My stepmom almost caught me fucking my stepsister with her big ass

My stepmom almost caught me fucking my stepsister with her big ass. My half-sister was having nightmares, I heard her moaning from my room. With the best of intentions I went to try to calm her down. When I got there I came across a giant tail sticking out of the blanket. She was all wet, horny, begging to be fucked like a whore. Without thinking twice to put my hard black cock in her fat pussy. When we were about to, we noticed Madras hearing everything behind the door.
