[Chinese]FPRE-056 "Just lend me the tip for 3cm" Unable to resist my sister-in-law's forceful demand, it escalated into big-ass cowgirl and a creampie! Hinatori Hina

I secured a job in my hometown and ended up returning to my parents' house, marking the start of tumultuous days. The biggest change was that my parents remarried, and I gained a younger sister. Moreover, three months ago, it was decided that my father would be transferred, leaving me and my sister to stay in this house alone. My sister Hinachi dropped out of university and has been a recluse ever since. However, during the summer, her room's air conditioner broke down, and seeing me drenched in sweat triggered her repressed desires, causing her to suddenly transform. She pounced on me saying, "Big brother, just lend me the tip!"
