My sister is smart and has excellent grades. One day, I went to her room for something, and to my surprise… she was using porn magazines and toys to masturbate. She was touching herself or using the toy, and I was so shocked that I couldn't look away. When my sister noticed me, I thought she would be embarrassed, but instead, she called me over, touched and licked my dick, and even put it inside her pussy. Letting my sister do as she pleased, she skillfully brought me to climax.
