In the heat of the moment, Jason and Jax's sibling rivalry melts away, replaced by a primal desire. Jax, a jock with a body honed by years of rigorous training, can't help but notice Jason's lithe form, glistening with sweat. Jason, always the eager one, takes Jax's cock into his mouth, savoring the salty taste of his stepbrother's workout. Jax, overcome with lust, flips Jason over and buries his face in Jason's ass, preparing him for what's to come. With a grunt, Jax enters Jason, his huge cock stretching Jason's hole. They fuck in a frenzy, their bodies slapping together, until they both reach their peak, their cum mixing and dripping down Jason's thighs.
