You and your stepsister are on a vacation trip with the family. In the morning she decides to do her yoga downstairs in the living room, wearing just a thong and a small shirt. She doesn’t notice you coming in. The view you see is more than what you expected that morning, you noticed how pretty your sister is and that she have a perfect body but you leave before she notices you. The thoughts kept going through your head. She innocently goes to your room and realize that you, his brother can't stop watching her body. One thing leads to another and you begin to play and tease each other until she begins to suck and fuck your cock until she makes you explode.
