When I went to my friend's house, my friend's sister treated me like a kid and showed me her defenseless miniskirt panties. The next day, when I went to play again, my friend was out and my sister invited me to come to her room and show me her panties. My sister is a shotacon and can't wait to play with me. She presses her big boobs and big ass against my face and enjoys the reaction of my dick. She hands me a video camera and whispers to me, "You can take whatever you want to see." She even showed me her masturbation, so I couldn't hold back any longer and attacked her, pounding her until she was exhausted.
