I returned home after a long time to find my sister Kana, who had divorced and turned into a NEET. Unlike her past self, who was responsible and beautiful, she is now spoiled and impossible to handle. Even our mother, who had been at her wits' end, won't be coming back for a while. My sister flaunted her breasts in front of me, causing me to involuntarily get an erection... She, who has been playing erotic games all day and accumulating sexual desire, is extremely interested in my grown-up dick! Her sense of ethics is also broken, turning me, her brother, into a dildo toy! Even though I know it's wrong, I can't help but ejaculate inside her as she enjoys my penis deep within her womb. Since then, my sister and I have been going at it like crazy from morning till dawn in the living room, bathroom, and her bedroom...!
