Sister gives her brother a gargle job and asks for help to get out of the bathtub

A young sister with blond hair accidentally pulled a muscle in her leg while in the bathroom and now she can't even stand up. But luckily there was a brother at home, whom she called for help. He, of course, came, but, for his help, the young sister not only had to take his cock in her mouth, but after that she had to promise to let him fuck her in the cunt.
