I have a younger sister. Once she decides to do something, she is a tenacious person who will see it through to the end. But when she decided to work in a soapland, the relationship between my brother and sister changed. In order to become No. 1, she uses me as a practice dummy and plays with me in soapland regardless of time or place, so it's a big deal! Even during class, she brings a dirty chair and gives me a handjob and a titty fuck, and after school she brings a mat and plays with me with lotion, making me cum over and over again. I never thought I'd get to experience scrubbing, washing a pot, and using a periscope with my younger sister (sweat).
