It was the perfect plan. You found out what your big step-sister was up to at school, what she let those boys do with her juicy tits. It was her secret, and you’d hold it against her until she gave you what you wanted. You just couldn’t get the image out of your head, not that you wanted to. Countless cocks sliding into her cleavage over and over. All of that cum drenching her chest. Now it was your turn.But your step-sister wasn’t at all surprised when you barged into her bedroom. The slut had you all figured out, she knew the score… It didn’t help that you couldn’t stop staring. Her milky tits looked so good pushed together in that tight tank top and sports bra. Your raging boner gave you away… and she took full advantage of it.She your perversion, pushed you deeper into your arousal, teased you, made you feel so wrong for even conjuring this sick plan to use her for your pleasure. She was your step-sister after all… but that wasn’t enough to stop her either. Not when she could get something out of it too. Oh, you’d get to pump your rigid cock in and out of her cleavage just like the other boys… but not for free.
