I come into your room, slightly embarrassed, but desperate.. I've been putting off asking you, but I just cant forget about it. I'm so so desperate for bigger tits, they're just so small and saggy, i wont ever be able to afford a tit job, I know this is so wrong to ask.. but I have read once that a son's semen can make a mother 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. Orrrr maybe I could give you a blowjob, bet you've not had one of those before, 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, I cannot believe it. Wow! They look so good. I'm over the moon. 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 hadn't even thought of that, I'm straight back on my knees sucking you off. And once again, another mouthful makes my tits even bigger! Wooowww, just look at them, they're perfect. But then I hear your dad getting home, oh no, I hadn't thought this through had I. But then things take a turn...
