I come into your room, slightly embarrassed, but desperate... I've been putting off asking you. I'm so so desperate for bigger tits, they're just so small and saggy, I won't ever be able to afford a tit job, I know this is so wrong to ask.. but I have read once that a stepson's semen can make a stepmother's breasts grow. Please help me... I know what you get up to in your room anyway.. just maybe cum in a cup and I will take it away or something. Or maybe I could give you a blowjob, bet you've not had one of those before, so make it mutually beneficial for us. I come over, begin sucking your cock, and in no time you're coming in my mouth, and instantly my tits grow Wow! They look so good. As I'm admiring them in the mirror, I turn around a notice your cock getting hard again, you convince me that maybe another go will grow them even bigger. I'm straight back on my knees sucking you off. And once again, another mouthful makes my tits even bigger! They're perfect.
