My cock-hungry adult stepsister cannot go a day without sex, so whenever she has no partner, she uses me to satisfy herself. I protest that even as stepsiblings, raw creampies go too far. She promises I can pull out whenever I am close, but as she cums repeatedly, she clamps both arms around my neck. There is no way to escape her DDT lock, and I am forced to ejaculate deep inside. Her promise was a lie—she planned to take my load from the beginning.
