I like to spy and fuck my tattooed stepsister

For the last year these young people have been living together because their parents got married and made them step-siblings. The girl is very sensual, has black hair and many tattoos on her body that make her look tough. The young man is a little frustrated because the girlfriends he has had have left him for better looking men, so now he plays video games and stays home every weekend. His stepsister makes him very horny and he likes to spy on her while she dresses, and he is sure they will soon fuck because she is also attracted to him. One afternoon he spies on her while she is changing clothes. She visits him in his room and starts stroking his penis and tells him straight out that she wants to fuck him.
