After years away from home, I finally returned to my parents' house. My sister, who still doesn't work but spends her days being lazy, hasn't changed much. However, there was one thing that caught my eye—her huge ass has always been incredibly erotic, making it impossible for me not to get turned on by it. To make matters worse, I accidentally saw her masturbating! Unable to control myself any longer, I forced myself onto her, giving her a creampie sex! From then on, whenever I felt horny during my stay at their place, I would sneak off and fuck her brains out! In the hallway, I rubbed my dick against her plump ass before shooting my load inside her pussy! Even though she kept saying no, I made sure to give her multiple orgasms with my brother's cock! Since they never had sex back when we lived together, I decided to treat them both to some really good fucking!
