I heard your cum has... special properties. If I rub it into my tits, it will make them even bigger! My tits are already pretty big, but I want them to be even bigger, and so I beg for you to cum all over them. I ask you to imagine your cock between my tits, helping them grow larger, treating me like a slut,them in your cum... I finally give you a cum countdown to help you spray your load all over my breasts. As I rub your cum into my tits, I feel them absorbing and expanding! Finally, I try on the bra I wore earlier to see how much bigger they've gotten... I will definitely want more favors like this in the future
