You got caught! It's inappropriate to be looking through your step-mom's nudes on her phone, even if she's super sexy and has those huge tits! She can't help but be turned on, though.. it would be so hot if you could cum for her. She starts slow, teasing your throbbing dick through your boxers and rubbing it on her tits and ass, and she gets so turned on that she can't help but slide her fingers inside herself and starts squirting almost immediately! Be careful - don't let your dick slide inside her - She's your step-mom, after all! Stroke your cock and rub it all over her pussy while she masturbates with you and squirts on your dick over and over, with her fingers, your fingers, and a glass dildo. Kacie just keeps cumming, squirting, and screaming in ecstasy until you finally cum all over her dripping pussy and she scoops it into her mouth :)
