At the school flea market, I fancy a school sister’s bag, very good-looking. My sister offered $20, and I said $5. When she agreed, I bought it. Back in the dormitory, show my new schoolbag to my roommate. My roommate looked at me with a bad smile, and she found sex products in my bag. Like this.
I hurriedly explained and went to the flea market to give it back to my sister. But my sister has gone.
