NACR-318 A fair-skinned big-breasted girl from an art university, Seione Saira

I am a university art student named Sakura. My parents are designers at some apparel manufacturer. So I also want to pursue a career in design and am currently studying at an art university. But I'm not good at drawing male nudity, especially genitals, so I have him model for me, but he always comes onto me midway, making it impossible to practice. Frustrated, I consulted my father, but little did I expect it would turn into that...
