Watermelon Seeds Expand Our Breasts

We're hanging out when Lulu reveals a plate of juicy watermelon that she got for FREE! The guy seemed a bit creepy at first, she explained, but she didn't have any cash on her and he was handing out watermelons to "all of the pretty girls". All three of us tuck in, it's so yummy and we can't help but eat every last drop - seeds and all. The guy did tell Lulu to make sure that we eat the seeds, we're not quite sure why but we don't question it. Within moments we begin to feel strange. A little hot at first and then the first transformation hits - our breasts all double in size!!! "What an earth it going on???" "How is this happening??" we shriek, not quite believing it at first. But then the second wave hits us. Our skin stretches and our breasts suddenly grow absolutely MASSIVE. We realise that the fruit guy is peering through the window and so we tell him to come inside. We ask him how to reverse it, we can't possibly stay like this, our giant tits are so heavy. He tells us that the only way to shrink them again is to fuck him and extract his seed instead. Begrudgingly we agree. We play rock paper scissors to decide who is gonna go first. Lulu gives him a super sloppy blowjob, I give him a humongous titty fuck and then Lucyy tops it all off by fucking him. After we make him cum, we wait for the transformation but nothing happens. He tells us that we have to rub the remaining watermelon all over our huge boobs. We realise that we just fucked him for nothing, he lied to us and that was never part of it!!!
