My step-sister is cute but has a very aggressive personality, and she hates me for being weak! One night when my parents were not around, there was a power outage due to a storm, and the whole house was in darkness! Then, my step-sister came into my room with a cute atmosphere different from usual and asked, "Can I stay with you until the lights come on?" I got a full erection with my frightened step-sister and I was super close to her in the room! And I was found out immediately! But, my step-sister touched my erect cock while fidgeting, so we had a divine sex!
