Masturbating each other with my stepsister and cumming together

After watching the movie, my stepsister started to pester me. She climbed into my panties and sucked my cock. We masturbated each other and decided to fuck. My stepsister came hard while I fucked her tight pussy and vibrated her clitoris with a vibrator. We moaned loudly when we came together, simultaneously filling her body with a huge portion of sperm.
