The moment when her boobs shake the most during sex is when the man, close to ejaculation, thrusts the hardest! She swings her hips wildly to devour the greatest pleasure, and her huge boobs shake wildly in response! Her huge boobs dance like a raging horse, making the man's crotch harder and harder, and they will definitely continue to arouse him until the moment of ejaculation! This is the best part for a man to jerk off, and you can have the most satisfying ejaculation in sync!
