I met my sister for the first time in a while and she was sleeping defenselessly. I thought to myself that she had developed into a woman without me even realizing it. I touched her and masturbated even though I knew it was wrong... What a shame! She woke up! My dick was out so I had no excuse! But surprisingly, she offered to help me and rubbed it against me! What? Is she wet? What a shame! It went in! I was about to come out!
