My arrogant little devil niece, who looks down on me, is made to understand the meaning of sex through intense adult penetration! Despite being a brat, she's developed into a schoolgirl with H-cup breasts. Kitano Mina JUFE-451

The uncle, returning home after a long absence, was utterly astonished! His once innocent niece had transformed into a trendy J-series girl, her body incredibly sexy! And, with an air of self-importance, she declared to her NEET (neighbor) father, "In the city, I get kept by older men on a paycheck, and I even film my own pornographic videos!" The uncle was terrified by this audacious girl, but he was also captivated by her sex appeal and seduced by her audacity… He decided to teach this bold girl a lesson: adults aren't to be trifled with!
