身体柔软、心纯粹的文科大学妹子：让我的继父为我做一个裸体模特，他很兴奋

My name is Ririka, and I am an art student. For a school assignment, I was supposed to do a drawing of a naked man, so I asked my boyfriend to be the model. But, halfway through the assignment, it just working out with him. As I was worrying about what to do, he said, "If that's the case, my father will help you"! So we asked him to do it and he agreed. But, when he finally got naked, he had a huge cock!
