Stepsister's unexpected oral surprise leads to intense orgasm

When the young guy returns home, he finds his stepsister casually watching TV. As he gets closer, he notices her acting a bit strange. In a shocking twist, she drops to her knees and starts sucking on his cock. The poor guy is stunned and can't believe what's happening. His stepsister, it turns out, is a total nympho and she's been waiting all day for this moment. She's been craving his cock and now that she has it, she's not letting go. She takes him deep into her mouth, making him moan in pleasure. After a bit of sucking, she decides to ride him. She climbs on top and starts riding him like a pro. Her pussy is so tight that he can't hold back and he shoots his load all over her. The girl, not being his sister, doesn't mind and even licks up the cum. The young couple then proceeds to have some more wild sex, leaving the guy completely satisfied.
