I met my sister for the first time in a while and she was sleeping defenselessly. I usually don't care, but even though I know it's not good, I couldn't help but peek, touch her, and jerk off.... Damn! I woke up! My dick was out, so I can't make any excuses! But we're usually good siblings, so I had no choice but to help her out and rub my penis against her. Huh? Is she wet? It's in! It's about to come out!
