incidents mentioned in this After Story. Enjoy~
