Teen is surprised to see his brother's big cock

This teen's brother comes to the shower when she is in the bathtub and instead of saying anything, what she does is stay hidden to spy on him. That's when he discovers his brother's big cock, bigger than she had imagined. He thinks a lot about what to do and in the end he shows up in front of him to give him a blowjob and try his cock. The brother has it so hard that he does not even consider if what they are doing is right, so he places it on his back and begins to penetrate it with great desire, going through several positions while nailing it very hard.
