My sister came over because she was worried about me living alone! Unlike me, she's cute and does housework perfectly! But it bothers me because her plump ass and panties are everywhere, whether she's unguarded or purposely showing them off! She even takes care of my erect cock, licking and sucking it with her mouth as if enjoying my reaction! I couldn't resist! It's my brother's job to make my sister's pussy feel good!
