My parents remarried and my new step-sister is innocent and cute, but we still have a delicate relationship where we can't open up to each other. When I invited her to my room to get closer to her, she said, "This room makes me feel strange..." and fidgeted! My step-sister started to get horny in my room where I was always masturbating, and she changed so much that she started sucking my dick forcefully! I couldn't resist the step-sister's passionate blowjob and I ejaculated, which made me so excited! When she inserted it while dripping sperm from her mouth, she started pistoning herself!
