My name is Sakura and I am an art college student. My parents are designers for a certain apparel manufacturer. That's why I want to go into design and am studying at an art college. However, I'm not good at drawing naked men, especially genitals, so I ask my boyfriend to be my model, but he always makes advances on me in the middle of the act, so it's not good practice. I was at a loss, so I consulted my father, but I never expected it to turn out like that...
