Her sister-in-law, Shinna (Nina), who was born after her father remarried, was a "black gal big breasted JK". I'm doing black gal erotic doujin drawings (*hard erotic), and I masturbated with my younger sister, and when I drew a manga based on my sister.

My sister-in-law, Shinna (Nina), who was born after my father remarried, was a "black gal busty JK". After Shinna-chan found out about the doujinshi I was drawing, which I was drawing as black gal erotic doujin-drawing (*hard erotic), I was squeezed out without telling my parents...! I was invited to Shinna-chan's school cultural festival, and Shinna-chan dressed as a bunny girl attacked me in an empty classroom ......! ?
I hold back my voice so that she doesn't find out, but Shinna-chan's torture becomes even more intense...
