My little sister, who usually clings to me and acts spoiled… Recently, there are moments when I can't help but see her as a woman… At times like that, I always get an erection. I thought it would be bad if my sister saw me erect, but she didn't find it disgusting at all; instead, she got incredibly excited about my erect dick! She was breathing heavily while that super shy sister of mine made a face and said, "I want to try putting brother's big cock inside me." The development was too ideal, making my crotch rock hard!
