The son stuck it in his older sister while she was reading a book.

The brother saw his sister reading a book in pantyhose with a hole in her pussy. He couldn't resist sticking it in her. Taking out his cock, he aimed it at his sister's pussy and entered her. His sister moaned loudly and forgot about the book. Her brother fucked her until she turned around and pressed his pelvis against her so that he could enter her deeper. They fucked like lovers all day until her brother gave his sister a creampie.
