[Intrepid (Matsukura Nemu)] A Cheeky Gyaru Schoolgirl Gets Reformed By Her Otaku Older Brother's Cock [Full Color]

A rebellious blonde schoolgirl in a plaid uniform confronts her glasses-wearing older brother, demanding he check on her sudden breast growth and claiming he has no shame as he examines her. The encounter quickly escalates into a deeply intimate session, with the busty sister giving her sibling a messy blowjob and receiving a creamy facial, only to later confess her true feelings with a breathless "I love you too." The story takes a surprising twist as the sibling dynamic transforms into a full feline fantasy, with the reformed girl donning a lingerie catgirl outfit, a collar, and a plug tail to eagerly please her master in a hotel room.
