Stepsister with a big ass helped her brother with a boner

The never skinny stepsister really loves big and strong male dicks. This is exactly what she talks to her friend on the phone about. The brother, having overheard the conversation, hurries into the bedroom to measure his sexual end, which turns out to match the requirements of the curvy girl. Well, when he comes with his device to his sister and voices its parameters, she first sucks, and then uses the stray to the fullest, as befits a woman!
