My name is Miyu, a student at an art university. This time, I have an assignment to draw a male nude, and I asked him to model for me. However, he started making advances halfway through, causing the assignment to stall... Feeling troubled, I mentioned this to my grandfather, who said, "If that's all, let your old man help out!" So I asked him, but once my grandfather stripped down, well, he was quite vigorous there...
